The CPAP Shop Discount Codes in September 2026

You get up to 75 nights to test a CPAP mask at home, and if it doesn't feel right, you can trade it for a different style or size. Buying a mask online is a bit of a gamble, since you can't try it on first. A mask has to seal against your face while you sleep, and no two faces are quite the same, so one that looks fine on screen can still let air escape, dig into your skin, or feel too tight in bed. Normally that means giving up and buying another one, but the trial lets you trade it in instead. You only pay for the mask you keep. If the new one costs more, you cover the difference, and if it costs less, you don't lose the gap.

How the timing works:

• A mask you've opened and used can be traded for a different mask or size within 75 days of buying it.

• After your first swap, a fresh 30-day window starts, so there's still time to dial in the fit if the second mask isn't quite right either.

• A mask you never opened can be returned within 75 days of the ship date.

Before you open anything, though, know that the trial covers the mask itself and not the smaller pieces that go with it. Cushions, pillows, headgear, and frames are the parts you'd normally replace over time, and once those are opened, they can't go back. Leave them sealed unless you're sure you need them.

One more step can save you the trade altogether. Run your pick through the store's virtual fit tool before ordering. It matches a mask to your face and sleep style in about two minutes, which beats mailing one back later.

Perk Points is a free rewards program that gives you points back on every CPAP order, which you can then use for money off future purchases. Masks, cushions, filters, and tubing wear out and need replacing on a schedule to keep your therapy working. You're going to reorder them regardless, so the points are essentially cash back on spending you couldn't skip anyway.

You earn $1 for every $40 spent, or about 2.5% back, plus a few points just for registering and for your first newsletter signup. That rate is small on any single order. What makes it add up is that points never expire, so each reorder quietly builds on the last with no deadline hanging over you. You redeem them at checkout toward your total, and members also get access to sales that guests don't see.

This makes the most sense for anyone restocking supplies on a regular schedule, since the rewards just keep building in the background for free. For a true one-time purchase where you'd rather not bother with an account, the math is thin, since 2.5% back on one order won't add up to much before you're done.

Adding a coupon code at The CPAP Shop is quick, as long as you know which discounts can be combined and which can't.

One heads-up before you start. A CPAP machine or a full mask system counts as a medical device, so The CPAP Shop needs a valid doctor's prescription on file before it can complete the order. Have yours ready to upload, since the order won't go through, discount and all, until it's there.

Here's the full path:

• Add your machine, mask, or supplies to the cart and start checkout.

• Scroll past Account Information and Shipping Address to reach the Apply Coupon Code section.

• Paste one code into the Discount Code field and click Apply.

• Check that the discount line shows on the Order Summary before you submit payment.

You can only use one coupon code per order, since the field takes a single code at a time. Gift cards are the one exception that does stack. The Apply Gift Card field sits right below the coupon field, so a gift card balance can ride alongside a code on the same order.

New to ID.me? You can verify right from the checkout sidebar under "Verification by ID.me" using the Responder, Military, or Nurse buttons. It's a one-time step, and future orders recognize your wallet and apply the discount on their own.

When a code won't apply, check the Discount Code field for extra spaces first. Next, confirm the item isn't already on a store-wide sale, since sale prices usually block stacking. If it still won't take, try a different code from the list. And remember that codes tied to a category, like masks, machines, or cleaning supplies, only work when your cart matches.
