They will truly protect you from the virus and they are much easier to breathe through than a cloth or surgical mask (they are designed to allow you to maintain suitable oxygen levels).These are serious products.ĭue to federal law, some airlines won’t allow these respirators to be used on planes because they protect you, but they don’t protect other passengers since they aren’t filtered for the exhaust. These respirators make it easy to both inhale and exhale. For heavy-duty use, the 7093 filters are larger and more expensive, but more durable and last longer (you can wipe them down if they get dirty). You’ll need a 3M brand P100 particulate filter, such as 3M 2091 to protect against COVID.

Tyson did an excellent video series on showing that masks don’t work which you can watch here : Petty has a Rumble channel of his videos. Their PAPR system is used with a P3 particle filter so they are getting state-of-the-art protection for their workers. Check out that page for how they came to their conclusion. This is what doctors at the Imperial College in London use to protect themselves against COVID. If you want PPE that seriously works and would protect you against viruses and asbestos (which is much larger than the virus), you’re looking at a properly fit-tested Powered Air-Purifying Respirator (PAPR) which has positive pressure. The only real solution is engineering controls, something the CDC never talks about. This is why all the clinical studies show 0 difference in the number of people infected. What this means is that with any of these interventions, you’ll be exposed to slightly less viral load which means slightly slower onset of disease (delays maybe in hour best case (assuming a 10 hour doubling time).

This is useless to protect against COVID because of what you are typically exposed to which is measured in orders of magnitude. Watch this video which points out that even properly fitted N95 masks will be <50% filtration of particles 1um in size (10X bigger than COVID) and for cloth masks 9.8% and surgical masks 12.4%. PPE is the last line of defense, not something to weigh heavily in a proper mitigation effort.

They always emphasize the hierarchy of controls and that the focus on PPE as the silver bullet is misplaced. Stephen Petty and Tyson Gabriel are the smartest guys I know when it comes to industrial hygiene (mitigations including masks, HEPA filtration, etc).
