sorry for the missunderstanding. i didn't mean to " brand bash" saying that 3M was better than any other brand.
but those replaceable cartrige masks get slimy and gross from use. i'de rather have a new mask then and old dirty one w/new filters on it.
some of those charcoal filters come in a 6-10 pack and most people just take one out, and leave the pack laying arround. the charcoal will continue to filter out the air you store them in. so in a month or so when you need a new cartrige, your replacements that were sitting arround are allready junk.
those 3m ones are good for 40 hrs. or 30 days{wich ever comes first} of constant use.
and pasngas,,,,
you put new media filters on your mask,,, how about the charcoal canisters underneath? those need to be changed as well.
