Each Original Can-Filter uses our thickest granular-carbon packed-bed design to deliver the best performing Can-Filter on the market. Even with the industry’s thickest 2.5 in carbon bed, the Can Original maintains minimal pressure drops. This hefty granular carbon bed effectively makes the Can Original a massive sponge, soaking up VOCs and capable of holding massive amounts of contaminant. The Original Can-Filter® is designed for the control of VOCs (paint fumes, hydrocarbons, etc.), odors, and other gaseous contaminants. Rated at a conservative 0.1 sec contact time, the Original Can-Filter® provides excellent value and confidence.
