Why can an air purifier remove formaldehyde?
It is reported that the World Health Organization has already identified formaldehyde as a class of carcinogens, and a cancer event such as leukemia caused by formaldehyde poisoning is strong evidence for this conclusion! With the frequent occurrence of formaldehyde poisoning, our fear of formaldehyde can be said to be deep into the bone marrow. Therefore, in order to control formaldehyde and improve indoor air quality, most households will choose an air purifier to remove formaldehyde, then the air purifier can In addition to formaldehyde? What is the way to remove formaldehyde?
As we all know, the purification ability of the air purifier is mainly reflected by the filter screen. Under normal circumstances, the filter screen of the air purifier is roughly divided into a primary effect filter, a HEPA filter, and an activated carbon filter. The primary filter and the HEPA filter are not mentioned for the time being. The activated carbon filter is the filter used to remove formaldehyde. Of course, the composite filter is the same. It relies on the activated carbon inside to absorb formaldehyde!
The principle of activated carbon adsorption of formaldehyde is to rely on its own developed pore structure and surface area, can contact the surrounding air to a large extent, passively adsorb some pollutants into its own pores, so the larger the surface of activated carbon, the more the pore structure The stronger the developed adsorption capacity. However, activated carbon has a fatal disadvantage, that is, the dust holding capacity is too small. Under normal circumstances, the activated carbon will reach saturation in about 15 days, and then secondary pollution will occur. The volatilization period of formaldehyde can be up to 15 years, which means that we need to replace the activated carbon filter frequently, which not only increases the cost of use but also causes negligence, which will cause irreversible consequences. The air purifier of the activated carbon filter to remove formaldehyde is not reliable!
So why do many people think that air purifiers can remove formaldehyde? This is because, unlike traditional air purifiers, there are a number of brands with advanced technology and excellent quality, such as the Olansi air purifier. In order to solve the drawbacks of activated carbon filters, a new type of nano-mineral filter is adopted. The pores of the nano-mineral crystals are nano-scale, and the pores have polar characteristics and have strong adsorption effects on nano-scale molecular-sized polar gas compounds. Be aware that indoor gas pollutants such as formaldehyde are polar gas compounds!
In addition, the pore surface area of the nano-mineral crystal is 6-9 times that of ordinary activated carbon, which directly increases the contact area with formaldehyde, in other words, the efficiency of adsorbing formaldehyde is increased by 6-9 times, the adsorption rate is faster, and Due to the large pore area, the dust holding capacity is far greater than that of ordinary activated carbon. In order to better control formaldehyde, the Olansi air purifier has also developed MSD formaldehyde decomposition technology, which will decompose formaldehyde into carbon dioxide and water while completely adsorbing formaldehyde, completely eliminating secondary pollution.
