• ZeroWater Filter Replacement Pack: Each filter has an estimated 15 Gallon Filter Life, but filter life can vary depending on water quality. For best results, change your filter when the TDS meter reads 006.
• Advanced Filtration: Our 5-Stage Ion Exchange Replacement Filter removes virtually all dissolved solids (TDS) for the purest tasting water; Total Dissolved Solids are organic and inorganic materials, such as metals, minerals, salts, and ions dissolved in water.
• IAPMO Certified & BPA-Free: Our 5-Stage filter is IAPMO Certified to reduce PFOA/PFOS, lead, chromium, and mercury. All ZeroWater products are made from BPA-Free plastic.
• This Pack Includes: 4 x ZeroWater 5-Stage Replacement Filters with Ion Exchange Technology. Compatible with only ZeroWater systems, NOT the new Culligan ZeroWater systems.
• Less Plastic, More Hydration: You can save up to 110 single-use plastic bottles per filter or up to 660 bottles a year while enjoying the purest tasting water with your Zero Water Filter System.

• Prepare the Filter — Remove the 5-Stage replacement filter from its packaging. Ensure your ZeroWater pitcher or dispenser is clean and ready for the new filter.
• Install the Filter — Remove the old filter. Insert the new ZeroWater filter into the reservoir, ensuring a snug fit. Do not remove the seal until ready to install.
• Flush the System — Fill the reservoir with cold tap water and let it pass through the filter completely. Discard the first 15 liters (approx. 5 gallons) of filtered water to flush the system.
• Monitor and Replace — Use a TDS meter to check water purity. Replace the filter when the TDS reading reaches 006, or after approximately 56.8 liters (15 gallons) of use.
