Frequently Asked Questions
Minimum Efficiency Reporting Value (MERV) is a filter industry standard system that rates the overall effectiveness of air filters. Higher value MERV rating equates to finer filtration, meaning fewer dust particles and other airborne contaminants can pass through the filter. Other common ratings found within certain brands and stores includes FPR, MPR. They all follow the same basic principal, the higher the number the greater overall effectiveness of the air filter.
Choosing the correctly sized air filter is important in order to keep air clean in your home. An improperly sized filter may have limited performance. Determining the proper air filter size can be confusing, since filter packages generally display two sets of dimensions. It is important to understand that these dimension sets are the nominal and actual dimensions of the filter, and differences between the two.

No spaces, fractions only 1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 7/8.
Most often there will be an arrow on the side of the filter which will indicate which way to insert the filter. The arrow will show which direction the air is to travel through the filter. If there is no arrow the filter can be installed in both directions.
Remember your filter is designed to protect your system first and foremost. Air should be traveling through the filter before your blower and system.
Furnace, AC and HVAC filters are most often measured in inches. A nominal measurement would be a rounded number like 20x25x1, rounded up to the nearest inch. These filters if measured with a tape measure would likely be closer to 19 ½" x 24 ½" x ¾" which would be the actual true exact size.
