Does This Exist? (humidifier idea...)
#1
Does anyone make a humidifier that uses UV light to sterilize the water?

If that existed, then the tank could be made to hold enough water for a week.

I've never seen one but that doesn't mean there's no such thing. While I can see the attraction of only filling the tank once a week, a few negatives come to mind....

1. You'd need a big tank, two litres or so, which wouldn't fit the form factor of any current machine

2. A lot of plastics break down under sustained UV exposure - this may shorten the life of the tank (or otherwise you'd need to use a more expensive material

3. It only takes a minute or less to fill the tank anyhow. Would the very slight improvement in efficiency be worth the extra cost and complexity of the UV system?

Sorry - just going into engineer mode and looking for fatal flaws before deciding to support an idea :grin:

We could have tanks with a float and needle valve (like in a carburetor) that fills from a larger container of distilled H2O by gravity feed.

As for sterilization, uV-c (short wavelength) light is used. I do not think it is transmitted through the plastic in tanks.

They use it in saltwater fish tanks. The units, usually in-line, cost anywhere from $75 - 200 and require constant water flow to work properly.

I admit I am lazy. I won't tell you the last time I really cleaned my CPAP stuff. But even I am not so lazy that I won't dump and refill my humidifier tank.

And I admit I like to tinker. And I like my fish tanks. But setting up a UV system just for my CPAP humidifier that uses less than 2 cups of water a night? Now we're back to the lazy part.

UV water treatment is frequently used on wells to ensure no pathogens are delivered. I can't imagine using it for a humidifier, but then I don't understand a $10,000 watch either.

I have a $60 room humidifier that has a uv sterilizer in it, so clearly it doesn't cost much.

I would like to go to bed, and not have to mess around with water every single day. So if I could have a large tank, it would be great. The unit sits on a small end table by my bed. The added size would not matter. If I travel, I could swap in the regular tank. I have a Resmed A10, and the tank could be as big as needed without altering the machine in any way.

There does exist an addon humidifier for CPAPs that has a bigger tank. The F&P HC150. Because of its larger tank, you could maybe get away with having to fill it up every night and just wait for it to get low enough. Because it is clear, you can see into it and can tell when it starts to get skanky.

A few people have added an additional 2nd humidifier tank with the F&P HC150. I sure would love to increase the actual humidity. I can't remember where the F&P connects (last part or before humidifier).

I have a Philips BiPAP System One 760. Isn't there a humidity sensor on the hose that would adjust down the humidity level if it "sees" more coming in?
Sleep Apnea has given me a terrible memory. Please forgive me if I've repeated myself.

I have something like that except for the distilled water. It's called a toilet.
