I have used CPAP for 12 years (1 Philips, 2 Resmed Airsense 10). Each one was provided under different health insurance, United Healthcare, Blu Cross Blue Shield and Cigna. I prefer paying a single lump sum for my co-pay, but some insist on 10 monthly payments if the supplier can verify you are using the unit. But wait, there's more. Each insurer had a different schedule for how often you should change the tubing, mask, hose and filters. I have boxes of spare parts because I would not replace per the insurer's schedule. I always replaced the air filters, always used distilled water and cleaned, but never placed a tank. The mask and hose are sturdy, so I clean and reuse until they leak too much.
