When should I replace the filter cartridge in my CRYSTAL QUEST Slimline Whole House Water Filter?

[SanLuke]

To keep your water filtration system performing at its best, regular filter cartridge replacement is key. According to the CRYSTAL QUEST Slimline Whole House Water Filter Instruction Manual, here are general replacement guidelines: Sediment filters should be replaced every 12 months, GAC or Carbon Block filters should be replaced every 12 months, and SMART filters should be replaced every 18-24 months. However, always keep an eye on your water. If you notice changes in taste, odor, or color, or if the water flow decreases, replace the filter cartridge sooner. Water usage and water quality can affect how often you need to replace your filters, so keep these factors in mind.
