Eson 2 Nasal Mask by Fisher & Paykel
The Fisher & Paykel Eson 2 Nasal CPAP Mask is designed to meet the needs of CPAP users and sleep therapy professionals through every step of CPAP therapy. The Eson 2 is built for performance and comfort with a focus on ease of use.
With only three simple parts, this nasal CPAP mask is easy to clean and assemble. The Eson 2 is quiet and minimizes draft, allowing for a night of uninterrupted sleep.
Eson 2 Mask Sizes
The Eson 2 comes in sizes S (Small cushion & Small headgear), M (Medium cushion & M/L headgear), and L (Large cushion & M/L headgear).
It also comes in "FitPack" packaging which includes cushions in all three sizes – Small, Medium, and Large – as well as a M/L headgear.
Fitting the Eson 2
- Stretch over – for a quick fit, the mask stretches directly over your head.
- Hold the bottom gray straps with the mask facing downwards.
- Guide the headgear over your head so that the silicone seal is resting on your forehead.
- Place your hands on the bottom straps on either side of the mask.
- Pull the bottom straps out and downwards.
- Ensure that the silicone seal rests over your nose and that the blue top strap is sitting on your forehead.
- Adjust the fit of the headgear by tightening or loosening the velcro tabs. Start with the two velcro tabs on the blue top strap, followed by the two bottom straps.
Fitting Tips
- If you experience mask leaks, lift the silicone seal off your face and reposition it.
- Ensure that the headgear straps are not fastened too tightly.
- The forehead strap should rest horizontally on the forehead, just above the ears. You can adjust the strap on the crown of your head to move the headgear further up or down your head.
- A good fit is snug around the head and not too tight.
Cleaning
- Unhook headgear clips from the mask frame.
- Remove the silicone seal, diffuser, and swivel from the mask frame.
- Wash the silicone seal, swivel, and frame in warm soapy water after every use.
- After washing, rinse all parts thoroughly under running water.
- DO NOT CLEAN ANY PARTS in your DISHWASHER.
- Once a week, wash your headgear and diffuser in warm soapy water.
- Do not soak any parts for more than 10 minutes.
- Air dry all parts out of direct sunlight.
Assembling Your Mask
- Push the silicone seal onto the mask frame, using the blue ring for orientation.
- Push the swivel onto the end of the elbow and place the diffuser onto the elbow.
- Thread the forehead straps of the headgear through the slots of the mask frame.
- Thread the headgear clips onto the headgear.
- Hook the headgear clips back onto the mask frame.

Eson 2: Quiet. Comfortable. Great seal.
Quiet. If you are looking for a quiet mask, the Eson 2 is the answer! The reusable diffuser (the part covering the expiration valve) ensures the noise-sensitive sleeper a great night’s sleep. Although a tough tug to get off, you can wash the diffuser periodically in mild soap and water.
Comfortable. The Eson 2’s blue headgear is soft and light, making it very comfortable to wear. The special velcro on the straps is designed to be durable. You can easily remove the mask by down-twisting the clips or by pulling open the velcro straps. It is designed so the straps do not pull out all the way. Simple.
Great seal. The design of the Eson 2 makes it a great-fitting mask. The ball-and-socket design on the elbow allows more flexibility with the tubing, reducing any tugging that may cause leaks.
My customers love this mask for good reason!

Subject: Thoughts after switching from Eson to Eson2
My Eson 2 mask arrived a few weeks ago after I decided to upgrade from the Eson 1 that I had been using for a few years prior. The biggest upgrade is the sheer comfort I get from the Eson2. It's astounding. I can't believe I was putting up with the Eson 1 after I made the switch. It's just so different. My face also feels free in the morning and-- lo and behold-- I don't have to deal with marks on the sides of my face or on my forehead in the morning anymore either. I'm very, very happy about this to say the least. The Eson 2 is also easier to clean for me personally. And the mask works just as well as the Eson 1. I haven't had any troubles with leaks or the like.
The Eson 2 is definitely an upgrade to the Eson 1 and I recommend upgrading just for the comfort if you have the funds to do so. The comfort makes such a difference and I get better quality sleep from the eson 2 but both the Eson 1 and 2 are very good masks and I would recommend both of them to anyone.
I am very pleased with my new mask. Previously, I used the original Eson nasal mask. My doctor suggested that I try this updated version with my new Philips Respironics Dream Station cpap machine. This one seals well with my mustache. The new design of the clear plastic piece that runs from the forehead and down the bridge of my nose is angled a little different than the original Eson. This seems to put better pressure onto the nasal cushion and creates a better, and more quiet seal. My wife noticed a big difference. In fact, it was so quiet the first night that she says she checked on the machine while I was sleeping to be sure it was powered on! THANK YOU !
Subject: Returns.
I received a Fisher & Paykel mask over a week ago that doesn't fit and asked about returning it with no reply.
Until this issue is resolved.
I will not be purchasing anything from Respshop again.
Hi there, how did you try contacting us? That is very unusual for you not to receive a response. Please give us a call at 866-936-3754 and we can definitely give you a hand. I apologize for the inconvenience.
Top plastic on forehead is very delicate plastic. Mask works good if it wasn't for the weak design, need to go back to Original Eson, its made with thicker plastic around forehead area. I have had to replace 2 mask already due to same problem.
I am sorry to hear that. Please remember if your mask does not work for any reason you can contact us within 30 days for an exchange!

The machine itself is good. But I absolutely hate the place where you connect the hose to the mask, it is to short and comes off way to easy. It needs to be built better. But hey it's a cpap machine that you don't need a prescription for.
It sounds like you may have a defective mask. Please call us so we can get this taken care of for you!

this is the fifth time I have had to replace this piece. Its always the same plastic pieces that break, no matter how careful
i am. It is the piece of plastic at the top of the nose piece that touches the forhead. they need to be closed to strengthen them.
The Fisher & Paykel Eson 2 is a great mask, fits well, the defuser is quiet., this is the third one I have purchased, highly recommend it
This is my third Fisher & Paykel Eson 2 Nasal CPAP Mask, it is really comfortable to wear, easy to fit and adjust.
Subject: Good seal
The mask has a good fit/seal. It is little inconvenient if you move around in your bed.
May I know if that means it contains all S/M/L sizes in the pack?
1) do you have problems shipping to Canada?
2)what customs declaration do I need ?
Thanks.
It does not however come with a diffuser, the Eson 1/2 and the P30i are some of the only few masks that have the diffuser option.
