AlkaFlow™ Filter Replacement Schedule

AlkaFlow™ Filter Replacement Schedule

ALKA-PH Filter Life

The ALKA-PH water filter should be replaced every 360 litres to ensure optimal performance.  Calculate your filter lifetime based on personal consumption and the number of people using the AlkaFlow system, and replace the ALKA-PH filter accordingly.

ALKA-UF Filter Life

The AlkaFlow ultrafiltration cartridge filter has a capacity of 1000 liters, so you only need to change the ALKA-UF cartridge with every 3rd ALKA-PH filter change.

How to Estimate your Usage

To estimate your filtered water consumption, multiply the capacity of your unit (3.5L pitcher or 9L dispenser) by the number of refills you make each week. This will help you project your total consumption and know more accurately when it’s time to replace the filter.

Things to Keep in Mind

  1. Please note that the filter lifetime is indicative.  Areas with contaminated water problems may have to change the filters more often.  Please contact your local authorities for more info about tap water in your area.
  2. When the flow of water slows down and there is an increase in smell/taste of chlorine, it is a clear sign to change your filter. 
  3. It is not advisable to use the ALKA-PH filter longer than 6 months, even if the lifetime calculation may be longer due to low use.
