Complete treatment with the Whole House Filter for chlorine taste and odor ICS-TOK is a two-step process.

ICS-TOK filters are our best taste and odor filters. They use two different activated carbon filters which together provide the best removal of the widest array of taste and odor problems. Because water passes through two specialty activated carbon filters it spends more time in contact with activated carbon which by design improves taste and odor filtration more than any other treatment system using activated carbon. The ICS-TO is not recommended as stand-alone treatment for hydrogen sulfide, rotten egg smell or for waters containing chloramine.

For assistance with your treatment system please contact us and we will be happy to help. Maximum service life is 1 year and may be less depending on your water quality and the volume of water treated.
