RemStar Humidfied Replacement

It was great finding an exact replacement for my M-Series RemStar Humidifier Water Chamber. The replacement part is an exact match to the factory original. The website described the differences in the various chambers that were utilized for my humidifier making it snap to order the right one. CPAP Exchange has always been my "goto" online supplier for parts and accessories. As a company, they are quick, accurate and cost effective for me. Two Thumbs Up...Five Stars...well, you get the idea!

Will be buying again.

Products are the same as my insurance and I pay a fortune for at a reasonable cost.

Replacement Reservoir

The new reservoir fits perfectly. I really like the flip latch over the old slide latch. Now I don't have to press down on the lid to slide the latch. The seals line up perfectly and it no longer leaks. I should have gotten this replacement years ago.

Much improved over the old design

This new chamber has an improved design that fits better and is easy to clean. The new end clip is superior to the old sliding clip that was failing. I am very pleased.
By DreamChick,

It works.

Not much to really comment on a humidifier, it fits my machine just like the old design.

I haven't had to buy a new water chamber in a while. This design is an improvement over the older one. It doesn't have a rubber seal which will start to wear out and leak over time.
