With the CPAP Comfort Pillow Replacement Cover, you’ll always have a clean cover handy while the other cover is in the wash. This replacement is the same style cover that came with your CPAP Pillow. It features dual sides, so you can choose your favorite side for sleeping — the 3-D mesh side (for cool breathability) or the fiberfill side (for a soft, traditional feel). Includes a built-in tether to reduce hose drop.
