Reusable 2.5PM Face Mask Filters (10-Pack) | $9 | SideDeal
If you have a face mask with filters, you’ll probably need to replace them at some point. At MorningSave, a pack of 10 reusable and replaceable filters costs just $9. These 5-layer filters protect up to 2.5PM (fine particulate matter) with activated carbon, which is supposed to be more effective at absorbing toxic airborne gases. You can wash and reuse the filters after a couple of wears, too, but don’t go too long without replacing them altogether. Order your pack at SideDeal if you’re running low.
