Homemade "Straw Style" Water Filter!. Easy DIY. This Straw Style Water Filter is small, lightweight and powerful. good to have when hiking/camping and ideal for in a SHTF/Emergency situation. is 99.9% effective at removing many common disease/cancer causing water contaminants. also is excellent for purifying rain (or tap) water. full step-by-step instructions. items needed: poultry baster, coffee filters, cotton balls (optional) and activated carbon. *all items found at dollar store - except the activated carbon ($6.00 at walmart). also sold at most aquarium supply stores. filter should last for years with regular maintenance. the activated carbon is rated to last 5 1/2 months (24 weeks) if used continuously. change cotton/coffee filters as needed.

1.) one turkey/poultry baster (to make the "straw"). cost $1.00

2.) activated carbon (from walmart, most aquarium supply stores or amazon). $6.00 for large jug of it

3.) paper coffee filters ($1.00)

4.) cotton balls ($1.00)

5.) rubber band, string or twist tie (free)

push it down into the tip (end) of baster (see pics above)

new activated carbon has a very fine residue on it. for it to work properly you need to rinse it first. be patient because that can take a few minutes (see pics above). after rinsing, clean the sink!

cut down coffee filter and make a cap for the end. attach it with a rubber band, string or a twist tie

effectively filters tap-water, rain-water, river-water. This type of filter works best to purify tap water, rain water and river-water. the filter eliminates any bad taste/odor and restores clarity to water. it also removes silt, debris, sediment along with over 200 chemical contaminants (including herbicides/pesticides, pharmaceuticals and on and on). note that if you are filtering lake/pond water (or any other stagnant body of water that may contain pathogens) you should pour water thru filter and into a collection container and boil it before drinking. boiling can be done before or after you pour water thru the filter. note: nothing grows in fast moving river water so that does not need to be boiled.

cut the top off of the bulb part of the baster and connect it. then just pour water in and hold over a container (to collect the filtered water).
