If firmer masks leave you with red marks and sore spots, the ComfortGel Blue takes a softer approach. Its blue gel cushion molds to your face, and you can even warm it in your hand first, while a thin silicone flap over the gel seals without you having to crank the straps.

An adjustable forehead support spreads the pressure for a steady, comfortable fit, and the quiet swivel elbow keeps air off your bed partner. We pair it with the React Health G3 X, which adjusts your pressure breath by breath, humidifier included.

Returns Policy

Warm the gel cushion in your hand for one to two minutes before fitting. The softened gel conforms to your face more easily and helps achieve a seal with lighter headgear tension.
Fit the mask lying down in your sleep position. The SST silicone flap seats itself under therapy pressure, so let the machine reach working pressure before deciding whether the seal feels right.
Adjust the forehead support height so it rests comfortably on your forehead without pressing down. A well-positioned forehead support takes pressure off the nasal bridge and reduces red marks.
If you wake with leaks, check the forehead support height and headgear tension before tightening straps. The SST flap is designed to seal under normal tension: overtightening usually makes cushion distortion and leaks worse.
The ComfortGel Blue is for nasal breathers only. If you breathe through your mouth or wake with a dry mouth, add a chin strap to keep your mouth closed during the night.
Rinse the gel cushion, frame, forehead support, and headgear daily with warm water and mild soap. Avoid alcohol-based cleaners on the gel, which can shorten cushion life.
Let all mask parts air dry completely before reassembly. Assembling damp parts can trap moisture inside the cushion and accelerate gel degradation.
Replace the gel cushion every 1 to 3 months or sooner if you notice persistent leaks, visible wear, or loss of softness. Replacement cushions and headgear are sold separately.
The four-point headgear adjusts with hook-and-loop tabs on both sides. Set each side independently so the mask sits level across your face, with the forehead support making even contact.
Use distilled water only in the humidifier, and clean with approved CPAP cleaning supplies (avoid ozone cleaners, which void the warranty).
Replace the reusable air filter about every 6 months, and the optional ultra-fine filter about every 2 weeks.

CPAP Mask

Product Features

If the recent foam recalls left you wary, the G3 X is built without the internal sound-abatement foam, and React Health introduces it as the first standard-size foam-free PAP available in the U.S. It still runs quietly, around 28 dB(A) per the manufacturer, so it is easy to sleep next to.

You should not have to think about pressure settings. In auto mode, the Smart A feature reads your breathing over several nights and fine-tunes your range, so therapy stays comfortable as your needs change. Prefer a set pressure? It runs in fixed CPAP mode too.

Dry air is one of the most common reasons people give up on CPAP. This G4600 includes the integrated heated humidifier and heated tubing, so the air reaches you warm and you see less water buildup (rainout) in the hose. Use distilled water to keep the chamber clean.

A Soft Gel Cushion That Shapes to Your Face

The blue gel cushion is pliable by design. Hold it in your hand for a minute before fitting and it softens to your contours right away, so the seal feels personal rather than pushed on. A thin silicone flap over the gel does the sealing work, which means the gel stays genuinely soft all night instead of having to double as a gasket. You will not need to wake up and re-tighten straps.

Forehead Support That Keeps the Fit Steady

The height-adjustable forehead support spreads the mask weight across your forehead rather than letting it pivot at the nose bridge. Position it so it rests comfortably on your brow and the mask stays stable as you move through the night. This is what lets you sleep with lighter headgear tension without the seal drifting.

No Magnets, So Implant Wearers Can Use It Safely

The ComfortGel Blue has no magnets in any part of the frame, cushion, or headgear. The FDA precautionary guidance for magnetic mask closures near pacemakers, ICDs, cochlear implants, and other implanted devices does not apply to this mask. Confirm with your cardiologist before starting therapy.

Take the Pressure Off Your Nose Bridge

The height-adjustable forehead support distributes the mask load across your forehead instead of concentrating it at your nose bridge. Set it so it rests flat on your brow and you reduce or remove the red marks that come with masks anchored only at the nose.

No Foam to Worry About Breaking Down

The G3 X is the first standard-size PAP in the U.S. built without internal sound-abatement foam in the air path. You do not have to think about foam degradation over time. The machine delivers the same reliable therapy whether it is new or years into use.

Pressure That Adjusts Breath by Breath

The Smart A algorithm reads your breathing in real time and raises or lowers the pressure as needed throughout the night. You get the minimum pressure that keeps your airway open rather than a fixed setting that may be too high when you are sleeping well.

Warm, Humid Air That Reduces Dryness

The built-in heated humidifier and heated tubing warm the air before it reaches you, so dry throat and irritation are much less likely to wake you up. Everything runs through one integrated unit with no separate humidifier to attach.

Quiet Enough to Stop Being the Noise in the Room

The G3 X runs at under 28 dB(A). Most people find it blends into background noise and stops registering as a sound at all, which makes a real difference when you or your partner is a light sleeper.

Your Progress Syncs Automatically Over 4G

Built-in 4G sends your therapy data to the React Health Connect platform each night without any Wi-Fi setup. You can review your numbers in the app the next morning and share them with your care team without plugging anything in.

FAQs

The blue gel cushion is the padding layer: it softens under warmth and molds to the shape of your face. The thin silicone Sure Seal (SST) flap sits over the gel and handles the sealing. Separating padding from sealing means the gel stays comfortable without needing to be firm, and the silicone flap holds the seal without requiring overtightened headgear.

Yes. Holding the gel cushion in your hand for a minute or two before fitting softens it and helps it conform to your face contours during the break-in period. Some users also find the cushion molds more precisely after the first few nights of use as the gel responds to their individual face shape.

The ComfortGel Blue comes in Petite, Small, Medium, and Large. Philips Respironics provides a fit guide on its website to help you measure and select the right size. If you are between sizes, start with the smaller size and size up if you experience persistent leaks at the sides of the cushion.

The ComfortGel Blue suits nasal breathers who want a soft, moldable gel seal and a traditional forehead-support fit. It is a strong option for people who develop red marks or soreness from firmer silicone-only cushions. Mouth breathers need a chin strap to keep their mouth closed, or should consider a full-face mask instead.

Yes. The ComfortGel Blue contains no magnets in any component. The FDA precautionary guidance about magnetic mask closures near pacemakers, ICDs, cochlear implants, and similar implanted devices does not apply to this mask. Confirm with your cardiologist before starting therapy.

No, not without an accessory. The mask covers only the nose, so mouth breathing will break the seal. A chin strap can help keep your mouth closed if you breathe through your mouth occasionally. Consistent mouth breathers should consider a full-face or hybrid mask.

Rinse the gel cushion, frame, forehead support, and headgear daily with warm water and mild soap, then allow all parts to air dry before reassembly. Do not use alcohol-based cleaners on the gel cushion, as they can degrade the gel material over time. Follow the cleaning instructions in the Philips Respironics user guide.

Replace the gel cushion approximately every 1 to 3 months, or sooner if you notice persistent leaks, visible wear, or loss of softness. Headgear typically lasts 6 months under regular use. Both replacement parts are sold separately. The ComfortGel Blue carries the 90-day Philips manufacturer mask warranty.

Yes to both. The G3 X is a prescription device, so a valid Rx is required, and the bundle is FSA and HSA eligible. If your prescription has lapsed, we can help eligible U.S. residents renew it.

The React Health G3 X carries a 5-year machine warranty, and the mask carries its own manufacturer warranty, so the two are covered separately. The G3 X also meets FAA requirements (RTCA DO-160) for use during all phases of flight.

Foam-free means the G3 X has no internal sound-abatement foam in the air path. The user-replaceable intake filter is a separate part. The machine shares data over a built-in 4G cellular modem, so no Wi-Fi setup is needed.
