FIELD OF THE INVENTION
[0001] The present disclosure relates to a mountable fan filter assembly, and more particularly
to a mountable fan filter assembly for implementing air pollution detection and complete
purification in an indoor field.
BACKGROUND OF THE INVENTION
[0002] Suspended particles are defined as the solid particles or droplets contained in the
air. Due to their extremely fine size, the suspended particles may enter the lungs
of human body through the nasal hair in the nasal cavity easily, causing inflammation
in the lungs, asthma or cardiovascular disease. If other pollutant compounds are attached
to the suspended particles, it will further increase the harm to the respiratory system.
In recent years, the issue of air pollution has been increasingly severe, especially
with consistently high concentrations of suspended particles (e.g., PM2.5). Therefore,
the monitoring to the concentration of the gas suspended particles is taken more and
more seriously. However, the gas flows unstably due to the variable wind direction
and the air volume, and the general gas-quality monitoring station is located in a
fixed place. Under this circumstance, it is impossible for people to check the concentration
of suspended particles in current environment.
[0003] Furthermore, in recent years, modern people are placing increasing importance on
the quality of the air in their surroundings. For example, carbon monoxide, carbon
dioxide, volatile organic compounds (VOC), PM2.5, nitric oxide, sulfur monoxide and
even the suspended particles contained in the air are exposed in the environment to
affect the human health, and even endanger the life seriously. Therefore, the quality
of environmental air has attracted the attention of various countries. At present,
how to detect the air quality and avoid the harm is a crucial issue that urgently
needs to be solved.
[0004] In order to confirm the quality of the air, it is feasible to use a gas sensor to
detect the air surrounding in the environment. If the detection information can be
provided in real time to warn the people in the environment, it is helpful of avoiding
the harm and facilitates the people to escape the hazard immediately, preventing the
hazardous gas exposed in the environment from affecting the human health and causing
the harm. Therefore, it is considered a valuable application to use a gas sensor detecting
the air in the surrounding environment.
[0005] In addition, it is difficult to have the surveillance and control the indoor air
quality. Besides the outdoor air quality, the indoor air-conditioning conditions and
the pollution sources are the major factors affecting the indoor air quality. It is
necessary to intelligently and quickly detect indoor air pollution sources in various
indoor fields, effectively remove the indoor air pollution to form a clean and safe
breathing gas state, and monitor indoor air quality in real time anytime, anywhere.
Certainly, if the concentration of the suspended particles in the indoor field is
strictly controlled according to the "clean room" standard, it allows avoiding the
introduction, generation and retention of suspended particles, and the temperature
and humidity in the indoor field can be controlled within the required range, and
thus, the indoor field can meet the clean room requirements for safe breathing.
[0006] Therefore, it is a main subject in the present disclosure to develop a mountable
fan filter assembly which provides a solution of detecting the indoor air quality
and solving the problem of air pollution, so that the indoor field can meet the clean
room requirements, and the impact and injury for human health caused by the gas hazards
in the environment can be avoided.
SUMMARY OF THE INVENTION
[0007] One object of the present disclosure is to provide a mountable fan filter assembly
for implementing air pollution detection and complete purification in the space of
an indoor field. The mountable fan filter assembly is equipped with at least one gas
detector, at least one air guiding fan, at least one filter component, a driving controller
and a flow guiding pathway which is design without piping. Moreover, the flow guiding
pathway is fluidly communicated with a circulating return air port and a filter duct,
the circulating return air port and filter duct are fluidly communicated with the
indoor field, and the at least one air guiding fan and the at least one filter component
are arranged under the filter duct. The gas detector is electrically connected to
the driving controller and connected to a networked cloud computing service device
of the indoor air cleaning network mechanism to form an intelligent linkage system.
At this time, the gas detector receives a control instruction from the networked cloud
computing service device of the indoor air cleaning network mechanism through an Internet
of Things communication, and controls actuation operation of the air guiding fan,
so that air in the indoor field is introduced through the circulating return air port
and passed the flow guiding pathway into the filter duct. In that, air pollution is
filtered and purified through the at least one filter component under the filter duct,
and the filtered air is introduced into the indoor field for multiple cycles, so as
to implement circulation filtration and purification treatment in real time, prevent
the backflow of the filtered gas effectively, and achieve complete clean room treatment.
At the same time, the air pollution in the space of the indoor field is detected by
intelligently comparing the ambient air quality status, and the air guiding fan is
instantly controlled to adjust the air flow volume according to the air quality, thereby
effectively adjusting the energy-saving efficiency of the operation of the mountable
fan filter assembly. Consequently, the air flow volume noise reaches zero specification
value, thereby achieving the ultimate environmental protection of balanced energy
saving and power saving. The present disclosure includes the industrial applicability
and the inventive steps.
[0008] In accordance with an aspect of the present disclosure, a mountable fan filter assembly
used in an indoor air cleaning network mechanism is provided, and includes at least
one gas detector and a unit main part. The at least one gas detector is arranged in
an indoor field for detecting air pollution information and temperature and humidity
information of gas. The unit main part is built-in and suspended in the indoor field
and comprises at least one air guiding fan, at least one filter component, a driving
controller and a flow guiding pathway. The flow guiding pathway is fluidly communicated
with a circulating return air port and a filter duct, the circulating return air port
and filter duct are fluidly communicated with the indoor field. The flow guiding pathway
is horizontally parallel to and separated from the filter duct. Wherein, the at least
one air guiding fan and the at least one filter component are arranged under the filter
duct. Moreover, the at least one gas detector is electrically connected to the driving
controller. The at least one gas detector receives a control instruction and transmits
it to the driving controller through an Internet of Things communication, so as to
control the driving controller to enable an actuation operation of the at least one
air guiding fan. Consequently, air in the indoor field is introduced through the circulating
return air port and passed the flow guiding pathway into the filter duct. In that,

the filter duct, and the filtered air is introduced into the indoor field for multiple
cycles, so as to implement circulation filtration and purification treatment in real
time, prevent the backflow of the filtered gas effectively, and achieve complete clean
room treatment.

In the embodiment, the clean room level of the indoor field A is ZAPClean Room 1~12.
In some embodiments, the air pollution information of the indoor field A and the outdoor
field is air pollution data of carbon dioxide (CO
2), and ventilation is performed to achieve a zero difference of carbon dioxide (CO
2) between the indoor field A and the outdoor field B. In other embodiments, the mountable
fan filter assembly is a fresh air fan, a full heat exchanger, or a heating, ventilation
and air conditioning (HVAC), but not limited to.
[0013] Please refer to FIG. 1B. The mountable fan filter assembly is used in an indoor air

of Things communication, stores and constructs an air pollution big data database
accordingly, and intelligently selects to issue the control instruction to the detector
1, so as to control the driving controller 23 to enable the actuation operation of
the air guiding fan 21. Consequently, air in the indoor field A is ventilated, the
temperature and the humidity are adjusted, and air pollution is guided through the
filter component 22 for multiple cycles of purification and complete clean room treatment,
so as to achieve complete clean room treatment, and the gas detector 1 externally

[0014] In the embodiment, the at least one gas detector 1 is arranged in an indoor field
A and an outdoor field B to detect air pollution information. The at least one gas
detector 1 also outputs the air pollution information through Internet of Things (IoT)
communication. Notably, in the embodiment, the gas detector 1 includes a gas detection
module disposed therein. Please refer to FIG. 3A and FIG. 3B. Preferably but not exclusively,
the gas detector 1 is formed by a type of structure including an external power terminal,
which can be directly inserted into the power interface in the indoor field A to start
the operation of detecting air pollution. In an embodiment, as shown in FIG. 3C, a
type of the gas detection module without an external power terminal is directly constructed
on a gas molecule control hardware device (e.g., the mountable fan filter assembly,
the mountable gas exchange device 4, the purifier 5, the exhaust device 6, the extractor
hood system 7, the air conditioning device 8, the vacuum cleaner 9 and the dehumidifier
10) and connected to a driving controller 23. A control instruction is received for
the driving controller 23 to control the power supply of the gas molecule control
hardware device and control actuation operation of the air guiding fan 21.
[0015] In the embodiment, Internet of Things communication refers to a collective network,
which connects various devices and technologies and helps the devices communicate
with the cloud and with each other. Preferably but not exclusively, the IoT communication
is a wired communication, which is connected to the networked cloud computing service
device 3 via a wired line. Preferably but not exclusively, the IoT communication is
a wireless communication for communicating with the networked cloud computing service
device 3 via a wireless connection. The wireless communication transmission includes
one selected from the group consisting of a Wi-Fi module, a Bluetooth module, a radio
frequency identification module, and a near field communication (NFC) module.
[0016] Notably, in the embodiment, the air pollution is at least one selected from the group
consisting of particulate matter, carbon monoxide, carbon dioxide, ozone, sulfur dioxide,
nitrogen dioxide, lead, total volatile organic compounds (TVOC), formaldehyde, bacteria,
fungi, virus and a combination thereof.
[0017] Certainly, the gas detector 1 monitors the air quality in the space of the indoor
field A anytime and anywhere. Moreover, at the same time, the air pollution information
in the space of the indoor field A is transmitted to the air pollution big data database
of the networked cloud computing service device 3 to intelligently compare the ambient
air quality status, and instantly control the air guiding fan 21 arranged in each
area to adjust the air volume according to the air quality. The energy-saving benefits
of the operation of the gas molecule control hardware device are effectively controlled.
[0018] In the present disclosure, the specific implementation of the mountable fan filter
assembly is understandable, and the structure of the gas detection module of the gas
detector 1 of the present disclosure is described in detail below. Please refer to
FIG. 3A to FIG. 11. In the embodiment, the gas detection module includes a controlling
circuit board 11, a gas detection main part 12, a microprocessor 13 and a communicator
14. The gas detection main part 12, the microprocessor 13 and the communicator 14
are integrally packaged on the controlling circuit board 11 and electrically connected
to each other. In the embodiment, the microprocessor 13 and the communicator 14 are
mounted on the controlling circuit board 11. The microprocessor 13 controls the driving
signal of the gas detection main part 12 for enabling the detection. In this way,
the gas detection main part 12 detects the air pollution and outputs the air pollution
information, and the microprocessor 13 receives, processes and provides the air pollution
information to the communicator 14 for a communication transmission externally, and
transmitting to the cloud computing server device 3 through IoT (Internet of Things)
communication.
[0019] Please refer to FIG. 4A to FIG. 9A. In the embodiment, the gas detection main part
12 includes a base 121, a piezoelectric actuator 122, a driving circuit board 123,
a laser component 124, a particulate sensor 125, and an outer cover 126. In the embodiment,
the base 121 includes a first surface 1211, a second surface 1212, a laser loading
region 1213, a gas-inlet groove 1214, a gas-guiding-component loading region 1215
and a gas-outlet groove 1216. The first surface 1211 and the second surface 1212 are
two surfaces opposite to each other. In the embodiment, the laser loading region 1213
is hollowed out from the first surface 1211 toward the second surface 1212. The outer
cover 126 covers the base 121 and includes a side plate 1261. The side plate 1261
has an inlet opening 1261a and an outlet opening 1261b. The gas-inlet groove 1214
is concavely formed from the second surface 1212 and disposed adjacent to the laser
loading region 1213. The gas-inlet groove 1214 includes a gas-inlet 1214a and two
lateral walls. The gas-inlet 1214a is in communication with an environment outside
the base 121, and is spatially corresponding in position to an inlet opening 1261a
of the outer cover 126. Two transparent windows 1214b are opened on the two lateral
walls of the gas-inlet groove 1214 and are in communication with the laser loading
region 1213. Therefore, the first surface 1211 of the base 121 is covered and attached
by the outer cover 126, and the second surface 1212 is covered and attached by the
driving circuit board 123, so that an inlet path is defined by the gas-inlet groove
1214. In the embodiment, the gas-guiding-component loading region 1215 mentioned above
is concavely formed from the second surface 1212 and in communication with the gas-inlet
groove 1214. A ventilation hole 1215a penetrates a bottom surface of the gas-guiding-component
loading region 1215. The gas-guiding-component loading region 1215 includes four positioning
protrusions 1215b disposed at four corners of the gas-guiding-component loading region
1215, respectively. In the embodiment, the gas-outlet groove 1216 includes a gas-outlet
1216a, and the gas-outlet 1216a is spatially corresponding to the outlet opening 1261b
of the outer cover 126. The gas-outlet groove 1216 includes a first section 1216b
and a second section 1216c. The first section 1216b is concavely formed out from the
first surface 1211 in a region spatially corresponding to a vertical projection area
of the gas-guiding-component loading region 1215. The second section 1216c is hollowed
out from the first surface 1211 to the second surface 1212 in a region where the first
surface 1211 is extended from the vertical projection area of the gas-guiding-component
loading region 1215. The first section 1216b and the second section 1216c are connected
to form a stepped structure. Moreover, the first section 1216b of the gas-outlet groove
1216 is in communication with the ventilation hole 1215a of the gas-guiding-component
loading region 1215, and the second section 1216c of the gas-outlet groove 1216 is
in communication with the gas-outlet 1216a. In that, when first surface 1211 of the
base 121 is attached and covered by the outer cover 126 and the second surface 1212
of the base 121 is attached and covered by the driving circuit board 123, the gas-outlet
groove 1216 and the driving circuit board 123 collaboratively define an outlet path.
[0020] In the embodiment, the laser component 124 and the particulate sensor 125 are disposed
on and electrically connected to the driving circuit board 123 and located within
the base 121. In order to clearly describe and illustrate the positions of the laser
component 124 and the particulate sensor 125 in the base 121, the driving circuit
board 123 is intentionally omitted. The laser component 124 is accommodated in the
laser loading region 1213 of the base 121, and the particulate sensor 125 is accommodated
in the gas-inlet groove 1214 of the base 121 and is aligned to the laser component
124. In addition, the laser component 124 is spatially corresponding to the transparent
window 1214b, therefore, a light beam emitted by the laser component 124 passes through
the transparent window 1214b and is irradiated into the gas-inlet groove 1214. A light
beam path emitted from the laser component 124 passes through the transparent window
1214b and extends in an orthogonal direction perpendicular to the gas-inlet groove
1214. In the embodiment, a projecting light beam emitted from the laser component
124 passes through the transparent window 1214b and enters the gas-inlet groove 1214
to irradiate the suspended particles contained in the gas passing through the gas-inlet
groove 1214. When the suspended particles contained in the gas are irradiated and
generate scattered light spots, the scattered light spots are received and calculated
by the particulate sensor 125 to obtain the gas detection information.
[0021] In the embodiment, the piezoelectric actuator 122 is accommodated in the square-shaped
gas-guiding-component loading region 1215 of the base 121. In addition, the gas-guiding-component
loading region 1215 of the base 121 is in fluid communication with the gas-inlet groove
1214. When the piezoelectric actuator 122 is enabled, the gas in the gas-inlet groove
1214 is inhaled by the piezoelectric actuator 122, so that the gas flows into the
piezoelectric actuator 122, and is transported into the gas-outlet groove 1216 through
the ventilation hole 1215a of the gas-guiding-component loading region 1215. Moreover,
the driving circuit board 123 covers the second surface 1212 of the base 121, and
the laser component 124 is disposed on the driving circuit board 123, and is electrically
connected to the driving circuit board 123. The particulate sensor 125 is also disposed
on the driving circuit board 123 and electrically connected to the driving circuit
board 123. In that, when the outer cover 126 covers the base 121, the inlet opening
1261a is spatially corresponding to the gas-inlet 1214a of the base 121, and the outlet
opening 126lb is spatially corresponding to the gas-outlet 1216a of the base 121.
[0022] In the embodiment, the piezoelectric actuator 122 includes a gas-injection plate
1221, a chamber frame 1222, an actuator element 1223, an insulation frame 1224 and
a conductive frame 1225. In the embodiment, the gas-injection plate 1221 is made by
a flexible material and includes a suspension plate 1221a and a hollow aperture 1221b.
The suspension plate 1221a is a sheet structure and is permitted to undergo a bending
deformation. Preferably but not exclusively, the shape and the size of the suspension
plate 1221a are accommodated in the inner edge of the gas-guiding-component loading
region 1215, but not limited thereto. The hollow aperture 1221b passes through a center
of the suspension plate 1221a, so as to allow the gas to flow therethrough. Preferably
but not exclusively, in the embodiment, the shape of the suspension plate 1221a is
selected from the group consisting of a square, a circle, an ellipse, a triangle and
a polygon, but not limited thereto.
[0023] In the embodiment, the chamber frame 1222 is carried and stacked on the gas-injection
plate 1221. In addition, the shape of the chamber frame 1222 is corresponding to the
gas-injection plate 1221. The actuator element 1223 is carried and stacked on the
chamber frame 1222. A resonance chamber 1226 is collaboratively defined by the actuator
element 1223, the chamber frame 1222 and the suspension plate 1221a and is formed
between the actuator element 1223, the chamber frame 1222 and the suspension plate
1221a. The insulation frame 1224 is carried and stacked on the actuator element 1223
and the appearance of the insulation frame 1224 is similar to that of the chamber
frame 1222. The conductive frame 1225 is carried and stacked on the insulation frame
1224, and the appearance of the conductive frame 1225 is similar to that of the insulation
frame 1224. In addition, the conductive frame 1225 includes a conducting pin 1225a
and a conducting electrode 1225b. The conducting pin 1225a is extended outwardly from
an outer edge of the conductive frame 1225, and the conducting electrode 1225b is
extended inwardly from an inner edge of the conductive frame 1225. Moreover, the actuator
element 1223 further includes a piezoelectric carrying plate 1223a, an adjusting resonance
plate 1223b and a piezoelectric plate 1223c. The piezoelectric carrying plate 1223a
is carried and stacked on the chamber frame 1222. The adjusting resonance plate 1223b
is carried and stacked on the piezoelectric carrying plate 1223a. The piezoelectric
plate 1223c is carried and stacked on the adjusting resonance plate 1223b. The adjusting
resonance plate 1223b and the piezoelectric plate 1223c are accommodated in the insulation
frame 1224. The conducting electrode 1225b of the conductive frame 1225 is electrically
connected to the piezoelectric plate 1223c. In the embodiment, the piezoelectric carrying
plate 1223a and the adjusting resonance plate 1223b are made by a conductive material.
The piezoelectric carrying plate 1223a includes a piezoelectric pin 1223d. The piezoelectric
pin 1223d and the conducting pin 1225a are electrically connected to a driving circuit
(not shown) of the driving circuit board 123, so as to receive a driving signal, such
as a driving frequency and a driving voltage. Through this structure, a circuit is
formed by the piezoelectric pin 1223d, the piezoelectric carrying plate 1223a, the
adjusting resonance plate 1223b, the piezoelectric plate 1223c, the conducting electrode
1225b, the conductive frame 1225 and the conducting pin 1225a for transmitting the
driving signal. Moreover, the insulation frame 1224 is insulated between the conductive
frame 1225 and the actuator element 1223, so as to avoid the occurrence of a short
circuit. Thereby, the driving signal is transmitted to the piezoelectric plate 1223c.
After receiving the driving signal such as the driving frequency and the driving voltage,
the piezoelectric plate 1223c deforms due to the piezoelectric effect, and the piezoelectric
carrying plate 1223a and the adjusting resonance plate 1223b are further driven to
generate the bending deformation in the reciprocating manner.
[0024] Furthermore, in the embodiment, the adjusting resonance plate 1223b is located between
the piezoelectric plate 1223c and the piezoelectric carrying plate 1223a and served
as a cushion between the piezoelectric plate 1223c and the piezoelectric carrying
plate 1223a. Thereby, the vibration frequency of the piezoelectric carrying plate
1223a is adjustable. Basically, the thickness of the adjusting resonance plate 1223b
is greater than the thickness of the piezoelectric carrying plate 1223a, and the vibration
frequency of the actuator element 1223 can be adjusted by adjusting the thickness
of the adjusting resonance plate 1223b.
[0025] Please further refer to FIG. 7A, FIG. 7B, FIG.8A, FIG. 8B and FIG. 9A. In the embodiment,
the gas-injection plate 1221, the chamber frame 1222, the actuator element 1223, the
insulation frame 1224 and the conductive frame 1225 are stacked and positioned in
the gas-guiding-component loading region 1215 sequentially, so that the piezoelectric
actuator 122 is supported and positioned in the gas-guiding-component loading region
1215. A plurality of clearances 1221c are defined between the suspension plate 1221a
of the gas-injection plate 1221 and an inner edge of the gas-guiding-component loading
region 1215 for gas flowing therethrough. In the embodiment, a flowing chamber 1227
is formed between the gas-injection plate 1221 and the bottom surface of the gas-guiding-component
loading region 1215. The flowing chamber 1227 is in communication with the resonance
chamber 1226 between the actuator element 1223, the chamber frame 1222 and the suspension
plate 1221a through the hollow aperture 1221b of the gas-injection plate 1221. By
controlling the vibration frequency of the gas in the resonance chamber 1226 to be
close to the vibration frequency of the suspension plate 1221a, the Helmholtz resonance
effect is generated between the resonance chamber 1226 and the suspension plate 1221a,
so as to improve the efficiency of gas transportation. When the piezoelectric plate
1223c is moved away from the bottom surface of the gas-guiding-component loading region
1215, the suspension plate 1221a of the gas-injection plate 1221 is driven to move
away from the bottom surface of the gas-guiding-component loading region 1215 by the
piezoelectric plate 1223c. In that, the volume of the flowing chamber 1227 is expanded
rapidly, the internal pressure of the flowing chamber 1227 is decreased to form a
negative pressure, and the gas outside the piezoelectric actuator 122 is inhaled through
the clearances 1221c and enters the resonance chamber 1226 through the hollow aperture
1221b. Consequently, the pressure in the resonance chamber 1226 is increased to generate
a pressure gradient. When the suspension plate 1221a of the gas-injection plate 1221
is driven by the piezoelectric plate 1223c to move toward the bottom surface of the
gas-guiding-component loading region 1215, the gas in the resonance chamber 1226 is
discharged out rapidly through the hollow aperture 1221b, and the gas in the flowing
chamber 1227 is compressed, thereby the converged gas is quickly and massively ejected
out of the flowing chamber 1227 under the condition close to an ideal gas state of
the Benulli's law, and transported to the ventilation hole 1215a of the gas-guiding-component
loading region 1215.
[0026] By repeating the above operation steps shown in FIG. 9B and FIG. 9C, the piezoelectric
plate 1223c is driven to generate the bending deformation in a reciprocating manner.
According to the principle of inertia, since the gas pressure inside the resonance
chamber 1226 is lower than the equilibrium gas pressure after the converged gas is
ejected out, the gas is introduced into the resonance chamber 1226 again. Moreover,
the vibration frequency of the gas in the resonance chamber 1226 is controlled to
be close to the vibration frequency of the piezoelectric plate 1223c, so as to generate
the Helmholtz resonance effect to achieve the gas transportation at high speed and
in large quantities. The gas is inhaled through the gas-inlet 1214a on the outer cover
126, flows into the gas-inlet groove 1214 of the base 121 through the gas-inlet 1214a,
and is transported to the position of the particulate sensor 125. The piezoelectric
actuator 122 is enabled continuously to inhale the gas into the inlet path, and facilitate
the gas outside the gas detection module to be introduced rapidly, flow stably, and
transported above the particulate sensor 125. At this time, a projecting light beam
emitted from the laser component 124 passes through the transparent window 1214b to
irritate the suspended particles contained in the gas flowing above the particulate
sensor 125 in the gas-inlet groove 1214. When the suspended particles contained in
the gas are irradiated and generate scattered light spots, the scattered light spots
are received and calculated by the particulate sensor 125 for obtaining related information
about the sizes and the concentration of the suspended particles contained in the
gas. Moreover, the gas above the particulate sensor 125 is continuously driven and
transported by the piezoelectric actuator 122, flows into the ventilation hole 1215a
of the gas-guiding-component loading region 1215, and is transported to the gas-outlet
groove 1216. At last, after the gas flows into the gas outlet groove 1216, the gas
is continuously transported into the gas-outlet groove 1216 by the piezoelectric actuator
122, and thus the gas in the gas-outlet groove 1216 is pushed to discharge through
the gas-outlet 1216a and the outlet opening 1261b.
[0027] The gas detector 1 of the present disclosure not only can detect the particulate
matters in the gas, but also can detect the gas characteristics of the introduced
gas, for example, to determine whether the gas is formaldehyde, ammonia, carbon monoxide,
carbon dioxide, oxygen, ozone, or the like. Therefore, in one or some embodiments,
the gas detector 1 of the present disclosure further includes a gas sensor 127 positioned
and disposed on the driving circuit board 123, electrically connected to the driving
circuit board 123, and accommodated in the gas-outlet groove 1216, so as to detect
the air pollution introduced into the gas-outlet groove 1216. Preferably but not exclusively,
in an embodiment, the gas sensor 127 includes a volatile-organic-compound sensor for
detecting the information of carbon dioxide (CO
2) or volatile organic compounds (TVOC). Preferably but not exclusively, in an embodiment,
the gas sensor 127 includes a formaldehyde sensor for detecting the information of
formaldehyde (HCHO) gas. Preferably but not exclusively, in an embodiment, the gas
sensor 127 includes a bacteria sensor for detecting the information of bacteria or
fungi. Preferably but not exclusively, in an embodiment, the gas sensor 127 includes
a virus sensor for detecting the information of virus in the gas. Preferably but not
exclusively, the gas sensor 127 is a temperature and humidity sensor for detecting
the temperature and humidity information of the gas.
[0028] Please refer to FIG. 2. In the embodiment, the air guiding fan 21 of the mountable
fan filter assembly is controlled to start and guide the air pollution to pass through
the filter component 22 for filtration. Preferably but not exclusively, the filter
component 22 is a filter with a grade of minimum filtration efficiency value (MREV)
8 or above, or a filter with high-efficiency particulate air (HEPA) grade, which is
configured to absorb the chemical smoke, the bacteria, the dust particles and the
pollen contained in the air pollution, so that the air pollution introduced into the
filter component 22 is filtered and purified to achieve the effect of filtering and
purification. Notably, in the present disclosure, the filter with the high efficiency
particulate air (HEPA) grade is of 10 or above, and has a dust holding capacity greater
than 12,000 mg. In an embodiment, the filter component 22 of the present disclosure
is further combined with physical or chemical materials to provide a sterilization
effect on the air pollution, and the airflow of the air guiding fan 21 flows in the
path indicated by the arrow. In an embodiment, the filter component 22 includes a
decomposition layer coated thereon to sterilize in chemical means. Preferably but
not exclusively, the decomposition layer includes an activated carbon 22a configured
to remove organic and inorganic substances in air pollution, and remove colored and
odorous substances. Preferably but not exclusively, the activated carbon has a formaldehyde
absorption capacity greater than 1,500 mg. In an embodiment, the decomposition layer
includes a cleansing factor containing chlorine dioxide layer 22b configured to inhibit
viruses, bacteria, fungi, influenza A, influenza B, enterovirus and norovirus in the
air pollution, and the inhibition ratio can reach 99% and more, thereby reducing the
cross-infection of viruses. In an embodiment, the decomposition layer includes an
herbal protective layer 22c extracted from ginkgo and Japanese Rhus chinensis configured
to resist allergy effectively and destroy a surface protein of influenza virus (such
as H1N1 influenza virus) passing therethrough. In an embodiment, the decomposition

contained in the air pollution. In an embodiment, the decomposition layer includes
a zeolite 22e configured to remove ammonia nitrogen, heavy metals, organic pollutants,

embodiments, the filter component 22 is combined with a light irradiation element
to sterilize in chemical means. Preferably but not exclusively, the light irradiation
element is a photo-catalyst unit including a photo catalyst 22f and an ultraviolet
lamp 22g. When the photo catalyst 22f is irradiated by the ultraviolet lamp 22g, the
light energy is converted into the chemical energy, thereby decomposes harmful gases
and disinfects bacteria contained in the air pollution, so as to achieve the effects
of filtering and purifying. Notably, the power of the ultraviolet lamp 22g in the
present disclosure is more than 120 mw. In an embodiment, the light irradiation element
is a photo-plasma unit including a nanometer irradiation tube 22h. When the introduced
air pollution is irradiated by the nanometer irradiation tube 22h, the oxygen molecules
and water molecules contained in the air pollution are decomposed into high oxidizing
photo-plasma, and an ion flow capable of destroying organic molecules is generated.
In that, volatile formaldehyde, volatile toluene and volatile organic compounds (VOC)
contained in the air pollution are decomposed into water and carbon dioxide, so as
to achieve the effects of filtering and purifying. Moreover, in some embodiments,
the filter component 22 is combined with a decomposition unit to sterilize in chemical
means. Preferably but not exclusively, the decomposition unit is a negative ion unit
22i with a dust collecting plate. It makes the suspended particles in the air pollution
to carry with positive charge and adhered to the dust collecting plate carry with
negative charges, so as to achieve the effects of filtering and purifying. Preferably
but not exclusively, the decomposition unit is a plasma ion unit 22j. The oxygen molecules
and water molecules contained in the air pollution are decomposed into positive hydrogen
ions (H
+) and negative oxygen ions (O
2-) by the plasma ion. The substances attached with water around the ions are adhered
on the surface of viruses and bacteria and converted into OH radicals with extremely
strong oxidizing power, thereby removing hydrogen (H) from the protein on the surface
of viruses and bacteria, and thus decomposing (oxidizing) the protein, so as to filter
the introduced air pollution and achieve the effects of filtering and purifying.
