Typical homes are chock-full of items that can be responsible—either by virtue of chemical composition or the way in which they are manufactured—for releasing harmful chemicals into the air. But fear not! Houseplants can be cultivated to filter many of those chemicals right out of the air you breath and look great doing it.
We went through a NASA Clean Air Study and crosschecked all of the houseplants with the ASPCA to provide you with a list of all of the pet-friendly ones. Enjoy the greenery and fresher air in your home!
- Dendrobium Orchids (Dendrobium spp.) With over 1,000 varieties, these flowering beauties filter airborne xylene and toluene particles. Light, temp, and watering requirements vary by type, so careful research for specific varieties is a must.
- Moth Orchids (Phalaenopsis spp.) Also proven to filter xylene and toluene, moth orchids can bloom for up to eight weeks and will flower repeatedly with attentiveness and care.
- Turf Lily (Liriope spicata) Often used outdoors as a landscaping plant, turf lily works well inside to filter formaldehyde, xylene, toluene, and ammonia. While it does not require direct sun, it does need abundant watering and relatively humid air.
- Gerber Daisy (Gerbera jamesonii) Revered for oversized, vibrantly colored blooms, Gerber daisies filter benzene, formaldehyde, and trichloroethylene. For spring through fall, Gerbers want lots of direct morning sun and regular watering plus fertilizer. In winter, less frequent watering and indirect sun are preferred.
- Spider Plant (Chlorophytum comosum) One of the easiest houseplants to grow, spiders also filter formaldehyde, xylene, and toluene. Spider plants thrive in well-drained soil and bright, indirect light. Mature spider plants will produce spiderettes, which you can easily propagate into even more air-filtering plants.
PALMS AND OTHER LEAFY PLANTS
- Dwarf Date Palm (Phoenix roebelenii) For indoor use, look for pygmy date palm, but don’t be fooled by the name; mature plants can reach over six feet tall! Date palms prefer full sun and dry-ish, peat-based soil with lots of drainage. Filters: formaldehyde, xylene, and toluene.
- Areca Palm (Dypsis lutescens) Inside, areca palm grows to 6-7 feet and filters formaldehyde, xylene, and toluene. Areca prefers warm temps and moist, well-drained soil.
- Bamboo Palm (Chamaedorea seifrizii) Filters formaldehyde, xylene, and toluene and will grow in low light conditions. Offer adequate drainage, high-quality potting soil, and filtered water at room temperature.
- Broadleaf Lady Palm (Rhapis excelsa) Filters formaldehyde, xylene, toluene, and ammonia, but grows tall and wide, so reserve for large indoor spaces. There are many species, each with different cultivation requirements so research carefully.
- Boston Fern (Nephrolepis exaltata ‘Bostoniensis’) These lacy green houseplants filter formaldehyde, xylene, and toluene, but are rather finicky about their environment. They want cool temps, high humidity, indirect light, and soil kept consistently damp.
If you have a history of killing off houseplants, this additional advice might help you to mend your ways in pursuit of the best possible indoor air quality!
