Great idea! And the following information is from the CDC, found on
https://www.healthline.com/health/best-face-mask-2#materials

The CDC suggests using two layers of tightly woven 100 percent cotton
fabric — such as quilter’s material or bedsheets with a high thread count —
folded in multiple layers.

Thicker, high-grade cotton masks are usually better at filtering small
particles. However, stay away from materials that are too thick, such as
vacuum cleaner bags.

In general, a bit of breathing resistance is expected when wearing a mask.
Materials that don’t let any air through can make it hard to breathe. This
can place pressure on your heart and lungs.

Built-in filters

boost the effectiveness of DIY face masks. Coffee filters, paper towels,
and just about any other filter can help boost protection.
