FAQs - Zenith's filtration technology
Do I really have to change my filter every 6 to 12 months?
As soon as water starts being filtered by our MicroPurity filter, the maximum life of the product is 12 months (depending on frequency of use). After that, contaminants in your drinking water will start increasing as the filter performance declines, which is not always noticeable by taste. You may notice some changes to your HydroTap eg the internal tank inside the HydroTap command centre may start taking longer to fill.
What does the Zenith MicroPurity filter remove?
Our MicroPurity 0.2 micron filtration is certified to reduce chlorine, taste, odour, bacteria, sediment and limescale in line with NSF 42 (aesthetic effects) and Watermark requirements.

I prefer to use compatible filter cartridges in my HydroTap. Why should I use the Zenith filter?
When choosing a water filter for your Zenith product, you need to ensure that it is certified to removing contaminants in your water. A compatible filter may fit into the command centre however if a performance claim is being made, make sure it is also tested and verified to AS/NZS 4348:1995 – this relates to performance testing – it is specific to filters, and it certifies and verifies that your filter will reduce impurities and potentially harmful contaminants.
