Improving Indoor Air Quality – VOC eating Plants – Hepa Air Filters
Posted by Norman Fong
Indoor Air Quality refers to how clean the air indoors is. We spend 90-95% of our time indoors. Often times the air outside is cleaner. This leads to health problems like allergies, asthma, etc.
Major air quality problems include: Smoking, Fireplaces, Mold, Dust, Radon, Stoves.
Some lesser known problems include: Offgassing of volatile organic compounds (VOCs) and other chemicals from paint, carpets, cleaners, gasoline, paint thinner, dryclean clothes, office equipment, furniture, and building materials.
Using Plants to Scrub the Air
NASA has done research to show that plants Clean Air and Water for Indoor Environments. Plants have been found to reduce dust, formaldehyde, benzene, and other harmful chemicals. Air purification using plants is called phytoremediation. Recent research conducted at universities found that certain plants reduced total VOC levels by up to 75%. Plants clean the air by absorbing chemicals through small leaf pores called stomata . And from microorganisms living in the soil.
List of Plants that Purify the Air
Plants that are recommended include:
- Areca palm (Dypsis lutescens)
- Asparagus fern
- Bamboo palm (Chamaedora seifritzee)
- Boston fern (Nephrolepis exaltata)
- Chinese evergreen
- Corn Plant
- Devils ivy
- Elephant ear philodendron (Philodendron domesticum)
- English ivy (Hedera helix)
- Flamingo flower
- Gerbera daisy
- Golden pothos (Scindapsus aureus)
- Grape Ivy
- Janet Craig
- Kimberly Queen fern (Nephrolepis obliterate)
- Mother in-laws tongue
- Peace lily (Spathiphyllum clevelandii)
- Pot Mum
- Snake plants
- Spider plants (Chlorophytum elatum)
- Tulip Orchid
- Weeping fig (Ficus benjamina)
One or two plants can clean approximately 100 square feet. Formaldehyde is no longer detectable if you have 1 or 2 Boston ferns within a 100 square feet space.
Removing common chemicals from the air
Formaldehyde, benzene and trichloroethylene are three common toxic indoor chemicals that should be removed from the air. Philodendron and spider plants remove formaldehyde; English ivy and Marginata remove the large amounts of benzene; and Gerbera daisy and the Peace Lily are very good in removing trichloroethylene.
Penn State recommends plants for improving air quality too.
Make sure that you do not over water your indoor plants. Mold occurs typically when house plants are watered too much or too often.
If you have carpet, consider removing it or using modular green carpets such as Interface floor. Install using no voc adhesives.
Filtering your air
Putting a better filter on your heater, such as a 3M Filtrete will also improve indoor air quality.
In room portable air purifiers with HEPA filters also help clear the air. Look for ones that are whisper quiet.
Also consider installing a high-quality whole house air filtration system such as one from Aprilaire. These filters, filter the year before it reaches your heating system. Neutralize most germs, dust, mold spores and other air borne pollutants.
This is a lot cheaper and more green and eco than buying lots of air purifiers or replacing every piece of furniture you have.
Air Duct Cleaning and Vent Cleaning
I keep hearing Air Duct and Vent Cleaning commercials on the radio. Clearly it is a big business. They brush and vacuum up each air duct and into each return where possible. It is supposed to help remove dust, mold, etc especially helpful for people with allergies.
The American Lung Association has said that Duct Cleaning hasn’t been shown to prevent health issues nor has it been shown that dirty air ducts cause more dust. U.S. Environmental Protection Agency does not recommend that air ducts be cleaned routinely, only when they are dirty.
Be sure to Fix Leaky Ducts – Reducing Air Leaks
