KYK^® multi-stage activated carbon filters are among the most advanced in the industry. We also provide a selection of pre-filters from Topway Global for specific water conditions that might affect the optimum performance of your KYK Water Ionizer. Please refer to our Water Problem / Solution Chart to better understand your particular needs and choose the correct prefilter.

Note: All prefilters require a housing. For example, if you order a hard-water prefilter and a re-mineralizing prefilter, you will need a dual housing.
