Reviewers Tip:

When I am experiencing harsh environments such as dry air, I like to turn my humidifier on 20 minutes before bed so that it has time to warm up and is ready to go when I am ready to sleep. You don't have to do this every time, but it's a nice added bonus when I find that the environment I am sleeping in is harsher than normal

No Prescription is Required.


Can I use normal tap water in my Respironics water chamber?

While you can use tap water, we recommend using distilled water for all water chambers in order to provide the best results with your CPAP device. Distilled water will also extend the life of the Respironics water chamber.

How often should I be cleaning my water chamber and with what materials?

We recommend cleaning your Respironics water chamber daily. Warm water and a mild detergent usually do the trick.

Is a humidifier really necessary for my CPAP device?

Your CPAP machine will work without humidification and therefore you do not need a humidifier and water chamber, however, many CPAP users find that they are congested in the morning or experience discomfort after using their CPAP machine. Humidification will add moisture to your tube and help relieve any potential discomforts from congestion.

In the package you'll find two lids, the clear one is for the System One line of CPAP machines, and the dark, charcoal lid is used for the 60 Series machines like the one I have, a DS560TS (with heated tubing).

This water chamber works with both System One and 60 series humidifier with plastic or heated tube.
The nice thing about his water chamber is that you can take it apart and set it in the dishwasher to clean it. Filling the chamber with water is easy as pie.

I shopped around and finally found Respshop to have the lowest price and I stopped here to shop for my cpap supplies. Respshop and CPAP has a nice ring together.

I have found that this chamber has a short life, no more than three months, because the plastic plugs which hold the metal disk on the bottom of the humidifier come loose causing a major leak.

Is this a product defect or is the three month period the normal life expectancy?

This has happened numerous times and up until now I have come to accept it and keep an inventory of my own so as not to go a night without my CPAP.

Received this in the mail sooner than expected. Filled the water chamber to the max (1-1/3 cups of water), and put it to work right away. Should have ordered my supplies from you guys a long time ago. Your price is much cheaper than other online stores. I'll order from Respshop from now on.

Exactly what I needed for my machine. I always like to have two to put in one while I clean the other. The bottom plate for the last one I had for a long time (that was not from this company) popped out. It was a good price and the shipping was fast.

Perfect extra. I bought it with the machine, although it is included. But you should change it after some time (I will do it after 2 years probably). Nothing more to say!
