Specifications:
Pool air pillow can create surface tension while relieves the pressure on the sides of pool due to freezing temperatures, so your pool won’t leak or crack. It will push your pool cover out of the water so water won’t freeze on your pool cover. And it will also reduce winter cover from excess rain, snow and leaves.
Note: Inflate the pool winter pillow to 60% to 70% of their capacity to allow compression. And please press the valve of the pool pillow tightly to avoid air leakage.
