Question:
Can air purifier remove formaldehyde?
Reply:
Air purifiers are now well known. In addition to the removal of PM2.5, can it be used to remove formaldehyde? In fact, most air purifiers currently on the market have the ability to remove formaldehyde. This is mainly due to the filter. Activated carbon in the composition. Activated carbon is recognized as a 'universal adsorbent', its fine internal pores can adsorb many substances including formaldehyde.
Judging the strength of a purifier in addition to formaldehyde capacity mainly depends on its formaldehyde CADR value. After the introduction of the new national standard, this indicator can be easily found on the product page. Some CADR values for formaldehyde are 100m3/h, and some are 400m3/h. The larger the value, the stronger the ability to remove formaldehyde, which is related to the content of activated carbon in the filter. The greater the content of activated carbon, the better the ability to adsorb formaldehyde.
Although air purifiers have the ability to remove formaldehyde, formaldehyde is a volatile process. Air purifiers can remove formaldehyde from the air, but they cannot do anything about the formaldehyde in the pollution source. So don't point it out for a while. All formaldehyde, this is not realistic.
In addition to formaldehyde has many methods and techniques, such as often window ventilation, or the use of formaldehyde in the characteristics of high temperature and high humidity, let the newly decorated house formaldehyde quickly volatile, air purifiers in this process only play an auxiliary role.
