My f30i mask came with a Wide sized pillow but leaks were often a problem, The M size was a much better fit and after several cycles of adjustment the leaks totally stopped. I really appreciated the fast delivery as it arrived in two days!
They are reasonably effective. The container does a good job of keeping them moist (unlike other types of containers). I like that they are unscented.
Best machine I have ever had. I have had a machine from the doctor and was not as good as this one. Will definitely be ordering from this website again if I need any new parts, accessories, or machine. Runs so much quieter at night and helps me breath better. So grateful for this wonderful machine to help me get the rest I need to continue my daily routine without being so exhausted. Thank you kindly!!
