The Quattro Air is simply designed with only 4 part assembly that eases using the mask even by a first-time user. The mask consists of Soft Edge Headgear, Quick Release Elbow, full face Spring Air Dual Wall Cushion, and plastic lightweight frame. It takes hardly any effort to assemble and dissemble or clean the mask with such a simplistic design. It weighs just over 3 ounces, which is almost 45% less than the ResMed Mirage Quattro. Moreover, there is practically no adjustment needed with the Flexi-Wing forehead support that has minimal contact with the forehead and eliminates the pressure. The Quick-release elbow allows users to just pinch each side for hassle-free attachment and removal. You can swiftly attach and detach the tubing from the elbow using the Quick Release straps.
