Please explain the basis for your belief...

Way ahead of the pack flock.

Might help if you mentioned what you ordered....

The 2 Sam's clubs in my city are business as usual. I've been a couple times in the past 2 weeks to top off reserves. I paid attention to people's carts and they are buying the usual junk food, etc. Doesn't look like anyone is concerned yet.

Probably a laughably stupid question, but I don't know so I thought I'd ask.

I have a 3m half mask with p100 cartridges. I was wondering last night about fixing a small blower fan by hose to the inlet of a filter to force air through the filter and into the mask.  If there was enough flow it might make the mask positive pressure which I would think would be advantageous. By connecting the fan before the filter, if anything fails I could just breathe normally with no compromise to the filter.

I work with jet engines so the answer is always more airflow

Edit: I was inspired by This, but I'm suggesting leaving the filter connected to the mask and putting the blower before the filter. Just not sure how well it will push air through vs pulling it.

I don’t know how you’d get it to work with a pancake filter. A cartridge might work? Looks like you need a 3D printer to make the connections.

I have cartidge filters.

I agree it's not a high priority, just thought it might be useful if it wasn't too much trouble to print an adapter. Good point about positive pressure, I don't know anything about that.

Oh well just a thought. Thanks for the feedback!

you dont want soap on the mask when you are done washing.
but yes, that is the standard way to clean and disinfect a mask.
you can use detergent too, they make several specifically for masks, but they get spendy.

I would guess most people in this forum are already stocked up and have accounted for not needing outside resupply for some time.

more important to make sure you have a good seal

Okay, putting this out for input from others more knowledgeable than I:

Q: Would ozone/O3 be effective for disinfecting N95 masks w/o seriously degrading the mask itself? I ask 'cause the wife has a SoClean for her CPAP machine and I was thinking it might make a good make-shift cleaner for our masks/goggles each day. If not I'll resort to open-bagging them aside from the clean zone for a couple of weeks and let nature take care of it while we use spares during that time.

We have a small utility room w/washer & dryer to pass through from the garage to the rest of the house. It occurred to me it might be converted to an impromptu decon station.
Specifically, block off the floor vent, leave the exhaust fan on 24/7 to achieve a constant slight negative pressure in the room. Remove everything from the room not used for decon.
When coming home (gloves, mask, goggles), leave coat in the garage. Remove shoes & spray soles w/70% alcohol. Leave shoes in garage.
Enter utility room, everything but gloves, mask, goggles goes into washer w/detergent & Lysol Disinfectant additive.
Mask/goggles go into SoClean?
Spray gloves w/70% alcohol or wipe down w/Lysol Disinfectant wipes, carefully discard into covered bucket. Clean hands w/hand sanitizer.
Thorough shower.

In the morning, garage would be entered from the garage door via the keypad (after donning fresh gloves, mask, goggles), shoes & coat retrieved w/o entering the utility room.
This is just a rough plan, I welcome any constructive input on how this might be improved. I have no illusions that this setup would eliminate all possibility of contamination but am hoping to reduce the odds of such.
Thx!...

My first thought is if in the increased rate/pressure of flow through the filter would reduce the filter efficiency.

A filter designed to handle X negative pressure from the interior may not perform the same when exposed to Y positive pressure from the exterior.

Not a maskologisurgionaut.

This thread is for prep discussions redirected here from the GD thread, no?

That's what got me thinking about this. If the airflow is high enough, filtered air would leak OUT of any gaps instead of letting any outside air out.

Just a random shower thought lol

This is the kind of thing I'm wondering! I can fan up a blower easily enough, and it may filter smoke smell fine when I test it, but is the filter compromised and I don't know it?

Just recalled from microbiology class that the autoclave temperatures and pressure are to ensure all living microorganisms are killed off.  This includes spores and those microorganisms with thick capsules.

So, while the Instapot method may not be quite up to to autoclaving standards, if it's the virion particles that we want to deactivate, the Instapot may be enough for just that purpose.

As mentioned in the other thread, Bubba's Autoclave. Also makes and cans food (my primary use).


ETA- up to 15psi/250F.

Should work plenty well on this beastie. I actually suspect that this virus is nowhere near as difficult to kill as tough bacteria like spore formers.

See other threads here somewhere, working on it now with good results.

Looking at the Home-D website...

The 6 qt Instapot draws 1000 watts

The 6 qt Zavor draws 110 watts

Seems like the Zavor would be a lot easier on a genny or solar, or is the spec for the Zavor incorrect?

My search showed 1000 watts

Thanks!

I can't find anything relating to the mask's composition on the 3M packaging or documentation. Shucks and other comments.
I know ozone degrades quite a number of things but am hoping it's safe for mask use since it's safe for constant CPAP sanitation.

The sun degrades plastics also.
I have been using ozone for years in our medical practice and have never had someone bring me a broken plastic device.
Use it in my home also.

Stumbled onto this as a possible sterilization tool:

man... where did you find the wattage of the 6qt Zavor?... I even looked through the PDF manual and could not find the specs...

Typo, should be 110 VOLTS instead of watts?

I am prepping to BUG IN. hunker down with the fam, with my Bug out SUV ready to go if anything goes south near me.

I am most worried about food to last until "a vaccine" is made and produced...

m95 made of...

Thx!

And shucks, the Polypropylene filter material is on the "ozone eats this" list.
I have to wonder, how much ozone exposure to cause significant degradation. Hmmm, maybe a test is in order...

Searching for med preps to have on hand in case of infection.    Any list made up yet?

everyone's p100 or n95 and mask cleaning concerned as far as it goes it seems.  I want to acquire oc drugs for potential infection if its the smart thing...  I mean, if the pneumonia or drastically worse conditions set in IDK but this is where I'm lacking mostly.

fever reducer
anti-diarrheal
cough
hydration

....?

Phenergan?
Is throwing up going to be a issue? I keep some in my preps.

Indeed, and a fair question from that perspective.

Any and everything's fair game as far as being prepared goes.  Assuming good health, all we really need to survive are air, water, food, and protection from the elements.  Everything beyond that is just a matter of what degree of comfort you want to maintain during an event, and for how long.  So if it's something you use in your everyday life, it's worth considering how long you'd want to go without it and how feasible it is to build and store a stockpile.

A lot of people overlook the fact that it can actually be more efficient and economical to operate from a stockpile of everyday items instead of adopting a "just-in-time" (JIT) attitude in your own shopping.  As a simple example, take everyday canned corn.  Around here it usually runs about $1 can.  Say your family uses three cans a week.  If you just pick up three cans a week on the way home from work or whatever, that's about $12/mo on corn, or $144/year.

So now you're Joe and Jane prepper.  Rather than picking up a few cans here and there to meet the demand, you wait for a big sale and spend fifty bucks on corn when it's 3 cans/$1.  That's 150 cans - your entire year's supply at a fraction over one-third the normal cost ($48), and you even have six cans left over.  So your stockpile is gradually growing, and you've also got $94 left over to spend on other stuff!  Pretty sweet, eh?

Multiply that by bars of soap, toothbrushes, toilet paper, ketchup, paper plates, deodorant...  the savings add up fast - fast enough to justify retrofitting and extra room or basement or garage into a storage area (storage space is something you do have to think about with this model).  But if you've got the space, it really doesn't make sense not to do this.

Oh, and then, of course... you've already got damn near everything you need already onhand should a situation arise where you can't make it to the store for an extended period.  Ice storm, blizzard, localized flooding, tornado - COVID-19 - you get the picture.  But even without a catastrophe, it's just nice not to ever run out of anything.  

Prepping isn't stupid, it's smart.

NBC news just had a segment on about the wu-flu...

Expert said masks are mostly feel good as they do nothing to stop the spread.

Said the virus can go straight thru the masks.

Finally found the formula for Oral Rehydration Fluid I was looking for:

This is a slightly edited version of my mask update from the main thread:

My MSA gear just arrived and it all looks good. Everything was new in the box. I did a fit test that seemed to be 100%. I’ll know for sure in a month or two.

I got everything from ebay & it all shipped quickly. The gear listed below seems to be the selection of choice for ARFCOMers that want a quality full face respirator with the cheapest filters at the lowest overall price.

MSA Advantage 4000 series mask # 10083782 (Size Medium - should fit most people unless very small or large head/jawline) - $40 plus shipping

MSA lowrider P100 canisters # 815177 - 120ct for $100 shipped

MSA adapters # 809999 - $10/pair shipped

Also just bought inlet covers to use one filter at a time (conserve filters/rifle use) - MSA bayonet inlet cap # 813341 - $10/pair

If you want to run 40mm canisters you’ll need this MSA p/n 10012413 (spendy at ~ $44) you only need one

Anyone who is interested IM for links if you can’t find anything.

LOL, it’s droplet protection & prevention from touching your face. Though to be any serious help for droplets you need goggles.

Not sure if you knew this, but figured I’d post incase anyone else doesn’t.

Thanks, I use a liquid sea salt solution that’s high in magnesium. I’ll just add a little of each of those to it with some water.

The virus can, but typically the virus suspends itself in much larger molecules of H2O (which the masks DO stop).

Thank you very much for this. Just want to comment on the part in red. I'm no expert, but I believe it's important to adhere pretty close to proven formulas. From the OSR Oley Meeting link someone re-posted above (thank you for that!), there are potential issues with hypernatremia, exacerbation of diarrhea, etc if you go all willy nilly with salts. Not saying that's what you were suggesting, but I'm afraid someone might read that last line & assume the quantities / concentrations were unimportant.

One other note: The ORS formulas I've tasted could DEFINITELY use some flavoring. I've added sugar/salt-free flavoring to my our collection of ORS supplies. Makes them far more palatable.

Question for medical professionals only, please. Or those who have asked this same question to medical professionals & received an unambiguous answer. Or for those who know medical professionals personally & would kindly pass this question on the them :

If you were in a situation where access to medical care / testing was impossible (like if this overloads our medical facilities), had oral (only) antibiotics on hand, and you had a loved one likely infected by NCoV (ill, in the area of a known breakout), at what point would you initiate antibiotic therapy as a prophylaxis against secondary infection? Or would you initiate it at all? I'm thinking the drugs that are normally utilized for CAP (community acquired pneumonia): doxycycline, amoxycillin, etc. This is assuming an otherwise healthy individual.

Just to underscore: I am NOT considering playing doctor unless that's my only option. And I'm not asking for anyone to tell me what to do or give me medical advice - I'm asking what YOU would do, with the full understanding that what you would do as a professional is probably not what I should do as someone who's not one

Hydration is a big deal. I have IVs available to me (medical clinic) but people might want to have an old style enema kit as rectal hydration and nutrition is effective. Slow drip....

Why not just post the links....

Mods, hopefully this is ok, if not, I apologize. Feel free to delete if necessary.

DISCLAIMER: none of these listings are mine & I receive no revenue from sales. I’m not an expert & you should do your own research on correct PPE usage, etc.

BUYING INFO:

To run the cheap P100 filters listed with the Mask below you need one set of adapters. For each mask you buy purchase one set of adapters.

LINKS:

MSA Advantage 4000 Series Full Face Respirator - size medium (he has small & large also - small should fit some kids & small females, LARGE for huge melons/jawlines most average males & females should fit the medium fine - I couldn’t find any specific fit info on MSA’s website) - $40+shipping

This mask uses MSA bayonet Comfo filters so you’ll need this Adapter # 809999 (you’ll need these to use the cheap MSA P100 filters) - $10 for a pair of adapters.

120 MSA P100 Low Rider filters for $100 shipped

If you want to run one filter to conserve filters or use a rifle you’ll need these MSA Inlet Caps - one pair - $10+shipping (one pair will allow you to run two masks with one filter each, no singles I’ve seen)

@BUCK1911

Thanks! Do you know if these work with glasses?

Sure it does...

OVER TIME...

In the 'short term', most of above will last through any pandemic  --that WE survive.

Look on the H-D site for ref to 110 watts, that seems ridiculously low.
