Air Purifier: Let Formaldehyde Become Nowhere
Aug 24, 2018

Moving to a  new home or renovating an old home is supposed to be a happy event to  enhance happiness. However, potential decoration pollution has become  our health killer. As a widely used organic synthetic raw material,  formaldehyde is widely used in particleboard and coatings. These two materials cover almost the entire home improvement industry.

Formaldehyde  is a colorless and harmful gas. Long-term exposure may cause headache,  dizziness, fatigue, decreased immunity, and symptoms such as drowsiness,  memory loss and neurasthenia. It also has serious effects on the liver  and respiratory system. Formaldehyde is not only harmful  but also has a long incubation period. The volatility is as long as 3 to  15 years. Especially in the hot summer, the amount of formaldehyde will  increase significantly. This is undoubtedly very good for pregnant  women, the elderly and children with less resistance. Great health hazards.


Traditional formaldehyde removal methods may not work


In  China's "Indoor Air Quality Standards", the limit of formaldehyde in  indoor air of Class II civil construction projects is 0.10mg/m3, and the  limit of formaldehyde in indoor air of a type of civil construction  project is 0.08mg/m3. In fact, in the continuous  publicity and education, the public has fully understood the harm of  formaldehyde. It is not unusual for the whole people to get rid of  formaldehyde. But what do you insist on in addition to the small  remedies for formaldehyde?


In this  experiment, we can understand that whether it is leftover tea,  grapefruit peel, green radish, activated carbon, their adsorption effect  is very limited, using the taste of the article itself to cover up the  smell of formaldehyde pungent, the actual behavior is like a slap in the  face, except Let the smell discomfort be relieved, they actually can not achieve the role of formaldehyde.


Many people  think that throwing a few bags of activated carbon or a few plates of  plants can achieve the effect of removing formaldehyde. In fact, their  adsorption of formaldehyde is very limited. The data from Tsinghua  University Environmental College can be more intuitively understood,  activated carbon and Plants have very little effect on the  adsorption of formaldehyde. To make them have a certain formaldehyde  adsorption effect, it often requires hundreds or more than 10 kilograms  of adsorbent material to achieve a better adsorption of formaldehyde.


Ventilation  and adsorption are the best solutions for diluting formaldehyde  concentration. In reality, under dust, haze, rain and other conditions  without ventilation, effective adsorption becomes the second solution  for diluting formaldehyde, which has the effect of efficiently filtering  formaldehyde. The air purifier naturally became the first push of formaldehyde nemesis.
