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 purifiers utilize a multi-layer filtration system with activated carbon and an ion exchange resin to reduce odors. We include 30% more ion exchange resin compared to other filters (the visible yellow substance 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. Protect the Environment: Each replacement filter can purify approximately 40 gallons of water, equivalent to eliminating the need for about 500 plastic bottles (300ml each) of drinking water. This reduces plastic waste and supports environmental protection. Compatible Models: These zero water filters are compatible with 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 a fresh drinking water experience, we recommend replacing the filter every month. Replace the filter when the water begins to taste sour or develops an off-taste.
