Tap Water Filter: What to Choose?
Table of Contents
Ensuring that you drink high-quality water is an important element for a healthy and balanced life. And we will see that a good tap water filter plays a crucial role in this objective.
Indeed, hydration is crucial for health and the proper functioning of our body. Water plays a vital role in many metabolic processes, including regulating body temperature, digestion, and lubricating joints. This is why it is essential to hydrate with high-quality water.
In France, tap water is perfectly drinkable. However, depending on the regions, its quality can be significantly improved, particularly in terms of taste and smell. This is where your tap water filter comes into play.

Water Filters: Many Models
First of all, note that there are many models of water filters. This proliferation of filtration systems or drinking water treatment options on the market can sometimes confuse or even mislead the consumer. Below are the main ones:
Simple Installation
- Tap filters: These filters attach directly to the tap, filtering the water as it flows. They are generally less expensive than other options. However, they will not remove as many contaminants as other filters.
- Filtering pitchers / Filter carafes: The filter carafes are a portable and convenient option that requires no installation. They traditionally use an activated carbon filter (which we will discuss later) to remove certain contaminants, but their filtration capacity is generally more limited.
- Refrigerator filters: Some refrigerators are equipped with built-in water filters that provide filtered cold water directly from the door.
More Complicated Installation
- Countertop filters: These filters are installed on the kitchen countertop. They are connected to the tap via a hose. They can generally remove a wide range of contaminants.
- Reverse osmosis filtration systems: These systems are usually installed under the sink and use a semi-permeable membrane to remove a wide variety of contaminants, including heavy metals and certain microorganisms.
- Distillation filters: These systems heat water to create steam, which is then cooled and condensed into pure water. They are very effective at removing a wide range of contaminants. However, they are expensive and require more energy than other types of filters.
- Under-sink filters: These filters are installed directly in the plumbing under the sink. They then provide filtered water directly from the tap. They have a higher filtration capacity than tap filters and can remove a wide range of contaminants.

Tap Water Filter: Composition
Now, we need to dive into the heart of the matter and see the elements that make up the filters of the various tap water filtration systems mentioned above.
Activated Carbon
First, note that one of the most widespread water filters on the market is the activated carbon filter. You can find these filters in the cartridges of filter carafes, on the water filters that you attach directly to the tap, or under your sink. Activated carbon filters are often used to eliminate bad odors and tastes from water by removing, for example, some of the chlorine present in tap water. As their name suggests, these filters contain carbon that absorbs impurities.

Ion Exchange
You will also find many water filters that contain ion exchangers. These filters are used to purify water using “ion exchange resins” that have the ability to exchange harmful elements present in the water with beneficial elements present in the resin. Initially, the resins capture the harmful elements, which are then removed from the filter. These filters are found in the various systems mentioned earlier, either alone or in combination with activated carbon, to enhance the overall performance of the filter.
The most advanced models of water filters (such as reverse osmosis systems) use cutting-edge treatment processes to remove the most persistent contaminants such as heavy metals and pesticides. However, these models are generally quite expensive.
Finally, it should be noted that the price varies significantly depending on the type and brand of water filter you choose. Therefore, it will be important to understand your filtering needs before choosing a model.

Disadvantages of Traditional Water Filters
While traditional water filters sometimes represent a solution (often with relative effectiveness as shown by this Que Choisir study on filter carafes!) to improve the quality of the water we consume, they also have certain disadvantages that should not be overlooked.
Thus, domestic water filters have represented a practical and occasionally effective solution for improving the quality of the water we consume for several decades. However, it is becoming increasingly clear that the negative aspects associated with their use lead us to consider new, more sustainable and effective solutions. We will discuss this at the end of the article.
Demanding and Costly Maintenance
Indeed, any domestic filtration system for your drinking water will require regular maintenance.
Over time, particles and impurities will clog your filters. This will reduce their effectiveness and lead to poor water quality.
Moreover, a water filter in poor condition can cause leaks and pressure problems, which can be dangerous to health. Therefore, it is important to clean and replace the filters frequently, such as every month for a filter carafe (Make sure to note this in your calendar!). This obviously represents a cost.
Finally, some filter purifiers such as under-sink osmosis systems can be bulky (and unattractive!) and require space for installation. Thus, it is important to consider these disadvantages when choosing a water filter to ensure that it meets your needs and lifestyle.
Alteration of Water Taste and Odor
It is common for some water filters to alter the taste and odor of water. This can be due to several factors.
First, some filters use materials that can affect the taste and odor of water, such as activated carbon or silver.
Additionally, water may be exposed to high temperatures as it passes through the filter, which can alter its organoleptic properties.
Finally, some filters allow impurities to pass through that can affect the taste and odor of the water.
A Negative Ecological Impact of Water Filters
Water filters have a negative ecological impact for several reasons:
- Use of raw materials: Some water filters require the use of non-renewable raw materials, such as plastics, for their manufacture.
- Production of waste: Used filters or discarded cartridges can generate a large amount of waste that can be difficult to manage. These often end up in oceans and natural spaces, causing significant damage to ecosystems and the species that inhabit them.
- Impact on wastewater: some filters discharge polluting residues into wastewater that can harm ecosystems in waterways or aquifers.
- Carbon footprint: The manufacturing, transport, and use of these filters have a carbon impact that can contribute to climate change.
If you are therefore aware of eco-friendly solutions, it becomes clear that an alternative to using water filters is necessary.
Bottled Water? A False Good Idea
Finally, let’s dismiss the solution of bottled plastic water.
An Alarming Cause of Pollution
Plastic water bottles are among the most polluting product categories. Their production has a significant impact on the environment, and their daily use contributes to ocean and natural space pollution. As the website Save4Planet reminds us, the plastic waste that pollutes our oceans largely comes from plastic water bottles.
Furthermore, this article informs us that 25 million plastic water bottles are used daily in France. This figure places our country in the top 5 worldwide while we have access to drinking water, unlike other countries that genuinely depend on bottled water.
A High Cost
One of the other main disadvantages of plastic water bottles is their high purchase cost. Indeed, bottled water is, as Que Choisir reminds us, 65 times more expensive on average than tap water! If you regularly buy plastic water bottles, this can quickly become costly over the year and weigh on the family budget.
An article from Dauphiné thus informs us that depending on their water consumption, a French household can spend between 200 and 800 euros on bottled water purchases per year, not to mention the unpleasant experience for the back of having to carry hundreds of liters of water.
Despite everything, the market for plastic water bottles remains thriving, particularly due to the growing demand for easily transportable containers.
It is important to raise awareness among users about the consequences of their consumption of these products and encourage them to opt for more sustainable alternatives.
