Surely everyone already knows that an ordinary medical mask is a very unreliable means of protection against virus infection. Air chooses the path of least resistance, and most often this path runs through the cracks between the face and the mask. In addition, exhaled air moisturizes the surface of the mask, which creates an ideal environment for the survival of microorganisms.
Based on the foregoing, a respirator with an intake and exhaust valve was designed and manufactured: • 🔅 DIY Respirator from ...
However, some weaknesses were identified in the first model. In particular, the mask body did not retain its shape, which is why it had to be pressed harder to the face. Valve throughput was low for quick walking or running.
These flaws were addressed in the second mask model. If you have any questions about the design of the mask, I will be happy to answer them.

The valves are a great contribution to the homemade mask discussion. Filter cartridge medium could be improved to include activated carbon and commercial air or vaccum filters.

@peter4210 4 года назад

Correction to original comment due to new knowledge: a vacuum filter and some commercial filters will do the trick if you take care and clean them after usage so you can reuse them and it is better then using random pieces of tissue but they cannot filter out viruses at 100% adding activated carbon to the filter will increase the efficiency but activated carbon reduce in efficiency over time as well a become bacterial colonies. they eventual become deactivated. Unless you can reactivate charcoal or clean the other filter materials, or even know the proper protocol to use a mask and not contaminate yourself anyway. Not wearing a mask is safer because you wont be over confident and expose yourself more then what you can deal with

@peter4210 4 года назад

@@xbugz3579 The SARS-COV-2 virus could be airborne with out the assistance of particles. Secondly water is a fluid, one that can evaporate quickly in our atmosphere. If your wearing a surgical mask, and you were lucky enough that the infected droplets did not go around the mask and into your nose/mouth and actually stopped on the fabric, you now have infected water in the fabric. That fabric was designed for the doctor not to spit on your wound during surgery and not to be worn all day against infections. Trough you breathing, the water will eventual be pushed trough and into your mouth/nose or the droplets will dry out, leaving only the viruses in the fabric to await a strong inhalation. Mask and gloves work in hospitals because the doctors and nurses fallow strict procedures to make sure they take out the gloves and swap the mask with out making contact with the infected surface. They also swap them frequently. here in Canada they are investigating way's to reuse that equipment due to the international covert war to hoard the resourses. But The average joe is too misinformed to know any procedures. That is why you either wear the right stuff and take care of it properly or you don't. Over confidence is more dangerous then not having a mask as staying 3m away from people.

Change out the paper towel filter material with 3M Filtrete filters used for the home. Use those rated for MERV-13/MPR-1900 or higher. Rated by 3M to filter down to 0.3 microns (same as an N95 mask but just at a lower efficiency rating than a proper N95 mask, ie. a 3M MPR-2800 Filtrete filter is rated at around 82% efficiency).

@jazztocountry1047 4 года назад

To improve the filter you might try a salt impregnated paper coffee filter. The coffee filter has small press but not quite small enough. The salt impregnation both fills the pour slightly and it also has an attractive quality for small most particles. Another potential filter is to use a hipaa filter paper.

Lovely idea, especially using recycling material as the base, however, those 'filters' won't do much for Viral or Bacterial problems - for those I'd suggest getting filters for Heaters or other devices that can block 99.97% of particulates, MERV 16 are expensive but 1 filter can make multiple mask filters for example. Those will, however, work for dust and such, which is a nice thing to have for environments that have sanding and the like.

@IurisWorkshop 4 года назад

Many people recommend different filters, but few have tested them. Basically, everyone relies on information from the Internet, which can not always be trusted. Based on the fact that every second doctor has already become infected in my country, I have already begun to doubt the reliability and official information. I am preparing a laboratory experiment to test different filters for masks. True, the work dragged on a bit, as it took to build a sneezing machine. Now I’m thinking how to adapt a microscope to this design.
