How to use your Star Water Filter® water filter correctly

A few simple habits are all you need to use your Star Water Filter® system effectively every day: fill it correctly, renew the filtered water regularly and store the filters appropriately when you are away.

A simple everyday routine

A Star Water Filter® system works naturally by gravity. To get the best from it, fill it according to your actual consumption and avoid leaving filtered water standing unnecessarily in the lower chamber.

Ideally, choose a model whose capacity matches your daily consumption so that the filtered water is renewed regularly.

Keep an eye on the water level in the lower chamber

The two chambers are not sealed together. If you completely fill the upper chamber while there is still a significant amount of water in the lower chamber, the system may overflow.

Before adding a large amount of water, always check how much remains in the lower chamber.

Consume filtered water promptly

Filtered water is intended to be consumed promptly: ideally within 24 hours of filtration and within a maximum of 48 hours.

Do not leave filtered water standing in the lower chamber for several days. If it has remained there for more than 48 hours, empty the chamber, clean the system and refill it with suitable water.

Before filling

Check the water remaining in the lower chamber

When no more water comes out of the tap, the lower chamber is not completely empty: a small amount of water naturally remains below tap level.

This residual volume is normal. You simply need to take it into account before filling the upper chamber again.

Good to know: the useful filtered-water capacities of the lower chamber are approximately 5 litres for the Mini Star®, 8 litres for the Big Star® and 12 litres for the Super Star®.
Avoid overfilling

If water is still present above tap level in the lower chamber, do not automatically fill the upper chamber to the top. Adjust the amount added according to the water already present in the system.

Filling

Adjust the filling level to your model

When the lower chamber is genuinely empty, you can completely fill the upper chamber, whatever model you have.

If only the water above tap level has been consumed and the normal residual volume therefore remains at the bottom of the chamber, use the following guidelines:

  • Mini Star®: fill until the tops of the filters are covered.
  • Big Star®: fill to approximately 1 cm above the tops of the filters.
  • Super Star®: leave approximately 1.5 cm of space below the upper rim of the chamber.
Why fill it sufficiently? Regular, adequate filling allows the filters to be used across their full height and helps prevent some areas from remaining out of the water for prolonged periods.

Daily use is ideal when the capacity of your system is properly matched to your household. If necessary, the system can of course be refilled several times during the same day.

Everyday use

Use your filtered water for everyday needs

Filtered water can be used every day for drinking, preparing tea, coffee or herbal infusions, cooking, making soups and other food-related uses that require water.

Boiling water alone does not remove many dissolved chemical contaminants. When you want to use filtered water for cooking or hot drinks, it therefore makes sense to filter it before heating it.

24 to 48 hours maximum

Preferably consume filtered water within 24 hours and within a maximum of 48 hours. In hot weather, renew the water even more frequently.

If you transfer the filtered water to another container, use a clean, closed container, keep it refrigerated and protect it from direct sunlight.

Absence

How should the filters be stored when the system is not in use?

Absence of less than 3 days

Empty any remaining water from both chambers before you leave. The filters can remain installed in the upper chamber.

Absence of 3 to 7 days

Remove the filters from the upper chamber and place them in a properly sealed, airtight storage bag, such as a zip-lock bag. Keep them in the refrigerator.

Never freeze the filters

Store them in an area of the refrigerator where there is no risk of freezing. Freezing can damage the filters and make them unusable.

The bag must be properly closed and completely airtight. Otherwise, the filters may absorb odours present in the refrigerator.

Absence of more than 7 days

For a prolonged absence, the filters must be completely dry before storage.

  • Remove the filters sufficiently early before you leave to allow them to dry completely.
  • Turn them upside down, with the threaded stem pointing downwards, and gently shake them to remove as much water as possible.
  • Leave them to dry completely in this position.
  • Store them in a dry place, protected from light, heat and strong odours.

On your return

Restart your system correctly

After a prolonged storage period, clean the chambers and tap before putting the system back into service.

If the filters have been dried, they must be primed again before use. Follow the steps in our guide to priming and starting your Ultimate Star Filter® elements.

Then carry out the rinsing and restart procedures specified in the user instructions before consuming the filtered water again.

Unused new filters: keep them in their original sealed packaging in a dry place, protected from light, heat, humidity and strong odours until they are used.

What water can be used with your system?

Star Water Filter® is a standalone domestic gravity filtration system. It can be used with tap water, but also with water whose origin and quality are known and which is intended for consumption.

Always follow the precautions stated in the user instructions and the applicable hygiene recommendations.

If you are unsure about water quality

The system should not be considered a sole and automatic treatment solution in the event of suspected microbiological, chemical or accidental contamination.

For water of unknown quality or in the event of a health alert, follow the recommendations issued by the relevant authorities before use.
