The organic vapor cartridges filter out VOCs from paints, stains, solvents, etc. and the white N95 pre-filter pads do a good job extending the life of the cartridges and filtering out airborne nastiness. The straps do a good job keeping the mask in place and the price is good. Definitely something good to have on hand.To clean, I'd recommend unscrewing the cartridges and wiping it down with 70 ethyl alcohol using a clean rag before letting it air dry. I'd also recommend purchasing and extra pair of organic vapor filtering cartridges and N95 pre-filter pads if possible. I don't know how long the organic vapor filtering cartridges are supposed to last, but I've gone a couple of months of regular use without issue.
