Stage 2 – 5 Micron Standard Low Alkaline Cartridge

The second cartridge in this water filtration system is designed to add beneficial minerals back into treated city or town water, elevate the pH level and enhance the overall taste. While municipal water is treated to make it safe to drink, the treatment process can strip the water of naturally occurring minerals and often leave it tasting flat or chemically.
As the water flows through the Low Alkaline cartridge, it passes through calcite and corosex minerals which help raise the pH level closer to a healthy neutral or slightly alkaline level while adding essential minerals such as calcium and magnesium back into the water. These minerals not only improve the taste of the water but also support everyday wellbeing and hydration.
The final stage inside this cartridge is carbon for polishing up the water, which helps reduce unwanted tastes and odours commonly found in treated water supplies, including chlorine. The result is fresh, clean, mineral-enhanced drinking water that tastes smooth, refreshing and is ideal for everyday consumption.
World-Class Filtration With Minerals Retained
Unlike reverse osmosis, this system retains healthy minerals while removing dangerous contaminants. The advanced filtration ensures purity while preserving the good.
Test & Certification
-
NSF/ANSI 42 & 53: Tested to both standards for aesthetic and health effects.
-
NSF/ANSI 401: Performance validated to both standards for emerging contaminants and incidental compounds.
-
Quality Assured: Manufactured in an ISO9001 certified facility with performance validated by independent laboratories.
Capacity
To guarantee performance, the ULTRAPURE City Water Purifier cartridge and the Alkaline cartridge have an estimated service life of 12 to 18 months or 3000 litres, whichever comes first, depending on water quality and usage. Signs for replacement include changes in water taste, odour, or pressure.
Maintenance and Replacement of Cartridges
-
Replacement Interval: Replace cartridges every 12 - 18 months or sooner if water flow slows significantly or taste changes.
-
First Use: Flush the new cartridge with water for 5 minutes before drinking to remove any carbon fines.
-
Storage: Store in a cool, dry place. Operates within a temperature range of 5 - 38°C.
