Gas mask pad filter reusable

This is a reusable gas mask filter. If you do not want to cry when cutting onions, this might be your solution.

The size is for standard makeup removal round cotton pads. To make it even more effective, you can cutout round filter pads from activated charcoal. I had some laying around for the air filter in my kitchen. Worked like a charm. Filtered out the onion smell completly.

No supports needed.
