The treatment of formaldehyde includes two stages. If it is a newly renovated house, it is suggested to take a one-time centralized treatment to remove free formaldehyde from the air and furniture surface first. This one-time treatment may only keep the safety limit for a period of time, and the release of formaldehyde is slow and long, which can last for 3- 15 years.
It is suggested that after one-time treatment, combined with air purifier, the filter element dedicated to aldehyde removal is more efficient and safer to use.
