Important Notes & Precautions:
If you use a CPAP device:
-
It is possible to port your oxygen tubing into your CPAP mask and get the benefit of both therapies while you sleep. Many masks were designed to allow both therapies; however, if your mask does not have a port, you may need to connect your oxygen tubing to your CPAP tubing with an Oxygen Enrichment Adapter instead. The Oxygen Enrichment Adapter allows you to feed oxygen into your CPAP tubing using a special adapter to connect your oxygen tubing, allowing you to receive the benefits of both therapies.
-
You should turn the oxygen ON after the CPAP machine is already running. (Do not start the oxygen and then start the CPAP; the CPAP should always start first).
Other:
-
There are other precautions you need to follow when using oxygen. For instance, you should not smoke around an oxygen supply device, and you should also keep your device away from heat. Please refer to the user manual for important instructions.

Cleaning & Replacing Guidelines
THE ULTIMATE GUIDE TO REPLACING & CLEANING YOUR CPAP SUPPLIES
With cold & flu season and COVID-19 in full swing, it's more important than ever to focus on your health. Don’t know where to start? Start with your CPAP supplies. You use this equipment every night, so making sure it's being replaced and cleaned properly, is critical not only to your sleep health, but your overall health as well.
Did you know that the natural oils from your face stick to your cushion? Over time, this will soften your mask cushion and break down the seal. Unfortunately, you will then experience air leaks and a poorer night sleep. Do not let this happen to you!
We created the ultimate guide (as recommended by major insurance companies) to make sure you are replacing your CPAP supplies on time and cleaning them correctly!
WHEN SHOULD I REPLACE MY CPAP SUPPLIES?
See below for the insurance recommended schedule:
- Every 6 Months: Headgear, Black Non-Disposable Filter & Chinstrap
- Every 3 Months: Frame, Tubing
- Every Month: Full Face Mask Cushions
- Bi-Weekly: White Disposable Filters, Nasal Mask Cushions
- Only when cracked or broken: Humidifier Chamber
Failure to timely change your CPAP supplies could lead to infections and respiratory problems! There is hidden bacteria, grime, and dirt all over CPAP supplies!
HOW SHOULD I CLEAN MY CPAP SUPPLIES?
In-between new supplies, pollen, dust, bacteria, and air particles build up on your supplies. Manufacturers, suppliers, and sleep physicians all recommend regular cleanings of your CPAP equipment and supplies; but keeping track of when to clean what, is no easy task! We are here to help.
“It is vitally important to keep everything as clean as possible, as hoses/tubing and masks can be a prime breeding ground for bacteria and mold,” said Phoebe Ochman, director of Communications for Sleep Apnea Treatment Centers of America.
CLEANING YOUR CPAP SUPPLIES
- Add warm water to a bathtub or sink.
- Mix in a mild soap. Some patients prefer baby soap, the Neutralizing Pre-Wash by SoClean, or a 50/50 solution of water and white vinegar.
- Swirl around for a few minutes and then rinse thoroughly.
- Leave all items to hang/air dry. Be sure to dry the chamber as much as possible with a paper towel or cloth, and then leave it out to air dry the rest of the way.
- Clean all high-touch surfaces like nightstands, doorknobs, and light switches daily with a disposable wipe or a cloth and an EPA approved disinfectant.
Important Tips
- Do not use bleach or other harsh chemicals.
- Empty unused humidifier water daily and refill nightly.
- If distilled water is unavailable, a back-up chamber should be kept on hand to immediately replace if residue develops.
- If your mask has magnetic clips, leave them attached to the mask frame before cleaning.
Another option is to use a CPAP cleaning machine. It will save you time and energy for easy sanitizing and kill bacteria, germs, and other pathogens on your supplies. Let it do the hard work for you!
