Activated Carbon PM2.5 Filter Insert - Protective Parts Replacement for Air Breathing

THESE DO NOT FIT RZ masks. ITS ANOTHER AMAZON SEARCH MATCH deception.

They dont fit the traditional N99 masks. They ate not cut correctly. Dont waste your money

These look like perfectly good filters, they do NOT fit RZ masks as some have said. Do not buy for your RZ mask.

Not even close to fitting RZ masks

These are not comfortable and conforming like the originals. They are like wearing a scratchy cardboard kids toy and most importantly they DO NOT SEAL PROPERLY due to how stiff the material is.F-

Great value for your money

Wholes are not big enough for valve ports/mask

Seemed to work fine I'm the only thing is it arrived a little bit late later than expected
