Question about a sari filter...

[MustangGal]

does the "sari" actually need to be an indian cotton sari or would any type of folded cotton work? I thought an UNUSED indian cotton prefold diaper might be an even better (and cheaper) option.

Does the weave matter? The number of layers? The ease of cleaning, since you can unfold a sari?

Thanks!

I'm gonna go out on a limb and say it needs to be the tightest weave possible but I don't know much about this.

Looks like a good time for you to show some pics/movie so i can learn something:) !

Sounds like what we used to accomplish by placing a coffee filter over a canteen cup with a rubber band and pouring water through.

Course this is JUST a rough "debris" type filter, you would still need to properly filter it and/or chemical treat it.

Right, but it would make your regular filter last longer, wouldn't it?

remember that all pathogens are not blocked by this filter...

HEPA filters filter down to .3 micron, and the smallest of bacteria is .2 micron (ya thats pretty darn small), so if you are using "questionable" water, it is always best to filter (reverse osmosis is best-but wastes alot of water) if you use anything less than a HEPA certified filter on said questionable water, its best to also either chemically treat it (iodine or chlorine) or bring it to a rolling boil...

Hope this helps you out MustangGal.

In theory yes, still need a real filter.
