10 Ways to Improve Indoor Air Quality

The Environmental Protection Agency estimates that people spend 90% of their time indoors, but that indoor air quality can be two to five times more polluted than outdoor air. Whether in your home or business, follow these 10 easy steps to ensuring you have the cleanest indoor air possible.

Get Clean Air

1. Don't Allow Smoking Indoors - There is no safe level of second hand smoke. Each year, second hand smoke sends 7,500-15,000 children aged 18 months or younger to the hospital. Hundreds of thousands of children will develop respiratory tract infections from second hand smoke this year. It's not even good enough to allow smoking outside of doors or on balconies, as the smoke simply re-enters indoors. Try to designate a smoking area at least 20 feet away from the premises.

2. Carbon Monoxide Detector - Carbon monoxide is an odorless gas that kills over 400 people each year. Carbon monoxide levels can rise very quickly in unventilated areas. Make sure you install a functioning detector in your home, preferably near your bedroom.

3. Test for Radon - Scientists estimate that radon causes thousands of deaths annually. Radon is an odorless, invisible gas that occurs naturally in soil and rock and can only be detected through testing.

4. Fix Leaks - Rain and high humidity can bring moisture indoors, creating dampness, mold and mildew. Mold aside, dampness alone is associated with higher risk of wheezing, coughing and asthma symptoms. Check your roof, foundation and basement or crawlspace once a year to catch leaks or moisture problems and route water away from the building's foundation.

5. Air Conditioners and Dehumidifiers - Asthma is the leading serious chronic illness of children in the U.S. Help keep asthma triggers away by fixing leaks and drips as soon as they start. Standing water and high humidity encourage the growth of dust mites, mold and mildew, some of the most common triggers that can worsen asthma. Use a dehumidifier or air conditioner when needed, and clean both regularly - or get one that's self-evaporative.

6. Pets - Pet allergies can come from an animal’s saliva, urine, feces and dead skin cells, so no pet is “hypoallergenic.” If someone in your family has pet allergies, keep your pet outdoors. Moving your pet from indoors to out can help reduce exposure to these allergens. However, cat allergens can stay in place for 20 weeks or more. If you must keep your pet indoors in public spaces, keep it away from primary heavily trafficked areas.

7. Dust Mites - Dust allergies are actually a reaction to dust mites. Dust mites are microscopic pests that need moisture to survive. Since dust mites feed on human skin, and live in bedding, pillows, mattresses, stuffed toys, upholstery and carpets. Dust mites can be controlled through intensive vacuuming, wood/linoleum floors (versus carpets), and keeping humidity levels below 50% (this can be achieved through a dehumidifier).

8. Asbestos Control - Asbestos is a mineral fiber that can still be found in many older homes. Inhaling tiny asbestos fibers can increase the risk of lung cancer and other lung diseases. Pipe coverings, flooring, shingles and roofs are likely places to find asbestos.

9. Ventilation - Proper ventilation is one of the best ways to improve air quality, (provided that the outside air is not worse than indoor air). High levels of moisture in your home increase dampness and the growth of mold, which not only damage your home but threaten health. Dampness and mold are linked to increased wheezing, coughing and asthma attacks in people with allergies. Consider investing in a UV Air Purifier that removes allergens as well as odors and infectious microorganisms.

10. Flooring - Avoid using carpet whenever possible. Carpet traps unhealthy particles -- including chemicals, dust mites, pet dander, dirt and fungi - and vacuuming can make them airborne. If you do have carpets, use a HEPA (high efficiency particle air) vacuum cleaner to ensure better air quality. Hard surface flooring, like wood, tile or cork can be readily cleaned by damp mopping. With these ten steps, you should be well on your way to cleaner indoor air.

Green Facts

  • One recycled aluminum can will save enough energy to run a 100-watt bulb for 20 hours, a computer for 3 hours, or a TV for 2 hours.

  • A single quart of motor oil, if disposed of improperly, can contaminate up to 2,000,000 gallons of fresh water.

  • Recycling 100 million cell phones can save enough energy to power 18,500 homes in the U.S. for a year.

  • Nudge your thermostat up two degrees in the summer and down two degrees in the winter to prevent 2,000 pounds of carbon dioxide from entering the atmosphere.

  • Americans throw away more than 120 million cell phones each year, which contribute 60,000 tons of waste to landfills annually.

  • Due to tiger poaching, habitat destruction, and other human-tiger conflicts, tigers now number around 3,200—a decrease in population by about 70% from 100 years ago.

  • Plastic bags and other plastic garbage thrown into the ocean kill as many as 1,000,000 sea creatures every year.

  • 77% of people who commute to work by car drive alone.

  • Current sea ice levels are at least 47% lower than they were in 1979.

  • An aluminum can that is thrown away instead of recycled will still be a can 500 years from now!

  • Every week about 20 species of plants and animals become extinct.

  • For every 38,000 bills consumers pay online instead of by mail, 5,058 pounds of greenhouse gases are avoided and two tons of trees are preserved.

  • Recycling 1 million laptop computers can save the amount of energy used by 3,657 homes in the U.S. over the course of a year.

  • If every U.S. household turned the thermostat down by 10 degrees for seven hours each night during the cold months, and seven hours each weekday, it would prevent nearly gas emissions.

  • Rainforests are being cut down at the rate of 100 acres per minute.

  • 82 percent of greenhouse gas emissions in the U.S. come from burning fossil fuels.

  • Glass can be recycled over and over again without ever wearing down.
