i just bought a new double cartridge resperator (3m)from el cheapo(whatever the only double cartrige resperator they sold..i forget the model name) .and im wondering if any one knows when the filters stop working????????????????i remember being at a meeting with a 3m rep representative years back and i forget how he said u can tell its not working anymore

I have the same resperator, You will know when the time comes for when they need changed. I change mine when they don't seem to be working any longer. Guess it also depends on the style you have. http://www.coopersafety.com/brand/1...rators&ag=3M&gclid=CPujvODT1pECFQUQlwodsyLwag

how many days or hours do u think they last ...................ballpark guess just for the hell of it

 

[slickshift]

They have more than one model
They will last differently depending on how they are used
They are also date stamped on the package

i know that and i wrap it in plastic and everything i just was wondering when i would expect to need new cartridges..i know its a hard question to answer

 

[slickshift]

Hmmm...not sure I've heard of an "hours used-replacement" guideline or anything...

Depends on what we have going on. Using for paint fumes, they will last long. Using for drywall sanding or demo, they may last only one job.Trust me, you will know due to the change of the way the filter is working.

Generally when they are visibly clogged by dust or dried spray mist. Or, when you are wearing it and you no longer feel like you are comfortably breathing filtered air, when you inhale you feel that the inside of the mask is sucking in.

Hard to put a timeframe on it...depends what its been exposed to and how much. Generally, no longer than 3 months for us. Keeping it clean and in a sealed ziploc helps. Also, carry spare cartridges.

i bought a new one last week and ever since ive been priming almost all day everyday with cover stain and bin...so i guess its still in pretty good shape i just posted this because i was worried i was not gonna be able to tell and i would hate to wear the resperator and think its working when its not(it is uncomforatable to me the bridge of my nose is sore as can be from it) but now i better understand what to look for thanks.

With BIN its real easy. When the inside of the mask starts to suck in it breaks the seal to your face and you will smell the BIN for sure.

(it is uncomforatable to me the bridge of my nose is sore as can be from it) .

Your face just needs to adjust to something new. Wear if enough and you'll forget it's there.

yea ur right i will adapt....thats me being a little bit of a puss*

:detective: your nose might be sore because you dont have the right sized respirator for the size and shape of your face.these things come in different sizes and you should be fit tested for the proper fit the first time so u know what size u will need afterwards.also if u gain or lose weight you will need a different size respirater because your face size changes.u change filters as often as needed,no set time frame. could be 1 hour depends on what u are doing.for dusty environments use pre filters to pro long charcoal filter life or remove charcoal filters and use hepa filters (round pink ones)or stack hepa's on the charcoal i use all these combo's.:thumbsup:

That is my experience. I just finished with a lacquer job (all notty pine wrapped windows, trim and doors (33) ) on a 4000 sqft home. I had to change the filter twice in the same day. Lacquer gets foggy and clogs it up fast. Soon the mask was hard to breath through and I began to get a faint smell of lacquer. I don't really use a respirator like that for anything other than lacquer/thinner product in confined spaces. I could only imagine that a respirator in a latex environment would last 10-20x's longer? dunno...

Experience is the best answer. And your allready on that path. :thumbsup:
