URGENT: Medical Device Recall

Philips-Respironics CPAP and Bi-Level PAP Devices

Sound Abatement Foam - Susceptibility to Degradation and Volatile Organic Compound Emission

Immediate Actions

Immediate Actions to be taken by the User (per Phillips-Respironics):

  1. Discontinue use of your device and work with your physician or Durable Medical Equipment (DME) provider to determine the most appropriate options for continued treatment. To continue use of your device due to lack of alternatives, consult with your physician to determine if the benefit of continuing therapy with your device outweighs the risks identified in this letter.
  2. Register your device on the recall website
    1. The website provides you current information on the status of the recall and how to receive permanent corrective action to address the two (2) issues.
    2. The website also provides you instructions on how to locate your device Serial Number and will guide you through the registration process.
    3. Call 1-877-907-7508 if you cannot visit the website or do not have internet access.
    4. Patients who have already registered their recalled machine with Philips can check the status of their recall at the Philips Recall Portal

Additional Actions

  1. Purchase an in-line antibacterial filter (search for "antibacterial filter for cpap" on Amazon or another site) to catch any and all foam particles. Note that this will do nothing for the off-gassing.
  2. Purchase a new non-affected CPAP that is the equivalent or upgrade of your current machine. It appears that at least some insurance companies are allowing replacement prior to the 5-year lifetime. We suggest patients call and ask, as they likely will need a prescription and possibly a justification (the Do NOT use Recall) note from your doctor.
  3. Philips is recommending that customers and patients do not use ozone-related cleaning products.
  4. For questions please ask on the Apnea Board forum.

What others are doing

  • using an in-line antibacterial filter as a stopgap fix
  • purchasing, out of pocket, a competing product, often a ResMed device
  • registering with Philips-Respironics Recall list
  • calling their Doctor, DME, and insurance company to evaluate options
  • some patients are attempting to 'de-foam' their DreamStation products (there have been reported failures and successes)

Refurbished Machines

At this time, short of disassembly, we know of no way of determining if a PR machine (such as DS1) has been repaired by PR by replacing by the foam. Replaced foam is white, not gray/black.


No 'official' has said to de-foam the recalled devices. This includes Philips Respironics, FDA, Doctors Associations, etc. The "de-foaming" movement is purely a user movement. Users basically saying it is taking too long to get devices replaced or repaired, most estimates state a year to complete. Below are two threads on Apnea Board forums that discuss defoaming of the affected machines. Do so at your own risk.

Wiki Editor comments

Most likely a patient's apnea is severe enough that they would require continued treatment. An immediate response from Philips-Respironics in the form of a new machine or an immediate repair or replacement of the foam is not expected; therefore patients should take action to correct the situation.

Potential Replacement Devices

Philips-Respironics ResMed
  • ResMed AirSense 10 Elite (CPAP Mode only)
  • ResMed AirSense 10 AutoSet or AutoSet for Her (APAP) (Most recommend one of the AutoSets as they can also operate in CPAP mode)
DreamStation Go
  • ResMed AirMini AutoSet (Not compatible with OSCAR)
DreamStation ST
  • ResMed AirCurve 10 ST
DreamStation AVAPS
  • Example
DreamStation ASV
  • ResMed AirCurve 10 ASV


April 26, 2021 - potential health risks

Philips advised of potential health risks related to sound abatement foam used in specific Philips Continuous Positive Airway Pressure (CPAP), Bi-Level Positive Airway Pressure (BiLevel PAP) devices, and Mechanical Ventilators.

Possible health risks include exposure to degraded sound abatement foam, for example caused by unapproved cleaning methods such as ozone, and exposure to chemical emissions from the foam material. High heat and high humidity environments may also contribute to foam degradation in certain regions.

June 14, 2021 - Recall

As a result of extensive ongoing analysis following this announcement, on June 14, 2021, the company issued a recall notification (U.S. only) / field safety notice (Outside of U.S.) for specific affected devices.

June 23, 2021 - Health Canada posted a recall for the same products.

June 30, 2021 - FDA Safety Communication

Supplemental clinical information for physicians and providers for specific CPAP, Bi-Level PAP, and mechanical ventilator devices
This includes information on

  1. Foam degradation and
  2. Chemical emissions from the PE-PUR foam

July 9, 2021 - Canadian Response

From CTV news (in Canada): In July, the Canadian Thoracic Society, Canadian Sleep Society and the Canadian Society of Respiratory Therapists released a joint statement on the recall to help guide physicians, where they noted that “globally, the number of units affected is in the millions.” The included link is

In brief, after discussion with their doctor, most patients should continue using the machine until it can be replaced with an unaffected machine, preferably sooner than later.

This document contains guidance from medical teams on what to do in the immediate future.

July 14, 2021 - ResMed Response
Information regarding Philips' recall

A message from ResMed's CEO:
At ResMed, the leading global manufacturer in sleep apnea therapy, we know that ongoing treatment is critical to the health and wellbeing of many millions of people around the world. In light of Philips’ recent recall and field safety notices for many of its sleep and respiratory care products, I want to reassure our patients, providers, physicians, and communities that ResMed devices are safe to use and are not subject to Philips’ recall. ResMed devices use a different material than what Philips uses in their recalled machines. Patient safety is always our ResMed team’s top priority.
We rigorously test our devices against applicable standards before we launch a new product. We reevaluate our testing when other device makers raise concerns. The information we’ve reviewed from Philips’ recall of its devices and our detailed analysis of our products’ test results confirm that ResMed devices are safe to use.
At this time of considerable increase in demand for ResMed products, we are doing everything we can to increase our manufacturing of sleep and respiratory care devices, so we can get them to the patients who need them most. We will continue working closely and communicating directly with our customers and suppliers to help serve patients worldwide.

CEO, ResMed

August 10, 2021 - DMEs reporting Philips to begin distributing Recall Replacements

Several DMEs have acknowledged receiving this notification. It is the first positive sign on the recall, nothing more.

Dreamstation replacements will begin shipping soon

UPDATE 8/10/2021

After 8 weeks we have finally received additional information regarding the Phillips/Respironics CPAP and BiPAP recall. Phillips is planning to start shipping their first wave of replacement CPAP devices within the next 7 business days. We have not yet been notified as to who will be receiving them or how long it will take to mitigate all the affected devices. However, if you are one of the individuals who will be receiving a device in the first wave of replacement units, you will be notified directly by Phillips and given additional information on how to complete the process. Philips will have multiple waves of replacements that will happen over time and in each case you will be contacted directly by Philips with instructions on what to do.
