"Got it as a back-up. I've always been afraid my original would crack, or the outlet tube would break off, or that the thin aluminum base would wear through from sliding out out and into the slot on the machine. Now I'm set with a back-up."

"The item works fine but is extremely difficult to clean--I wish they would come up with a design where you could remove the top and actually scrub inside."
"Reasonably priced; fits well. It is difficult to clean; I use a bottle brush to do a decent job of cleaning the interior with a mild dish cleaning product about once a week. Like most all cheaper CPAP units it uses a very thin aluminum plate for the heat exchanger. Remember to use a good distilled water AND drain daily turn upside down to keep water off the plate. [the CO2 in air shifts the pH to a slightly acidic liquid about 5.5 and if left in the unit will react with the aluminum and you'll see little white specks or worse black spots. These will eventually penetrate the plate.If the unit leaks; you could be in for new CPAP. I change my Water Chamber every 6 months."

"Water Chamber was original manufacturer's equipment. Exact fit and function returned my CPAP to original function."
To care for your humidifier simply empty and clean the water tank each morning. Only distilled water should be used in the humidifier to avoid mineral deposit build up.
Why do I need to use distilled water with in my humidifier chamber?
Use distilled water to help keep the humidifier chamber clean and mineral deposit free. Tap water should not be used as it will leave hard white mineral deposits in the chamber as the water evaporates, or it may lead to mold growth. Cases of lung disease have been connected to using contaminated well water in a CPAP humidifier.* Source
If distilled water is not available where you live, use bottled water. It will be important to clean the chamber each morning, do not leave standing water the chamber between uses.
