    This is the quietest mask. Adjusted correctly, l don’t dislodge the mask and my nose doesn’t get irritated. My wife can sleep next to me in peace. I like to change the diffuser weekly as you exhale through it.

    Love this mask. It doesn't make noise nor hurt anywhere. Can't ask for better than that. My last one lasted more than 9 months. I bought a second one recently and am really happy I found something that didn't hurt my face or slip off during the night.

  • Filters for mask

    If you ever forget, when you do change it, you will see how dirty the air we breathe is. It is a must to change out the filter and it is very easy to do. These are a must to have!
