DIY Smoke Extractor! Simple Homemade "5-layer" Water-Based mini air cleaner. this purifying air filter uses water to clean the air of smoke, fumes or odor from cigarettes to solder fumes! works by pulling air thru several layers of loose knit absorbent "water saturated" pad (evap. pad). clean air is then sent back into the room via a small dc fan. this "water based" design removes nearly all odor from cigs to solder fumes! to make: only 3 items are needed: a plastic container, a small 12VDC fan and a few scraps of evap. cooling pad. that's it. can be run on battery, solar panel or wall current. video shows tests using incense (sticks and cones) along with solder and soldering iron. works great!. note: the pads will absorb nearly all the smoke, fumes and odors along with all the associated "particulates" - so they need regular cleaning. to do that just hand wash them in hot soapy water and rinse them out and you're good to go.
