Maintenance and Warranty

There are 3 possible reasons for your filter indicator lighting up: (1.) Time (2.) Volume of water filtered (3.) Filter Clogging:

1. If the volume selection - 120ml LED is lit, the cause for your filter indicator lighting being turned on is "Time" (i.e. you have been using your filter bottles for either 4 months or 8 months).
2. If the volume selection - 250ml LED is lit, the cause for your filter indicator lighting being turned on is "Volume" (i.e. you have filtered either 1200L or 2400L of water.)
   You may change the corresponding filter bottle in these 2 above scenarios or monitor till the filter indicator is blinking (100%) before changing.
3. If the volume selection - 550ml LED is lit, the cause for your filter indicator lighting is potentially a water flow issue or clogged filters. Please consult us in this situation.

Note: After the LEDs are on for 3 seconds, the purifier will return to standby mode.

You can find out which of the 3 causes it is when the filter capacity reaches 90%. Press and hold the "Filter" and "Volume" buttons simultaneously.

The Sterra Water Purifier is one of the very few water purifiers that is designed to be extremely self-maintaining. There is no need for you to maintain it in any way, except to change the filters, which is super easy.

Sterra Water Purifiers are built to last. However, in the unlikely event that the water purifier breaks down after a year, we will handle all repairs at a cost that is usually around  $100-$300. The exact figure is dependent on the part that has to be replaced.

Yes, we do offer 1-year warranty for the product.  For the touch panel and leakage, we provide 3-year warranty. Under our current promotion, simply do a photo review of the product and we will upgrade the 3-year warranty for touch panel and leakage to a lifetime warranty!

You can sterilise the nozzle at least once a week. 

Nozzle sterilisation works by pushing the nozzle in. The UV light will then start blinking to indicate that the UV sterilising process is ongoing. The UV light will stop blinking after 30 minutes and become a steady light, indicating that the sterilisation is complete.

Sterra Water Dispenser comes with an automatic filter change indicator on its touch panel. When it’s time to change the filters, Sterra’s filter reminder indicator will light up:

• When it is blinking white, change filter bottle 1 (Pre carbon block).
• When it is blinking yellow, change filter bottle 2 (UF & Post carbon block).

Replacement for the water filter is also designed to be so easy so that you can do it yourself in just a few minutes.

The average usage duration for each bottle is as follows: 

• Pre carbon block filter (bottle 1): Change every 4 months or 1200L of water filtered, whichever comes first
• UF & Post carbon block filter (bottle 2): Change every 8 months or 2400L of water filtered, whichever comes first
