It probably comes as no surprise that there is dust invading your home. The amount, however, is remarkable: Studies have shown that a typical six-room American residence accumulates over 40 pounds of dust every year. Most airborne dust originates inside the house versus from outdoor sources. The diverse list includes carpet fibers, human skin flakes, spores from indoor mold growth, powder from drywall construction materials, fragments of dead insects, lint from bedding and pet hair and dander.
Some of the dust invading your home is an inevitable result of human occupation. However, it’s still feasible to reduce that 40-pound annual figure to a more manageable amount.
Don’t Spread It Around
Dust on surfaces can be removed with electrostatic microfiber cloths that retain dust. However, vacuuming carpets often stirs up large volumes of dust into the air instead of capturing it. To avoid re-distributing dust throughout the house, use a vacuum that incorporates a HEPA-grade filter and bags rated to retain dust particles as small as 5 microns.
Choose Quality Air Filters
The entire volume of air inside your home—including the dust floating in it—passes through the HVAC air filter multiple times each day. Cheap fiberglass filters don’t extract dust particles efficiently. Replace with quality pleated cotton or polyester filters with a MERV (Minimum Efficiency Reporting Value) around 8. Change the air filter monthly during cooling season and every other month during heating season.
Maintain Your Ductwork
Leaky, deteriorating ductwork actually sucks in air from dusty parts of the structure such as the attic and crawl space, then circulates that dust into living spaces of the house. Have your ducts inspected and tested for leakage by a qualified HVAC contractor. Options for repair and sealing of ductwork help reduce dust circulation.
Rotate Bedding Weekly
Beds are a repository of shed skin flakes that contribute airborne dust every time you fluff the sheets. Wash pillowcases and sheets every week. Items that don’t require regular washing like blankets and bedspreads should be taken outside and shaken vigorously.
