PurFlow™ is a gliding pillow cover for more comfortable CPAP sleep. It lets your head turn without dragging your mask, so you get fewer leaks, fewer wake-ups, and less strap tension.
Why does your CPAP mask leak at night — even when it fits?
Because you move. You turn about 20 times a night, and a standard pillowcase grips your mask on every turn — dragging it out of position just enough to break the seal. Then comes the familiar chain: hissing air, tightening the straps, and red marks in the mirror by morning. If you sleep on your side, you likely know all three:
Mask drags
Air leaks
Strap marks

PurFlow™ absorbs the friction — so your skin and hair don't have to.
Wondering How PurFlow™ helps with your CPAP mask ?
Standard pillowcases grip your mask straps, dragging them out of place every time you turn over. PurFlow's glide layer lets your head move freely, without pulling your mask with it.

Real Questions, Real Comfort
Why does my CPAP mask shift or leak when I turn at night?
Most leaks aren't a mask problem — they're a pillow problem. A standard pillow surface drags against the mask every time you turn, breaking the seal. PurFlow's fluid layer moves with your head instead of against it, so the mask stays aligned through the night.
What's the most comfortable pillow setup for CPAP users?
Side sleepers in particular benefit from a surface that reduces friction against the mask and hose. PurFlow sits under your regular pillowcase and reduces the drag that causes strap marks and mid-night readjustments.
Will PurFlow work with my mask type?
PurFlow is a surface layer, not a mask replacement — it's designed to work under nasal, full-face, and nasal pillow masks alike, for any pillow you already use.
Does PurFlow help with strap marks or a sore face in the morning?
Reduced friction against the pillow means less mask drag overnight, which is the main driver of morning strap marks and pressure points for a lot of side sleepers.
Can PurFlow fit any pillowcase size?
Yes. PurFlow comes in two sizes, Queen and King, designed to fit seamlessly under any pillowcase without altering your room's aesthetic.
What is PurFlow made of, and what are the benefits?
PurFlow is crafted from our exclusive GlideTex fabric — a high-quality polyester engineered to minimize friction. It's soft, durable, antibacterial, and breathable.
