Merv Filters LLC 20x20x1 MERV 8 furnace filters are effectively designed to remove about 85% of unwanted airborne particles and allergen irritants such as dust mites, pollen, mold spores, pet dander, dust and smog from your home or business space. Dirty filters will not only affect your health, but also reduce your system’s efficiency and therefore higher energy bills.
Our MERV 8 pleat filters provide the less airflow resistance with higher efficiency resulting in lower pressure drop allowing your heating and cooling systems to stay cleaner and run more efficiently. Our MERV 8 20x20x1 filters are offered in ASHRAE 52.1 and 52.2 ratings and have a capability to withstand in harsh conditions. Made with the electrostatically charged synthetic material that can draw allergens between 3 – 10 microns. With a larger surface area, our MERV 8 filters maximize dust holding capacity. Heavy-duty, moisture resistant beverage board is used as the enclosure frame for extra support.
These 20x20x1 MERV 8 air filters are constructed to last for up to 90 days. We recommend you to replace your HVAC filter every 30-60 days minimum, if you have anyone suffering from allergies or if pets are present, especially cats in your home.
Important Note: When you buy a 20x20x1 MERV 8 filter, measure the dimensions to make sure you find the right one. The nominal size doesn’t match with the actual size. If the nominal size of the filter is 20x20x1, its actual size is 19.5X19.5X0.75
