high-quality air filters is perhaps the single most effective
strategy for improving indoor air quality and
minimizing operation costs.
Air filters work to keep the coils and heat
exchangers on your furnace and air conditioner clean, which
helps the HVAC system to work most efficiently, as well as
prolonging the life of the AC unit.

Different environments have different filtration requirements
— homes and offices place varying
demands; the presence of pets and level of traffic are also factors
to consider. If asthma or allergy sufferers spend time in the home or office,
removing allergens from the air stream is even more important.

The Environmental Protection Agency (EPA)
estimates that pollution inside your home or office is typically
five times worse than outside air. The air in your home or office is
with tiny particles —
most one micron and smaller in size (a human hair
is about 45 microns in diameter). This microscopic particulate is
made up of pollen, pet dander, mold spores, bacteria, viruses,
dusts, smoke and more. Dirty air can have adverse health effects,
particularly to the upper respiratory tract, and especially for
allergy sufferers. It can also mean a
dirtier, dustier home or office, with particles settling on surfaces
and embedding in furniture and carpeting. Furnace, air conditioner, HVAC systems can't operate
at optimum efficiency when clogged filters prevent free airflow. And
this can also negatively impact the longevity and efficiency of costly
heating and air conditioning systems.

What Are the
Different Air Filter Types?
Panel/Link Panel Air Filters - Constructed of two to four
layers of laminated synthetic filter media, these anti-microbial air
conditioner and furnace filters feature an internal
corrosion-resistant frame. The friction-fit gasket selvage edge
minimizes inefficient dirty air bypass. Panels may be linked to create one
filter for the entire width of your air handler. Our
Filters are a 2-ply ring panel air filter designed specifically for
furnace and air conditioner. These air filters last 100 days under
normal operating conditions.
Conditioner and Furnace Filters - Generally made of a high-loft, non-woven
cotton/synthetic blend media with a moisture-resistant frame, the
v-shaped pleats achieve higher surface area than standard disposable
fiberglass filters, for maximum airflow and enhanced particulate
capture. Most should be changed every 90 days. We carry pleated
filters in a variety of efficiencies, including
MERV 8 and
Electrostatic Replacement Filters - Permanent,
washable filters that carry an
electronic charge, which acts as an attractant to airborne particles
— dust, mold, dander, pollen, mildew, bacteria, viruses
and fungi. Not all electrostatic filters are equal; filters
constructed with foam or polyester filling can deteriorate or clog (that's
why these filters typically only offer a 5-10 year warranty). Our
ULTRA Electrostatic filters are totally constructed of a
polypropylene fabric and come with a
Electrostatic air filters should be washed periodically with a mild
detergent and warm water.
What's in A MERV?
is an industry standard rating for air filters that measures their ability to trap particles ranging in size from 3 to 10
microns. Home air filters commonly have MERV ratings from 1 to 12
— the higher the rating, the more efficient the
air filter is at trapping particles.
To determine a MERV, solid particles
of varying sizes are introduced into the test system, upstream from
the test air filter. A laser particle counter alternately samples air
upstream and downstream from the test filter. This is done on the
clean filter and after five dust feedings. The lowest efficiency for
each range is used to determine the Composite Minimum Efficiency and
assign a MERV rating
