Formaldehyde Removal Performance

This chart presents the top 10 houseplants for removing formaldehyde, a common indoor air pollutant, measured in micrograms per cubic meter (μg/m³).

Formaldehyde is frequently found in:

• Pressed wood furniture

• Household cleaners

• Paper products

• Synthetic fabrics

• Tobacco smoke

Even low levels can irritate the eyes, nose, throat, and skin, making this chemical especially important to filter in bedrooms, living areas, or offices.

• The Bamboo palm and Janet Craig rank highest, removing significantly more formaldehyde than other species.

• Many of these high performers are large-leaf plants, suggesting surface area may play a role in absorption efficiency.

By analyzing each chemical individually, this chart helps highlight plants that are particularly suited for homes with new furniture, heavy cleaning routines, or limited ventilation.
