Water filters: many models

First of all, there are many different types of water filter. This proliferation of filtration systems or drinking water treatment on the market will sometimes tend to question or even lose the consumer. Here are the main ones:

Simple installation

Filters on taps : These filters attach directly to the tap, filtering the water as it flows. They are generally cheaper than other options. However, they will not remove as many contaminants as other filters.
Filter jugs / Filter carafes : The filter jugs are a portable and practical option that require no installation. They traditionally use an activated carbon filter (more on this later) to remove certain contaminants, but their filtration capacity is generally more limited.
Refrigerator filters : Some fridges have built-in water filters that provide filtered cold water directly from the fridge door.

More complicated installation

Countertop filters : These filters are installed on the kitchen worktop. 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 eliminate a wide range of contaminants, including heavy metals and certain micro-organisms.
Distillation filters : These systems heat water to create steam, which is then cooled and condensed back 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 filter.
Under-sink filters : These filters are installed directly in the pipework under the sink. They then supply filtered water directly from the tap. They have a higher filtration capacity than on-tap filters and can remove a wide range of contaminants.

Tap water filter: composition

Now we need to dive into the heart of the reactor and see the elements that make up the filters in the various tap water filtration systems mentioned above.

Activated carbon

First of all, one of the most widespread water filters on the market is the active charcoal filter. You can find these filters in the cartridges from filter jugson water filters that you attach directly to the tap, or under your sink. The active charcoal filters are often used to eliminate unpleasant odours and tastes from water by, for example, removing some of the chlorine contained in tap water. As their name suggests, these filters contain coal that absorbs impurities.

The ion exchanger

You will also find many water filters containing ion exchangers. These filters are used to purify the water by using "ion exchange resins"The resins have the ability to exchange the bad elements present in the water with the good elements present in the resin. Initially, the resins capture the bad elements, which are then eliminated from the filter. These filters can be found in the various systems mentioned above, either alone or in combination with activated carbon, to improve the overall performance of the filter.

The most advanced models of water filter (such as the systems with reverse osmosis) use state-of-the-art treatment processes to eliminate the most persistent contaminants, such as heavy metals and pesticides. However, these models are generally quite expensive.

Finally, it should be noted that the prices vary considerably depending on the type and brand of water filter you choose. That's why it's important to understand your water filtering needs before choosing a model.

Disadvantages of conventional water filters

While traditional water filters are sometimes a solution (albeit often relatively effective, as shown in this article), they can also be used to reduce water consumption. Que Choisir study filter carafes!) to improve the quality of the water we drink, they also have certain disadvantages that should not be overlooked.

For several decades, domestic water filters have represented a practical and occasionally effective solution for improving the quality of the water we drink. However, it is becoming increasingly clear that the negative aspects of their use are leading us to consider new, more sustainable solutions and more effective. More on this at the end of the article.

Demanding and costly maintenance

Indeed, all home filtration system of your drinking water will require regular maintenance.

Over time, particles and impurities will clog your filters. This will reduce their effectiveness and will lead to poor water quality.

What's more, a water filter in poor condition can cause leaks and pressure problems, which can be hazardous to your health. That's why it's important to clean and maintain your water filter. replace filters frequentlyThat's every month for a carafe filter, for example (make a note in your calendar!). This obviously represents a cost.

Finally, some filter purifiers, such as sink-mounted osmosis units can be bulky (and unattractive!) and require space to install. So it's important to take these drawbacks into account when choosing a water filter, to make sure it suits your needs and lifestyle.

Changes in the taste and smell of the water

Some water filters often alter the quality of the water. the taste and smell of the water. This can be due to a number of factors.

Firstly, some filters use materials that can affect the taste and smell of the water, such as activated carbon or thesilver.

In addition, the water may be exposed to high temperatures as it passes through the filter, which may alter its organoleptic properties.

Finally, some filters allow impurities to pass through which can affect the taste and smell of the water.

Negative ecological impact of the water filter

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, in their manufacture.
Waste production : Used filters or discarded cartridges can generate large quantities of waste that can be difficult to manage. This often ends up in oceans and natural areas, causing significant damage to ecosystems and the species that live there.
Impact on wastewater : Some filters release pollutant residues into wastewater that can harm ecosystems in rivers or groundwater.
Carbon footprint : The manufacture, transport and use of these filters have a carbon impact that can contribute to climate change.

So if you are aware of eco-friendly solutionsIt's clear that an alternative to water filters is needed.

Bottled water? A bad idea

Finally, let's get rid of the plastic bottled water solution.

An alarming cause of pollution

The plastic water bottles are among the most polluting product categories. Their manufacture has a major impact on the environment, and their daily use contributes to the pollution of oceans and natural areas. As the Save4Planet The plastic waste polluting our oceans comes largely from plastic water bottles.

The article also states that 25 million plastic water bottles are used every day in France. This figure places our country in the world's top 5 even though we have access to drinking water, unlike other countries that rely heavily on bottled water.

A high cost

One of the other main disadvantages of plastic water bottles is their high purchase price. Bottled water is, as we are reminded once again What to choose is 65 times more expensive on average than tap water! If you regularly buy plastic water bottles, this can quickly become expensive over the year and put a strain on the family budget.

An article in Dauphiné shows that depending on their water consumption, French households can spend between 200 and 800 euros in bottled water purchases per year, not to mention the unpleasant experience for the back of having to carry around hundreds of litres of water.

Despite this, the market for plastic water bottles is still flourishing, not least because of the growing demand for easily transportable sizes.

It is important to make users aware of the consequences of their consumption of these products and to encourage them to opt for more sustainable alternatives.
