Phat Filter 24" x 8", 600 CFM
Phat Filters are packed full with the very best carbon on the market… and we have the independent lab test numbers to prove it. How do we know? Simple math. Carbon Quantity x Carbon Quality = Filter Capacity QUANTITY: When we say Phat Filter carbon beds are 2" thick, they are in fact, 2" thick. The same is true when it comes to Phat Filter bed length size; the size we claim is in fact the actual size, not a “rounded up” dimension to make it seem bigger. So it stands to reason that we can obviously pack more carbon into our fi lters than some others can claim. QUALITY: Phat Filter’s quality is also backed up by math and science too. ADsorption Yield (adsorption with a “d”) is the key. It tells you how good the carbon is. So how do you fi nd the Adsorption Yield? It’s an easyequation: Dry Apparent Density x Butane Number = Adsorption yield A high adsorption yield number equals a greater capacity to adsorb odors, which in turn means the fi lter is of higher quality and will sustain a longer life-span. This is critical when choosing a quality carbonfi lter like a Phat Filter.
