This is maybe unrelated, but is there a diy version of a mask for filtering air? What I want is a full face mask with filtered air for working on cars, around solvents and paints, and such, but the masks usually require the force of your own lungs to pull the air through the filter and through a 1 way valve when you exhale. I want something battery powered that does the air filtering. What am I looking for and how much does this cost? And would something like this be usable for what I had envisioned when I read “pandemic ventilator” which would be like something you could wear while you were out and about and it would filter everything you’re breathing.
- viklove 7y agoWhat would the battery be for?
- lukevp 7y agoTo power some type of air pressurization system so that it’s not my lungs that are pressurizing the air, this is because filtering the air requires additional pressure to force the air through the filter.
- fao_ 7y agoIs the battery for some kind of fan that pulls in air? Presumably any kind of fan would make it difficult to extract the air output properly. You should focus on HEPA compliant masks that make it easier to filter out things, like the Respro series -- however those are not confirmed for use to extract solvents and paints, so that might be worse than no option at all because you could believe that you are protected and actually the mask does not protect you.
- amluto 7y agoWhat you want is called PAPR. edit: Avoiding the extra breathing effort is only part of the benefit. Respirators generally let a lot more pollutants in through leakage than through actual failure to capture them because it’s very hard to make a good seal around your face. A powered respirator can keep the internal pressure neutral or slightly positive, reducing the tendency for anything to leak in around the mask.
