Do you see duct particles in the air when a beam of sunlight passes through your window? Dust particles of course are easy to spot when they adhere to your furniture. The average house is believed to contain about 3 million dust particles in every cubic foot of air. If you suffer with allergies, asthma or other respiratory problems, then you are no doubt sensitive to airborne particles – which can cause you big problems. The generic term “dust” can include in its meaning – dead skin, mold, pet dander, cooking smoke, cigarette smoke & ash, fireplace smoke & ash, mildew, fungi, pollen, etc.
Specialty air cleaners, purifiers and filters are designed to remove dust from indoor air. Visible dust is about 10 microns in diameter – the type that can lodge in your lungs can be about .3 microns. The tip of a sharp pencil is about 200 microns in diameter. Small self-contained air cleaners are available that sit on tabletops or floors and generally serve single rooms.
Whole-house filters can be attached to your home’s forced-air furnace. They work by mechanical filtration, electrical attraction or a combination of the two.
Electrostatic precipitation air cleaners usually draw particles in with the use of a fan and charge the particles with a series of high-voltage wires. Precipitation cells (a series of plates) carry an opposite electrical charge to attract the particles to the plates as they pass by.
Whole-house filtering methods can be very effective at removing odors, some gases, pollens and other dirt particles. Generally up to about 95% of bulk dirt and 85% of microscopic particles can be removed with the right system when correctly installed.
The Most Effective ways to enhance the quality of your indoor air
State-of-the-art Carrier air filtration systems such as Carrier’s Infinity™ Air Purifier and Performance Electronic Air Cleaner effectively remove bacteria, pollen, animal dander and other pollutants as small as 0.01 microns–that’s 18,000 times smaller than the head of a pin. The higher the MERV rating, the more efficiently the cleaner removes particles.
