More surface area for greater dirt holding capacity, Lower initial Pressure Drop, Higher Flow Rate, Washable, Longer Life, Reduce filtration cost.

Removes 99 % of Solid particles from your water source before transferring the water to second stage.

Second Stage

PP Spun 5 Micron Sediment filter 104112

Reduces sediment, dirt, sand, silt, scale& rust particles.

Third Stage

Granular Active Carbon ( GAC) 104113

Reduces chlorine, taste, odors, chemicals,& organic impurities .

This Filter Designed For maximum contact between the water and carbon.



Vertical Hydraulic Gauge

* The first pressure gauge read your feed water pressure (your city water, well or cottage pump water pressure).


* The second gauge read unit internal pressure.


Both gauges indicate you to replace the filters when changes in reading start especially when pressure drop increase, that is an indication that the cartridges are clogging with particular maters or the filters media is exhausted and the water inside the system cant pass through the filters normally.

Excellent Results
The System is working fine - water quality here is known to be poor and the Three Stage Big Blue system takes care of that great. Water tastes sweet and is clear as a bell.

Item is installed and working well. It has definitely improved the quality of the city water and has not affected the water pressure. Unit required some minor adjustments after installation. Customer service was helpful to resolve the issues.
