<p>JamesBowden: </p> <hr /> <div>I want to make a positive pressure hood for use when we return to the new normal. it would be composed of:<br /> a full face mask with a seal all around the face,<br /> a hepa filter for incoming air,<br /> a blower capable of passing air through the heap filter and creating a positive pressure in the hood/fce mask of approx. 1 inch of water column, to prevent entry of outside (possible virus ladened) air.<br /> it must be powered by a battery.<br /> <br /> this is NOT for use by medical workers<br /> <br /> I am a retired engineer living in a nursing home. I have symptoms of COVID so I made not have a lot of time to play with this design. a quick response would be appreciated.</div>
