Multi-day fog, bonfire, air purifier, purification function can not be “myth”
Is the air purifier really useful?
According to the publicity of the business, in addition to removing PM2.5, the best quiet air purifier can effectively remove harmful substances such as formaldehyde, and the removal efficiency is very high, reaching 99%. However, because the purification effect is difficult to detect, many consumers buy more psychological comfort when purchasing.
“The best quiet air purifier HEPA has a certain purifying effect on air impurities, but it does not have the ability to completely purify, because it can’t circulate the air in the whole room, such as two rooms and one hall, and can only circulate and purify the air in one space.” Wu Changzhou, who has been engaged in environmental monitoring for more than a decade, said that air purifiers can only make local airflow, so they can only be partially purified.
In the purifier of the air purifier, the air purifier can solve the particles of 0.25 micron and above in the air, but it can not solve the decoration pollutants in the air. “I want to use air purifiers to eliminate harmful substances such as formaldehyde and benzene. This is a mythical function of purifiers.” Wu Changzhu said that if citizens feel that there is a smell in the new house, they can conduct professional testing first, then carry out targeted treatment and cut. Do not rely solely on an air purifier.
At present, the market for air purifiers is getting hotter, the industry is chaotic, and the quality of products is mixed, which affects consumers’ perception of air purifiers to some extent, but this situation will be eased next year. It is understood that a few days ago, the National Standards Committee issued a new revised “Air Purifier” national standard, the new standard will be officially implemented on March 1 next year. By then, it will effectively change the chaotic labeling phenomenon in the air purifier market, and it will also enable consumers to make evidence when they purchase.
