Specifications

What is MERV? MERV means Minimum Efficiency Reporting Value which was developed by the American Society of Heating, Refrigeration and Air Conditioner Engineers, ASHRAE. The higher the MERV rating the more efficient the filter will be at capturing airborne particles. Please check with your HVAC specialist as to what MERV rating is best for your system.

What is the MERV rating of Carbon filters? The main use of the Carbon filter is to remove odors from the air. The filters are made with a carbon impregnated media and are not electrostatically charged. The Carbon filter does not have a MERV rating. If you want to remove odors such as cigarette smoke or cooking fumes then the Carbon filter is perfect for you. If you are wanting the best filtration possible then choose a MERV rated filter, remember the higher the MERV, the best the filtration!

FAQ

What does Aftermarket mean? Aftermarket means the filter is not a name brand filter, or OEM. However, the aftermarket filter is built to the same specifications as the Original, name brand filter. While it might not look exactly like the Original filter, it should fit and work just like the Original. It is a low cost alternative!

What is Nominal Size and Actual Size? Nominal Size is the advertised or listed size of a filter. This is usually printed on the filter and a whole number, like 20x25x6. However, most of the time the filter will measure something different, the Actual Size. Actual Size is the true, measured size of a filter. If it is printed on the filter is will be in parenthesis or in smaller font. The Actual Size is typically a fraction like 19 ¾ x 24 ¼ x 6 3/8. ***When purchasing a filter, be sure you are getting the correct Actual Size. Often times there is more than one actual size to nominal size.***
