Which brand of air purifier works well? In order to find a high-quality air purifier product, the whole team decided to evaluate a number of star products on the market to see which one is the real cost-effective air purifier.
In order to find a suitable comparison among many brands of air purifiers, we decided to select the following 5 air purifier products for comparison on a large domestic platform, and the specific product information is as follows:
In this test, we will focus on 4 areas of results:
Test 1:Is the formaldehyde cleaning level of the household air purifier enough?
Since formaldehyde volatilization is the most likely problem in home decoration, we must first evaluate the purification ability of the air purifier.
[Test Objectives and Evaluation Criteria].
In order to be as objective and fair as possible, under the guidance of professionals, we tested by simulating the general family living environment, and these 5 products all met the corresponding requirements.
Airflow Coverage Capacity:Is the air circulation in my house qualified?
The air volume coverage of the air purifier is related to whether there will be a dead spot area, so in order to understand the situation more intuitively, we plan to start the evaluation with the lowest wind speed.

In this round of rankings, GA and Philips are among the best air purifiers.
FormaldehydeProcessingCapabilities:Treat the indoor environment as if it were a real home scenario
Regarding the problem of formaldehyde, in order to be as realistic as possible, we chose an indoor environment of 50m to simulate the layout planning of an ordinary home.
Subsequently, we also set up monitoring points in different areas and used professional equipment to detect the proportion of foreign objects in the indoor air. After some testing, it was learned that the formaldehyde purification power test results of different brands of air purifiers are as follows:
Conclusion 1:All 5 products are qualified
Which brand of air purifier works well? In this test, 5 products have met the corresponding domestic requirements (0.08 below), among which the fastest to complete the test are GA air purifiers and Shulox, which only took 12 minutes to meet the corresponding needs, and even faster than other similar brands.
Conclusion 2:There is a residual space for purification
Although the overall performance of the 5 products is good, there are still deficiencies in some details, such as Honeywell and Philips have some purification blind spots, which can easily lead to excessive indoor formaldehyde residue content.
For verificationThe long-term working efficiency of different brands of air purifiersWe decided to let them be turned on for 60 days before coming back to the test. Which brand of air purifier works well? Among the 5 products, only the levels of GA and 352 are relatively good after long-term use, while the other three have shown varying degrees of decline.
Because the release of formaldehyde is continuous and slow, it is necessary to keep the air purifier normally open in order to effectively remove formaldehyde, so it is necessary to choose a product with the best ability to remove formaldehyde after long-term use。But many consumers don't understand this, so it's easy to be confused by sellers with some words. "The air purifier is not absolutely good if the value is high, but it also needs to look at the purification staying power".
The purification levels of different brands of air purifiers after 60 days are as follows:
Test 2:pm2.5. Detection sensitivity
pm2.5 Needless to say, in order to look at the PM2 of different air purifiers5. Detection sensitivity, we decided to test them separately in a confined space. The actual results showed that the highest detection sensitivity was GA and Schulox.
Test 3:Disinfection and sterilizationEffects
How to choose if there are elderly people and children at home
In addition to the cleaning ability, sterilization is also a very important part, these products are relatively big brands of air purifiers at home and abroad, so they all use different specific sterilization technologies, the specific content is as follows:
In order to display the results more intuitively, we also specially selected nutrient agar plates for display.
Comparison before and after bacterial culture.
[Visual Strawberry Test].
Considering that many netizens may have no idea about this result, we decided to use strawberries for a more intuitive demonstration, so that everyone can further deepen their understanding.
Also edible: Shule's, GA
Which brand of air purifier works well? After two days of testing, it was found that the strawberries of the GA group and the Schulox group were basically no problem and were still in an edible state. But the other three groups had mildew and rot.
Mildew: Philips, Honeywell, 352
The mildew of these three groups is different, some have begun to rot, some have black and white hairs, and the first group to have mildew is Philips.
Strawberry status before testing:
Strawberry state after 2 days:
From this group can draw a conclusion:Not all air purifiers can truly disinfect and sterilize
[Total amount of bacteria].
According to the monitoring data of professional equipment, only two groups of strawberries, GA and Shule's, can still maintain their condition.
Test 4: Cost of use
With an air purifier, which filter is more cost-effective
Finally, we also considered a cost of use, so we specifically learned about the life and quality of the filter from a certain platform. Judging from the results, GA only costs 1 yuan a day, and Schulox is twice as high as GA.
Final summary: 5 major brand evaluation scores
Conclusion:
Which brand of air purifier works well? Overall, after two months, we found that the really cost-effective air purifier is still the GA air purifier, although the GA air purifier is not the most expensive of these brands, but its performance is beyond expectations, and it is enough for most families.
