Pomelo peel and the like only cover up the smell and can't achieve any removal effect. The energy absorbed by green plants is very limited. Photocatalyst can remove formaldehyde from the air, but it will rebound after a while. Because long-term pollution sources will continuously release formaldehyde, it is suggested to choose wood-based panels (long-term formaldehyde emission pollution sources) as formaldehyde removal agents, but now many products on the market also have this name, so be careful when choosing. It is recommended to buy a small amount and try it first. If you don't rebound.

Formaldehyde pollution is divided into long-term pollution sources and short-term pollution sources. Generally, it is necessary to control long-term pollution sources, because short-term pollution sources may evaporate in about half a year, but attention should be paid to ventilation, and the release cycle of long-term pollution sources is as long as several years.
