New Upgrade: This water filter features an additional rubber seal layer to prevent unfiltered water from leaking. The filter housing is made of environmentally friendly, food-grade plastic for safe filtration. Multi-layer Filtration: Our water purifier uses a multi-layer filtration system with activated carbon and an ion exchange resin to reduce odors. It contains 30% more resin than standard filters (the yellow substance visible inside is the resin), which helps reduce TDS and remove calcium, magnesium, chlorine, and other ions from water. Note: Filtration performance may vary depending on your water source. Environmental Protection: Each filter can purify up to 40 gallons of water, helping reduce single-use plastic bottle consumption and supporting environmental sustainability. Compatibility: 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, replace the filter every month. If the filtered water develops an off taste or sour flavor, it is time to replace the filter.
