Not that it wouldn't be useful in an emergency but at that price, a simple $2 white nylon strainer bag might be a better choice. Strainer funnels and mesh bags are sold at homebrew stores that are food grade. They work well to filter out solids.

Sewing material stores sell a variety of nylon mesh by the yard that you can cut to fit your application whether for straining liquids or keeping insects off drying food.

Homebrew! It is great for EVERYTHING!
