16x20x4 8 Air Filter - Box of 3   Actual Size of Filter: 15.5 x 19.5 x 3.625   Our goal is to provide the best air filters for every home. While pure air is always our goal, we know that some units are unable to use higher rating filters. So, we also offer 8 filters. Our 16x20x4 8 filters are the perfect filters for homes that have older units. Even though 8 filters are not as efficient as higher rating filters, they are still great filters. The initial efficiency of our 8 filters is 74.3% for particles 7.0 � 10.0 microns in size. Remember though, that is just the initial efficiency�after a few complete air changes, the 8 filter�s efficiency raises greatly. In areas where a lot of larger airborne particles are present, our 8 filters work ideally. Compared to cheap, fiberglass filters, 16x20x4 8 filters are a considerably better choice for healthier air. These filters are also electrostatically charged, which means the filter acts as a magnet for the larger airborne particles. Whether you are in the market for 16x20x4 8 filters or just looking for simple tools to aide you in purifying the air in your home, Water Filters wants to be the solution for all your clean air needs. We offer a wide variety of different filter sizes!
