DetailsLennox X6673 MERV 11 Pleated Filter - 20" x 25" x 5"
This filter is a brand new genuine Lennox X6673 air filter for the Lennox HCC20-28 Air Cleaner. The X6673 MERV 11 filter is 98% effective in capturing particles as small as 1 micron which includes dust mites, pollen and mold spores.
If you or anyone in your family suffers from allergies or other respiratory irritants, this filter is very good at eliminating those particles from the indoor air, and will help keep you and your family happy and healthy.
By using this filter, you also ensure that your system has clean air flowing through it which protects the performance, efficiency and effectiveness of your heating and cooling.
Be cautious when purchasing other than a genuine Lennox replacement filter. The Lennox X6673 has an actual dimension of 19 5/8" x 24 5/8" x 4 1/4", whereas aftermarket and generic filters do not meet these exact measurements, resulting in a filter which may not seal properly or impact its ability to remove airborne particles effectively. Lennox recommends this filter be replaced every 9 to 12 months in order to achieve the best results from your cabinet, depending on the condition of the environment it is servicing.
MERV (Minimum Efficiency Reporting Value) is the standard to which the filtering effectiveness of the media is measured. The higher the MERV number, the better filtration and smaller the particles it will remove.
