Phat Filter 4x12 Carbon Filter

 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.
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.
