Types of Houseplants That Clean Indoor Air
Why invest in expensive electrical air purifiers when you could purchase a few types of houseplants to clean and filter the air naturally and inexpensively?Much of the research on these beneficial houseplants has been done by NASA scientists researching ways to create suitable space station habitats. All indoors plants (flowering or not) are able to purify indoor air to some degree through their normal photosynthesis processes. But some were found to be more beneficial than others in removing harmful household toxins, even removing 90% of chemicals in the air in only twenty-four hours!
The three main household toxins of concern are:
- benzene
- formaldahyde
- trichloroethylene
