CPAP FILTER, CHANGE OR NOT TO CHANGE
#11
I change my filter every 6 months or so, I don’t have a super dusty environment.

pavelow360, it totally depends on the conditions where you run your machine and that can even change by time of year. If your filter is turning slightly grey, then it is time to change it. Don't wait until it is really dark.

In the winter, since I don't open the windows, I can go almost 2 months without changing my filters. I have cats, so I get cat fur and other buildup on the one side of the filter. In the summer, I go 2-3 weeks before changing the filter because of the dust brought up by road construction and pollen from open windows.

Filters are cheap; your machine is not. Medicare allows 2 a month because some people live in dusty areas that require two a month. You are not obligated to that schedule (many insurance companies follow the Medicare schedule). To give a good example, my sister lived in Santa Monica for a couple of years during graduate school. Within a couple of weeks without careful cleaning, EVERYTHING was grimy. Yet, only a few miles away in Culver City, you could go months without dusting.

Just because a 'colleague' chooses to do something doesn't make you a lemming that you must also do the same thing. Think about why the manufacturer has such a recommendation. A lot of people do stupid things but because something bad hasn't happened to them, they think it's ok. Ask the ER docs and they will tell you an entirely different story.

I see no need to change the filter on my ResMed before it starts to look gray. Filters actually become more efficient at removing particulates as they get loaded. The main concern is compromising air flow which may damage the machine.

I washed the foam filter on my old respironics machine every few weeks and seldom changed the white filter.

For those with good insurance, it's probably not an issue. I think my copay is $0.45 per filter. So I sometimes change it more frequently since it requires no more effort than checking it. It depends on whether I have spares on hand.

Every month seems excessive. Every 3 months I get a new mask, hose and filter from my sleep clinic.  They should give you one whenever you replace the mask.  You probably won't notice much of a difference cleaning it monthly unless you have allergies.

Okay, so maybe it's the humidifier. It has had some white coarse stuff in it, ever since I ran it dry. I've tried to wash it out, but it's going to need some major elbow grease. Maybe that's contributing to a smell.

I didn't smell anything last night. So... who knows? I'll try to pay attention to factors.

No flatulent pets - I kick them to the kids' rooms when they get that way!

White crusty stuff in the humidifier is probably calcium from the evaporated water. It will usually dissolve in vinegar. Let it soak, scrub, then rinse well.

Hydrangea, do you use distilled water in your tank?
Distilled water will keep it maintennce free, once you get it cleaned.

Washing and rinsing with vinegar is a good choice, but if you can't get it clean, consider a replacement chamber.

I use very well-purified water, but no not distilled. 

I had zero build-up until it ran out of water one night. :-/

Okay... I'll buy some vinegar.  

I'd love a replacement chamber!  Do I just ask my DME for one?  Must I wait a certain amount of months?  Is it all dependent on insurance?  (Thus, I need to call my insurance to ask what they will approve.)

Humidifier chamber replacement interval is usually 6 months. They are not a very expensive item to buy.

I pay $0.87/gal for distilled water at the grocery store. It leaves no sediment. I'm not sure what you mean by well-purified water but deionized, Reverse osmosis filtered water, or distilled water should not leave a sediment.
