New Upgrade: This water filter features an additional rubber seal layer to prevent unfiltered water from leaking. The filter housing is made from environmentally friendly, food-grade plastic for safe and reliable filtration.Multi-layer Filtration: Our water purifier uses a multi-layer filtration system with activated carbon and an ion exchange resin to reduce odors and improve taste. It contains 30% more ion exchange resin than standard filters (visible as yellow granules inside), helping to effectively reduce TDS, chlorine, calcium, magnesium, and other ions. Note: Filtration performance may vary depending on water source and regional conditions.Eco-Friendly Choice: Each filter can purify up to 40 gallons of water, equivalent to eliminating approximately 500 plastic water bottles (300ml each). This helps reduce plastic waste and supports environmental sustainability.Compatible Models: These replacement filters are compatible with Zero Water pitchers models ZR-001, ZR-003, ZR-004, ZR-006, ZR-008, ZR-012, ZR-017, ZR-600, ZP-007RP, ZD-013W, ZD-013D, ZR-0810G, ZR-0810-4, ZP-010, ZD-010RP, ZS-011RP, ZD-012RP, ZD-20RP, ZD-018, ZD-030RP, ZJ-003, ZJ-004S, ZP-006-4, and ZBD-040-1.For best results, we recommend replacing the filter every month or when the water begins to taste off, indicating the filter has reached capacity.Color: White Material: Plastic and Resin Package Contents: 1 x Water Filter Note: The package includes only the items listed above.
