I bought this new in 2018 and while I find it better than a half mask respirator, I am disappointed that somehow it still allows some aggrivating fine particles in. I wish I had a way to test it's effeciency. I have inspected it and the filters and noticed there are some very small flaws on the plastic molded sealing surface in the blower unit. I don't know if this accounts for the problem though since the filter has good pliable seals on the outer edge and around the intake for the impeller. If you have a high sensitivity to sawdust this may not be the ideal solution for you.
