  • Just what I needed

    The manufacturer of my CPAP machine stopped making the water chamber so I had to shop around for it. Found it at Direct Home Medical at a very reasonable price.

  • Dry again

    I like the new design on this tank. The older tank would leak around the heat plate after awhile. (Ruined top of night stand) This design looks like it will last longer.

  • Never Disapointed

    I ordered a spare water chamber for my M-Series Remstar BiPap Humidifier, just in case. I have had a few close calls , when filling the water chamber,when almost dropping it. My original water chamber is still like new at almost 4 yrs. old. I attribute it's longevity, to using only Distilled Water, not tap water. Distilled Water does not promote calcium build up & spotting, keeping it clean and spot free. The Water Chamber is the same one as the original.

  • Humidifier chamber

    I really like the chamber I received. It is much different than the one that came with the machine but it's well built and fits perfectly. The chamber came so quickly! Great service.

  • excellent upgrade

    I replaced the humidifier tank on my cpap with the new design. This tank lends itself to much easier cleaning. There is no fighting with a separate seal as you try to put it back together. The new snap mechanism makes the cleaning experience much less tiresome. Great product and great service.

  • The web site hlep select the right item the first time

    I ws wondering if I could even get a replacement water tank for the CPAP and if it would fit. Your web site not only had the right tank but picture of the selection so I could look at my tank and match it to the picture. I got the new one in just a few days, I was able to track it to my home and it fit perfectly. Now I'm a fan. Uncle George

  • Extremely pleased

    The water chamber is exactly what I needed to replace my other one. Replacement was needed b/c one of the plastic connectors was misplaced by the person who filled the chamber for me. (Don't ask. I never take the connectors off. I have been bedridden b/c of surgery for past 3 wks.) Is there a way I can order the connectors separately if those pieces come up missing again. I could not find them on your website. Overall I am extremely pleased w/the easiness of placing an order, the response time to get it (and other orders) in the mail, and the speed (4 days) it takes for the order to reach me.
