12x30x1 Air Filters

One of the hard-to-find air filter sizes is 12x30x1. While you do not normally find these available in stores, we have several options for you to look at. Our Filter Comparison Chart may be helpful in choosing the right level of air filtration. If this exact size does not work for you, we can make any custom size to fit your housing.
