QiYue 100 PM 2.5 Activated Carbon Filters 5 Layers for Mask Neck Gaiter with Pocket Insert 5 Layers Replacement for Women Men

Estan fabulozos y lo mejor es que son reusables, y por su precio, ni que decir, es una ganga total.

Something in this filters is incredibly irritating to breathe through0, plus are difficult to breathe thru. It caused a mild allergic reaction after a few minute use! My lungs felt itchy, my nose and mouth were itchy. These are terrible! I opened up thr filter and the "filter" materials inside seem to be powdery. Yikes! I threw them out and purchased a HVAC filter from the hardware store usually used for my heater/ac. I tore apart the frame & cut down the filter to dozens of filters for masks. Massively better! Easier to breathe by a million miles and no gross weird mysterious filter material going into my lungs!

These are packed to perfection. They are great quality and fit perfectly in my homemade sewn masks. They come 10 per individual pack... love that!

These work great for adding an additional protective layer to my masks. They are not so thick that it is hard to breathe through and the way it was packaged in counts of 10 is wonderful. They are super easy to slide into a mask pocket and they are pretty durable for what they are.

good

Pleasantly surprised! I saw these were somewhat individually wrapped. I love that! They are wrapped in bundles of 10. I can just put a package of filters in my purse. Shipping was prompt. Recommend

These are great for our face mask that are needed to help spread the virus.

These work and fit perfectly in my cloth mask for extra protection
