Due to the amount of variables involved we try and stay away from using time to determine filter life, instead we use gallons, a more constant form of measurement. Filter life is based solely off of the quality of the water being filtered. The higher the tap water is in dissolved solids the shorter the filter life will be.

After Zero Water filters have been exhausted and have not been changed, the water produced from the filter may have a distinct smell or taste and the TDS reading may be higher than your tap water. This is a result of the water passing over the “spent” Ion Exchange Resin beads. We have gone to great lengths in reducing that taste/smell in product development however this is simply a characteristic of filtering water with a Dual-Ion Exchange system.

In order to avoid a change in the taste of the water it is important to test the water regularly and change the filter when the digital meter reads 006.

From time to time, a filter may develop an air bubble or air pocket. Carefully lift the reservoir, grip the body of the filter at its mid-section and give the filter 4-5 squeezes while there is water filtering through. This will return the flow back to its normal state.
