How to choose your Star Water Filter® water filter
Choosing a gravity water filtration system primarily depends on your daily consumption of filtered water, the number of people in your household, and your actual usage. This guide helps you identify the Star Water Filter® model that best fits your needs, without unnecessary oversizing.
How to choose a gravity water filter?
Choosing a gravity water filter mainly depends on three criteria: the number of people in the household, daily filtered water consumption and culinary uses.
A well-sized system ensures that you always have enough filtered water available while maintaining simple and comfortable daily use.
- 1 to 2 people: compact system
- 1 to 4 people: versatile format
- 2 to 6 people: more comfortable capacity
How to use this buying guide?
The Star Water Filter® range includes three capacities. The right choice depends not only on the tank volume, but also on your consumption habits, the number of people in your household, and uses beyond simple drinking: coffee, tea, cooking, and culinary preparations.
- Mini Star : suitable for the most compact needs.
- Big Star : a versatile format for most households.
- Super Star : a more comfortable capacity for higher usage.
- The right model is the one that allows you to consume filtered water under appropriate usage conditions.
- A larger capacity is not always an advantage.
Usage-guided choice Rational decision Accessories depending on desired comfort
Choosing without oversizing
The right model is not necessarily the largest
A gravity water filter should allow you to have access to a quantity of filtered water consistent with your daily consumption. The goal is not only to have a large capacity, but to choose a system adapted to your actual usage rhythm.
- Capacity too small : you will need to refill the system more often.
- Capacity too large : you may unnecessarily slow down the turnover of filtered water.
- Right choice : a balance between capacity, daily usage and refilling comfort.
Filtered water should be consumed under appropriate usage conditions. This guide aims to help you choose a capacity that makes sense, rather than automatically directing you to the largest model.

Choosing the model
How to choose the right capacity?
The choice of system depends on the amount of filtered water you want to have available on a daily basis, but also on how you use this water. A well-chosen model is one that is adapted to your actual usage rhythm, without unnecessary oversizing.
If you choose a capacity that is too small
You will need to refill the system more often during the day. This is not necessarily a problem, but it may reduce ease of use depending on your daily routine.
If you choose a capacity that is too large
You may end up choosing a capacity greater than your actual needs. In that case, the system may be less appropriately sized for your everyday usage.

Estimating your needs
How to estimate your daily filtered water needs?
Your needs do not depend only on the water you drink by the glass. Filtered water can also be used for hot beverages, cooking, or certain culinary preparations.
- Number of people in the household
- Consumption habits that may vary from one household to another
- Uses beyond cold drinking water: tea, coffee, herbal infusions, cooking, soups
Boiling water does not in itself remove the pollutants it may contain. Choosing a filtration system should therefore not be based solely on water consumed directly as a drink.
Simple guideline: it is generally better to choose a model whose capacity is consistent with your actual needs, rather than selecting a volume that greatly exceeds your usage. A well-sized system integrates more naturally into everyday routines.
What is a gravity water filter?
A gravity water filter is a filtration system that uses the natural force of gravity to allow water to pass through filtering elements. The water slowly flows through the filters and is collected in a lower chamber ready to be consumed.
This type of system operates without electricity, without pressure and without any connection to the water supply.

Available accessories
All Star Water Filter® systems are delivered with a stainless steel tap matching the selected finish. Some accessories can improve everyday ease of use.
Level tap
It allows you to easily see the level of filtered water available in the lower chamber.
Stand

Choosing accessories according to your setup
The purpose of accessories is not to change the system’s performance, but to improve usability depending on your environment and preferences.
Choosing well means choosing according to your usage
The right Star Water Filter® model is not the one with the largest capacity, but the one that matches your actual consumption, your household, and your daily routine.
This buying guide is designed to help you make a clear, rational and consistent choice. If you are unsure, it is always preferable to seek guidance.
