The CADR value is the main indicator for the evaluation of air purification performance by an international authority, and is an abbreviation for (Clean Air Delivery Rate).
The performance of the air cleaner is mainly determined by the clean air output ratio (CADR value). The larger the clean air output ratio, the higher the purification efficiency of the purifier. To make the indoor air quality reach a certain clean standard, the air purifier has two necessary hard indexes: 1. The indoor air must reach a certain number of air changes (international 5 times); 2. The air purifier is once cleaned The efficiency must be high. If indoor sources of pollution continue to occur, these two hard indicators of air purifiers can keep indoor pollutants at a lower concentration.

In the third layer of custom filter, Coway AP-1005AH can customize different filters according to the needs of users to achieve different functions.
For an air purifier, the cost of consumables is also the focus of the user. After all, the cost of these things is relatively high. Users want a clearer guide to let them know when they need to replace consumables. how many. In Coway's Taobao flagship store, this information is very clear, this is commendable.
On this Coway AP-1005AH, there is also a children's model for children. In this mode, the air purifier will automatically run in a weak wind to prevent children from catching cold.
Coway's AP-1005AH air purifier brings users more advanced technology and the need for efficient air purification. Is this 5-layer filtration system really effective in removing air pollutants? What is its ability to remove formaldehyde and the effect of removing smoke? We will use pictures and videos to present to netizens.
â—Coway AP-1005AH Appearance and Details
The front of the Coway AP-1005AH is close to a square, and its volume is relatively small in an air purifier. However, in official data, the maximum purification area of ​​such a “small machine†actually reached 90 square meters, which is a bit unbelievable. In the purification test, we can know the answer.
The functional area of ​​the Coway AP-1005AH is centered on the upper right corner of the front of the fuselage, but everything still takes a simple route, and there are not many things, even the LCD screen showing the working status is not.
One of the most important parts of the air purifier, the pollution sensor is also designed on the right side of the fuselage. This instrument controls the working status of the purifier. For example, when the purifier is set in the automatic mode, the machine must pass it. The air volume is set, so the manufacturer recommends that we clean it once in two months.
Summary: Through the appreciation of the appearance details of the Coway AP-1005AH, we found that in the design of the body, the manufacturer is also the principle of simple supremacy, and many consumers may feel puzzled: This is a more than 4000 pieces of air purifier Why is it so simple to design? In fact, every part needs money. In other parts, it is simpler. It uses money on the edge and spends most of the purifying function on the purifier. Isn't this good?

â—Coway AP-1005AH purification capacity test
Ordinary home indoor purification effect is the key to determine the quality of the air purifier, this time we select 40 square simulated home environment for testing. After lighting up five cigarettes in a closed room to make it fully burned, second-hand smoke was used to fill the room. Using the tester to test the PM2.5 index in the air, PM2.5 was measured every 10 minutes to check the time effect of this air purifier at different times.
Test Environment: 40 square home environment
After the cigarette burned, the odor diffused into the room. Using an air quality tester, the indoor air pollution index found that PM2.5 was as high as 1024, which was a very heavy level of pollution.
Turn on the air purifier for testing
Turn on the air purifier and adjust the wind speed to automatic mode. After entering the office every 10 minutes, the air quality has changed. The use of a tester to test the concentration of PM2.5 has been found to have reached a moderate level of pollution.
When using the detector test after opening to 20 minutes, the air quality was noticeably improved, and it can be seen that the air quality indicator also turned pale blue to prove that the air quality began to improve. The air quality has dropped back to excellent and good.
The 30-minute test time has come. Once again entering the room and smelling the smell in the air, it can be seen that the air quality has obviously improved. The indicator light also turns blue and no turbidity appears. The inspection data also found that it has reached an excellent level.
Summary: In this test of purifying capacity, it was found that the original air pollution index was as high as 1024 as a dangerous and serious pollution level. However, after 10 minutes of filtration, it was found that the air purifier had cleaned the room to a medium level of 447. By 20 minutes, entering the room was a sign that it was getting better. Only 248 were excellent and had a good tipping point. When 30 minutes were completed, they entered the test space and found that there was no smoke. Through the tester, it was found that the PM2.5 value reached 152 and reached the state-proven level of good grade, proving that the air purifier has an efficient purification capability, and this is just the data obtained in the case of turning on the automatic mode, I believe if it is always on Stronger mode, the effect will be better, and the purification time will be shorter.
â—In addition to smoke test
The smoke makes the human body feel uncomfortable, and sometimes the smell of cooking smoke is transmitted from the kitchen to cause smog. The human respiratory tract is quite sensitive and can easily be picked up. At the same time, mosquito repellent tablets will produce a large amount of formaldehyde harmful substances. This time we also selected a 40-square-foot office environment. The doors and windows are closed. Specially-made mosquito repellent tablets are ignited in a closed room. The smoke produced after ignition is accompanied by a pungent odor. Use a tester to measure the air pollution index and test indoor air pollution values ​​every 10 minutes. Check the actual purification of this air purifier at different times.
Test environment video display:
Turn on the purifier and the formaldehyde tester finds the changes:
It can be seen from the video that the smoke emitted by the mosquito repellent film is quite large, and the entire environment is covered by smoke. Can also smell a strong pungent odor. The tester can see that the indoor air pollution index has reached a peak value of 3,983 above.
Turn on air purifier detection
The air purifier is turned on, and the purification capacity is also maximized. After 10 minutes of decontamination, the PM2.5 concentration in the air has dropped to 1704. However, smoke and irritating odors can also be found. Formaldehyde tester can also be found to reduce to 0.25mg/m3.
Twenty minutes after the start, the concentration of PM2.5 had been reduced to a moderate level, and the formaldehyde removal effect was 0.21 mg/m3.
When it was turned on for 60 minutes, it was found that PM2.5 had already landed and the smoke had disappeared. Formaldehyde test data is 0.15 mg/m3.
Summary: After 60 minutes of re-entry into the home environment, it has been found that no irritating odors have been smelled and the air is filtered again. From the tester, the smoke and irritating odor produced by the PM2.5 value of the mosquito-repellent incense sheet shrouded the entire room. After 60 minutes of purification, there was a marked improvement, and the formaldehyde test achieved an excellent grade in about 60 minutes.

Test Data
Next, we will test the air volume noise, power consumption, and noise. We will use five levels of air flow for testing, and the wind speed will determine the CADR important factors of the purifier. It has become one of the indicators of purification ability.
T gear power
4-speed power
3 gear power
2 gear power
1 gear power
Summary: From the power test, it is found that the power from the first gear mode to the fourth gear mode is not much different. The T gear is the strongest gear and therefore has a difference from the previous gear. Relatively speaking, the power is not high in the high-speed mode, and at the same time, efficient and rapid purification capability is obtained. After the purification effect is achieved, the user can select a lower gear according to his/her own requirements, which can keep the air clean and save power.
Summary: Coway AP-1005AH in the appearance of compact while maintaining an excellent purification effect, and its noise value and wind speed to the author left a deep impression on this evaluation point of view, South Korea's first environmental home appliance brand really The reputation of the company was well-deserved. Although it may be due to market tactics that cause the Coway brand to be a bit "low-key," its strength is still worthy of consumers' attention.
