Many people buy air purifiers in order to remove indoor odors, fresh room air, especially in the home with small animals, and the elderly and children, the indoor air requirements are relatively high. Then there will be more or less formaldehyde in newly decorated houses and furniture, and the use of air purifiers can adsorb such toxic substances. So does the air purifier have any effect on removing formaldehyde?
1. Is the air purifier really effective in removing formaldehyde?
Air purifiers can remove formaldehyde, but their effect is very limited. The principle of air purifier is mostly the use of physical filtration and adsorption capacity to remove harmful substances in indoor air, such as dust, animal hair, second-hand smoke, lampblack and so on, so as to purify the air. Of course, some formaldehyde molecules in the air can also be adsorbed, but can not be decomposed, which is likely to cause "secondary pollution", that is, it is difficult to achieve an obvious effect. In addition, air purifier can only help remove formaldehyde. If there is a lot of formaldehyde in the home, air purifier alone is completely not good. It must be eliminated through professional corporate governance. Unless there are relatively few pollutants such as formaldehyde in the home, it can be removed using an air purifier.
2. What air purifier is the best to remove formaldehyde?
If you want to remove formaldehyde, you must choose a purifier with a filter element that removes formaldehyde. Ordinary filter elements generally cannot remove formaldehyde.
If you want to remove formaldehyde, you must choose a purifier with a filter element that removes formaldehyde. Ordinary filter elements generally cannot remove formaldehyde. Then it is to choose a big brand and high quality air purifier, and compare some comprehensive indicators such as formaldehyde CADR value, formaldehyde CCM value, formaldehyde removal rate and so on. In addition, it is necessary to consider formaldehyde removal technology, machine quality and so on.
Most household air purifiers are passive filters, and usually have a "primary effect + activated carbon + efficient" three-layer design, in order to achieve the purpose of filtration and purification of air, and the removal of formaldehyde usually absorbs free formaldehyde in the air through the activated carbon filter, to achieve the effect of removal of formaldehyde. In addition to this purely passive method of removal, there are methods of degradation to CARBON dioxide and water by negative oxygen ions and catalytic decomposition by photocatalysts.

3. The functions of air purifier
1) Air purifier can effectively remove all kinds of inhalable suspended particles in the air, such as dust, coal dust, smoke, etc., and prevent the human body from inhaling these harmful floating dust particles.
2) Air purifiers can effectively absorb bacteria, viruses, molds and molds from the air and surfaces, while removing dead dander, pollen and other sources of disease from the air, reducing the spread of diseases in the air.
3) Air purifier can effectively eliminate the odor and pollution of the air emitted by chemicals, animals, tobacco, lampblack, cooking, decoration, garbage, etc., and purify indoor air 24 hours a day to ensure a benign cycle of indoor air.
4) Some air purifiers can effectively remove volatile organic compounds (VOCs), formaldehyde, benzene, pesticides, hydrocarbons, paints, furniture, decorations and other harmful gases released, and avoid allergies caused by inhaling harmful gases. Physical symptoms such as cough, pharyngitis and pneumonia.
