Disposable Nonwoven Fabric Filter by The Yard 40inch Wide DIY High Efficiency Filtering Made in Korea (White)

This material is being used to make face masks. It is a great to use in between the outer and inner layers of cloth that make up my face masks. I actually make a pocket on the inside of my masks that the polypropylene can be inserted. That way, before I wash my mask, I can take the old polypropylene out and put in a fresh one. This will also work great if you already have a face mask with a filter pocket...say for a PM 2.5 filter. You can add the polypropylene right along with the PM 2.5 for extra protection.It is a good quality, soft and easy to work with. As well, you get plenty of material with this order to last quite a while.

I bought this after doing alot of research online over several months on making your own masks. This is very easy to breathe thru and works great as a third layer, to be inserted into a pocket inside a mask. The only drawback is that you absolutely can NOT iron this stuff. It just melts away. So this is why I use it as a removable layer in a pocket in a mask, in case I want to iron mine after washing it. It is washable, so if you take this out of the pocket, wash it along with the mask in hot soapy water, rinse, iron or dry the mask, then put this back into the filter pocket, you're good. I suspect the price on this has gone up since it being recommended as a third layer in masks, but still, not bad for the price since you can reuse it and there is enough fabric in one order for over 40 filters. Just cut it to fit your mask pocket.

Bought this to add a three ply to my face masks for protection through Covid 19. Works great, lightweight and easy to sew with. No odor or difficulty breathing through the material. Glad I purchased it.

I bought this because it appears to me to be the kind of material the health authorities are recommending to go inside our masks. It's a good size for this. Came on time.
