is an efficiency or MERV rating?
Most filters are labeled with a MERV
(Minimum Efficiency Reporting Value)
rating number, which measures a filter's ability to trap particles ranging in size from 3.0 microns to 10.0 microns.
Residential filters commonly have MERV ratings of
1-11. The higher the MERV rating, the more efficient the filter is, and the more particles it can filter.
• A MERV rating of 6 means the filter is 35% to 50% minimum efficient at capturing particles, sized 3.0-10.0 microns.
• A MERV rating of 7 means the filter is
50% to 70% minimum efficient at capturing particles, sized 3.0-10.0 microns.
• A MERV rating of 8 means the filter is 70% minimum efficient at capturing
particles, sized 3.0-10.0 microns.
• A MERV rating of 11 means the filter is 85% minimum efficient at capturing
particles, sized 3.0-10.0 microns.
MERV is an industry standard rating, so it can be used to compare filters made by different companies.

Home air filters © also commonly called "furnace filters" © keep the coils and heat exchanges on the heating and air conditioning system clean. Dirty coils and heat exchanges make the system work harder, so keeping the filter clean helps prolong the life of your HVAC unit.
Of course, the filters also clean the air that you and your family breathe. The variety and amount of particles in your home's air will depend on how many people and pets live in the house and what types of activities go on there. People with allergies or asthma should be extra diligent about keeping home air filters
clean. The most important thing to remember about home air filters is to change them regularly.
standard 1" depth fiberglass
filters should be changed every 30 days
and 1" depth pleated filters every
90 days. The filter life of a 2"
and 4" depth filter is 4-6 months
as they have more surface area to
collect dust particles.
However, recommendations vary based on a number of factors: the type of filter that you use, how many pets you have, whether anyone in your home has allergies, etc.
It is recommend that you run your system fan continually for better air cleaning performance from your air filter. The air filter can only clean air that circulates through it.

1/2" smaller than your filter
