*Money Saving 3-Pack* When you order this product, you will save $3.00 off of the normal retail filter price. You will receive 3 genuine Carrier/Bryant replacement water panel evaporator 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 every month but is rated to last up to one heating season under normal operating conditions. Save $3.00 when you purchase the three pack.
