We offer genuine Carrier/Bryant replacement filters. The filter is aluminum with a metal frame and distributor that fits on the top of the filter. The filter is coated with a powdery substance that allows the water to move more slowly over the filter thereby permitting more water to be absorbed into the air. This filter should be inspected bi-monthly but is rated to last up to one heating season under normal operating conditions. For additional savings, we offer this product in a 3-Pack. (See listing at bottom of this page.)
