*CONTRAINDICATIONS Masks with magnetic components are contraindicated for use by patients where they, or anyone in close physical contact while using the mask, have the following: • Active medical implants that interact with magnets (i.e., pacemakers, implantable cardioverter defibrillators (ICD), neurostimulators, cerebrospinal fluid (CSF) shunts, insulin/infusion pumps) • Metallic implants/objects containing ferromagnetic material (i.e., aneurysm clips/flow disruption devices, embolic coils, stents, valves, electrodes, implants to restore hearing or balance with implanted magnets, ocular implants, metallic splinters in the eye) WARNING Keep the mask magnets at a safe distance of at least 6 inches (150 mm) away from implants or medical devices that may be adversely affected by magnetic interference. This warning applies to you or anyone in close physical contact with your mask. The magnets are in the frame and lower headgear clips, with a magnetic field strength of up to 400mT. When worn, they connect to secure the mask but may inadvertently detach while asleep. Implants/medical devices, including those listed within contraindications, may be adversely affected if they change function under external magnetic fields or contain ferromagnetic materials that attract/repel to magnetic fields (some metallic implants, e.g., contact lenses with metal, dental implants, metallic cranial plates, screws, burr hole covers, and bone substitute devices). Consult your physician and manufacturer of your implant / other medical device for information on the potential adverse effects of magnetic fields.

**The mask contains magnets that may interfere with certain implants or medical devices. Please refer to the User Guide for complete information, including magnet contraindications and warnings.

Cleaning & Replacing Guidelines


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 properlyis 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!


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!


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.


  • 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!

Check out our blog on choosing the right CPAP cleaner for you, and visit our wide variety of CPAP cleaning machines now.

The health and safety of our patients is our top priority. We hope these tips are helpful, and we thank you for being a valued addition in our CPAP care community.
