AFB Bronze MERV 6 20x23x1 Pleated AC Furnace Air Filter. Pack of 4 Filters. 100% produced in the USA.

The AFB Bronze filter by AirFilterBuy is a step up from a standard fiberglass filter. It is designed for everyday home use and removes dust mites and debris from the air. Whenever you are choosing an air filter, make sure that you compare the nominal and actual size of the furnace filter that you are replacing. In this case, the ‘nominal’ size of the filter is 20x23x1 while the ‘actual’ size of the filter is 19.5 x 22.5. Generally, the nominal size is rounded and in bigger print while the actual size is in smaller print and in parenthesis to the side.

The AFB Bronze filter is designed to last 3 months, or 3 times the average fiberglass filter. The filters ship directly from the manufacturer to your doorstep, allowing AFB the ability to offer a premium product at a reasonable price.

Each quantity purchased is for a pack of 4 filters.
