Our 14x25x2 air filters keep contaminants and harmful particles out of the air. This 14x25x2 filter works by letting air pass through the media. Then, the media catches things like pet dander and dust while preventing them from entering the air supply. We have 14x25x2 air filters that have 100 percent synthetic, non-woven proprietary medias that are perfect for particle capture. What’s more, some of the 14x25x2 air filters have a pleated design meant to maximize efficiency and DHC. The frames are also heavy-duty and bonded to the media for extra security. Some frames are ecologically friendly, too. As always, we offer free shipping on all orders.
