The three main household toxins of concern are:
  • benzene
  • formaldahyde
  • trichloroethylene
These carcinogenic chemicals are used in the manufacturing of synthetic substances and materials and are off-gased from new materials for some time (up to several years, depending on the material of product in question). Benzene can also be emitted from gas ranges during use, making some types of houseplants below great for use in the kitchen.
This means these types of houseplants may just decrease your risk of cancers, asthma, allergies, auto-immune disorders and other diseases.
