This is the blower and facepiece i jave been issued at various companies ive worked at. Same issues you pointed out are what i had with it. Heavy on the neck noisy, low intelligibility of speech and i dont think it puts out much air. Expensive
It's good to test it both ways. These masks have more moving parts; more ways for it to fail. Testing it off is good because it's a worst-case scenario test.
Could you test the 4 or so P100 rated disposable respirators? The two available ones from the US are the Moldex 4400 P100 and the 3M Particulate Respirator 8293. The other 2 on the Niosh list appears to be hard to obtain. I know their filter medium passes muster (I hope) but I like to see how it does in a QNFT. I see the Moldex 4200 does poorly in your spreadsheet, but the 4400 has full foam and a valve which should get a better fit factor (I hope, since I often use this model). And the moldex accordion design should work well with vertical jaw movement (at least I hope).
Interesting review. My company has been at work on a PAPR that's simpler (all in one design monocoque manifold). Our aim is a PAPR that's more accessible to the DIY crowd. When we have certification, would you be willing to give it a try to compare? Its called MicroClimate Air3.
Sure, I would love to get a chance to test out the Air 3 when it becomes available. I've been following your development of the Microclimate with interest. I've been impressed that you decided to go the extra mile and transition from making a consumer PAPR that was distinctive, protective and fairly priced for what It was to engineering and manufacturing one that will meet the newer NIOSH PAPR class performance requirements and expand your market to include OSHA compliant workplace use, while still at the same time, better serving what seems like it was your original target market of individuals.
I have a CleanSpace2 I'll be testing. It's more affordable than the halo, but not waterproof, and cannot power a full face mask. However, I assume that it will otherwise test similarly. I got a good price on it as a new open box item on eBay, but I have not yet sourced the fit testing adapter necessary to PortaCount test it. The CleanSpace PAPRs are advertised as being compatible with PortaCount testing, so I had assumed that it had built-in compatibility for attachment to the test machine. But as it turns out you have to buy the adapter separately for $$$, the same way it works for many other elastomeric masks.
I'm rather surprised by the numbers. Way lower than I expected. There are all sorts of possible confounding factors, including leakage of the test adapter. So I don't consider any one test, or one person's testing, to be definitive.
What is the connection piece that is on the right side of the mask it looks like there’s an adapter there with another hose not the blower but the other hose connected to that adapter piece that goes on the right side of the mask. What is that called and how can I get one or where can I get one?
It's a 3M fit test adapter for the proprietary 3M bayonet connectors. Get them on Zoro dot com and elsewhere. Pricing was better on Zoro than on eBay, surprisingly, last time I checked.
I've got 3 other to test: CleanSpace2, 3M TR 300, and a Honeywell 700. My preliminary impressions are that I like the TR 300. I haven't used the PortaCount on any of them yet, though.
@@PhattPhillip I'm kind of surprised how much I like it. The effortless breathing and the fogless visor contribute to it. I don't have a hard top for it yet, they are expensive to buy individually.
PAPRs are cooler inside because of the higher airflow, which also prevents humidity build up. I plan on measuring and quantifying the heat and humidity in different types of respirators in future videos.
Can you recommend any air filtration product that does not have anything blocking the view ( like a nose “cone”), allows glasses to be worn, has a seal around the entire face, and is light weight? The seal does not have to be airtight around the neck. Lots of requirements. When wood carving, I have to bend way over to see past the nose cone on half face respirators. Most respirators do not allow a comfortable fit for glasses. No matter what glasses I wear, wood particles, float up behind them, or around them or over the top of them and get into my eyes. Goggles do not allow for glasses to fit under them. Any ideas?
A "loose fitting" PAPR will do all of that. Full face protection from particles and debris - including impact protection. You can wear your glasses normally without leaks. No fogging or humidity build up.. No breathing effort needed. I've seen more and more wood workers wearing them for all day protection and comfort. A 3M TR 300 with a M 206 hard top is one of the best options if you need just particulate filtration. If you need chemical filtration (for painting or other VOCs) you'd need a TR 600. (Some of the hard tops cost more for features you may or may not need. The M207 is heat resistant, that M307 has a rated hard had for working construction) The 3M TR 300 is sometimes under $500 on Amazon, but only with the soft top. The hard top can be bought separately, but is always >$250. The MSRP for the 3M PAPRs is really high, though. I've also seen some woodworkers wearing cheaper alternative PAPRs that put the blower and battery on your head that are less comfortable and not NIOSH approved, such as the Powercap and Trend Airshield Pro, but I haven't used either of those and can't vouch for them.
@@jellyfish2b Yes, with the VersaFlow PAPRs, it's a system. You need the belt pack with the blower and battery and filter, the connecting hose, plus the head top of your choice. Having a hose and a belt mounted blower makes it seem cumbersome. However, It makes the head top much lighter than if you have to wear the blower and battery and filter on your head as in some of those other units I mentioned. Another advantage of having the belt mounted blower is that it helps keep your filter cleaner. It's not right above your work piece, it's behind you typically, so you're going to get less sawdust into it.
Even if they didn’t have an air pressure sensor, surely they could’ve added a fan speed sensor? Most computer fans have had speed sensors for years, so I really feel like they don’t have any good excuses. Thanks for the comprehensive test. Can’t imagine using something so noisy even if I was alone. Please don’t test a Versaflow PAPR unless you know it’s going to be extra noisy. I don’t want to be tempted. :)
Doh! The Versaflo TR-300 is my favorite, and is much smaller, quieter, lighter and more convenient than I thought it would be. And there are some good deals on them on eBay. I got a new, open box one for way less than I expected (I wasn't interested in used ones, because they could be covered in all sorts of toxic chemicals from being used for remediation and who knows what else). I'll have to check on what happens when air flow is restricted to the blower for the 6800 PF. With the TR-300, air pressure automatically increases to try to keep the air flow rate up. It is self-adjusting for altitude, as well as filter loading. I don't think the 6800 PF has any of that, I couldn't find it in the literature. Whereas it's a selling point for the TR-300.
@@swes2934 I would love to give more information on fit for elastomeric fit, but it's difficult because sizing isn't standardized. I had to take a guess when I bought the medium size 6800 mask, which I found described as fitting "most" people - I often take a large in a half face mask, so I was reluctant to buy the medium size for the full face, but it turned out to work well. I couldn't find actual facial measurements to correspond with the claim that the 6800 fits most people. However, the good thing about full face masks, is that the shape of your nose doesn't matter. That takes one of the variables that makes half masks tricky to fit out of the equation. You also don't need to consider face size when it comes to loose fitting PAPRs, such as the head coverings, both soft and hard, that are typically used with the 3M TR 300. They are not designed to fit tightly, and there is no seal to check. They rely largely on the air pressure from the blower to keep contaminated air away from your breathing zone. The head coverings are based more on head circumference, to make sure that the harness inside the head covering will fit on top of your head well. It's more like hat fit, than mask fit. And the harnesses are adjustable, like the harness inside of a hard hat. I will try to include more information about sizing going forward. I do tend to mention that more in my videos about N95s and other filtering face piece respirators, because my high nose bridge makes it hard to get a good fit with most N95s.
Surgical masks leak around 50%. They are not tight fitting, nor are they meant to, and are not considered respiratory protection by OSHA. The fact that OSHA does not consider them respiratory protection makes them especially convenient for employers who require their use because even when required for employees, that does not trigger the fit test requirement needed for mandatory respirator use, such as for N95s. Since they aren't respirators, they don't need respirator fit testing. But it does not protect very well. Not a good savings. (Voluntary use of N95s in a workplace by employees does not require fit testing, but fit testing is required when they are mandated by their employers.)
@@gerardhughes, thank you! Pretty useless for immunocompromised in hospital/healthcare settings, but that’s all everyone is required to use… for now. The smart people use 3M auras or better. Thank you for all of your reviews. They are extremely helpful. ❤️

@@gerardhughes Amazing! Looking forward to your video on it!
I was expecting higher fit factors from a full face. Suspect there is a small leak around the edge?
I'm rather surprised by the numbers. Way lower than I expected. There are all sorts of possible confounding factors, including leakage of the test adapter. So I don't consider any one test, or one person's testing, to be definitive.
Leakage of the fit test adaptor should be easy to check. Have you tried it on a half mask with p100 filters?
What is the connection piece that is on the right side of the mask it looks like there’s an adapter there with another hose not the blower but the other hose connected to that adapter piece that goes on the right side of the mask. What is that called and how can I get one or where can I get one?
