Whole House Water Filter Systems for Chlorine and Chloramines, Part II

Welcome back to our series on home chlorine and chloramine removal.  On Monday we discussed downflow, auto-backwashing carbon filters; today we’ll take a look at upflow, non-backwashing carbon filters.

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.

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 is. However, because upflow carbon filters don’t go through backwash cycles, they also don’t create the wastewater that a backwashing filter would.

For chloramine removal, we generally recommend Aquasorb upflow systems.  The Jacobi Aquasorb CX-MCA is a 12 x 40 catalytic, granular, coconut shell-based activated carbon that is highly effective at removing chloramines due to its large micropore volume and superior mechanical hardness, while the upflow filter systems themselves are a bit easier and less expensive to install.  This is because there is no need to hook an upflow filter to a drain line, since, as mentioned above, these filters do not backwash themselves and thus do not create wastewater.  And because the valve used for an Aquasorb system does not require power, these systems can be installed even if you do not have a power outlet near your plumbing system.

If you do not want an upflow or downflow carbon filter, you still have another option in carbon filter cartridges. These are even less expensive than an upflow filter, initially, though they will eventually become more costly as you replace the cartridges over time.

On Friday we will post the last part in this week’s series on home chlorine and chloramine removal methods, in which we’ll discuss carbon filter cartridges a bit more.  For now, though, we’ll leave you with some more information about upflow, non-backwashing carbon filters and carbon filtration in general:

  1. Brian,

    For some city water users, upflow filters can be preferable since they don’t backwash and thus don’t create waste water. We do recommend backwashing filter for chlorine and chloramine removal, however, if the user has somewhere to drain the backwash water. If so, backwashing is preferable as it will clean and reclassify the carbon media, prolonging its life and increasing the effectiveness of your filter.
