[Free add on with purchase] BNWOT Bundle of mask filters, PM 2.5 by Weddingstar

New and unused bundle of mask filters, PM 2.5 by Weddingstar. I think there may be 18 filters left, each individually wrapped so no chance of contamination. PM 2.5 filter inserts are said to provide excellent protection against small airborne particulates. PLUS 5 brand new and unused flexible plastic under-mask inserts that allow you to breathe better when wearing a mask. This insert keeps the mask off your face which helps with breathing, helps to prevent acne caused by cloth marks, and minimizes the aspiration moisture on the mask.
