<p>OptiChamber Diamond's anti-static valved holding chamber suspends the aerosol longer, meaning you have more time to inhale your medication. The low resistance valves let you breath easily through the chamber with little resistance while the exhalation valve visually confirms when you breathe out, helping you track the success of your therapy.</p> <p>Lite touch face mask provides cushioned comfort: Soft-seal technology allows the face mask to rest gently on the face and requires minimal pressure to achieve a seal.</p> <p>Mouthpiece and adapter disassemble for easy cleaning and the OptiChamber Diamond has a flat bottom that lets it rest comfortably on a flat surface. Plus, the entire MDI spacer disassembles into 3 separate parts so you can more easily clean its interior. And to help keep the inner chamber clean when not in use, the OptiChamber Diamond features a tethered cap to prevent germs from entering.</p> <p>If you are just looking for the mask replacement, look <a href="https://justnebulizers.com/products/mask-for-optichamber-diamond?variant=42618944749724">here</a>.</p>
