Usage Tips: Upgrade: The water filter features an additional layer of rubber seal to help prevent unfiltered water from leaking. The filter housing is made of environmentally friendly, food-grade plastic that is BPA-free for safe filtration. Multi-layer Filtration: Our water purifiers include a multi-layer filtration system with activated carbon and an ion exchange resin to reduce odors. This filter contains 30% more ion exchange resin than many other brands (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. Protect the Environment: Each filter can purify approximately 40 gallons of water, helping reduce single-use plastic bottle consumption and supporting environmental conservation. Replacement Models: Compatible with water 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 best results, replace the filter monthly. When the filtered water develops an off taste or odor, it is time to replace the filter.
