The Benefits Of Air Cleaning House Plants
Some indoor plants are more than just a decoration for your home, store or office. Many of them, especially tropical or desert plants, are very efficient air cleaners that can help fight such indoors air pollutants as:
- Acetone, which is often emitted from printer ink, printed newspapers, office correction fluid, cosmetics, hair products, nail polish remover, cleaning fluids and car exhaust
- Alcohols, which are found in adhesives, caulking, carpeting, ceiling tiles, duplicating machines, printers. floor and wood floor plastic mat coverings, particle boards, varnishes and plastic blinds
- Ammonia, which is found in cleaning products, printers, photocopiers, bio-effluents and kitty litter
- Benzene, which is found in adhesives, caulking, ceiling tile, paint, particle board, plastic mats, mattresses, photocopiers, stains, tobacco smoke and wall coverings
- Chloroform, which is found in some tap water
- Formaldehyde which is found in adhesives, caulking, ceiling tiles, printers, floor coverings, drapes, upholstery, mattresses, grocery bags, gas stoves, particle board, plywood, stains, varnish and clothing, bedding and furnishings made from permanent press fabric
- Trichloroethylene, which is duplicating machines, printers, and photocopiers
- Xylene, which is found in adhesives, caulking, computer screens, printers, floor covering, particle boards, photocopiers, stains, varnishings, blinds, and wallpaper
Aside from chemicals, indoor air pollution is also caused by:
- Toxic fibrous insulation materials that shed airborne particulates
- Dirty air conditioner systems that shoot particulates, mold, and bacteria into the air
- Very high humidity, which can cause the growth of mold and bacteria
- Very low humidity, which can promote the creation of dirt particulates in the air, known as dust
Having these chemicals and irritants in the air in your home over the long term can lead to allergies, environmental sensitivities and long-term and chronic illnesses such as cancer, COPD, and autoimmune problems. Certain houseplants can actually help eliminate these pollutants from your indoor environment so that you do not have long-term consequences from inhaling them.
