Activated Carbon Filter Replacement Parts Reusable Filter Refill for Cycling Dust Woodworking Mask

they do their work, but they are 1/5 of thickness of the original ones (N95)

These are filters for certain types of masks.. these are not masks themselves.

I was supposed to get replacement filters for an existing mask. What I actually got were KN95 masks with breather valves. The quality seems pretty good, so I’ll use them. I’m giving the masks 4 stars for quality and 2 stars for being the first incorrect item, so 3 stars overall.

Order this as a combo as suggested, only got 1/3 of my order. This sucks.

I really found the quality was terrible. Did not fit the mask. Cheap Chinese junk. I went to a physical store instead to buy a proper mask and filter. Online is not always the best.

It was very uncomfortable to wear, so had to change to a different set of mask. Keeping it as back up.

Shipping took almost a month. Then when they FINALLY arrived, they don’t fit in the RZ mask. As a medic in a very busy city, I needed these filters to fit.
