It is recommended to replace the water filter cartridges every 6 months to keep your water filtration system working effectively. The filter`s filtration ability is reduced and decreased over time. Filter captured substance will remain inside the filter until new filter is installed.

The NSF notes that most filters either trap contaminants in pores or they adhere to the surface of the media. In either case, the filter will eventually become “full” of contaminants. Once a filter becomes full, water will have a difficult time getting through it and what does get through may not be effectively filtered.
