We are now offering commercial grade furnace filters, with FREE delivery to your door!

Did you know? Furnace filters are rated by an industry standard, called a MERV rating. Typical big box store filters are rated at 7 or less. Commercially available filters, such as the type we are carrying are rated 10-11, depending on size. The higher rating means greater filtration of small particles you don't want circulating through your home.

How often should your furnace filter be changed? Every 3 months. Keeping to this schedule not only means a cleaner home, but also reduces power consumption, the risk of equipment malfunction and extends your equipment's working life.

Our subscription service provides ongoing deliveries spaced every 6 months for 1" and 4" filter styles or yearly for Aprilaire filter styles.

What is a MERV rating?

Excerpted from the US EPA Web site:

Minimum Efficiency Reporting Values, or MERVs, report a filter's ability to capture larger particles between 0.3 and 10 microns (µm).

• • This value is helpful in comparing the performance of different filters
• • The rating is derived from a test method developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) [see www.ashrae.org].
• • The higher the MERV rating the better the filter is at trapping specific types of particles.

HEPA is a type of pleated mechanical air filter. It is an acronym for "high efficiency particulate air [filter]" (as officially defined by the U.S. Dept. of Energy). This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm). The diameter specification of 0.3 microns responds to the worst case; the most penetrating particle size (MPPS). Particles that are larger or smaller are trapped with even higher efficiency. Using the worst case particle size results in the worst case efficiency rating (i.e. 99.97% or better for all particle sizes).

All air cleaners require periodic cleaning and filter replacement to function properly. Follow manufacturer's recommendations on maintenance and replacement.
