The all-in-one Sil-Flex Silicone Mask offers a soft cushion for better comfort. Its ergonomic shape includes lower dead space and improved air circulation. Whenever a mask needs to be sterilized, an autoclave with a temperature of up to 134 degrees C does the job well. There are convenient plastic ribs (22F) available for dethatching and attaching the headgear. To reduce skin irritation, the masks are bio-compatible and feature latex-free material.
