20x25x5 Lennox Replacement Air Filters MERV 10 Qty 1 Made in USA

20x25x5 Lennox Replacement Air Filters MERV 10 Qty 1 - Made in USA

• Made to replace Lennox X6673 in Units Prior to 2013. This also replaces the Filtrete DP03DC filter.

Actual Size of Air Filter: 19 7/8" x 24 7/8" x 4 3/8"

IMPORTANT Note: Air filters have an actual size that is a fraction of an inch smaller than the standard size (also known as "nominal size"). The size printed on your air filter may NOT be the Actual Size. With the 4" and 5" air filters there is a wider variance between the nominal size and actual size for the different manufacturers. Because of this, the air filter you are replacing could be called a 20x25x4 and really be the same as our 20x25x5. This is why we ask you to measure your air filter so you aren't surprised if the air filter doesn't fit!

Nordic Pure manufactures MERVs 7, 8, 9, 10, 11, 12, 13, 14, and 15 high efficiency pleated air conditioner and furnace filters. They capture microscopic airborne dust, pollen, allergens, mold spores, pet dander, bacteria and particulates carrying bacteria, and viruses in the air. Our MERVs 12, 13, 14, and 15 air filters, which capture more airborne particles, are best for people suffering with allergies and other breathing issues.

Our non-woven synthetic air filter media will not support the growth of mold or bacteria, keeping your home healthier. As we say in the industry, "You have to move the air to clean the air". Our hypoallergenic and antimicrobial air filters use permanently electrostatically charged material that acts like a magnet to help dust cling to the air filter. This helps protect your unit, home, and family.

You may be able to use our standard 20x25x4, which is 19 1/2 x 24 1/2 x 3 5/8. Or, you might need an Air Bear 20x25x5 replacement filter, which is 19 5/8" X 24 1/8" X 4 7/8", instead of this Honeywell/Lennox replacement filter, which is 19 7/8" x 24 7/8" x 4 3/8". The nominal size is the same, but the actual dimensions are different. Just check the measurement, "Actual Size", before ordering.
