Review on Clear Replacement Accessory Suitable Home by Courtney Johnson

This type of mask is just what my 94 year old mother needs for oxygenation. The masks she received from a medical device company had large open holes on either side of the mask and a different connector to connect to the mask. These masks have small holes and a much more convenient connector. She says that with this mask she gets more oxygen. Little did I know there would be a noticeable difference in oxygen consumption with different masks and connectors. Wonderful purchase!
