3M 2091 P100 Particulate Filter, 3 Pairs

Good as per specifications

I have been using the same filters since may 2020 in covid wards. I ordered new filters last week and received it. On opening I could make out the difference between old and new ones. The new ones looks thinner comparatively which makes me loose confidence in using it. Non returnable too. Waste of money for me.

Inerior quality as compaired to filter catridge comes with M respirator, in fact one of the cartrige grooves to fit with respirator were missing. Since I opened second pair of filters after 2 months of purchase so can't even claim for replacement

Sin ningún problema, los use para lijar madera Parota y ningún detalle. Excelente era lo qye esperaba

Having spare respirator filters on hand is non-negotiable for me, so this was a nice way to pick up quality, name brand replacements for a fair price. Will buy again.

Pack of three pairs of oem dust filters. Fit my 3M half face respirators. I wear these for hours a day woodworking and you can definitely tell they work since I’ll cough if I don’t wear them

Dudo que sean originales pero estoy en un50/50 ya que para lo prometido no me funcionó y los olores traspasan aún estando nuevo preferí usar el filtro 6001 que me funcionó más en la mascarilla que uso ya que ese no permitió traspasar el olor pero los 2091 si traspasa el olor

I've been using these for years and this particular pack is worth it for the value. Filters particulates well, though not perfectly with the mask I have.
