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) to effectively reduce chlorine, calcium, magnesium, and other ions. Please note that actual filtration performance may vary depending on water quality in your area.Eco-Friendly Choice: Each filter can purify up to 40 gallons of water, helping reduce plastic bottle waste and supporting environmental conservation.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 optimal performance and fresh-tasting water, we recommend replacing the filter every month or when the water begins to taste off or sour, indicating the filter has reached its capacity.Color: White Material: Plastic + Resin Package Contents: 3 x Water Filters Note: Light reflection and screen settings may cause slight color variations between the image and the actual product.
