Whole House 10X54" Carbon Whole House Filter. 1.5 cu ft. Upflow Valve
As you might guess from the name, upflow systems basically function as a downflow filter in reverse. Instead of water flowing down through the filter media from the top of the tank, water travels down the distributor tube and flows back up through the filter media – carbon, in this case – and out of the tank.
Up-flow systems direct the water in the up-flow direction of the system. The water comes into the water system tank and flows through an upper basket and then down a riser tube in the middle of the tank. Once the water reaches the bottom of the riser tube it is then distributed through a lower basket attached to the riser tube. The water then flows from the bottom of the tank through the filter media in a swirling motion. The swirling motion is created by the reaction of the water coming out of the lower basket coming in contact with the bottom of the filter tank which is rounded or curved. An up-flow design eliminates the need for backwashing on most filters because the filter media is continuously being fluffed each time the water flows through the tank. Another advantage to an up-flow design is the amount of contact time the untreated water has with the filter media. An up-flow design also forces the filter media to swirl which in turn allows the media to have longer contact time with the water yielding better results
Upflow filters are better suited to filtering city water than well water, as they are not equipped to handle sediment, rust, and odors like a downflow backwash filter. If you have sediment in your water, please add a sediment filter to your system. Because upflow carbon filters don’t go through backwash cycles, they also don’t create the wastewater that a backwashing filter would. A backwash cycle can use up to 60 gallons per cycle.
Rated service flow rates*

*Stated flow rates are for correct "contact time" to the carbon.
Carbon is a substance that has a long history of being used to absorb impurities and is perhaps the most powerful absorbent known to man. One pound of carbon contains a surface area of roughly 125 acres and can absorb literally thousands of different chemicals. Activated carbon which has a slight electro-positive charge added to it, making it even more attractive to chemicals and impurities.
The two most important factors affecting the efficiency of activated carbon filtration are the amount of carbon in the unit and the amount of time the contaminant spends in contact with it. the more carbon the better. Similarly, the lower the flow rate of the water, the more time contaminants will be in contact with the carbon, and the more absorption that will take place. Particle size also affects removal rates. The most common carbon types used in water filtration are bituminous, wood, and coconut shell carbons. While coconut shell carbon typically costs 20% more than the others, it is generally regarded as the most effective of the three. All of our activated carbon filters use coconut shell carbon.
