Now using every night and have great AHI results

I have been using the Remzzz liners for 2 years. For most of the 2 years, I was using each liner multiple nights to save money. About 2 months ago, I started using a fresh liner every night. My AHI is now averaging 0.9 and i have had my first 2 nights of a 0.0 AHI after 3 years of CPAP use. Initial use of the liners reduced skin irritation and sores but using a fresh liner every night has eliminated skin problems at the point of contact. The amount of money that I could save in a year by using each liner multiple times turned out to be "too expensive".
