Indoor air pollutants are all around us. They include pollen, molds, fungal spores, viruses, bacteria, smoke, gas combustion by-products, outgassing from carpets, furniture, plywood, and drywall, cleaning supplies and other personal care items, pet dander, dust mites and their feces and body fragments, cockroach body parts, and more. Disgusting!
In the past 20 years, an emerging and expanding body of evidence has shown that indoor air quality has tremendous impact on human health. Americans-especially infants, the elderly, and persons with chronic diseases-typically spend 90% of their time indoors where they can be exposed to very high levels of air pollutants.
Indoor Air Quality Facts
- People spend 75-90% of their time indoors
- Exposure to airborne contamination is considerable
- 50% of all major office buildings have contaminated heating, ventilation and air conditioning systems (HVAC). If not properly maintained, they are a hotbed for growth of molds and bacteria.
- Each person inhales over 3,500 gallons of air each day. Children inhale more particles for their size than adolescents or adults.
- Polluted air causes 94% of all respiratory problems
- More than 31 million Americans have been diagnosed with asthma, about 1/3 are children under 18.
- About 40,000 dust mites, a common household allergen, can live in one ounce of dust
- An estimated 10-15% of the entire population may be allergic to cat or dog dander.
- A person sheds up to 700,000 skin flakes per day.
Worse, it’s unhealthy. 50 million Americans suffer from allergies and 20 million have asthma. Tighter building envelopes in the quest for greater energy efficiency are making things worse. We spend most of our time indoors, surrounded by the indoor air pollutants. The larger pollutants (less than 10 microns; a human hair is 30 to 120 microns in diameter) are caught in our noses and throats. Smaller pollutants are inhaled into our lungs where they can remain trapped for years.
John L. Kirkwood, President and CEO of the American Lung Association® says, “Keeping the air in your home clean is particularly important for people with asthma or allergies, but the quality of indoor air is something all Americans should be concerned about.” – American Lung Association®
What can you do?
Three ways to fight indoor air pollution:
The starting point for a home indoor air quality strategy is source control. It makes sense. If you can control a pollutant before it becomes airborne, you’re ahead of the game. Source control strategies include the use of low emission paints, varnishes, and carpeting, no smoking, no pets, maintaining optimum humidity levels, regular cleaning, and regular servicing of combustion appliances, such as furnaces. Unfortunately, you cannot always control pollutant sources.
Use your air conditioner to control humidity in the summer and a duct mounted humidifier in the winter. Get your furnace serviced every fall. The most economical approach to maintenance is a Central Heating and Air Conditioning service agreement.
After source control, comes fresh air ventilation. According to the EPA, the air inside your home is far worse than outside air. Yet, when it’s really hot or really cold, who’s going to open the windows? It’s uncomfortable and unaffordable.
There is a solution for some homes that improves fresh ventilation without the comfort or energy costs. It’s called an energy recovery ventilator. Not only can it improve air quality, it can actually reduce utilities in certain circumstances.
The third way to fight indoor air pollution is air cleaning. Do not buy the cheap tabletop and gadget air cleaners you hear advertised. They are a waste of money. According to an American Lung Association® report, “The reviewed data provide little reason to endorse the use of inexpensive tabletop, appliance-type air cleaners, regardless of the technology they employ. In general, high-efficiency particle collection requires larger filters or electronic air cleaners.”
Air cleaning is recognized as one of the three strategies to improve indoor air quality and has become increasingly popular as specific populations of individuals attempt to improve the air quality in their residences and immediate environs to relieve symptoms associated with various diseases such as asthma, rhinitis, sinusitis, and allergic respiratory disease.
We recommend a whole-house approach with a duct mounted UV light and either a HEPA filtration system or an electronic air cleaner. What’s appropriate for your home depends on your budget, comfort system, and family. — American Lung Association® report
