Frequently Asked Questions

Which houseplants purify indoor air?

The NASA Clean Air Study identified several houseplants that filter common indoor pollutants like formaldehyde, benzene, and carbon monoxide. Top performers include Spider Plant, Peace Lily, Snake Plant, Pothos, and Boston Fern.

Do air-purifying plants actually work?

The NASA Clean Air Study showed that houseplants can filter certain VOCs and pollutants from the air in controlled conditions. While real-world results are less dramatic, plants do contribute to better indoor air quality and well-being. You would need a significant number of plants to have a measurable effect in a typical room.

Are air-purifying plants safe for pets?

Not all air-purifying plants are pet-safe. Pothos, Peace Lily, and Snake Plant are toxic to cats and dogs despite their air-filtering properties. Spider Plant and Boston Fern are air-purifying plants that are also safe for pets.
