10 Tips for Improving Indoor Air Quality in Your Home

You, your family, and guests will breathe easier if you improve your home’s indoor air quality by reducing allergens such as dust mites, mold spores, pollen, fungus and animal dander.

1. It’s the Humidity

Dust mites and molds thrive in humid conditions, so control relative humidity (aim for 35 to 55 percent). Run bathroom exhaust fans during and for 15 minutes after steamy showers. Empty and clean evaporator trays in dehumidifiers, refrigerators and air conditioners on a regular basis. Be sure your central air conditioner drain is working properly and not clogged. Repair roof and plumbing leaks. Reduce condensation on pipes, in walls, and around windows through proper insulation and moisture barrier installation.
2. Keep It Clean
Regular dusting, vacuuming and surface cleaning can reduce the accumulation of dust mites, pollens and pet dander. Use a HEPA-filter vacuum bag or a vacuum cleaner equipped with a HEPA filter to reduce the ejection and re-suspension of vacuumed particles.
3. Ban the Butt
Don’t allow smoking in your home; limit the use of candles, incense and other soot-producing products.
4. In the Bedroom
Buy machine-washable pillows and comforters and launder them regularly in hot water to kill dust mites. Launder sheets and pillowcases every 10 days. Individuals with allergy sensitivities may need additional laundering steps as recommended by their physicians.
5. Let It Flow
For better air circulation, occasionally air out the house on dry days with low pollen counts. Sensitive individuals may wish to isolate the room they occupy most by closing the door and running a room filtration unit.
6. Invest in the Best
Equip your home heating and cooling system with high-performance filters such as DuPont™ Air Filters with advanced Microban® protection, which can help prevent trapped microorganisms from multiplying on the filter surface where they could cause odors and clog the filter.
7. Check and Replace
Check your air filters at least quarterly, and replace them according to the manufacturer recommendations. If your filters do not get dirty, ventilation problems are likely. Inspect your air conditioning and ventilation system for bypasses and leaks. Make sure that your filter is attached securely on all edges and there are no gaps around it.
8. Evict Pests
Keep roaches, mice and rats out of your home. Allergens from roaches are a major cause of asthma, and airborne protein from dried rodent urine is a potent allergen.
9. Don’t Be a Wet Blanket
To avoid harboring mold and bacteria, remove and replace water-damaged carpet and building materials that can’t be thoroughly cleaned and dried within 24 hours after the damage occurs. Confirm that the carpet is thoroughly dry prior to replacing furniture.
10. I’m Just Venting
Be sure that combustion appliances (stoves, fireplaces, furnaces, water heaters, etc.) are properly vented to the outside and the vents are unobstructed. Appliances should be serviced according to the manufacturer’s maintenance schedule to avoid combustion byproduct buildup and reduce dust and particulate accumulation. Unvented gas or kerosene heaters should only be used in open spaces with a partially open window. Check flues and chimneys for debris and cracks that may affect the flow of fumes out of your home.
