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.
