What CPAP did you say you use? How do you turn the humidifier off?
With my old F&P, the airplane mode turned off the humidifier, with the AirSense 10 the water basin still gets warm, and the heat indicator lights on the display in Airplane mode.

Any of the searching I have done on this shows that it has been a long-standing problem. The sensor probably wears out.

The old topics on this same problem https://myapnea.org/forum/cpap-machine-won-t-shut-off-part-deux

I am wondering if it is because of a software update.

I use Fisher & Paykel masks, they come with a cloth or cotton defuser. I disliked the Resmed masks because of the open vents,

Jeremy, My CPAP machine, AirSense 10, has a small air filter built in. It isn't HEPA but it helps reduce some garbage before it gets to the machine. I did notice that the filter on my last machine wasn't as dirty after I started using the Honeywell air filter. The reason why the prices have increased is supply and demand, with COVID more air filters are selling, prices go up. It is winter in the Northern Hemisphere as well, and when people are stuck in doors people worry more about air quality.

tallullahjo (I don't know if you have returned to the forums) An article about different air purifiers. I don't trust most "best of" articles on any item, there are many and each article produces different results. If there was any science behind the article there would be one or two devices across all articles that stand above the others. However, knowledge is power, getting as much information as possible is helpful. https://www.thegoodtrade.com/features/best-home-air-purifier

You can always make your own. (This is my friend from the above comment) He has several air filters.

I made one of these filters as well.

I use the Honeywell brand, they have different sizes depending on the room. I have two, purchased at the same time and I am happy with them. The Honeywell has a carbon prefilter that gets the larger dust particles and removes the bad smells out of the air. The second filter is a HEPA filter and gets the fine particles that are the real problem.

The carbon filter needs to be replaced quarterly, the HEPA filter yearly. The machine has an indicator on it letting you know when to replace the filters. I usually vacuum the prefilter a few times before replacing it. The replacement HEPA filters are expensive. All true HEPA filters are expensive. There is a combo package that sells the carbon filters and the HEPA filter together. With this you need to cut the prefilters to size. This isn't difficult but I would rather have pre-cut filters.

A friend of mine purchased a VERY expensive air purifier, but he has some lung issues, he wanted top of the line. I will ask him the name and get back to you.

EDIT: If you watch the video below he shows the expensive air purifier he purchased, a less expensive unit along with the air purifier he made.

The air purifier will clean the air in the room, it has nothing to do with apnea. Two issues. The air purifier will not fix sleep apnea or replace your mask.

Try Terro ant killer. (orange box, white letters on a blue background. ) Hopefully the ants will be more attracted to the Terro than you. I can't believe you have ants in the winter, it is dry the ants are probably looking for water, A nice humidifier on a warm CPAP machine would attract them.

It is intermittent, it was shutting off after I replaced the hose, now it isn't shutting off again.
