Is the negative ion air purifier useful? To really solve this problem, you have to look at the purification effect.

Traditional filter-type air purifiers are difficult to filter for some fine dust, especially dust of less than 3 microns, and cannot effectively eliminate the PM2.5 hazard. China Quality Certification Center United Nations Indoor Environment and Indoor Environmental Product Quality Supervision and Inspection Center officially issued the "Air Purifier Environmental Certification Rules", some experts pointed out that the current filter-type air purifier on the market does not play a role in PM2.5 .

According to the research of many experts in the field of air environmental protection in the United Nations, ecological-grade negative ions (small particle size negative ions) can actively capture small particles of dust, causing them to coagulate and precipitate, effectively removing dust of 2.5 micron (PM2.5) and below. Even 1 micron particles, thus reducing the harm of PM2.5 to human health, the purification effect of ecological-grade negative ions on air is caused by the combination of negative ions with positively charged particles such as bacteria, dust and smoke in the air. The ball landed to eliminate the PM2.5 hazard. Experiments have shown that the smaller the diameter of the fly ash, the easier it is to be precipitated by negative ions.

Since the traditional filter-type air purifier mainly intercepts pollutants through the filter screen, this requires the consumer to periodically replace the filter screen, and the subsequent secondary consumption becomes a problem for everyone due to the high input cost of the filter screen.
