Works great

Great for the prize. I live it.

These r better than the cheap stuff that we get locally

We began using these in place of N95 during the Covid 19 era after N95 became unavailable at the auto supply or big box hardware. Whether true or not, believe better than just cloth without this filter insert and are easier breathing than standard N95.

Worked great for me

This is the perfect size for home sewn or commercial masks with area for protective pad to be inserted.

Un producto de excelente calidad y las entregas puntuales

It fits nicely into cloth masks.

The mask filters very much help with moisture that always seem to be present when I am wearing a mask, which, thanks to the pandemic is still required when I work. I am so happy with the filters which absorb the moisture under my mask.

It could be a little larger as it does not fully cover both nose and mouth of an adult, as others have mentioned. Otherwise, easy to insert, no visible problems with product, no odors. Just remove and throw away before washing the mask.

Price was right for a mask filter.

These filters work well Sith the masks I own. They are also comfortable.

They fit all our masks, including kids masks, don't smell, and seem to work. So nice to be able add extra protection to our most comfortable cloth masks.

So far so good. My throat is usually sore after wearing my mask for very long. Don't know if this has to do with the filter or not?

I like that I got so many in a pack for the money.

Quality is excellent. Products are very well made.

ok

Works! Good price.

Great filters to have especially with masks with a pouch sewn in.

Great product for use with masks that provide a pocket for a filter. Understand that breathing takes a little more work when you add a filter of any kind. We feel very protected using these filters in a variety of masks we have.
