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 'œrounded-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 'œd') is the key. It tells you how good the carbon is. So how do you find the Adsorption Yield? It'™s an easy equation: 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 filter is of higher quality and will sustain a longer life-span. This is critical when choosing a quality carbon filter like a Phat Filter. So compare the numbers and you'™ll see for yourself that Phat Filters are easily the best deal in the marketplace today! Phat Filters numbers don'™t lie. For more information about Phat Filters visit www.phatfilter.com
