How often do I need to replace a water filter jug cartridge?

Most jug filters last between 4 weeks and 2 months depending on the brand and your water hardness. ZeroWater filters may need replacing sooner in hard water areas.

Do water filter jugs remove fluoride?

Standard carbon-based jugs like BRITA do not remove fluoride. ZeroWater is one of the few jug filters certified to reduce fluoride levels.
