The silicone cushion for the Pilairo range of masks is made form a very soft latex free medical grade silicone. The pillows are designed with comfort in mind as the silicone is very thin which allows it to inflate when the pressure is applied to the mask. The inflation of the pillows is what enhances the seal on this mask as it seals at the entrance to the nostrils
The silicone cushion is the same for both the original Pilairo and the newer Pilairo Q.
There is only one size cushion for this mask
