Houseplants are awesome air cleaners, but some of them are more effective than others at filtering out pollution and toxic chemicals in the air.
Houseplants are not something you would typically associate with NASA, but the US government agency did some interesting research on the subject. The study, led by Dr. B. C. Wolverton, found that the plants below are effective at filtering out the likes of benzene, ammonia and formaldehyde from the air, helping to neutralise health effects like headaches and eye irritation linked to these chemicals.
The aptly named 'Florist's Mum' proved most effective, alongside the Peace Lily, both shown to filter out amounts of benzene, formaldehyde, trichloroethylene, xylene, toluene and ammonia.
