I have used a versa flow m300 and m400 with gvp-1 blower for literally thousands of hours. They are worth the weight, bulk and annoyance for the protection they provide. The m400 neck cape is a way better system for someone with a beard. Be sure to follow the manual and replace your filter often.

If the substance is organic like rust or dirt is, it's not going to hurt your lungs.

Rust and some dirt is NOT organic.

Wood is. I had a good friend die a few hours after cutting redwood due to a developed allergy, and know multiple people that eventually changed careers for the same reason.
Concrete dust is supposed to be safe

Absolutely not. Look up silicosis

Rust is organic. It's plant matter. Little plants growing on the steel.

Nope.

Your posts in this thread are some of the most misinformed I've seen here in a long time. Please stop and do some research.

A good rule of thumb is : if it makes you cough, it's not good to breathe.

Caustic cleaners or acids used in a spray bottle will make you cough and will require a respirator.

Polyurethane paint will require a respirator for sure.

The kind of dust that plasterers are around are very bad to breathe.

Concrete dust is supposed to be safe but I don't think so.
This is one of the dumber things I have read.

Organics don't hurt your lungs and concrete dust is safe? Holy ****

I hope no one believes any of this garbage

Hopefully you are not in a position to influence others that are also ignorant of the facts.
Tell this to the miners that got black lung or the concrete workers who got silicosis

I can see using a supplied air hood for something like body filler dust, but for metal? Even if it's rusty metal, the stuff isn't that bad really.
If we're talking mild steel, I'd partly be in agreement. Iron and iron oxide themselves are fairly safe in many forms, though any particulate matter in the nano-particle size is known to be dangerous because of it's ability to pass directly into the bloodstream. This includes stuff like aluminum oxide (your abrasive) and even stuff as innocuous as zinc oxide dust.

However, not all alloys are created equal. Railroad workers who took such a relaxed attitude while grinding on switches (frogs in particular) have a very high rate of parkinsons due to the manganese in the metal dust they inhaled. And we're talking about a very minor alloying metal causing all that trouble (workers who just grind rail did NOT have the same issues).

Also, abrasive cutting of metal (except when using something like diamond) leads to more abrasive in the air than metal dust. Cutoff wheels spew loads of fiberglass, binder (that's the burning smell) and abrasive, much of which reaches the into nano-particle size range. Some of that gets absorbed by the body, but anything that cannot get dissolved gets encapsulated, and that leads to things like silicosis, black lung, and all of the asbestos related disorders.

any feedback on the small belt worn electric units?
I agree on the 3M mask

Got an example?

I used them years ago, great for an industrial environment as there's minimal training and no medical needed.

Filters can get pricey
I've had good luck with *zon dot com PAPRs and 3M OV100 filters. not working with anything super dangerous, but continuous airflow is real nice vs a stuffy face.

There are plenty of wood dusts that can cause Nasopharyngeal cancer.

That's what the carbon stage of the filter is for.
Yeah you can tell how effective that is by how many jump up tossing off their hoods & masks and furiously look around for who did it.

I don't work on the weld line, but I can see them from the departments I do work in, and it happens enough you don't have to be close by to know exactly what happened.

LMAO. I sleep with a CPAP, and yeah, I can easily tell whether or not I'm facing towards or away from it...

so I bought a couple things to put together a system.
AirBoss Defense hood and pump.
Uses 40MM screw on filters(called NATO filters)
2 different types,particulate and Vapor.
Much cheaper than the OPTREL or 3M filters.
This unit uses 3 of the vapor canisters or 2 of the particulate ones.
I bought a new OPTREL grinding helmet and will connect the AirBoss
hose to it.My total cost including shipping was $200 for both.
I think the AirBoss hood will work also and will accommodate a beard down to belly button.

If you look on ebay you can find open box OPTREL units for around $400.
Again think of the consumables cost....$60 each for filters for that brand
or the made in USA 40MM ones on sale on ebay for about $8 each shipped

Who is making the filters that you are using? Can you share a link?

A 100 pack for that price makes me very skeptical of their claim to be made in usa. Maybe they assemble the filters here, but I doubt the media is us sourced

I work in that industry
Buying safety gear like this on eBay wouldn't give me a warm and fuzzy anyway...

Typically if I'm wearing a respirator or such I REALLY do not want to breath in whatever I'm dealing with...

I suspect this is all surplus coming off a high from government assistance programs due to covid.

Possible, but the assistance we got was with equipment, not materials. Maybe it was different for them

That kind of media doesn't really have a shelf life if it is kept dry and clean, so sitting in a warehouse shouldn't be a problem, afaik

Just key those words in ebay. several for sale
I offered $85 plus shipping and they took it.
Thanks! This site's costing me money again, but I've been daydreaming about a PAPR for quite a few years now. $86.20 shipped with tax included. https://www.ebay.com/itm/236236883418
They must have had a huge overrun.

When it comes in, I'll decide if I'm in for a 100 pack of filters...

What are you guys using these for?

Last time I wore one of those yellow hoods it didn't seem really designed/comfortable/safe for "garage" work. Pretty sure sparks will burn through it instantly

Agreed. That looks like it was made as a quick, better-than-nothing fix for the pandemic. Not for a workshop

I got the hood for my bearded son to wear while spraying with our industrial grade pulse jet fogger.
The OPTREL helmet will be used for everything else,grinding,painting etc

I don't really do anything that makes sparks that also calls for a respirator. I stopped using glued abrasive wheels for the most part, and diamond ferrous cutting grinding wheels throw down a coarse dust that a KF-94 mask under my full face shield easily handles.

Sanding (and to only a slightly lesser degree, cutting) wood creates a dust that lingers in the air to the point that I'm not happy with negative pressure respirators, both in that you're always sucking in a little contamination every time you move, and there's also that sweaty mask face. I have a home made dust collect pulling from the bottom of my cabinet saw (I plan to add an overarm shop-vac connection one day), and a shop vac dedicated to my sliding compound miter saw, and in good weather when I can roll up the garage door and turn on the fan it's almost like I'm working outside. But in the winter I start to remember what it's like to work indoors.

Then there's my sandblaster. Its dust collector works to keep a negative pressure in the box, but I get a haze around the area while using it that concerns me. I don't blast with anything containing silica, but that sort of haze makes me pull out my P100, and wearing a P100 just plain *****.

There's applying pesticides. Everything I do can be made safe with an N95 (or less; I don't work with anything actually dangerous to mammals), but N95s come with sweaty mask face, and working outdoors in Long Island humidity you can cut with a knife...

And then there's smelly jobs. About a decade ago, I brought someone to the ER in a delirious code brown situation. The very kind ER nurse gave me a disposable surgical mask with a carbon lining that really helped (since it's an issue they deal with every day). I took that to heart and bought a few hundred a little after that, and used them working around the cat litter, cleaning drains, etc.

The eBay pictures make me think the included hood I just bought is made of tyvek and is disposable. But I don't see why I couldn't connect the hose to a better hood. Or make or modify something to my needs as they arise. I've got sewing machines, kevlar thread and plenty of leather. Anyway, I bought it for the blower, and as ******* pointed out, the affordable filter system.

Im embarrassed,you found one cheaper. I ll follow that lead and buy one for spare parts
With high volume surplus like this on eBay, you never know what the cheapest item will be, and I think I just got lucky (though I did spend some time searching). The market looks pretty saturated, so anyone looking to move product will try to undercut the next guy. I'll expect there's a lot of "smarter" guys holding back their listings until the lowest priced ones sell out, so it may be years before this inventory fades away.

I will say that the cheap plastic belt needs to go.
Im visiting the local pick and pull to get some seat belt material
to replace the plastic. The same fasteners can be reused
