I got an Airfit N30i small starter pack SKU 63801 with a small head frame and three nasal plugs (S, SW, M) that cover the nostrils and an AirFit N30i standard starter package SKU 63800 with three nasal plugs (S, SW, M) that cover the nostrils for a ResMed Air Sense 10 machine that I can't use. I tried the small frame and medium mask once.
I prefer to give it to someone who has to pay a co-pay.
If you are looking for CPAP supplies, St Vincent DePaul in Kenmore has some nasal in-the-nostril pillows for ResMed and some Philips supplies.
If you need a new Airsense 10 machine, the MSHH Donor Closet in Edmonds has three of them, four hoses, a standard tub, some full face pillows, and a Phillips Nebulizer.
