Buyer's Guide - How To Buy A CPAP Mask

Welcome to the buyer’s guide for CPAP Masks. This short introduction to CPAP Masks should help you understand how to buy a CPAP mask, the differences between CPAP masks and interface styles, and the major manufacturers involved.

Styles of CPAP Mask Interfaces

There are five basic types of CPAP masks:
  • Example of a Standard Nasal CPAP MaskStandard Nasal CPAP Masks - The most popular style, this mask type covers only the nose during therapy. A silicone or gel cushion surrounds the nose and CPAP is delivered via the nostrils. Direct air is not delivered to the nostrils, instead a balloon of pressure is created all around the nose. Most patients find this mask type to be the easiest and most comfortable.
  • Full Face CPAP Masks - This style is becoming more popular because fitting is so much easier. A Full Face CPAP mask envelopes both the nose and the mouth of the patient. Perfect for mouth breathers, CPAP can be delivered via either the nose or mouth or both at the same time. This interface style is also popular as a backup mask for patients when nasal congestion is an issue.
  • Nasal Interface (Pillow Style) CPAP Masks - The Nasal Interface delivers CPAP directly into the nostrils of the patient. No surrounding mask parts cover the nose or mouth. This is one of the best CPAP masks for side sleepers, and it works really well with low pressures.
  • Oral CPAP Masks - The Oral interface is just that, oral only. CPAP is delivered only via the mouth and no interface to the nostrils is present. Very popular among mouth breathers who can not or choose not to use a chinstrap to keep the mouth closed.
  • Hybrid CPAP Masks - The hybrid masks were developed to bring together the ease of a full face mask with the delivery of a nasal interface mask. Hybrid masks deliver CPAP to both the mouth and directly to the nostrils, whereas a full face mask would deliver CPAP to the mouth and entire nose.

Do I Need A Prescription?

Whether you just started CPAP therapy or you are a veteran, you should know that all CPAP Machines and CPAP Masks, from any online vendor, require a prescription. Our Prescription Policy is pretty simple. Prescriptions can be faxed to us at 1-804-271-4715, or emailed to We accept scanned copies, photocopies, and even pictures from your cell phone or camera.

How Do I Know My size?

Example of a nasal interface CPAP maskIf this is your first CPAP mask, we suggest purchasing a mask that includes multiple sizes. You can then experiment with the sizes to determine which CPAP mask is best for you. We offer a whole category of COMBO PACKS that includes masks with multiple size cushions in the package. When replacing parts or getting a new mask in time, you will know your size for that particular mask and can buy the exact size. Also, sizing guides are available on most CPAP masks product pages, in PDF format. The sizing guides can be downloaded, printed, and used as an estimate of your size.

If you already have a CPAP mask, you can normally find the size of the current mask on the bottom of the cushion. Some descriptor should be present on the cushion to notate size such as a letter or a part number.

We also can try to determine your size over the phone. We will ask about your facial characteristics, your physical characteristics, and your bedtime routine and sleep habits. Some masks are better for those patients who like to read in bed while adjusting to the ramp pressure of the machine, some are better for wider noses, some are better for side sleepers or stomach sleepers. We are here to guide you through that process and can usually determine the best fit for you.
