Does anyone know anything about cartridge respirators, such as which cartridges protect from what ??

I would like to protect myself from stick welding fumes and painting fumes.

Also, I have an abundance of galvanized steel; is there a cartridge that would protect from welding that ??

I found some that say North brand, 7583P100, organic vapors.

Is this what I want ??

Please advise.

What do you guys do to protect yourselves from welding fumes ??

Thanks.:)

North and 3M are popular makes.Organic vapour is not the right one for welding. The manufactures have charts showing which filter P100 is a common filter. I would get either North or 3m as they are most common.Am working alot with stainless steel and we use air supplied breathing gear.A good respirator and the RIGHT cartridge works quite well for most welding applications, a different catridge is used for paint and that depends on each type of paint.Not cheap but worth every penny.

This is what I use for welding. It fits under the hood and works well.

3M? Respirator Assemblies 6000 Series


They have different sizes, S,M,L,XL; how do I know which size to get ??

I am six-foot, 210#, with what I hope is a normal-sized head.:confused:

I am also considering this one :

Amazon.com: 3M #7503 Large Half Mask Facepiece: Home Improvement

How do you think it will work with a standard hood ??

I think maybe #2091 filters as that is what comes up first when specifically looking for ones for welding.

Which filters do you use ??

This one looks like what you linked to, right ?? :

Amazon.com: 3M 6391/07003 P100 Reusable Respirator Gas Mask, Large: Home Improvement

Sorry for so many questions, but I have never in my life had a respirator on my head.:rolleyes:

Go to a safety equipment supplier store. Respirators should be fitted and tested by a professional, poor fit = no protection.

Same professional will pick the right can for your uses, sometimes the need a dust pad added to the exterior some need two cans stacked together.

Using the wrong can is the same as using none!

OSHA has standards for respiratory protection that incudes baseline testing of pulmonary function and health monitoring, you can't get this correct on-line or by ordering from a catalogue.

Yep, the second one is what I use. it's probably best to follow Wis Bang's advice.

Once the charcoal respirator is opened and exposed to the air, they have a life expectancy. I forget the actual amount of time but I think it was around 2 days. Maybe a week. Read the label.
While you may use the respirator for weeks, it is only effective for a short time. I painted semis with polyurethane paint for years with a charcoal respirator. In the end, before I got out of that line of work, I used a fresh air pump/respirator. Wish I had it back in the 70's and 80's. Too late now.

Listen to Wis Bang.

Go to a local supplier, like Granger or another industrial/safety place. Fit is extremely important and 3M at least has a ton of different cartridges depending on what your facing, and if theres oil mist present. Oil mist can destroy a cartridge not approved for it leaving you unprotected.

3m has a large poster describing what model filters are compatible with what chemical.

After a charcoal cartridge is open its only good for a short time as mentioned, like 2 days. Its best to store cartridges in a air tight package to preserve them.

The pancake P100 filter pictured is what i usually wear welding. They fit fine under a welding helmet.

Go to a local supplier,


I hear----well actually read that so often.

In this bottom-of-the-bucket isolated third-world little place where I live, it is over a hundred miles to anything even close to what most take for granted every day; that is why I seek education, information, and advice on these forums.

I figure what works for others should work for me.


Thanks for all the information so far and please keep it coming.


Does anyone know if that 2091 P100 filter works for welding galvanized ??

If not, then what does ??


I don't often weld galvanized and avoid it whenever possible.


Thanks everyone for the help and advice.:)

On edit:

I just found this :

Read page two, the section about use when welding.

If I understand correctly, service life is not so critical for welding particulate filters, so long as "oily atmosphere whatevers" are not present; the more crud that collects/cakes on the filter, the more efficient it becomes, until you finally smother to death from it becoming completely clogged.

P100 is approved for "metal vapours". Its is also "P"ermissible to be exposed to oil. Bear in mind that you can oversaturate the filters ability to clean the air if your into heavy galvanized and are close to your work. Most pro welders who weld galv wear powered respirators. THe filters typically are on the back so they are out of the heaviest concentration of fumes and dust.

Service life is a little hard to quantify, while it doesnt have charcoal that continuously is "filtering" even when not being used, it will clog as you breathe. But that will depend on use and environment. You can see the pink filter turn to black. Use your discretion as to when to change.

Dont underestimate the importance of proper fit. Better "softer" (ie:more expensive) masks tend to be more forgiving on fit. Its one of those things thats hard to buy over the internet. Is there no agriculture or even autobody supply near by?
