And set up for 5 gallon buckets.

8 bags for $43 doesnt seem bad. QUOTE

What do you guys think? I had no idea they were for anything nefarious. .

Interesting idea but for pre filtering drinking water I suspect it's a sketchy product. A first clue is the colored (dyed) cloth. There's no mention of the type of material, of it being made of food grade material, or of it being safe for pre filtering water. 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.
