activated carbon
Activated carbon is the cheapest and most effective thing to adsorb impurities, but it is easy to saturate and rebound, so it needs to be replaced with a new carbon bag regularly.
Fresh air system
Fresh air system is the most effective technology in in addition to formaldehyde at present, which can be used for a long time. Moreover, the fresh air system can satisfy families to enjoy the flowing fresh air without opening the window and keep the indoor air fresh.
