It is interesting to see how CPAP is used and covered by insurance in different countries. In my country, South Korea, CPAP is available for rent if you have certain medical conditions, and the rental price is fixed. I pay 15 USD (20K KRW), and the Korea NHS pays 60 USD (80K KRW) per month. I've been using Löwenstein's CPAP, and it works great without any problems.
