Formaldehyde Removal Method 3: Air Purifier

When talking about formaldehyde removal products, many people will think of air purifier. Most air purifiers in the market remove formaldehyde, and they mainly rely on three components:

 

Negative ions: The air purifier releases negative ions into the air, which can be combined with formaldehyde, bacteria, viruses or PM2.5 to make them settle, and negative ions will even degrade formaldehyde into carbon dioxide and water

 

Active carbon: A filter made of activated carbon can absorb formaldehyde during the process of pumping air and filter out odour

 

Photocatalyst: The meaning of photocatalyst refers to the catalysts that use light energy to carry out catalytic reactions, while in formaldehyde removal, titanium dioxide (TiO2) will be used. To put it simple, the filter screen containing titanium dioxide in the air purifier absorbs the passing formaldehyde and uses light to produce catalytic effect, thereby converting the formaldehyde into carbon dioxide or water. In addition to formaldehyde, photocatalysts also have very strong bactericidal and virus-killing capabilities.
