10" Poly Spun white Filter" 1 micron fits our 10" tall clear filter housing Actually 4.75" tall 5 micron recommended for the 1st filter housing ( replaces bubbler ), 1 micron is recommended for the 2nd Dryer/ Spark Arrestor Filter Housing.
( Use a 1 micron, if you have a bubbler tank already) 1 micron easily lets the hydroxy gas pass by and captures any water vapor & electrolyte aerosol gas.) In lab research, the dryer the hydroxy gas is the more combustionable it is. We install a dryer in all installs. We also have a 5" filter for sale. Actually 9.5" tall, can be cut in half to fit a 5" filter perfectly.
