Well, 4 cats certainly comes under that "or as needed" part of filter replacement




The problem that I rant against is that the greedy DMEs have seized on the max replacement frequency, and said "well, if we tell people to throw away perfectly good things as often as we can bill insurance, WE'LL MAKE MORE MONEY!!!!Gryphon wrote: ↑Tue Feb 19, 2019 2:57 pmI keep thinking about the replacement schedules that used to circulate now and then. IE: New mask cushion each month for FF, one filter each month, one hose every 3 months etc... Didn't mean to say it like it was doctrine. I'll make sure to remember the "max replacement frequency" term for future if I talking about what insurance will replace and how often. I don't think of the replacement schedule to mean that - you have to throw away the other parts... because you can clean or wash them...
Sure, they'll sell you two p10 mask pillows a month... happily... but I can get well over a year outta mine.
I just got a box full of those AB filters off ebay, https://www.ebay.com/itm/Nispira-in-lin ... 2749.l2649 maybe not the best price, but cheap enough... These are the first ones I've gotten that were in *sterile* packaging, not just in a baggie. I think they might have gone a bit overboardGryphon wrote: ↑Tue Feb 19, 2019 2:57 pmFor me - because of my allergies - I tend to go with what ever is the quickest for replacement when it comes to filters... For everything else I'm like trying to pull off a never ending marathon - just waiting to see how long I can use my mask and hose before it breaks. I'm on year 2 for my hose and still using the same mask for over a year now, because I changed my mask type to a new style.

Same for me with the masks, I've had three masks in 9 years. The frame finally broke on my Mirage Quattro and I had to buy another, then I switched to the P10... and have been on the same one since... I may be switching to #4 with the Bleep, though.
I've had 2 hoses, my current one is probably 4 or 5 years old, it's snaked around behind the headboard and only a little of it comes over and drapes down... it's a 10 footer.
