20'' Big Blue Carbon Sediment Combo Filter

There are many applications where there is only one 20" Big Blue housing installed. Carbon blocks have the most carbon capacity, but very little dirt loading capability.  Sediment filters have a high capacity for suspended solids but no carbon filtration.

Here is the solution to this dilemma, a filter that combines high dirt holding capability of a sediment filter with carbon to treat taste, odor, color, chlorine and DBP's.  Our MMB filter has a tremendous surface area of carbon, this type of filter construction allows the filter to hold a lot of dirt while maximizing carbon contact.  In tests this type of filter tends to outperform a carbon block when new because of the vast surface area of carbon but organic removal performance will fall off sooner than a carbon block because there is less overall carbon.

Some choose to run this filter even in our triple big blue setup and change this filter every 2-3 months to extend the life of the carbon block filters in the second and third position.
