I've had NOVA Filteation systems in my 2 homes. The 1st was installed over 3 years ago. When Bob changed out the filter he indicated ever though there were not completely dirty, he changed them out as bacteria could form in he filters. He recommended changing them out at the most every 18 months or sooner with heavy year around ussage. When I bought my recent house, I had Bob install the unit before we moved it. IMO this unit is the best singular best improvement one can add to their home!
