Mask Filters - PM2.5 - Custom Cut for Origami Face Masks

Pack Of:

These PM2.5 mask filters are custom cut and sewn to a slightly smaller size than the average PM2.5 in order to fit all PlatterCats origami masks.

These are generic, five layer, activated carbon, PM2.5 filters that you can find online with the bottom edge cut and resewn to the height of PlatterCats origami mask pockets.

Two sizes are available (adult and kid). If no size is selected on the main page, then the adult size, or the size of the mask/s ordered, will be provided.  

All filters are UV-C sanitized before shipment

        Please keep in mind that the number of days to receive your order once it's in USPS's hands is an estimate, not an official number. 

        Most packages are showing up on time, but a number of them have also been showing up 7-14 days after the estimated timeline.  Please be patient with USPS as they're doing the best they can.

        These shipping delays are unfortunately out of our hands once your package is dropped off at the post office, but please feel free to reach out if your order looks to be extremely delayed by USPS, or if you have any questions or concerns.
