Pentek DBC-10EX2 KDF/GAC Combo Filter Video Transcript
Hey everyone, Aquaman here with FilterDoctor.com. Today weíre looking at the Pentek DBC-10EX2.
This is an industry standard size cartridge, approximately 10 inches long by 4 Ĺ inches in diameter, which means itís going to fit into a whole variety of industry standard size whole house filter housings, like for example, the popular Pentek HD-950 that you see here.
Now, the DBC-10EX2 is a granular activated carbon and KDF55 combo filter. KDF is kinetic degradation fluxion; itís a high purity copper zinc alloy thatís very effective at removing water soluble heavy metals like mercury and lead. Itís also extremely good at removing hydrogen sulfide, which most people know as rotten egg smell. Now, you may have tried to remove that with a carbon filter before and found that the carbon filter exhausted very quickly. Thatís because carbon is not the right media of choice for a hydrogen sulfide problem, but KDF is. It is much more effective at removing that nasty smelling rotten egg junk; itís hydrogen sulfide, and this will do the trick on it and for a much longer time period than a typical carbon filter. Now, in addition to that you get the benefits of granular carbon, which removes a vast array of organic and inorganic contaminants.
Now, this is not a whole house filter, I know that might seem strange because of the size, but hereís why. It is an axial flow filter. You see, water enters at the bottom through these slots, rises up through the entire media bed, then reenters the center and goes out the top. This axial flow process creates tremendous flow restriction and pressure loss. If you put this filter in a filter housing in a whole house application, you will suffer very bad pressure loss and flow restriction, to the point where youíre not satisfied with it. The only way this can work in a whole house application is if you have two housings in a parallel configuration, not in series, in parallel. Then you cut the pressure loss in half, and then it will be acceptable.
Determining filter life is extremely difficult for a couple of reasons. One, itís because everybody has unique water conditions, but itís even more complicated with this filter because this filter is typically chosen for really problematic water; water that has a rotten egg smell or has heavy metals is really nasty water and the water chemistry can vary greatly from one situation to the next. So, I canít sit here and be honest with you and tell you it will remove heavy metals for Ďxí number of gallons, or it will remove hydrogen sulfide for Ďxí number of gallons; if I did that, Iíd just be lying. Itís not true. Youíre going to have to put the filter in and simply learn from experience. It may require that you have some easy water testing kits available so that you can test your water periodically until you figure out how long it effectively removes your heavy metal problem. Or, youíll certainly know when itís no longer removing hydrogen sulfide because that rotten egg smell will come back. But learning from experience and then youíll know how long or how many gallons itís good for.
Again, this is the Pentek DBC-10EX2, a KDF55 and granular activated carbon combo filter.
