The Philips Respironics Wisp mask is a minimal contact nasal mask made with a very soft and comfortable design. This mask leaves you with an open field of vision making it easier to watch tv or even read a book. The wisp mask has clips on its headgear making it easy to adjust. The packaging includes 3 different size cushions for your convenience, which makes fitting the mask a breeze. A great feature about this mask is that it is made with very few parts, making it much easier to clean.
