9 Air-Purifying Plants And How To Care For Them

Authored By Emily

One of the side effects of living or working in a modern, energy efficient residence can be reduced air flow which allows for the buildup of indoor air pollution which can lead to health issues such as asthma. As a matter of fact, your carpet, modern furnishings and even artificial building materials could be carrying more chemicals and pollutants than expected which comprise of up to 90% of indoor pollution.

Plants as Air Purifiers

The National Aeronautics and Space Administration (NASA) found out that there are houseplants that can take up harmful toxins from the air in 1998, particularly in enclosed spaces with diminished air flow. This research has been the footing for more current studies concerning indoor plants and their air-cleansing capabilities. Plants may have less power than actual air purifiers but they are therapeutic, cost-effective and more natural. Plants have been known to

  • Decrease fatigue and stress
  • Boost memory and concentration
  • Increase productivity and improve mood.
NASA advocates for 2 or 3 plants in pots that are 8-10 inches for every 100 square feet of indoor space. Certain plants remove particular chemicals more efficiently than others. Some of the household chemicals we may come into contact with from materials and objects include:
  • Synthetic materials like rubber, fiber, and plastic
  • Cleaning solutions
  • Ovens
  • Glues
  • Carpets

When you include an assortment of plants in a room you will benefit the most. Safety concerns when buying indoor plants If you have pets such as dogs and cats you may want to re-think buying air-purifying plants because a good number of these plants might be toxic to them. You can enquire from the staff about allergy-safe and pet-safe options at your local greenhouse. Alternatively, you can look up plants that are toxic to animals on the page for ASPCA Toxic and Non-Toxic Plants. More plants can also influence humidity and stimulate mold growth but you can prohibit this by allowing the water to drain into a tray or a pan, using sub-irrigation planters and regularly removing excess water. To remove mold, cover the top of the soil with aquarium gravel or Spanish moss.
