Did you know that something as simple as tap water, once filtered, can radically transform not only the taste of your water but also your daily life? Filtration removes chlorine and impurities that often affect the smell and taste of water, but the benefits don’t stop there.
Beyond more pleasant drinking water, filtration offers less visible but equally substantial advantages: it can revolutionize your diet, optimize the functioning of your household appliances, and even boost the health of your houseplants. Whether it’s making a richly flavored coffee, cooking dishes where the natural flavors of the ingredients are preserved, or caring for your indoor garden, filtered water is a valuable ally.
In this article, we invite you to explore with us the multiple facets of filtered water and how a simple water filter (or a water purifier) can be the key to significantly enriching your everyday life.
Purify tap water for your daily hydration
As we just indicated, purifying your tap water is primarily an essential practice for your daily hydration.
Common contaminants: impact on health and taste
Perhaps you are wondering what is in the tap water that we consume daily. Even though it is generally safe, water can contain contaminants such as chlorine, pesticides, and heavy metals, which not only affect its taste but can also have implications for our health. Filtering water removes these unwanted substances, ensuring that every glass you drink is not only more pleasant to the taste but also safer. A small gesture for a big change, isn’t it?

Environmental and Economic Benefits
By choosing to filter your tap water, you not only reduce your consumption of plastic bottles, but you also save money. Indeed, tap water is at least 100 times cheaper than bottled water. Impressive, isn’t it? Using filters significantly decreases dependence on disposable water bottles, contributing to the reduction of our plastic waste and carbon footprint. Moreover, in the long term, filtering tap water is much less expensive than regularly buying bottled water. It is therefore a choice that benefits both the planet and your wallet.
Domestic applications of filtered water
Now, let’s go further and discover how filtered water, beyond its daily use for consumption, can revolutionize a multitude of aspects of your home life, from cooking to caring for your plants!

Coffee and Tea
The water, which makes up about 98% of coffee or tea, is the key ingredient influencing their quality. The purity of the water is crucial, as it impacts the deployment of flavors. Impurities such as chlorine and heavy metals in tap water can alter the taste and mask the aromatic nuances sought by connoisseurs.
For coffee, it is recommended to use filtered water to eliminate chlorine, allowing for a more effective extraction of aromas without adding undesirable flavors.
Tea, particularly sensitive, also benefits from filtered water to better reveal the richness of the leaves, whether for a vibrant green tea, a complex oolong (or wulong – traditional Chinese tea that lies between green tea and black tea), or a robust black tea. High-quality teas like Japanese white or green teas require absolute purity of water.
Using filtered water significantly improves the taste of coffee and tea while preserving the health of the equipment used.

Cooking of food
The quality of the water used in meal preparation plays a crucial, and often underestimated, role in cooking. For dishes like pasta, rice, and boiled vegetables, water is not just a cooking medium, but an integral component that directly interacts with the food.
Effect on absorbent foods
Pasta, rice, and vegetables are particularly sensitive to the quality of the water used during their cooking. These foods absorb the water in which they cook, thereby incorporating any excess chlorine aftertaste present. By using filtered water, you eliminate these risks, ensuring that the true taste of the food remains pure and unaltered.
Similarly, using filtered water can transform your soups and broths into exceptional culinary creations, enhancing both their clarity and flavor profile.
For recipes requiring a long cooking time or a reduction, such as meat or vegetable broths, using filtered water is crucial. It ensures that the taste of the concentrated ingredients is not compromised by the poor quality of the water.
Importance for the preparation of infant formulas
For infants who largely depend on powdered milk, the quality of the water used to prepare their formula is crucial. Babies have very specific nutritional and safety needs, and filtered water removes the uncertainties associated with tap water quality. By using filtered water, you minimize the risk of exposure to pathogens, heavy metals, pesticide residues, and inorganic impurities that may be present in untreated water.
Mixed drinks, cocktails, and ice cubes

For mixology enthusiasts, the quality of each ingredient plays a crucial role in creating perfect cocktails. Water, often underestimated, is one of those key ingredients. Using filtered water can significantly enhance the clarity and purity of flavors in mixed drinks and cocktails, ensuring that nothing masks or alters the delicate subtleties of the other components.

Premium Ice Cubes
Ice cubes are another crucial aspect of many cocktails. They cool the drink without excessively diluting it, provided they are made correctly. Ice cubes made from filtered water are clearer, free from the perennial chlorine and other impurities, and melt more evenly, which is particularly important for gradually diluted cocktails like the Old Fashioned or Scotch on the Rocks.
Practical tip: To create extra clear ice cubes, boil filtered water before freezing it. This helps to eliminate air bubbles and remaining impurities, producing ice cubes that are not only aesthetic but also super effective, enhancing the appearance and quality of your cocktails!
Use in household appliances
Water plays a crucial role in the daily functioning of many household appliances. Whether it’s coffee machines, kettles, ice makers, or even dishwashers and washing machines, the quality of water can affect both their efficiency and lifespan. Using filtered water is an effective preventive measure to protect these appliances from the harmful effects of hard water and impurities.

Hard water contains high levels of calcium and magnesium, which can deposit and form lime scale in appliances. This lime scale accumulates over time, reducing the efficiency of the appliance and increasing the energy consumption needed to achieve the desired performance. For example, in coffee machines, lime scale can clog pipes and affect the taste of the coffee. In kettles, it can slow down the boiling process and increase energy consumption.
Thus, the regular use of filtered water can significantly extend the lifespan of your household appliances.

Plant Care
Tap water in France contains added chlorine as a disinfectant. However, chlorine can be harmful to plants. For example, chlorine can cause burns on the tips of leaves or premature yellowing. Filtered water, by removing chlorine and other soluble impurities, provides a healthier environment for plant growth. This is especially crucial for indoor plants that rely entirely on you for their hydration and nutrition. Purified water allows for better nutrient absorption available in the soil, promoting more vigorous growth and more abundant blooming.
Solutions for purifying tap water
Well, now that you are convinced of the many household applications of tap water filtration, you are surely wondering what the best way to do it is?!
We will quickly review the best ways to purify tap water, but for more details, we direct you to our guide on the best faucet filter.
Activated carbon filters
Effective at removing chlorine, pesticides, and certain heavy metals, they improve the taste and smell of water. This type of filter is particularly used in filter jugs like Brita. Note that filters must be changed regularly.

Reverse Osmosis Filters
The reverse osmosis systems are highly effective in removing a wide range of contaminants, including fluoride, lead, and other solvents. They are particularly recommended if you are concerned about the extreme purity of water for cooking, drinking, and preparing infant formulas. However, they will also remove beneficial trace elements from your water!
Water Softeners
Although they do not filter contaminants, they treat hard water by removing important minerals such as calcium and magnesium. This is beneficial for prolonging the lifespan of household appliances and improving the effectiveness of detergents. It should be noted, however, that by softening your water excessively, its quality may diminish.
Under-Sink Filters
These systems target the water from a specific tap, making them useful for a point of use such as the kitchen, where the purity of water for drinking and cooking is crucial.
Tap Filters
Easy to install, they purify water directly from the tap and are a convenient solution for quickly obtaining filtered water for drinking and cooking. Generally, they will be slightly less effective than under-sink filters, and like the latter, you will need to replace them regularly.
