Donning, fit-checking and doffing the 3M 7500 series half face respirator for COVID-19 management 

Paul Martin Yes the naysayers seldom seem to acknowledge that using these devices spares hospital resources.

Yes these respirators have so many advantages. They are more comfortable especially for long periods IMO, superior fit, superior filtration if you have the P100 filters, and they last a long time if taken care of. Just overall a far better long term solution than disposable respirators.

Ouch, $150! Really, totally worth it no matter what! For cats sake, you are so smart! I mean I figured it out a while back from research and I can't believe the drivers I see without gear. I worry after them. Every single morning I get up and drive to every store that I can to get disinfectant wipes or spray for UPS, Amazon, and USPS. Love to drivers everywhere 😘😘😘

6200 mask is 27usd' 7502 mask price is 48usd

@@stacyjaye6350 I think the $150 is for the full face mask. That is a reasonable price for that, they are actually more expensive I think. However if it's the half face respirator, then yeah $150 is a TOTAL ripoff. I know they are hard to buy right now but $150 is way above the normal price of around $40.

I am afraid I don’t. You would have to try them. If you are operating, make sure you cover the exhalation port with a surgical mask or some such device.

Iam dentist, use respirator

Jose Luis Avila That’s the North American version of the 6038. Good to go.

It is the same only different model number because one is NOISH certified P100 and the other is EU certified P3R. They should have the same spec.

Orhan Semerci I am given to understand that the full face as purchased is not compatible with glasses frames. So you would need to either wear contacts or find a solution for some kind of sports strap instead of frames. The half face with a 6035/6038/7093 meets P2/N95 with a half face respirator and meets P3/N99 with a full face respirator, according to the 3M distributor I spoke to.

@@staffnsnake Thank you doc

Not a doctor LOL. Got the 3M 6200 with the p100 OV filters. I wear 3M safety goggles over my prescription glasses, I also got a shower type bonnet cap. Oh my god it feels so good LOL!! Peace and love from Tulsa Oklahoma handling the Sara Lee bread!!☮️💖🇺🇸👢

I guess that depends on what you are doing. If you don’t have the virus but you are certain (through testing) that the patient does, then for your own protection the surgical mask is not warranted in addition to the respirator. But if there is any uncertainty that the patient might not have covid, then the risk runs both ways: you could have caught it and be asymptomatic but still spreading. In that case, the exhalation port needs to be covered. I want to make an important point. These 3M systems were adopted as an emergency measure in the absence of (or insufficient quantities of) correctly fitting N95/P2 particulate respirators or PAPR systems. It was never the intention of 3M, nor is it my intention or expectation, that these form a permanent part of medical management, given the potential risk of spreading the virus from HCW to hitherto uninflected patients.

I have not seen the other models although I understand that the elastomeric (rather than silicone) can also achieve a good fit. If I were in your position I would contact 3M in your country and ask.

is the doffing procedure really this simple? as been shown at this video at 9:16 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mP2xgxAOaPk.html

linnen_elm the 7093 is the US version of the 6038 so all good. Do not spray the black side. Wipe down with an alcohol or antimicrobial wipe. You must not get moisture on the filter surface.

@@staffnsnake Oh my, I accidentally sprayed it once sometime ago, I'll be careful next time. Thank you so much~

Saturate a piece of paper towels and wipe it instead.

brian wee Might I ask why you are wearing a respirator at all? These videos concern aerosol protection while working closely with medical patients as opposed to wearing one in the community.

I have one to protect me from dust and paint. And the current threat of Covid in my community, I plan to use this once we get back to work in a week's time.

@@staffnsnake Same deal with me. I work in the paint industry and already have a lot of supplies from my work. I had all the N95 masks, half face respirators, full face for working with fumes, dust, and hazmat, the original purpose of these masks. Wore them all day for nearly 7 years now. Now they're just double purpose, and if they work well for being close to patients, then they work for protecting in crowded places. I realize healthcare workers are at risk, but those who already had them should not be shamed for using them to protect themselves. A life is a life, and these could be a life saver even for average people out in the community who have them. Cloth masks are a 'collective effort' and we are seeing a lot of stubborn people not following that. I have to deal constantly with people who do not social distance, wear masks, or take any kind of precautions. So protecting myself is just the right thing to do, one less patient for you to deal with!

I cannot say what the best thing is. My only purpose in making these videos was to review emergency use of 3M respirators as has since been reviewed and approved by the CDC. For flights, I would wear a disposable N95 respirator. Take a few.

So long as you have the particulate filter attached, that will filter virus. You must be sure not to touch the outer surface of the filter. Unfortunately there is a large hole on in the particulate filter holder that allows just that. So you need to be very careful. Some people have made 3D printed covers for the hole. You would need to search for them yourself online. You would be better to find and order a specific particulate filter like the two that I mentioned.

Thank you, Doctor! Yes, I have the particulate filter attached with a plastic retainer that 3m makes. I’m glad you think it’s a good set up for a COVID prevention. Take care and thank you so much for All you’re doing.

@@lifeafter6030 It’s not what I think, I’m just repeating what 3M says.

Hello do you have the 7501 meaning small? My facial sizing is smaller than a man's : eyes to chin 10.5cm and lips 5cm, what are you measurements?

Yes the 7501 is the small one. And yes the 7093 works with that.

Miguel Angel Arcos Muñoz Our COVID intubation team uses them as part of a Discord chat in case we cannot be heard through the respirator. It’s especially useful as the scout in the anaesthetic bay can pre-empt our requirements without poking their head through the door and exposing themselves to increased potential aerosol risk.

@@staffnsnake How does it work, do you put a microphone inside the mask? How is communication established?

Miguel Angel Arcos Muñoz The microphone picks up both sound and vibration. All hearing is from bone conduction via the zygomatic arch. It works quite well with a respirator on. Communication is via a groups chat on Discord.

No because the filtered surface is not exposed to light.

Jeremy Young The white plastic soap bar filters can be easily wiped clean and are good to reuse for months if you look at the other videos by the same author

Yes the filter does filtrate virus particles. From what I understand from 3M’s literature, the virus particles remain trapped on the outside of the filter, yet under the plastic case. The virus would not remain viable for long. But as long as the filter within the cartridge is dry, there is no reason to suppose it would somehow let them through. Also, viruses are not bacterial biofilm and don’t work their way out to the outside.

Fabian Galarza I cannot speak for the half face 6000 series but there is literature online from 3M showing the differences.

@@fabiangalarza7782 so you don't breathe on your patients when doing invasive procedures.

don0giorgio I’m afraid I am not an authority on this. I just made the videos to communicate what 3M published. I would think that spray would have trouble getting into all the nooks and crannies.

@@staffnsnake well im not working with patients, just going out of the flat to buy food etc, i hope generous spray of 80% alcohol will do the trick)

@Andy Seemite You can spray into a filter? I thought (from what I have been researching) ppe companies , in general, state to NEVER clean the inside of a filter or get it wet with anything / spray anything into it.

I don’t know what language this Cyrillic script represents. Sorry.

Nobody sought TGA approval because optimal protection for doctors and nurses directly involved in Covid airway management is not able to be provided by most health services, due to supply chain issues. Essentially, until the hospitals have access to medical-grade PAPR such as CleanSpace Halo (and nobody is saying it is their fault that they don’t), then most of us respectfully don’t care what they think - we will protect ourselves and also ensure that patient care is not compromised. Some 60 doctors have died in Italy, largely due to high viral loads encountered from close treatment of Covid patients. While health services have a duty of care to workers, their inability to manifest that does not remove the right of individuals to see to their own care. The contact via 3M was regarding the filtration properties of various filter cartridges. This is an emergency measure that some have chosen to undertake during a crisis. We hope we won’t have to undertake it for long.

You can DM me at staffnsnake@gmx.com

thewhitewolf If you can find a supplier of PAPR such as CleanSpace that will actually deliver, let me know! As for the filters, 3M distributors get them in small batches as released from 3M’s centralised distributors. It’s a matter of luck.

@@jakeangeles9120 thanks

@@staffnsnake I have had success with a PAPR purchase from Ebay. I now use my C420 PAPR with a gas mask every day / all day at work (office computer work / some warehouse work). PAPR sure helps make breathing easy. Just a question, are you a doctor? Also (for anyone who is doubtful or not confident enough) would you agree that wearing the best personal protection equipment while working in ANY OCCUPATION is a huge step to reducing covid 19 outbreak? I think at this point, of course medical workers, first res-ponders, etc... need PPE gear such as face respirators, p3 / p100 filters, PAPRs, etc.. However people that still need to work in an shared space / shared office environment should also consider wearing PPE all day at work. I have received many compliments from random people, when I am out with my gas mask and p3 filters.

@@thewhitewolffl I do the same. I was lucky enough to work in an industry that had all the 3M equipment because we used to sell it, then it was written off and they let me have it before the pandemic started. So I have all the respirators, P100 filters, full face mask, etc. Had a ton of disposable N95s. You bet that I use them and am not ashamed to use them. My parents live in an other province and comment that they have heard all the stuff how the public shouldn't wear these things because there is a shortage, etc. Well, this is my own stock. I know it is all sold out because I have looked out of curiosity! It is crazy how inaccessible it is right now. I'm still using it for myself, call me selfish but if I don't get infected then I don't end up infecting others of burdening the healthcare system either. We were also lied to at first that masks don't work. I never believed it. Governments, etc were not honest with us because they knew they needed this PPE. Well, I don't want to die, I have athsma, so I use it without shame for myself.

www.3m.co.uk/intl/uk/ohes/segments/healthcare/(9666a)OH_ReusableTechBulletin_lft.pdf As 3M half masks are reusable, one mask can be issued per worker per pandemic wave. 3M™ 6035 P3R filters are also reusable, and one pair is considered to have enough capacity to last a pandemic wave. When compared with disposable respirators which are discarded after every shift, or between patients, total product purchase costs for reusable respirators are likely to be considerably lower.
