@Fact Checker There is a filter on the exhale valve that should reduce the risk of contamination but only in part.

Fact Checker Not correct. The filters are 99.97% effective and if you don’t have COVID you can’t pass it on.

d1v1s1onby0 Yes I have removed them. The package often comes with two pre-filters in it for just that purpose. But compared to the 6035/6038/7093 enclosed particulate filters, they are just not as safe for our purposes and I would only use them as a last resort, given how tricky they are to clean.

5n11 cost about $18usd for a box of 10(5 pairs). Much cheaper to stock them as single use vs 2138

@@Rondoggy67 The surgical mask overlay is for protecting the industrial filter cartridge from absorbing splashes and propelled droplets since surgical masks are hydrophobic.

@@meleagrisgallopavo6904 couldn’t he buy other filters lol

Not save in the slightest. Dentistry procedures are aerosolising, often, for which you'd need maximum PPE / filtration. You should be worried about the air they contaminate and infect you. Are you really a dentist with a medical background / training in viruses / infections?

No, we use sodium hypochlorite, aka bleach, to which the virus is especially sensitive.

SKMatoBB Because if they are spoiled by droplets then they become an infection risk. 3M pointed that out in communication to the rep I get them from.

@@staffnsnake But that's only because of the textile nature of the filter and the fact that it's surface can't be disinfected like the other filters with a plastic surface, correct? If you don't touch it with your bare hands for the 72 hour duration for which the virus can be alive on the surface after each use, it should not pose any risk and protect you pretty much until it's clogged up by dust and other particles from the environment, right? You just have to be careful not to touch their surface, transfering the virus to your hands and then to your body through your mouth, eyes, etc.. I think it'd be pretty wasteful to just throw these filters out after each use, wouldn't it?

@@staffnsnake Why would the droplets damage the filter any more than any other particulate filter? The inside of these disk-type filters has pretty much the same structure as the replacable pads that you put underneath the cover of the plastic filter. Making the only difference between them the nature of the surface of the filter as I described in the previous comment.

SKMatoBB I guess it would depend on how soon you expect to reuse the 2138 filter. I also suspect that most hospitals would take a dim view of ever reusing any kind of fabric equipment that had been soiled by patient bodily fluids and not actively sterilised. Moreover, there are other pathogens besides SARS-CoV-2 in pharyngeal droplets. I need to stress that the whole exercise of using these 3M respirators is for while we await arrival of medical grade PAPR systems. This equipment is not the plan, it’s the fallback from the main plan.

@@staffnsnake I was talking from a public standpoint, not about hospital use per-se. Mainly about using it for shopping and other necessary activities requiring contact with other people. This is the use case that I'm considering for these filters. Do you think they'll suffice for re-use in these circumstances?

That filter shown here (plus pre-filter) is a vapour filter that absorbs formaldehyde among other organic vapours. So it would present the same issues as the regular paint vapour filter plus pre-filter in that it is difficult to keep clean. The 6035/6038/7093 are better because the filter is completely encased and droplet-resistant, whereas the setup you mention exposes the pre-filter to droplet contamination.

Using a steamer might be better option*

theoretically yes. but its possible that particles went deeper into the filter fabric and might not be reached by the UVC. but UVC will surely kill off everything on the outside. if you have to reuse them, than exposing it to UVC is surely better than nothing.

Excellent point. I recommend a slightly different way, which is to use a suitable disinfectant to wipe down the outside surfaces, including around the cartridge interlock area before removal. Then remove the cartridges, and then wipe back side of the cartridge mating area. Put these aside to dry and for safe keeping. The half face or full face mask should be decontaminated following whatever procedure your local officials are comfortable with. You do need to clean these, as your own resperatory droplets will make the inside kinda funky. The straps also could potentially transfer the virus to other surfaces, not to mention any viral particles you had stuck to your face (but not entered into your body) can be transferred onto the mask as well.. 30ml bleach + 7.5l water, TBquat, or virkon 1% are all acceptable options. Each option has specific steps and times to follow. All require a final rinse of clean water, and then allowed to air dry.

No you must remove the filters for cleaning. You don’t have to worry about possible entry points for the virus through the filter aperture. They have static charge and could not reasonably be expected to fall off the plastic housing and into the wearer side of the filter. You must clean and decontaminate the respirator after use.

it's the same as the 6035 but it adds chemical filtering the 6038 weights a bit more but it still provides the same protection and P3 level of filtering

@@arangaran Thank you for the information, good sir!

P100 filters don't filter out vapours, so yes, you should still be able to smell ethanol through it. However, do ensure that the filter is properly screwed onto the respirator body.

No you shouldn't be able to smell anything!! I can't even smell gasoline or garbage with mine.. smoke? Nothing. N95 or P100 you should not smell or taste anything

Eleanor Robertson Hello Eleanor, this video is not representative of any particular hospital. I work at six different hospitals. The other video I posted on my channel demonstrated 3M’s decontamination protocol for enclosed particulate cartridges and respirators. I made no claim to what any particular hospital does in the event that they purchase and control their own respirators.

How difficult / easy is it to breathe with one of these on?

7093 or 7093b/c are USA equivalents , try eBay

Are you wearing coveralls as well? I work at a different department in Sydney. We appear to be going down the surgical gown/balaclava route for neck coverage. At what point are you cleaning and wiping down the mask? With the coverall still on?

Michael Tobin We are using gown/balaclava or the coveralls (being careful to ensure hood doesn’t contaminate your back when removed). What we will be using will be based on what’s available I think as we’re running out of everything. The respirator is cleaned as the last step, while still on, using antiviral wipes (eg. Clinell wipes) in front of a mirror to ensure good coverage. We’re using sealed cartridge filters and not removing them, just cleaning all external accessible surfaces. So far so good.

Hi Michael (again) and nice to meet you Paul. I would not recommend a simple wipe if you have been involved in directly intubating a covid patient. But if you were just wearing it for general use while transporting a patient or in an ED red zone, perhaps it might be okay. I couldn’t say. Here is a link to 3M’s literature on use of their respirators during an influenza pandemic www.3m.co.uk/intl/uk/ohes/segments/healthcare/(9666a)OH_ReusableTechBulletin_lft.pdf

@@jasong9502 yes, which is why I am using it working at the hospital with CoViD-19 patients in the respiratory ICU, and with trauma patients under investigation for possible respiratory disease.

Ryan Snyder I have been looking at people do that around the world for many weeks now. How do you loosen the straps to safely doff the snorkel mask?

Ryan Snyder And there are lots of Ryan Snyders broadcasting to RU-vid. I cannot tell which one you are.

Irish Valina They are the North American model number for the 6038 so they will be identical. They have different numbers because they are tested by different statutory bodies. In the case of the 7093 it is NIOSH.

Hola the 2097 its good to the covid-19? , gracias!

Where can I buy my filters anyone know a website

@@moeroberts3663 ebay has 3m 7093cn for around $30 a pair

staffnsnake thank you very much! Let's all be safe while attending to cases.

Jonathan Rodriguez what type of filter. The cartridges of the 6000 series are only vapor filters and not for particles. You need the 5n11 attachment

Jacob Clark It isn’t an hypothesis, it’s reality. There is no filtration or exhaled air. If you are doing anything invasive for a patient with a reusable respirator, you *must* cover the exhalation port with a standard surgical mask.

@@staffnsnake thank you very much. Look like new York is a total nightmare at 21℅ . in Florida the death's are going to be unbelievable, with So many elderly. I just wish I could have saved them. People should have repelled as a magnet get in get out, every one needed a mask So they did not spread it , with out that you need a reusable cartridge type full face mask to be safe at 6 feet away. Florida is acting like they can have a convenient pandemic with opening of Walt Disney talks. Florida is taking like the numbers are going down when they are about to skyrocket with out of control like new York. You can't change what you don't acknowledge. Those who don't study history are about to repeat it. They thought the dip in cases was because of distancing instead it was mainly caused by temperature changes.

@@staffnsnake Aha! now I get it :)

Good Cats - No Adverts where can I buy filters

Yes there is a worldwide shortage of PAPR sets, which is what led me to investigate these respirators.

​@@staffnsnake , you can try ebay for paprs, new used and NEW OLD STOCK

Fumes are a totally different thing from particulate or droplets, so yes it's fine. P100 are not supposed to filter odors.

Similar. P2 filters 94% of 0.3 microns particles, n95 filters 95%.

C C Yes they will.

@@staffnsnake aren't the 6038 even better than the 6035?

@@luke11986 Not for this purpose. The 6038 also filters some “nuisance gases” which are not relevant to particulate filtration.

@@staffnsnake Thank you very much for the quick reply! Wish all the best

Good kit!

You have to dampen your goggles with soap solution and let it air dry. It won't fog if you do this before every use.

Yes 7093 is good also are 2097 filters they work great if you working were nothing smells bad rotten like maintenance I would use the 2097 it blocks organic gas amongst others nasty smells and yes it's a particulate filter so it blocks covid also

Honestly look into buying air filter that will never fog up and keep you cool

P100 is the same as P3 and it will work well for stopping SARS-CoV-2 ; remember to do a 'fit' test to make sure there is a tight-seal on your respirator ( buy a respirator made of plastic and rubber/silicone, not a paper-type mask, then you'll get a good seal ).

Joe Luis all the 3M filters I reviewed have compatible bayonet fittings.

They're brand specific. 3m only fits 3m masks. Msa only fits msa masks, etc

Not really, as far as 3M tell me. But they usually throw the filters out after a year so there is that

A half face respirator with P3 filters. Whatever respirator get P3 or N100 or P100 filters for maximum protection!

Depends on size of your face. Try a medium and go from there. Follow the 3m training videos

7093 Gang FOR LIFE!

I have read that the filter has to be 7093C (technical sheet of the filter). Do you have more information about de 7073

7093 works as well. But it doesn't block any smell. The 7093c blocks the virus and the smell too.

Lissmirelle VA Why would it need to be 7093C? The C model is for nuisance gas. All you need is the filter (7093 or the European version which is the 6035).

Rodrigo Arroyo I believe the 7093 is the same as the 6038, so probably yes.

@@staffnsnake thanks for the fast reply Greetings and be safe 😁

I am using the 7093B

P100=p3

Don’t get the 7093CN. This means it’s a Chinese version and it’s not reliable. You want to get an authentic 3M product manufactured in the US or Canada.

What brand is the mask and what brand is the filter?

P2 ~= N95. N95 is USA standard, P2 is European standard. N100/P3 are better if you can find them.

I would think not as the light would have trouble reaching the inside of the respirator silicone.

@@staffnsnake thanks for the info

Supposed to be good for 6 months. Check 3m site

Adi Andre I am not a rep or an agent for 3M. I only did videos on them because that was what was available. There are other brand out there like Sundström from Sweden that some are using. One hospital in Sydney has those. So you will have to do your own research on the particulate filtering qualities of any filters you get. If you can, you should also get quantitative fit-testing done for whatever you find. The vapour filter components are not relevant to viruses or bacteria. Cheers

I'd like to chime in here for a bit. Any respirator that pressurises properly works with a P2 or P3 filter. Alternatively you can use military surplus gas masks with 40mm NATO NBC or ABEKP filters which are much more common, cheaper and effective than the type of proprietary connectors you would find on 3M type respirators. Even if the filter itself is expired it retains its particle filtering properties.

@@victigr I have seen adapters to use 3m filters on gas masks. And several other adapters for different countries gas masks to NATO standards also.

Xh1n0 I am afraid I don’t know that number. You should check the ratings on that filter. From what I can see on a web search it looks like it easily meets that standard. Please check with 3M though.

IMO 7093 (aka 7093B or 7093CN depending on the place it'll be sold) is the best (maybe a little bit overkill) for covid-19, but if your budget permits and it's relatively abundant at your place, i say buy a few pairs, much easier to clean and much rugged than particulate filters like 2071, 2097, or similar

First name, Surname From what I can see, that model looks like the 6038 filter in Australia.

@@staffnsnake the difference between 7093 and 6035/6038 is that the latter also filters nuisance gases, therefore not necessarily needed for COVID-19 scenario

First name, Surname Thw 6035 does not filter nuisance gases, only the 6038.

If your wanting to add the P100 filter to the cartridge filter, you can use a GM 502 adaptor that snaps onto the face of the cartridge. It has a male bayonet fitting just like the respirator. Otherwise the P100 pancake filter attaches directly onto the respirator.

It's one use only. Dispose if contaminated I think.

Just leaving them for a few days will Kill the virus, just swap out filters on a regular basis and they last until physically clogged or broke from excessive changing.

Yes. It's the same, just for different markets because usa has different ratings to print vs outside of usa. They are the exact same cartridge though.

Looks like they are the same, 7093 is for USA and 6035 for AU / NZ, probably different regulations. If you look in 3m websites you will find they sell 6035 OR 7093, not both.

The 6035 is the same filter as the 7093 which is found in the US market.

Can u tell if the pink coloured p 2091 filter is suitable for use in a clinical setting. I am an ophthalmologist. I have the pink one... should I continue using it.

It is suitable. I think that has a carbon or charcoal filter included

7093 I think

Dr. Karnav Patel This is because exhalation valves do not have filters when exhaling. It is useful to breath out more easily. So respirators with exhalation valves can protect oneself very well but are not designed to protect others or the sterile area. Its better to get a resiprator with non exhalation valves.

That is a very good point. An option could be to shut the exhalation valve with tape. My concern with that would be whether the lenses would fog up quickly in that situation? What do you think about this possibility? Cheers

@@javierpachonalvarez5757 Exhaust valves also help fogging up less on lenses, so blocking it would increase humidity on lenses and fog them

Hey Ralph! That is my view as well. In order to avoid the fog, the solution proposed by Staffnsnake is to cover the exhalation port only with a surgical mask so that there is still some airflow allowed; However I struggle to understand how the fog wouldn't be an issue in a full face respirator with the exhalation port covered with a surgical mask, as the airflow rate coming out would still be greatly reduced/restrained....It would be great if someone with a full face respirator could actually test it to clear all doubts. Cheers

Use 2097 filters

Cite source?

paper or non-woven fabric bags is better (breathable). Locking in the moisture means mold growing conditions, also virus lasts longer in humid environment. if using ziplock bag, add in dessicant. Silica sachets that come with shoes, handbags, you can dry at a low temp in an oven and reuse.
