Over time, the filter media becomes saturated with impurities and can no longer effectively remove contaminants. This leads to reduced water flow, unpleasant taste, and potential health risks if consumed. Replacing the LT1000P Water Filter every 6 months ensures optimal performance and continued access to fresh, filtered water.
