An air pillow is a must have this winter pool season to ensure that debris does not collect on your winter pool cover and stress or cause damage to your pool walls. In addition an air pillow will absorb freezing water so that the pressure of freezing water does not affect your pool walls. Reduce excess rain, snow, leafs and wind swept debris from your above ground pool and off your winter pool cover this winter season. Simply inflate the air pillow and center in your pool once the water is below your skimmer/return line and prior to putting the winter cover on for the season. Please select air pillow size from the drop down menu below.
