Quick and Easy respirator maskFollow project
It seems obvious that wearing some kind of mask is better than nothing, for the user and others. The problem is of course that there aren't enough of the 'proper' ones to go around and the government is concerned about recommending them for fear of increasing the demand for PPE that the NHS so badly need. It would take a long time to ramp up production of the certified N95 masks. That's where my idea came in. There is a fairly detailed explanation of it's key points in this link so I won't repeat that here.
1 Uses household tissues as the filter.
2 Large filter area. This reduces the flow rate per area and allows more layers (12 – 16) to be used, thus increasing filtration efficiency.
3 Comfortable because the only thing against your skin is the tissue.
4 Shaped to fit snugly around the nose to make a good seal
5 Everything you need is printed, apart from the filter itself. No need for rubber bands, elastic or shoelaces!
6 Adjustable side straps.
7 Only 15 grams of material (PLA) and 1 hour 8 mins to print.
