Upgrade: the water filter with an extra layer of rubber seal to prevent unfiltered water from leaking. The housing of the water filter replacement is made of environmentally friendly food-grade plastic, which is -free for safe filtration. Multi-layer filtration: Our water purifiers feature a multi-layer filtration system that uses activated carbon and an ion exchange system to reduce odors. We add 30% more resin than other filters to the ion exchange (if you see a large yellow substance in the filter, that's the resin), which effectively reduces TDS and reduces calcium, magnesium, chlorine, and other ions in the water. Please note: The actual filtration effect is affected by your region. Protect the environment: A Zero water filter replacement can continuously filter approximately 150 liters of water, which can save money on 500 bottles (300 ml bottle) of drinking water. It also reduces the use of plastic and protects the environment. Replacement models: Our Zero water filters are compatible with water pitchers 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. 010RP, ZS-011RP, ZD-012RP, ZD-20RP, ZD-018, ZD-030RP, ZJ-003, ZJ-004S, ZP-006-4, ZBD-040-1. For a fresh drinking water experience, we recommend changing the Zero water filter once a month. When the filtered water starts to taste sour, the water filter has reached its limit and should be replaced.
