corona mask with 3m+moldex+alternate and visirholder and exhale
Description
For use with TPU. This is an Advantage of my Corona mask for zigarette filter tubes. It provides 2 hoses, one for Moldex-Filters, one for 3M-Filters. A Lid is included to close not used hose. If you cant get a Modex or a 3M Filter you can close one hose (if breathing with nose the upper if breathing with mouth the lower hose for maximal long filterway) and fill the mask with wadding eg there are Extractor hood filter with activated carbon for kitchen or something else. Inside the mask is a space for this with a little "door" wich has a big knob as hinge and a little knob against unwanted opening of this "door". Furthermore it has a exhale vent for the hole next to nose, simply push it in there, it has a simple pressure relief valve like better comercial facemasks have for easyer breathout wich prevent mask to loosen from skin due to overpressure while exhaling. If you dont want/need this there is an alternative closing knob included wich is printed directly under the valve (yes this are two parts not one even if your support may let them look like one pice) . The hole can be used for oxigen tube as well if you modify it ( Tape sealing or silicone sealing ). Furthermore there are two nose bridges wich you may use if you make yourself a face shield , the mask has a suport for that bridges. LAST NOT LEAST THIS IS A CONCEPT ! Use in emergency (if no comercial masks are avaible) AT YOUR OWN RISK. NO MEDICAL PRODUCT. Moldex and 3M are Trademarks of their owners and the hoses may fit for the Filters they produce but are not tested for that either by 3M nor Moldex nor myself, it might only fit by providing the needed size of the filterhooks in the hoses but may not provide the needed sealness of the original hoses at the original masks. If you have either 3M or Moldex Filters use the propper Mask mentioned and sold by 3M or Moldex for your own secureness if you can get them. This Item only provide basic improvement of your defense of Corona depending on the Filters or Filtermaterial used and the sealness to your skin, and the quality of your printout not to have holes/cracks. It may only provide this by protect against drip infections and preventing you to touch your face while wearing it. Any liability resulting from the use of the item is excluded.
