[PConline Professional Review] After entering the winter, hazy weather is on schedule. Compared with previous years, this year's representative smog weather completely reminded everyone, Shenyang, Beijing, Shanghai air quality bursts of watch, smog seems to swept the north and south over the heating season overnight, air purifier broken When goods and masks are out of stock and armed, they are more protective of the health of their families. Not long ago, LIFAair LA500 air purifier has excellent performance on the four core indicators of the new national standard, among which the CCM (cumulative purification amount) and purification energy efficiency have surpassed the new national standard by a wide margin, and have attracted widespread attention from the industry and consumers. Therefore, the PConline evaluation room for everyone to evaluate the LIFAair LA500 air purifier, let us look at whether it is strength and fame?
In addition to its excellent purification capabilities, the LA500 also has innovations in appearance design, operation methods, and filter media. Through independent intelligent monitoring and controller, a variety of high-precision sensors are built in to accurately measure PM2.5, formaldehyde, carbon dioxide, and other parameters. Depending on the indoor pollution situation, the appropriate mode is selected to enable the purifier-related functions. The high degree of intelligence makes the LA500 an empty net robot. Next, we will interpret the product in terms of product appearance, filter media, operation methods, actual purification effects, and energy consumption.
Appearance and details
A good air purifier must not only have excellent purifying power, but a stylish design can also add a lot to the product. LIFAair LA500 air purifier is a subversion of the traditional design. Its cylindrical design occupies only 30 cm in diameter and 0.07 square meters of space. It is especially suitable for compact home environment and more space-saving. All-metal body supplemented by white piano paint technology, the whole machine without any physical buttons, the Nordic simple style to the extreme. Do not seriously understand that it is also an ornament in the home, in fact, it also plays a major role in purifying the air.
People who saw the LA500 for the first time will never think of it as an air purifier. It looks more like an aircraft engine in appearance. This is also the appearance of the LA500 purifier that has changed the design style of traditional purifiers. It is a white body. The overall shape is a cylinder with a diameter of 300mmx800mm and a body weight of about 15kg. With a CADR value of up to 450 m3/h, the LA500 is suitable for indoor spaces of 31-54 square meters. The space occupied is only a 0.07 square meter area with a diameter of 30 centimeters.
Different from the common air purifier products on the market, LIFAair LA500 uses a unique touch wind speed adjustment method. By gently touching the arc on the top of the body with the hand, the wind speed is increased (weakened) by the clockwise (counter) hour, and the fan can be easily adjusted. Speed, infinitely variable air volume adjustment mode can be accurate to the user's most desired position, personalized. The way to adjust the wind speed of this product is only the touch type, but the touch type is prone to malfunction. It is recommended that manufacturers add some protection designs in the touch reaction area.
The round hole design of the lower part of the LIFAair LA500 air purifier facilitates convection with the air, allowing it to purify the air in all directions instead of a single direction. The small size of the round hole will not suck in the small items in the home. The design is humane and beautiful.
As in the video presentation, swiping the touch area clockwise is to increase the wind speed, and sliding the touch area counterclockwise is to reduce the wind speed, which is easy to operate and avoids the trouble of often finding the remote controller.
One of the features of the LIFAair LA500 is the separation of the purifier from the monitor and its various functions. The photos and simple descriptions of the accessories are attached below. The simple placement of the accessories box makes the buyer feel comfortable.
Air purifier filter system dismantling
The filter is an integral part of the entire air purifier. To ensure the purifying effect, the LA500 uses two sets of filter media arranged one above the other, each set of filter media including the primary filter acting as the carrier of the activated carbon drum and the activated carbon in the middle. Particles and inner HEPA filter cartridges with a dense cylindrical structure ensure that every strand of air is filtered through the screen. In order to ensure safety, the product needs to be turned over in the event of a power failure. The chassis panel is rotated counterclockwise to open the chassis, and the activated carbon cartridge and the HEPA filter cartridge are removed one by one. (The first time you need to take out the packaging bag of the activated carbon cartridge, the product can work properly)
(To ensure the transportation process and ensure the effectiveness of the filter, it will be sealed with adhesive tape before the first use)
Each active charcoal barrel is filled with 1.75kg of high-quality LIFAair specially formulated acid-proof activated carbon, and the total weight of 3.5kg of acid-proof activated charcoal can filter 137m3/h of formaldehyde. The inner HEPA filter cartridge has a filter rating of H12. It is produced by APOLLO, a Japanese professional filter cartridge supplier. The CADR of particulate matter is up to 450m3/h, and the particle removal rate of PM2.5 is up to 99.99% in 30 minutes. Suitable for 32 - 55 square meters of interior space.
The design of the activated carbon cartridge on the outside of the HEPA cartridge can effectively eliminate the secondary pollution of the carbon powder. The data shows that the deployment area of ​​the two filter cartridges is 4.6m2, which means that under the same air flow rate, the wind speed through the filter element will be reduced, so that the high-quality HEPA filter material can more easily capture dust particles, while saving energy and at the same time Extend filter life. The HEPA filter cartridge is cleverly designed to leave plenty of space for full contact with the air to achieve air purification.
Split monitoring
Download the APP on the mobile phone (two-dimensional code in the manual), open the APP connection monitor, click on the monitor to connect the network, you can successfully add the device in the mobile phone APP.
The LIFAair LA500 monitors and purifiers use a split-type design. In addition to being able to ensure the simplicity of the main body, the current indoor air quality can be viewed at any time through the monitor and the air purifier can be operated and controlled directly on the monitor.
LIFAair LA500 has built-in a variety of high-precision sensors that can accurately measure indoor air PM2.5, formaldehyde, carbon dioxide concentration and temperature and humidity and other parameters, and according to the indoor air pollution situation independently choose the appropriate mode to start the purifier-related functions. Different from most products on the market, users need to set their own programs before they can start working. The LA500 is more intelligent and will undoubtedly provide users with more convenience in daily use.
Purification capacity test
Secondhand smoke is one of the most common sources of air pollution in most households. It is a combination of dust, odors, and air pollutants such as PM2.5. In order to test the purification effect of LIFAair LA500 on common air pollutants, we closed the doors and windows in an ordinary home environment with an area of ​​about 25 square meters. After igniting some cigarettes, the smoke was fully diffused and the current indoor air was measured by the CEM air quality detector. PM2.5 was 1356 (μg/m3) and PM10 was 3896 (μg/m3). We use the tester to test the PM2.5 index in the air, detect PM2.5 in the room every 10 minutes, and measure the time effect of this air purifier at different times.
After the four cigarettes used in the experiment were completely burned, the indoor air pollution index was measured with an air quality tester. It was found that PM2.5 was as high as 5100, which was a very heavy level of pollution.
Turn on the air purifier for testing
Open the air purifier and adjust the wind speed to the maximum gear position. At this time, the air outlet at the top of the fuselage starts to send air quickly to quickly purify the indoor air. The light of the product at work is white. Ten minutes later, we again used the air quality tester to perform the test, and also used the feedback information of the monitor on the mobile phone APP to detect it. The air quality indicator on the APP is red.
Twenty minutes later, we conducted the test. The air quality tester has a detection value of 413, and the mobile APP air quality indicator light is orange, but it is much better than the initial situation.
Thirty minutes later, the Air Quality Tester detected a value of 142. The air quality indicator of the mobile phone APP was already green, which shows how amazing the speed and efficiency of the product's air purification are.
Forty minutes later, the air quality tester has detected a value of 79. It has returned to normal. The air quality indicator light of the mobile phone APP is already green. At this time, the air quality is even better than when no cigarette was initially burned.
Summary: In the purification capacity test, the product's working efficiency made the author's difference. In only 40 minutes, the extremely polluted 25 square meter room was cleaned up. The purging speed is almost the same in all stages and will not slow down significantly. In this test, the product passed the perfect score.
Airflow and noise tests
Air volume test
Next, we will test the wind speed. Since the LIFAair LA5000 uses a continuously variable speed fan, we use the lowest gear and the highest gear respectively. The wind speed is an important factor in determining the CADR of the purifier. CADR is one of the indicators of decontamination ability. It can quickly circulate indoor air and output clean air. Do not underestimate the location of the tuyere, not only looks beautiful, its 36 fins are inclined at 45 degrees so that the fresh air evenly spread throughout the room.
Noise test
The noise test of the air purifier is very important. When used at night, it will directly affect the user's sleep. Therefore, a good air purifier is less efficient and less loud. Due to the use of an infinitely variable speed fan, we next select the volume of the volume emitted in the lowest and highest 45dB environments.
Summary: The mute product has almost no sound, but it also purifies the air. It feels very good. The performance of low-middle and high-grade sound is excellent, but the sound is slightly larger at the injection position and reaches 66dB, which will have a certain impact on sensitive people. From the test, the LIFAair LA500 is powerful and powerful in wind transmission, which can accelerate the purpose of purifying the air. It is a first-class quality in its class.
Power test and summary
Air purifiers must be used for a long time, so the power used is particularly concerned. This time we chose the lowest and highest grades for testing. Test them separately to see how much power they are working on.
Summary: In the power test, the power consumption of LIFAair LA500 is relatively low, from the 0.4W of the mute file to the 52W of the highest grade, all of which are excellent grades in the similar products. Driving a high-end car for a long period of time will not consume a lot of electricity. What's more, it only needs to be adjusted to the middle and low levels.
The full text concludes: The LIFAair LA500 air purifier has a unique appearance and uses a cylindrical appearance, which does not occupy too much space. Thoughtful on the filtration system, but the replacement of filter equipment is troublesome, HEPA filter cartridges must be purchased after use to continue to use. In addition to this small flaw, the LIFAair LA500 air purifier has outstanding purification ability. It can perfectly complete the assessment task in 40 minutes. It is also excellent in terms of noise and power consumption, low power consumption and low noise, and is suitable for home use. Finally, the separation of the purifier and monitor makes it easier for the user to control and is a major highlight of the product.
