does anyone know of any designs on the net for a diy carbon filter. I'm going to look around i was just wondering if anyone had any really good ones they's like to share. I have a copy of this heads edition ghetto tech carbon filter but the instruction seem a little confusing.
Most all can carbon filters use the top 50% of the carbon in the filtering process so the Pro filter is my choice as reversable thus giving you twice the time it remains effective. http://www.nationalgardenwholesale.com/acro_cat/AirPurf_p133-137.pdf
