WaterMark certification for water filters - advice to plumbers, builders, developers
Press | 04-10-19
The WaterMark Scheme is the mandatory certification scheme for plumbing and drainage products which is managed by the Australian Building Codes Board. If a product carries the WaterMark you know that it meets the rules of the WaterMark Certification Scheme which for water filters, includes certification to the relevant Australian Standards.
If pure tasting water and the reduction of impurities and potentially harmful contaminants is important to you and your clients, you should ensure that the WaterMark certification on water filters extends to AS/NZS 4348:1995 to ensure those claims have been tested and verified to the correct standards.
AS/NZS 4348:1995 is specific to filters, as it certifies and verifies that the filter will reduce impurities and potentially harmful contaminants.
You can check if your filter meets both standards by looking at the Performance Data Sheet that is required to be supplied with the filter. See Zenith's Performance Data Sheets listed below.
Zenith's MicroPurity filters will reduce impurities and potentially harmful contaminants larger than 0.2 microns in size – an impurity that small will fit 250 times into a strand of hair.
Our filters are certified to reduce chlorine, taste, odour, bacteria, sediment and limescale in line with NSF 42 (aesthetic effects) and Watermark requirements. Zenith MicroPurity filtration is also certified to deliver a reduction of 99.9% of cysts including cryptosporidium and giardia, 98.9% of lead 8.5 and 99.3% of lead 6.5 to NSF 53 (health effects).
