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 filters 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 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.

- No odor
- So I originally bought some no-name brand 4x12” filter on Amazon, and it didn’t work. I replaced the shitty filter with a 4x12” Phat filter, and now the odor is GONE! I wish I got this filter from the start.
- 4x12 Phat Filter
- I just hung it up, haven,t used yet, but what I have been told and read, this is called the best filter out there. I sure hope so..lol
