To maintain the efficiency of your home or business’s heating and cooling system requires changing the filter on a regular basis. At Merv Filters LLC, we manufacture a range of pleated air filters, made of electrostatically charged, 100% synthetic media that have a capability to capture airborne irritants, including pollen, dust, dust mites, and mold.
Our MERV 8 filter 19x20x4 has an open area of 96% and is unaffected by moisture. This filter media is resistant to a broad range of chemicals and will not support bacterial growth. The high strength enclosure frame utilizes double wall construction. Manufactured to last 90 days, which is better than fiberglass filter that lasts an average of 30 days.
We recommend replacing your system’s air filter more often as the older filter is, the less dirt is removed from the indoor air, resulting in polluted air quality and higher utility bills. Order online today and get it at your doorstep within 3-5 days. Feel free to contact our support team for any query regarding product size.
Important Note: When you search for MERV 8 air filters 19x20x4, you’ll likely to get 18.5×19.5×3.75 size filter. Nearly all our filters go by the nominal size, which is a bit greater than the actual size of the filter.
