Dear Mr. Garrett Larson and Mr. Rory Larson,
I am so pleased that you have reached out to me last Friday (Mar 20th) and brought me examples. I have personally examined the material, especially the area of 3 valves with HEPA filters, and areas of multimedia joints/seals.
My immediate assessment is good and useful in non-patient contact type of healthcare setting as voice penetration is significantly reduced wearing this. Currently, there is none to minimal masks for laboratorians who process and test large number of patient specimens for coronavirus. The 3D masks will be really useful in this setting without concern for verbal communication.
We really like the reusable feature of this material and the air valves that were designed for changing out HEPA filters after disinfection. Please send us 8-9 additional 3D masks for a mini-trial and I will distribute them to our technologists who perform coronavirus testing daily. We will collect data on fitting, contact security when fasten on face, breathability, comfort on prolonged wearing (1 hour, 1.5 hours, 2 hours, etc), such as condensation, odor, interference with eye protective goggles or glasses. Please remember to send recipes for disinfection soaking solutions. Once we have everything, we will start a trial ASAP with good scientific recording and documentation.
We really appreciate you and look forward to working with you!
