How Plants Purify the Air

Here is how the plants purify the air in your house:

Through photosynthesis, the plants take in carbon dioxide that we exhale and, in turn, give us oxygen. In the process, we get purer air. NASA proved this to be true in a study they carried out in 1989. They confirmed that houseplants absorb and neutralize toxic germs and wastes in the air around our houses.

For that reason, having air-cleaning plants will remove air quality in your house, especially in enclosed spaces where air circulation is limited. Plants may not be as effective in air filtering as artificial air purifiers, but plants are natural, beautiful, cheap, and safer to use.

Did you know that sitting among plants improves your mood, memory, concentration, reduces stress and fatigue?

Following the study, NASA recommended that there be at least eight pot plants for every 100 square feet.

You should note that some toxins are best removed by certain plants, so the best bet is to combine different air filtering plant varieties because there are different types of germs floating from your carpets, ovens, etc in your house.

Types of Germs or Harmful Chemicals in Your House

  1. Benzene — It has the potential to cause dizziness, headaches, drowsiness, and fast heartbeat.
  2. Formaldehyde — It causes mouth, nose, and throat irritation.
