Mask Fitting

  • Stretch over - for quick fit, mask stretches directly over your head

  • Guide the headgear over your head so that the silicone seal is resting on your forehead
  • Place your hands on the straps either side of the mask
  • Pull out and downwards
  • Ensure the silicone seal rests over your nose, and the blue top strap is sitting on your forehead
  • Gently take the headgear strap of the mask headgear.  Starting with the blue top strap followed by the bottom straps.  

Fitting Tips

  • If you experience seal leaks lift the silicone seal off your face and reposition it again
  • Ensure the headgear straps are not fastened too tightly
  • The forehead strap should rest horizontally on the forehead, just above the ears
  • A good fit is snug around the head and not too tight


  • Remove your mask by placing your hands on either side of the mask frame and pulling the silicone seal off your nose, and lifting the mask back over your head.
  • Unhook headgear clips from mask frame
  • Remove silicone seal, diffuser and the swivel from mask frame
  • Wash these parts in warm soapy water after every use
  • After washing, rinse all parts with fresh water
  • Once a week you should also wash your headgear and diffuser in warm soapy water
  • Do not soak all parts more than 10 minutes
  • Air dry all parts out of direct sunlight

Assemble your mask

Quiet. Comfortable. Great seal.
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 was designed to be durable. You can easily remove the mask by down twisting the clips, or, by opening 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 flexibility with the tubing, reducing any tugging that may cause leaks. The super soft cushion’s roll fit design prevents over tightening, keeping a good seal. This mask can manage high pressures without any increase in leaks. Sold as a fit pack, with all three size cushions, takes any size insecurities away.
My customers love this mask for good reason!

Please Note:  The Eson mask cushions are not compatible with the Eson 2 mask frame.

Subject: Good seal
The mask has a good fit/seal. It is little inconvenient if you move around in your bed.

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.

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.

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!

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 !

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!

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.

Hi. I am Canadian. I have a prescription and I need a bipap machine. We don’t know the settings yet

Thanks. (Asked on 03/05/2021)

Yes it is complete and we can ship it to New Zealand.
I’ve used the Eason 2 for several years. Size ML. Ref 400HC568. I’d like to try another to see if it’s more comfortable and durable. The diffuser breaks too easily in Eason 2. What is the top rated or most popular that you might recommend? And what size is similar to my ML? (Asked on 07/10/2021)
The N20 would be a comparable model. You can view it here: https://www.respshop.com/cpap-masks/nasal/resmed-airfit-n20-nasal-cpap-mask-with-cushions-p-1440.html

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.
