Review on KISCHERS Cartridges Respirator，Replaceable Filters Accessories by Eddie Duncan

They fit my 3M 7503 half mask snugly and work great. I've only used them for some woodwork and a little painting, but I've been using respirators in my workshop for many years so I'm sure they will continue to perform well. This is a carbon cartridge (for ink vapor). etc.) with a "normal" filter as a pre-filter to filter out fine dust. I couldn't find a quality rating for these filters on the packaging, but the filters' model name includes N95, so I think that's their rating. It comes with 4 activated carbon filters and several particulate filters. Unless you're used to activated carbon filters, they're a bit heavier than regular dust filters, but you won't notice this unless you whip yourself out. head from side to side. In terms of difficulty breathing or inhaling, I haven't noticed any difference between these and other filters I've used in the past - I've had no problems. They work well, fit great and I always recommend a respirator. with interchangeable filters for those who work with wood a lot - it's much better than the paper masks with rubber bands some people use. Spend a few dollars and buy a quality respirator and lung protection filters.
