It goes without saying that indoor air quality can affect human health. Indoor air is often more polluted than outside air. There are many strategies to help clean the air, like mechanical air filters. House plants and the microorganisms associated with them offer another method for cleaning the air. Or do they? The Centre for Environmental and Marine Studies put this to the test and reported:

The presence of potted plants likely favored a decrease of approximately 30% in PM₁₀ concentrations. Our findings corroborate the results of NASA studies suggesting that plants might improve indoor air and make interior breathing spaces healthier.

“PM” means “particulate matter“, which are extremely tiny particles that tend to be inhaled deep into the lungs and can have toxic effects.

Plants that clean the air the most include: peace lily, philodendron, mother-in-law’s tongue, spider plants, asparagus ferns, English ivy, bamboo palms, purple heart plant, pothos, potted mums, gerbera daisy, and orchids.

Besides this, greenery beautifies.

If you do a lot of indoor exercise, consider getting more houseplants to clean your air.
