Formaldehyde is commonly found in newer structures in glues, plywood, carpeting, etc. The materials eventually release it into the air, which degrades air quality. It was shown that some common types of houseplants reduce formaldehyde by 80% compared to the control (no plant) of about 7% over a 4-5 our period.
