Founded in 1989, COWAY Brand is a well-known brand of environmental home appliances in Korea. It has won the Korea Industrial Brand Influence Award and is a leading technology company in the Korean home appliance industry. COWAY has the world's largest R&D center for water quality and air quality as well as the Institute of Environmental Science and Technology. It has a leading market position in the world of intelligent environmental electrical appliances such as water purifiers, air purifiers, softeners, and smart toilets. COWAY's air purifier products have been introduced to the Chinese market since 2012, bringing more premium choices to Chinese consumers who are haunted by haze.
Today haze survival lab will COWAY's flagship model AP-3008FH air purifier into comprehensive evaluation. The empty net is sold at COWAY Yi Xun for 7380 yuan, then this empty net quality is still on the high price after the price?
The COWAY AP-3008FH has a three-dimensional dimension of 600×920×410mm and a weight (net weight) of 25Kg. It can be said that it is the largest household in the market that is vacant. Therefore, using the word “big thing†to describe COWAY AP-3008FH is really appropriate. In order to reduce the cumbersomeness caused by the huge body, the designer adds a corrugated design to the front panel, uses silver trim and curved design around the body, and with exquisite workmanship, makes the body of the COWAY AP-3008FH stand out. .
With the odor sensor located on the top of the fuselage and the air sensor on the right side of the fuselage, the COWAY AP-3008FH can accurately detect the indoor air quality. In the automatic mode, the wind speed is automatically adjusted and the air quality is determined by the pollution degree indicator on the top of the fuselage. Reflected to users, it is clear that this empty net follows the consistent intelligent design concept of Japanese and Korean products.
In order to facilitate the user to transport the COWAY AP-3008FH weighing 25Kg, the manufacturer installed a carrying handle on both sides of the airframe.
A pair of moving wheels is set behind the bottom of the fuselage.
The actual experience of the manual shows that the lower handle and rear moving wheel on the rear side of the fuselage just form a pair of laborious levers. The user must bend down to work hard to lift and move the COWAY AP-3008FH . If the body handle is set higher on both sides of the front fuselage, the COWAY AP-3008FH will be easier to transport.
The power line length of the COWAY AP-3008FH is 1.7 meters, which can meet the needs of most users. However, the COWAY AP-3008FH did not provide a storage slot for the power cord on a large body, which is a little regrettable.
The empty net integrates the display area and the operating area on the top of the fuselage. The user can choose to manually control or automatically run the COWAY AP-3008FH through the five buttons: air volume, mode, stereo loop, cartridge replacement, and run / stop . The button feels comfortable and the operation method is also easy to understand. The user can learn how to operate the COWAY AP-3008FH by following the instructions .
light pollution
The light of the COWAY AP-3008FH , the three-dimensional circulation of the model, the three-dimensional circulation, and the replacement of the light of the filter are yellow; the pollution degree indicator adopts the blue, lilac, deep purple and red four-color light conversion to represent the high quality of the air quality. , clean, ordinary, and polluted four states. When the COWAY AP-3008FH is in the AUTO mode and the power-saving mode, the ambient light level is sensed by the photometric sensor on the top of the camera body, and it is automatically switched to sleep mode at night to turn off the light in the display area.
COWAY AP-3008FH has two operation modes: manual operation and automatic mode. In the manual operation mode, there are five air flow modes: "1st, 2nd, 3rd, 4th, and turbine". In the automatic mode, there are "automatic, deodorizing, Mute, A3 power-saving mode "four kinds of air volume mode. Because the air volume in the automatic, deodorizing, and A3 power-saving modes will change with the current air quality, the manual does not measure the wind speed in these three modes.
Remark: In this machine, we have a large error in the air flow measurement method. The actual air flow rate may be much lower than the measured data. Therefore, the air volume data of this machine can only be used as a reference.
Calculating the wind speed mode air volume air volume level mode 2.46m / s 8.191m³ / min 491.46 m³ / h air volume level 2 mode 3.01m / s 10.02m³ / min 601.2 m³ / h wind mode three 3.67m / s 12.22m³ / min 733.2 m3/h Class 4 air volume mode 4.42 m/s 14.71 m3/min 882.6 m3/h Turbine air volume mode 5.36 m/s 17.84 m3/min 1070.4 m3/h Silent mode 2.20 m/s 7.326 m3/min 439.56 m3/hThe maximum air output of most small purifiers on the market is exceeded in the Class 1 air volume model. The level 2 air volume model is basically close to the maximum air output of most large and medium-sized purifiers on the market. The air volume at level 3 basically exceeds the maximum air output of most large-scale purifiers on the market. In the 4 -class air volume mode, it is equivalent to 5 times in a 63- square-meter room with a standard floor height of 2.8 meters in 1 hour . In wind turbine mode, the wind speed is 5.36m/s and the air volume is 17.84m3/min . The calculation of air volume per hour is 1070.4 m3/h , which is slightly higher than the officially released 1008 m3/h air volume laboratory data. In silent mode, COWAY AP-3008FH is basically equivalent to a 31.3-square-meter living room with a height of 2.8 meters at the minimum wind speed. Â
This clean, high wind speed allows it to have a large CADR value (clean air output, the greater the value the higher the purification performance), according to the certification data of the AHAM (American Household Electrical Appliance Manufacturers Association), COWAY AP-3008FH With a CADR value of over 450, this is the highest value in the market for home sales. What is the advantage of this super-high CADR value to this empty net? Please pay attention to the following purification capacity testing session.
After the manual test, the noise of the COWAY AP-3008FH under the manual operation of the five types of air mode and the silent mode of the automatic mode is as follows (test results include laboratory ambient noise, the test does not include automatic, deodorant, A3 power saving three mode).
According to the test results, when the indoor environment was created for 32 days, the noise emitted by the COWAY AP-3008FH Silent Mode, Level 1 Airflow Mode, and Level 2 Airflow Modes can meet the requirements of the bedroom specified in GB 50118-2010 Domestic Building Sound Insulation Design Specification. The allowable noise between ≤45 dB and the allowable noise at night is ≤37 dB. In the case of such a huge amount of outflow, this empty and clean noise management performance can be described as excellent. It should be noted that if the state of the fuselage is not stable and the four legs are not evenly distributed, the COWAY AP-3008FH will cause significant resonance and vibration when operating at the level 3 or above. Next, please measure the energy consumption of COWAY AP-3008FH together with the manual (the test does not include the three modes of automatic, deodorization, A3 power saving):
The final result of the test is as follows:
According to COWAY AP-3008FH continuous operation under the "quiet" for 24 hours, the power consumption of the empty net day is 0.34 kWh. According to the maximum four speeds in the automatic mode, the power consumption range is 0.34-1.56 degrees. According to the official introduction, the 24-hour power consumption is about 0.9 kWh under the comprehensive condition.
After introducing the basic situation, the COWAY AP-3008FH performance test can finally be started. First of all, the manual is going to be an indoor smoke test. The manual lighted several cigarettes in a 12 m2 (29 m3) closed laboratory. Â After about 500 ug/m2 after full combustion, turn on the purifier to record the PM2.5 value of the room, and then stop to the lowest value and record the time.
From the experiment we can see that the COWAY AP-3008FH reduced the concentration of PM2.5 in the laboratory air from about 500 ug/m3 to 25 ug/m3 in 5 minutes of operation , and the filtration performance is extremely strong, which confirms this High machine CADR value. COWAY AP-3008FH powerful purification capacity sufficient to ensure that indoor air quality can be achieved when running our country issued in 2012 "ambient air quality standards" provisions of GB 3095-2012 indoor air PM2.5 daily average concentration does not exceed 35 ug /m3 requirements.
After completing the smoke test, COWAY AP-3008FH drilled into the sealed box and started its own sealed box test.
The instructor of the manual ignited 1g of red phosphorus in a sealed box . The red phosphorus burned for 5 minutes to produce a large amount of smoke and then went out. At this time, the experimenter opened COWAY AP-3008FH to the turbine air volume mode and recorded the PM2.5 concentration in the sealed box after 20 minutes of operation. value.
After 20 minutes, the laboratory technician showed that the PM2.5 concentration in the sealed box was 0 ug/m3 through the TSI8530 desktop dust meter, and COWAY AP-3008FH still maintained an excellent level of net smoke in the sealed box.
Excessive formaldehyde content in home-improvement building materials is a lingering haze in the minds of the Chinese people. Purchasing an air purifier to remove formaldehyde from the air in the home has gradually become a popular trend. Now, readers are invited to carry out the formaldehyde removal test of COWAY AP-3008FH together with the manual. Â
First, the formaldehyde content in the air in the laboratory was raised to 0.52 mg/m3 through a special formaldehyde vaporizer , and COWAY AP-3008FH was turned on to the turbine air volume mode to perform the formaldehyde test.
Within the 90 minutes defined by the experiment , the formaldehyde content in the laboratory air was significantly reduced by the COWAY AP-3008FH . Although there is a certain distance from the standard of formaldehyde in the indoor air of GB/T 16127-1995 “Hygiene Standards for Formaldehyde in Indoor Airâ€, which is the maximum allowable concentration of 0.08mg/m3 for formaldehyde in the living room , it has been tested as a home air cleaner. The household with the strongest ability to remove formaldehyde is empty.
COWAY AP-3008FH adopts a mature fan + strainer filter structure, so it will not be accompanied by any ozone during operation, and easily passed the manual ozone emission test.
The user needs to unscrew the safety lock under the front panel of COWAY AP-3008FH with a “ 1 †screwdriver or coin to open the empty front panel upwards. This ensures one-step safety but also ensures safety for children. Sex to prevent accidental production.
Behind the front panel is a large black pre-filter, the main role of which is to organize large suspended particles in the air, such as human and animal hair. The filter is to avoid the replacement of the filter, only regular cleaning.
After the pre-filter is a non-woven filter of non-woven material, it is pasted on the custom filter surface, it is more difficult to find, mainly after the pre-filter to further block the air in the larger suspended particles Role, while protecting the next level of filter. The filter needs to be replaced every 2 months.
Followed by a custom filter, the user can freely select the grease filter, antimicrobial filter or ozone filter when ordering COWAY AP-3008FH . Products sold in China are equipped with a degreasing filter by default. The function of the grease filter is to catch oily oil in the air. Replace it every 4 months and the machine has a filter replacement prompt. Â
The last is a second filter box with integrated deodorization filter and HEPA filter. The filter box is fixed on the body with two screws. The user needs a screwdriver to remove it from the COWAY AP-3008FH body. .
In the second filter box, two live deodorizing filters and two HEPA filters are respectively integrated. The deodorizing filter is made of coconut shell activated carbon and its main function is to remove toxic substances such as formaldehyde, TVOC, etc. from the air. Through manual testing, it was confirmed that the COWAY AP-3008FH has excellent deodorizing filter performance. The deodorizing filter needs to be replaced every 12 months according to the machine's instructions.
The last is two HEPA filters. The main function is to filter the PM2.5 particles in the air . Although they are not labeled, they should be considered higher in terms of filtration efficiency. COWAY's proprietary anti-virus filter surface green coating is an anti-viral substance extracted from Japanese Ginkgo biloba and lacquer trees . It is said to have a considerable inhibitory effect against pandemic viruses including the bird flu ( H1N1 ) virus. The HEPA filter is also replaced every 12 months according to the machine's instructions .
It is also worth mentioning that the filter sealing performance of COWAY AP-3008FH is very prominent. The sealability of the purifier is decisive for the product. If there is a gap between the purifier filter and the machine, the dust absorbed by the turbine will accumulate on the motor and the fan. If the filter is not cleaned in time, the purifier itself will become the indoor air. Contaminated pollution sources, usually the technical gap between high-end professional purifiers and general purifiers are here.
Consumables cost COWAY AP-3008FH non-woven filter, grease filter, deodorant filter and HEPA filter need to be replaced regularly, these four filters in the COWAY official Tmall , respectively, the price of 90 yuan, 190 yuan, 380 yuan and 450 yuan. Calculating the cost of replacing all filters of COWAY AP-3008FH once is RMB 1,110. According to the calculation of filter life given by COWAY, the daily filter cost of COWAY AP-3008FH is about RMB 3.77. In addition, users can also purchase customized ozone removal filters or anti-microbial filters in custom filters through COWAY's official website to select different efficiency filter screens for different environments to replace the original oil screen filter to enhance the clean air Special pollution purification capacity. For example, if an office has a photocopier and other electrical equipment that produces ozone, the addition of an ozone filter is a good choice. General commentsAlthough the COWAY AP-3008FH has many problems such as a large airframe, inconvenient handling, and complicated dismantling and maintenance, it is not a big deal. Thanks to the huge size of the market, COWAY AP-3008FH can accommodate larger sizes and more combinations of filters. The net has excellent air purification capability; in addition, the strong wind volume and high CADR value of COWAY AP-3008FH can meet the needs of the indoor area of ​​50-100m2, which is very suitable for commercial customers or customers with larger homes. Customizable filters can also make this empty net strong on the purification of specific pollutants, although the price of 7380 yuan is not cheap, but taking into account the effectiveness of a few top Taiwan and imported from Korea Identity, COWAY AP-3008FH is still a wise choice.
