CPAP Mask Fit Pack vs. Buying a Single Size: How to Stop Returning Masks
You did the hard part. You figured out whether you sleep better with a nasal mask, nasal pillows, or a full-face mask. You ordered a Medium. And it still leaks across the bridge of your nose, digs into your cheeks, or slips off at 3 a.m. So back it goes — and you start over with a Large.
If that return-and-reorder loop sounds familiar, here is the part most people miss: the problem usually is not the brand or the model. It is the size. And there is a simple way to skip the whole cycle.
In short
- The #1 reason CPAP masks get returned is the wrong cushion size — not the wrong brand or the wrong mask style.
- A fit pack (also called an all-size kit or starter pack) ships the full range of cushion sizes for that mask in one box.
- You try each size, keep the one that seals, and skip the return-and-reorder cycle entirely.
- A fit pack usually costs about the same as a single mask — roughly $79–$129 — so you get every size for close to the price of guessing at one.
- Buy a fit pack if you are new to CPAP or unsure of your size. Buy a single size only if you already know your exact model and cushion size.
- At American Oxygen we stock fit packs from React Health (we are an authorized seller), plus genuine Fisher & Paykel, Philips Respironics, and AirFit / AirTouch masks — in nasal, nasal-pillow, and full-face styles.

Why the wrong size — not the wrong mask — is the real return
Two people with the same face shape can wear completely different cushion sizes. Nose width, the height of the nasal bridge, cheek fullness, and even how much you move at night all change which size seals for you. That is why “I wear a Medium in everything” does not hold up with CPAP cushions: sizing is not standardized across masks, so a Medium in one mask can seal like a Small in another.
When a cushion is too big, air escapes toward your eyes and the mask feels loose. Too small, and it presses red marks into your skin and still leaks. Either way the therapy feels worse — and the mask gets blamed and returned, when a different size of the same mask would have worked.
If you are still deciding between a nasal mask, nasal pillows, or a full-face mask in the first place, start with our companion guide: CPAP mask types: nasal vs. pillow vs. full-face. Then come back here to nail the size.
What is a CPAP mask fit pack?
A fit pack is the same mask you would buy normally — frame, headgear, and elbow — packaged with every cushion size the mask comes in instead of just one. Manufacturers use a few names for the same idea:
- All-Size Kit — React Health (Viva, Siesta)
- Fit Pack — Fisher & Paykel (Vitera, Solo, Evora) and Philips Respironics (DreamWear)
- Starter Pack — the AirFit and AirTouch line (N30i, P30i)
You open the box, fit the frame, then swap cushions until one seals cleanly with no leak and no pressure points. Keep that size. When it is time to replace a worn cushion months later, you already know your size and only reorder that one part — no guessing, no returns.
Fit pack vs. single size: which should you buy?
| Fit pack / all-size kit | Single size | |
|---|---|---|
| Best for | New CPAP users, first time with a mask style, anyone unsure of their size, buying for a family member | Experienced users who already know their exact model and cushion size |
| In the box | Mask + the full range of cushion sizes | Mask + one cushion size you choose |
| Return risk | Very low — you have every size in hand | Higher — a wrong guess means a return |
| Typical price | About the same as a single mask (~$79–$129) | Similar or slightly less |
| Reordering later | You know your size — reorder just the cushion | You know your size — reorder just the cushion |
The surprise for most buyers: a fit pack costs about the same as a single mask. You are not paying a premium for all the sizes — so unless you already know your exact fit, the fit pack is simply the lower-risk buy.

How to pick your size from the pack
Once your fit pack arrives, here is the simple way to lock in the right size — no tools, no measuring tape:
- Start one size down from what you would guess. Most people wear a smaller cushion than they expect.
- Fit it lying down, not standing up. Your face changes shape when you lie back, so size it in your real sleep position with the machine running.
- Tighten the headgear only until the leak stops — no further. A good seal comes from the right size, not from cranking the straps.
- Check for marks in the morning. Deep red pressure marks mean the cushion is too small; air blowing toward your eyes means it is too big.
- Keep the winner, store the rest. Now you know your size for every future reorder.

Already know your size? Buy the single cushion.
If you have used the same mask for a while and know your exact size, you do not need the fit pack — order the single-size mask or just the replacement cushion. For example, the AirFit F30i full-face mask lets you pick your size directly, and a worn cushion can be replaced on its own with an AirFit F30i replacement cushion for less than a new mask. Swapping the cushion every few months keeps the seal fresh without buying a whole new mask.

Frequently asked questions
What is a CPAP mask fit pack?
A fit pack is a CPAP mask that ships with every cushion size in one box instead of a single size. You try each size, keep the one that seals best, and set the others aside. Manufacturers also call it an all-size kit or a starter pack.
Does a fit pack cost more than a regular mask?
Usually not. Most fit packs cost about the same as a single mask — roughly $79 to $129 — so you get every size for close to the price of one. The current price is on each product page.
Why do so many CPAP masks get returned?
The most common reason is the wrong cushion size, not the wrong brand. Cushion sizing is not standardized across masks, so a Medium in one mask may seal like a Small in another. A fit pack removes the guesswork because you have every size in hand.
How do I know which cushion size fits?
Fit the mask lying down with the machine running, tighten the headgear only until the leak stops, and check for marks in the morning. Deep red marks mean it is too small; air toward the eyes means it is too big. This is about comfort and fit, not medical advice.
Which fit pack should a first-time CPAP user buy?
If you are new, start with the mask style that matches how you sleep — nasal, nasal pillows, or full-face — and buy that style as a fit pack so size is not a gamble. Our mask finder and our team can help you choose.
Are your masks genuine?
Yes. American Oxygen sells genuine masks from Fisher & Paykel and Philips Respironics, genuine AirFit and AirTouch masks, and we are an authorized seller of React Health (Viva and Siesta). Every fit pack ships new and sealed.
Can I just replace the cushion later instead of buying a new mask?
Yes. Once your fit pack tells you your size, you only need to reorder that cushion when it wears out. A replacement cushion costs less than a full mask and keeps the seal fresh.
