I like the product, however it is made of plastic and the original one cracked. I ordered a replacement on August 13, 2022. Now this one has a crack, and I am careful in my handling of the water chamber as I do not want to keep buying them. So thanks to the Memorial Day sale I went ahead and reordered another one (my 3rd one now, within 2 years). I will take extra care and hope it does not crack again. That would mean there is a design flaw, which I will send my disappointment to the manufacturer.

I've used a machine similar to the S-11, before. The hinge points on the water tank kept breaking. Took it back to medical provider. Finally received the S-11. Same tank arrangement. Hinge point broke after 6 weeks. Glad to find a replacement tank at CPAP.com :-) I don't have to fight with the medical company who issued the machine. Now I'm on the 'Auto-Replacement' schedule :-) Have been using a CPAP machine since June of 2004.

Does the job, awkward design

This does what it's supposed to, but the way it's made means I end up with water spilling out of it almost every time I fill it. I don't know if it's slanted or what. Just be careful and maybe tilt it a little toward the non-hinged end when filling it up.

I use the papitizer UV
26 June 2023

I use the papitizer UV sanitizer and it tends to cause these to start to develop small hairline cracks after about 6 months. So I have to replace a bit more often than usual. But it's a fair trade off for the ease and not having to soak as often. Will try a dishwasher safe version next to see if it holds up better.

Perfect Res-Med Water Chamber replacement

Perfect Res-Med Water Chamber replacement. It was delivered well packaged and on-time at a fair price. Works perfectly with my machine. Great company

QUICK SERVICE DELIVERY OF A GOOD PRODUCT.
1 August 2023

Great quick replacement. The humidifier tank that came with my ResMed air sense 11 was causing air leaks. I ordered this one to replace it while waiting for my insurance company to send me a replacement of the original. It came within three days of my order and solve my problem

Replacement = New
30 September 2022

The replacement was the same as new; not a shoddy substitute.For some reason there was a delay in shipping, so I contacted the company.I was helped by Shelby, who made things right: and she made things right, quick.I had my replacement the next day.Thanks Shelby!The reason I purchased this water chamber is because the one I have runs out of water at about 2 a.m. and I am awakened by dry mouth.I simply replace the dry chamber at that time, with this one, which is full of water, and I am back to sleep.Also the price from this company is good; I found other companies that asked twice as much money as this company does.I get the feeling that they want my business.

Replacement for original chamber came with Airsense 11
21 February 2023

This camber seem to stay cleaner with everyday rinse and dry. And with weekly cleaning it seems clean and plastic seems to stay clear and nicer looking. Very satisficed with this purchase and will resupply again when needed.

The water chamber fits and
24 April 2023

The water chamber fits and works well. The only thing I didn’t care for was having to swap over the white release button on top of the chamber. The new tank didn’t come with one, so I’m glad I had my old tank still. It took a few minutes to see how it detached from old chamber, but with a couple flat blade screwdrivers, I was able to remove it successfully without any breakage for use on the new chamber.

Why didn't I get it earlier?
5 May 2023

I got the humidifer 4 months after the machine. I was experiencing dry mouth and my lips very so so chapped every morning. My friend who is on CPAP advised me to get the humidifer. I can say that my complains are almost fully gone. The humidifier itself is a bit hard to fill but it is manageble.
