          With MERV 8, 11, and 13 to choose from on the perfect fit 20x25x4 air filters, you are guaranteed to find the air quality you need at a price that accommodates your budget. Some families only need a MERV 8 rating. This type of filter removes pet dander, mold, dust, pollen, and lint, alleviating allergy symptoms associated with the like; however, MERV 11 adds one more pollutant to the list – auto emissions. MERV 13, on the other hand, goes a few steps further by trapping very fine dust, smoke, and bacteria. What is it that you need from your 20x25x4 furnace filter? In addition to this option, we provide convenience in the filter-buying process.
