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 utilizes 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 compared to similar filters (the yellow substance visible inside is the resin), which helps reduce TDS and removes calcium, magnesium, chlorine, and other ions from water. Note: Filtration performance may vary depending on regional water conditions. Protect the Environment: Each filter can purify approximately 40 gallons of water, helping reduce plastic bottle usage and supporting environmental conservation. Replacement Compatibility: These water filters are compatible with the following pitcher 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, ZBD-040-1. For optimal performance and best-tasting water, we recommend replacing the filter every month. Replace the filter when the water begins to taste off or develops an unusual odor.
