Try the 3m 7093 niosh rated filter. It’s specific all for medical.

You should try and use a 3M 7093 enclosed P100 cartridge. They are used in Africa for responders to ebola. This is because the filters are enclosed behind a plastic housing which covers the entire filter. So there were able to just wipe down the exterior of the cartridge and were not forced to replace filters over and over. One filter will last according to 3M, “for the duration of the pandemic wave.” Realistically it should be good for a year or more. I used one for my geology thesis sample collections in asbestos mines. Works great.

I would wipe the filter at the end of the day or intermittently with an alcohol pad. It didnt over dampen the filter. Then I left it in a brown bag or out to dry

@@calincalabrese6260 alcohol is super bad for the filter if it touches the filter material at all, you should consider replacing them quickly. Your filters are made of melt-blown (MB) stretched polypropylene that use electrostatic charges to pull dust and virus particles in and stick to the filter. Alcohol rapidly degrades MB polypropylenes charges. Here is a scientific paper which was published this year in journal Applied Nano Materials, where they tested cleaning your filter material with ethanol (alcohol). This is a quote from their findings in the study: “We found that the filtration efficiency of MB filter significantly dropped to ∼84% and ∼62% after ethanol spraying with 1 cycle and 10 cycles.” Fortunately ebay and amazon still have the 7093 and 7093c cartridges for under $25. :) www.ncbi.nlm.nih.gov/pmc/articles/PMC7323055/#!po=0.877193.

How are do you filter the exhalation part? I dont want to wear a surgical mask over it but all the air I exhale is unfiltered

there are 3d printed filter housing for these 3M half face masks. you can cut out surgical mask/electrostatic hepa sheet as filter

@@calincalabrese6260 hi you can google for "3d printed respirator exhalation valve filter" there might be sellers near you. some even post the raw files online so you can print it out yourself if you have access to 3d printer. i got my 6200/7500 all fitted with those from a local seller here in asia.

Can I use this mask for cardio workout
@calincalabrese62603 жыл бұрын
Yes you can! As with anything make sure you try it out first at a slower pace. The benefit of these masks is their increase in surface area which means easier flows when exercising. Only draw back is you might get looks. Remember after awhile the filters do go bad and typically that shows up as an increase in difficulty breathing with them on. So have some spares handy and switch them out when necessary

Hello Nurse Anesthetist Calabrese, is it offensive for medical practitioners to see ordinary civilian with no job-related reasons to wear respirators like that? Thank you.
@calincalabrese62603 жыл бұрын
I would say its not offensive. Unfortunately people will have their opinions. There were many civilians in NYC at the height of covid wearing these masks. They are very effective and more comfortable than the normal N-95 if worn correctly and with the proper filter. Having a safe/approved vaccine is probably the best option since wearing a mask is not always done correctly and the mask eventually needs to be cleaned and the filter replaced. Hope this helps.
