New 3D Cutting Five Layers Activated Carbon Filter Replaceable Anti Haze Filter Paper Larger Protection Area 50 PCS(Ship from USA)

as an essential worker, i have had to look around and find a max and filter that fit well together and was comfortable enough for a man with a long beard. these filters fit perfectly inside my mask. from the bridge of my nose to the bottom of my mouth are covered buy these filters. Thank you so much

Check how your mask is sown before buying. It's my fault for not verifying first but even though my mask has the shape of the filter, the mask is sown in a way where the shape of the filter doesn't fit. I'm disappointed in myself. I guess I'm in the market now for a face mask that fits these filters.

Ordered this on Sept 26, expected by Oct 13, shipped from US. Tracking showed however it shipped from China. Tracking stopped on Oct 13 and Amazon said it was likely lost. I contacted Besta Store-US for a refund but they said I might still get it and to wait. Sure enough the masks showed up Oct 26. After all that, although they are well made, they are too big for most of my masks!

I am so happy the filters arrived before schedule ! they look great and exactly as described, I am very happy with the product.

Bought these for my husband's masks. Previously using the 4x3 filter insert that just covered his mouth. With the 3D design, he said his nose is covered and he felt he was breathing better. Definitely recommend and will order again.

Plan to use for cloth mask inserts. Good thickness and general sizing.

These are great inside of fabric masks- I feel safer knowing the filtering covers a much larger area than the smaller rectangle ones we’ve been using for months. The 3-D shape isn’t overly dramatic, and actually just enough shaping to help keep the mask a little bit away from your face which is helpful. If you’d like more complete coverage as the pandemic rages- these will provide more peace of mind for sure !

These inserts seems to be of good quality and they are nice and wide coverage area.Reason for 4 stars is they are too large to fit in several masks that are made for adding inserts inside the mask. Bought as a gift and this was the result was told.
