In recent years, with the improvement of people's health awareness, air purifiers have become a standard configuration for many households. As a key component of air purifiers, what is the quality of the filter screen?
Recently, Hebei Environmental Protection Product Quality Supervision and Inspection Research Institute (hereinafter referred to as "Hebei Environmental Protection Institute") conducted an investigation on the quality of adaptive filters for household air purifiers, and the results are worrying. It seems that air purifiers alone cannot give people peace of mind. It is necessary to choose a high-quality filter to truly ensure air quality.
There are various missing annotations in national standards
The reporter logged into a large e-commerce website and saw thousands of air purifier filter products, with various models and a dazzling array of features. All product functions are labeled as "formaldehyde removal, smoke and dust removal, odor removal, humidification and purification", but the parameter labels are varied and the prices range from tens to thousands of yuan.
The design and service life of air purifiers can reach several years, but the filtering performance of the filter decreases continuously with the accumulation of pollutants during use. When it reaches saturation, it will not be able to purify. Its service life is often only six months to one year, and the worse the use environment, the shorter the service life. Frequent replacement of the filter is an inevitable problem faced by air purifiers during use.
Whether the air purifier can still achieve the purification effect at the factory after replacing the filter has not been studied and proven. At the same time, there are various types of filters in the market, including original factory specific filters and adaptive filters produced by other manufacturers. Whether these filters can meet the design requirements of air purifiers still lacks targeted research, which is also the main reason why consumers face confusion when choosing filters.
