Is an air purifier sufficient to deal with formaldehyde?

An air purifier is a common method for addressing indoor formaldehyde. It uses high-efficiency filters to remove airborne pollutants and improve air quality in real-time. However, the purification process can take time, and depending on the indoor area, the air purifier may need to be continuously operated for at least 4-5 hours per day. It may not be able to completely eliminate formaldehyde that is trapped within wooden furniture or materials.
