Better Masks

We need better masks (consumer respirators) for protection from Coronavirus as discussed by Patient Knowhow and our partners in Harvard Business Review. This includes superior filtration and fit, comfort, reusability, and style. At Patient Knowhow we have been on the lookout for better masks with these properties. Below are off-the-shelf options you can purchase online as well as a number of new mask designs that push the envelope in these dimensions. Places such as Nelson Labs do testing, and NIOSH has a certification process. Watch the video below by Minute Physics and read these recent papers (1, 2, 3) to learn why it matters. Which is best? We are not making any recommedations because it seems the right mask for each person is different based on their preferences, but the at minimum they need to promise N95 level filtration and have features to form a seal (fit) with the face. Good news is that several off-the-shelf options are available. Although not yet available, the section on masks to watch are innovative approaches worth taking a closer look at. If you know of any that should be included here please reach out to me at sri at patientknowhow dot com or @sri_srikrishna on Twitter.
