Houseplants instantly add color and texture to any space — whether they’re used to decorate your bedroom, spruce up an office or add some pizzazz to a bookshelf. It’s no secret that being surrounded by greenery does wonders for our physical and mental health. Certain greens have been found to not only purify the air, but provide allergy relief, improve sleep quality and reduce stress levels.
According to NASA’s landmark 1989 study, a number of popular houseplants — like English Ivy and Bamboo Palm — diffuse toxic chemicals including Formaldehyde, Benzene and Trichloroethylene. Keep in mind that plants with larger leaves (think: palms) purify air quicker, while trailing plants (think: ferns and ivy) take up the most surface area.
When shopping for houseplants, it’s important to consider more than just aesthetics. Don’t forget about the safety of your dogs, cats and small children, too! To help you out, we’ve complied the best air-purifying houseplants — including a ton of pet-friendly greenery and low-maintenance picks for beginners. And, don’t worry: all of these plants will also elevate your home decor.
How do plants purify air?
During photosynthesis, plants convert the carbon dioxide we exhale into fresh oxygen and remove toxins from the air we breathe. Popular houseplants that have been found to purify indoor air by filtering out toxic chemicals like:
- Formaldehyde, which can cause irritation to nose, mouth and throat.
- Benzene can cause drowsiness, dizziness and headaches, and can eventually cause harmful effects on the bone marrow and a decrease in red blood cells.
- Trichloroethylene, which can cause dizziness, headache, confusion and weakness.
