I hear you re the S9, but I would recommend that you start the process moving to get a replacement, because there is shortage of machines generally out there, and it could take you months to get a new one. And, if the old S9 curls up it’s toes and dies in the meantime, you may be without a usable machine….
We have the RESMED Airsense 10 machines. With a pressure requirement of about 12, and using the FREEDOM batteries (without humidity or heat in the hoses) we get about 13 hours per FREEDOM battery. Also, we use the pigtail connectors. So, with four batteries altogether, we get about three to four nights coverage, each. And the batteries are quite small and easy to store or transport.
I have friends here in the US who registered in the recall for a replacement machine back in early July and are just now getting the replacement, supposedly tomorrow.
The problem may be the Philips recall in the US. Philips has been so slow in replacing the machines that many people are opting to buy a RESMED out of pocket and the machines are getting very scarce.
Hi, Sierra! What was the point if gettin them from Amazon? Better pricing? Faster availability? If they are too different, is it a good idea? They DO look less porous that the original….
Since the air pressures are controlled by an algorithm on a chip, and strives to be sensitive to even anticipating changes in your breathing patterns and hence pressure needs throughout the night, it might not take much to throw a monkey wrench into the process. It appears a little delicate…. Early in my use of PAP filters, I had one that seemed to develop a white growth on it. That alarmed me.
Have you spoken to your sleep doc or sleep lab about it? I’d start with that and see what they think…
I looked up the recommended replacement cycle on-line and I found a range: three to six months. A lot probably depends on whether the environment is humid, dusty or otherwise tough on filters. (I became a little overly conscious of filters, generally, after buying a house from my Mom and finding an air filter in a vent behind a bookcase that looked like concrete and had probably not been changed in many years. One visual experience can make an impression.)
Spot- It really doesn’t look that bad. I’m inclined to concur with your differential density thesis. Anyway, you have it working well again, and that’s what counts….
Spot: You might want to check on the recommended replacement schedule for the filters as well as all the other peripherals. Wrt the filters, I believe it is monthly re the RESMED machines. While it may differ somewhat wrt the Philips machine, I doubt that it is as long as six months.
I know it’s a nuisance (not to mention a cost) to keep up with the recommended replacement schedule. But given the concerns about foam degradation and off- gassing of plastics, it might be advisable to adhere to the recommended schedule. Also, I wouldn’t get creative about washing the filters, that could superimpose another cause of contamination. But I would be very concerned about a filter that was so dirty that it was blocking the air flow. You don’t want to be breathing air that’s gone through something that dirty. (Your lungs are a filter, too, and that’s the important one.)
