Sleep Apnea Support Group
Sleep apnea is a common sleep disorder characterized by brief interruptions of breathing during sleep. People with sleep apnea partially awaken as they struggle to breathe, but in the morning they may not be aware of sleep disturbances.

I bought some Remzzzs mask liners a 6 pack and although they say to only use them once you can wash them and get about 5-6 uses. I then made a template of what I needed from their liners and went to a fabric shop and got 3 ft of 50% cotton / 50% poly fabric and cut out my own and they also last 5-6 uses, the next time I bought 3 ft of 50% cotton / 50% lycra fabric. That last me about 3 months and costs about ten dollars. No need to do any sewing.
Also the CPAP you are talking about is an Auto, they are now probably the most used CPAP's but are also the most expensive, I have a Resmed Autoset and can set my pressures so I have a low and high pressure. In my case my low is 5 and high is 15, mine adjusts as apnea's are detected to the pressure I require then lower to the low pressure when not required. This is more for comfort sake.
