Lightweight CPAP Nasal Mask for Improved Fit and Comfort

Designed to improve comfort and provide uninterrupted sleep for you and your bed partner, the Fisher & Paykel Eson is an extremely quiet, lightweight mask.

Maintaining the Eson is easy thanks to its compact three-part design. Finding the right fit is also a breeze with three available sizes - Small, Medium, and Large.

We offer a 30 Day Mask Assurance program with all our masks to bring you worry-free online mask shopping. In the unfortunate event that your mask doesn't work for you, just give us a call to exchange it for a different size or a different mask. Please refer to our Mask Assurance page for full details.

RollFit Seal
Fisher & Paykel designed the Eson Nasal Mask so that it rolls on the bridge of your nose for increased comfort and a more precise fit. The RollFit Seal reduces the pressure on your nose and face by moving with you.

Ultra Quiet
The diffuser of the Fisher & Paykel Eson decreases exhalation noise by dispersing air away from you and your partner. The diffuser is held in place by the diffuser cover and can be easily replaced by unclipping the diffuser cover from the mask.

Eson Mask Cushion and Headgear Sizing
The Eson comes in sizes S (Small cushion & Small headgear), M (Medium cushion & M/L headgear), and L (Large cushion & M/L headgear).

Easy Fit Headgear
Made of breathable material to increase your comfort, the headgear employs conveniently located velcro straps for a personalized fit. The headgear is also easy to remove – simply unhook the clips from the mask frame and slide the headgear off your head.

Key Features

  • RollFit Technology. Adapts to your movement and reduces pressure points with the rolling technology on the bridge of the nose.
  • Ultra Quiet. The ultra-quiet exhalation diffuser reduces the noise on your Eson CPAP mask.
  • Ergonomic Headgear. Provides stability and a unique fit.

Reviewer’s Tip

Three adjustment points on the headgear allow you to customize the fit. The first is located on the crown of your head, the second is in front of your forehead, and the third is below your cheeks.

Start your headgear adjustments with the forehead straps, followed by the two straps below your cheeks. The forehead strap should rest horizontally on the forehead, just above the ears. You can tighten or loosen the crown strap to move the headgear further up or down on your head.


Can I buy replacement parts for the Eson?
Yes, we sell headgear, cushion, and diffuser replacements. Since silicone cushions soften over time, we recommend replacing the cushion every 3 months for optimal seal. The headgear should be replaced after 6 months or when you notice the fabric stretching out. The diffuser is not washable and should be changed every two to three months.

Does the Fisher & Paykel Eson Nasal Mask work with all CPAP machines?
Yes, the Eson Nasal Mask works with all CPAP machines with the exception of the ResMed AirMini. The Eson connects to all CPAP hoses with a standard 22 mm diameter connector cuff.

Great mask, I have no complaints. It’s nothing revolutionary but it does its job well and it’s comfortable and convenient.

This mask doesn’t feel obstructive at all, and it’s good for all sleeping styles (other than on your face). The tube elbow pivots so when I sleep on my back, the hose doesn’t have to sit on my body and my arm. There’s three points of adjustment too which means you should be able to adjust it to whatever feels comfortable to you. Just one note, the manufacturer advises you to only adjust the top of the head strap once and to use the forehead and cheek straps for day-to-day adjustments. I would advise you to make some further adjustments once you get in your sleeping position. Overall, the mask feels very lightweight and comfortable.

I get up a decent amount during the night to use the restroom (old age) so it’s pretty important that I can get disconnected without hassle. This mask doesn’t use magnet clasps but it does have a quick release clip on the right side which is very fast to get undone. However, I don’t even need to use it because I found you can just disconnect the main hose at the elbow part. Really fast and it means I don’t have to even take the mask off.

I haven’t detected any leakage problems and my AHI is as low as ever with this mask. Not much else to say on performance other than the noise seems to be good due to their “Q Cover� system.

Overall, I find this mask to be fantastic. It’s comfortable, convenient, efficient, and all at a great price. I would recommend you consider it too.

Subject: Well designed
This mask is design with two main focuses: seal of the cushion, and quietness of the air flow. It lives up to both of these and overall performs as a top notch mask. I can unequivocally recommend it to anyone looking for a nasal mask, and it’s become my favorite mask out of all the ones I’ve used before.

The cushion is designed where there’s a rigid plastic part nestled in a broader, flexible silicon seal. This can bend in all directions and flex, which is meant to conform to your face. What this means is that the part actually touching your face is able to form a perfect seal. Airflow is uninterrupted and the air is sealed up which means you don’t have leaks. I’ve found this to work great and I’ve been able to sleep night after night without discomfort, lines on my face, or leaks. Replacements are reasonably well priced too.

As for the noise, the mask has a sophisticated diffuser system called the Q cover. There’s an insert which helps diffuse the air and I’ve found that this the most quiet mask out of any mask I’ve used. Replacements for those are fairly priced too.

Finally, the headgear is nice. The material is breathable and easy to adjust, with sufficient holding points around the head. It also has clips on the bottom two straps which clip into the plastic portion. They’re easy to disconnect so you can get up and going very easily.

I bought this mask since it had such glowing reviews and after wearing this mask for a few weeks, I can give my full recommendation as well. This is definitely the lightest mask I’ve ever tried, it really seems like this mask is designed for maximum comfort and quality for minimum weight. It fits on my head quite comfortably and even though it’s 5 straps, I haven’t had any pain or imprint problems. The strap material gets a little hot on my head but I keep my room cool at night anyways so it’s but a foible.

Cushion is good too, it fits and sits on my nose fine without leaky problems. Just make sure to use the size gauge they provide on this order page, I used it and found that the cushion fit perfectly. NO fitPack option so make sure you choose your cushion size right the first time, otherwise you might have to exchange or buy a new one. Overall, this is a very good mask and I’ve been sleeping great the past few weeks.

Subject: Eson mask
This is my first time trying an Eson mask. I've never liked masks where I have to put a silicone "nose piece" into my nose, so I like the design of this nose piece. The nose piece goes around my nose instead of inside my nose, so this mask is much more comfortable for me in that sense. I also like how easily adjustable this mask is. The top part of the mask offers extra adjustment which made helped me get rid of the sags/leaks that I noticed the first night I tried this mask. The mask fits well and feels great. The only problem is that there is a forehead piece that makes it a little difficult to see after I put on my mask. I wish this piece was less obstructive to my vision, but I think the benefits of this mask outweighs that.

Probably close to the best nasal mask i have used so far, i am using it with Icon Auto and i have never had such low AHI reading in 4 years. With the combination of the Icon Auto and this mask i average 10 instead of the prescribed 14 on my old Icon Premo.
I have used my other masks as well with the icon auto and reading are also lower but i think this mask is definitely the most efficient one for me.

Craig G. You can disengage the main hose from the gray plastic end piece. The grey plastic end piece remains inside the hose but is designed to be separated from clear plastic swivel. This way you don't have to take the mask off when using the bathroom late a night. The best mask EVER!!!

I have been pleasantly surprised by this mask. It is quiet and comfortable and I have had no leaks despite a beard and sleeping on my side. Only slight problem is that it is a little hard to put back on in the dark while half asleep but I am sure a will get used to it.

This Fisher & Paykel mask resists moving around when sleeping. It also feels light enough to not overwhelm. It has adequate adjustment for perfect fitment. I have used this mask style for the better part of a decade and will for the foreseeable future.

Fabulous fit! Nice and quiet. Best mask of the almost dozen I've tried! The design keeps it from being in the way of seeing. The louver cover with filter means I'm not blow a strong stream of air on my wife. Most intuitive design I've yet tried.

I currently have an Eson headgear with the size listed as M/L.
I want to get the mask with headgear. Sizes listed are S or M or L.
So I'm not sure whether I should order M or L -- or is there a M/L option?
Thank you.
