This filter is a refillable granular CATALYTIC ACTIVATED CARBON filter which is specifically designed to remove chlorine & chloramines from your water.
What's the big deal with CHLORAMINES? About 40% of you reading this have chloramines in your water. No worries, it is a disinfectant just like chlorine but has a ammonia gas molecule so our water companies can disinfect the water across longer distances. Lots of "expensive" filters out there and claims that carbon blocks are the best way to go for point of use....WRONG! Catalytic Activated Carbon is the what the Water Quality Association suggest for point of use.
Fits standard 10" RO & Drinking Water Filter Housings
