Product Overview

Get mask wipes for just more when you add this item to your cart.

Mask assembly kits are a way to refresh your mask without purchasing an entire mask and headgear.

The next generation Quattro is modest in appearance, covering less of the face than most masks. The Quattro FX focuses on compliance through comfort by using a suspension-like frame that eliminates the forehead support. Technology like the Spring Air cushion and Swing Seal fitting technique help make the Quattro FX quick and easy to adjust.

Manufactured by ResMed.

Product Features

The Quattro FX Full Face Mask was designed with comfort in mind. The mask provides a clear line of sight by eliminating the need for a forehead support. Spring Air technology enables the mask to flex when the cushion is inflated around the bridge of the nose. The Spring Air reflexes to head movement and helps maintain the seal.

Some of the best features from the original Quattro have carried over. The Quattro still includes:

  • Built-in vent design for dispersing exhaled carbon dioxide
  • 360 degree elbow rotation
  • Tube Swivel
  • Set-and-forget headgear clips

Fewer Contact Points

The overall design of the Quattro FX helps to create a secure seal without the aid of a forehead support. Eliminating the forehead support means fewer points of failure and an end to red marks on your forehead. Without a forehead support, you will also enjoy a clear line of sight for viewing television or reading a good book in bed.

Spring Air Technology

Spring Air technology helps to create a suspension-like action between the Spring frame and Spring Air cushion. These two mask parts, along with the contoured crown cap headgear, work together to offer an angular adjustment that makes a forehead support obsolete. The stability of the design helps to distribute pressure evenly around the face, yet reacts to accommodate user movement.

Dual-Wall, Spring Air Cushion

The Mirage series of CPAP masks have endeavored to provide superior cushion design through the incorporation of two cushion layers. The dual-walls consists of an inner, supportive layer that stabilizes the cushion and a softer, outer membrane that reduces the likelihood of leaks and pressure sores. As air flows through the cushion, the outer membrane rolls and inflates around the nose rather than stretching over it.

Swing Seal Technique

Size. Swing. Seal. Those are the simple steps used for fitting the Quattro FX. The Swing Technique is the result of the Spring Air technology and the dual-wall membrane that surrounds the bridge of your nose. As air flows through the mask and into the cushion, the contoured membrane inflates and gently positions the cushion against the face so that it forms a secure seal without the need to over tighten the headgear.

This unique design makes fitting a breeze. With the headgear clips removed, just position the mask at an angle, so that the cushion rests on the middle of the nasal bridge. Then swing the mask down to rest between the bottom lip and chin. Reattach the headgear clips and adjust the side straps for a snug fit.

This package DOES NOT include Headgear. Headgear can be purchased separately here or along with the mask here.

Important Tips

Where do I find the size?

To find the size of the mask frame, turn the mask upside down. The flat bottom of the mask frame and mask cushion needs to face the user. The size is embossed between the ports cap and the edge of the mask frame. A clear letter will indicate the size of the mask frame.

The size of the full face cushion is located on the flat bottom of the cushion. Turn the mask upside down with the headgear facing away from the user. Located on the bottom silicone flap to the right side of the name of the mask, an embossed clear letter will specify the size of the full face cushion. The letter is larger than the word ResMed and Quattro™ FX.

Quattro and Quattro FX mask frames, cushion clips and cushions are NOT interchangeable. Individual cushions are NOT interchangeable within each mask. The size must correspond for the mask to work properly. For more information visit the Mirage Quattro FX Full Face Mask Cushion and Clip.

Sizing Help

The Mirage Quattro sizes DO NOT match up directly with the Quattro FX sizes. The Quattro FX sizes are a bit smaller than the Mirage Quattro sizes.

To get a more accurate idea of your size, measure from the top of the bridge of your nose down to the place in between your bottom lip and chin. View the images below to see where on the face to measure. Compare your measurement with the size measurements here:

  • Small: 3 9/16"
  • Medium: 4"
  • Large: 4 3/8"

How do I care for my mask?

Masks should be washed daily with warm water and gentle soap or baby shampoo. Let the mask air dry. Never use antibacterial soap as it will break down the silicone of the mask cushion. Avoid soaps that include lotion which can coat the mask and cause it to lose its seal. A safe cleaner is the Control III Disinfectant CPAP Cleaning Solution. Remember, going to bed with a clean face will improve your seal and protect the lifespan of your mask. Citrus Mask Wipes

The best time to clean your mask is in the morning after use. This removes the oils left behind from your skin which can reduce the lifespan of your mask. We recommend using Mask Wipes to make daily morning cleaning easy. The mask wipes are made from materials that will not break down your mask.

Citrus Mask Wipes

For customers who want to completely disinfect their mask and accessories, there's an even better option than wipes. The Lumin Mask and Accessories Cleaner uses powerful UV light to disinfect, killing almost all bacteria almost instantly. It's not a cleaner and doesn't scrub or wash anything, but for simple disinfecting the Lumin works great!

Here are some other cleaning products to help with keeping your mask fresh:

How often should I replace my mask?
Medicare allows for mask cushion replacement every three (3) months, and a complete mask system replacement every six (6) months. CPAP manufacturers and vendors suggest these replacement schedules as well.

In our experience, most mask cushions begin to deteriorate after about six months of use. The cushion eventually becomes too soft to hold a seal. The headgear straps lose elasticity and must be tightened more and more to get the same quality seal.

We strongly suggest replacing cushions and pillows as soon as they start to soften. Air leaks may reduce the effectiveness of CPAP therapy and headgear that is too tight may cause facial sores at pressure points. In most cases, replacement headgear is available if it is stretched out or the Velcro worn out.

To see what parts of your mask are replaceable refer to our Replacement Part Finder. Just search for your mask to see all of the replaceable parts.
What does a mask prescription need to say?
A mask prescription must contain all of the following information:
  • One of the following words or phrases: "CPAP Mask", "CPAP Supplies", "CPAP Humidifier", "CPAP", "Continuous Positive Airway Pressure", "APAP", "AutoPAP", "AutoSet", "Auto CPAP", "Auto Adjusting CPAP", "Self Adjusting CPAP", "BiPAP", "BiLevel", "VPAP", "BiPAP Auto", "BiPAP ST", "Synchrony ST", "VPAP ST"
  • Your physician's contact information
  • Your physician's signature
  • The patient's full name

Why might I need a full face mask?
If your mouth drops open during sleep, a full face may be selected to allow for the CPAP airflow to be delivered through both the nose and mouth.

Some CPAP users move to using a full face mask after finding that using a nasal mask along with a chinstrap does not meet their sleep therapy needs. Some CPAP users use a full face mask when suffering from seasonal allergies.
