ZANFUN 20pc Replacement Filter with 8pc Exhaust Valves Set DIY Non-Woven Filter Accessories Set for Outdoor Sport

Rough plasticy edges... cut up the top of my nose. Found that using k-tape to cover bridgekeeps the rubbing from happening. Won't buy this brand again.

These aren’t the same liners as the one that I received with my WISREMT mesh mask I purchased previously, definitely different manufacturers. However, I don’t like the additional vents that come with these replacement filters, my masks original vents were much more compatible to the mask. These vents are larger, but I can breathe with them. Overall, I like having the liners and being able to change them out. So I would say these were a good buy.

I loved them. Feeling safe out here in these streets

Good product, the wait time to get them is rediculas and very slow! Takes months to get the product. Terrable customer service.

Funny they don't fit the mass that they were purchased with or for the holes are too small for your for your one way valves if you get a pair of scissors and trim off just a little bit but not too much otherwise it's worthless just think everyone should be aware of this before you spend your money and depend on this to protect you from covet the Chinese disease

Great product, easy to hand wash and clean. They do survive well as long as you're easy on them. Fits in The mask well. Made in China and takes a long time to deliver

I still have these, I am tall so my face large, I must split them slightly to be comfortable, I bought these as COVID broke out, even though I got them to keep my lungs cleaner while airbrushing. I wore my mask out in public and lost the cloth housing. Grr, I will now go order another fancy face mask to hold these.

The mask for these filters works well. First one I have used that let me breathe. Used for six hours straight and got liner dirty and sweaty. Just swapped the liner for a new one, nice not having to wash the whole thing
