Why Do We Need Water Purifiers

We are fortunate to have a quality water distribution system at a meagre cost (average non-subscription price: 0.003 euros/l). Although taken from the wild, this water from springs, groundwater or even rivers is monitored, analysed, and treated to make it suitable for consumption according to specific standards. Unfortunately, despite all this, our tap water can sometimes be polluted, occasionally or more regularly by heavy metals, pesticides or other treatments, or drug residues. Sometimes, too, our water is treated so much that it is unpleasant for consumption.


5 Reasons: Why do we need Water Purifiers


With an average of 125 litres per year per capita (or 8.3 billion litres of water per year), French is one of the world’s largest bottled water consumers. But is it really better for health and the environment?

We will not discuss the difference between mineral and spring water here; others have already done so. However, we can ask ourselves about the financial interest with water averaging 0.12 euros/l to 0.50 euros/l. Knowing that it is advisable to drink an average of 1.5 litres of water per day per adult, the bill at the end of the year can quickly become high.

We all know that storing a plastic water bottle from light and heat is very important to prevent microorganisms’ development and that plastic microparticles mix with water. Even though we are cautious about this storage at home, what about throughout the distribution chain? From bottling to the vending machine store to shopping platforms and transport?

Glass bottles can be a solution, but they are much more expensive and, above all, weigh down the already restrictive handling of bottled water.

Similarly, treatment after using plastic bottles is always a problem: we have all seen them during walks in nature, on the banks of rivers or the seas’ shores. We’ve all heard of this 6thTh continent made up of plastics trained in the open sea.




These decanters filter tap water through a cartridge made mainly of activated charcoal that traps chlorine, the largest organic molecules and some pesticides.

With an average capacity of 2-2.5 litres, filtering decanters are attractive because of their beautiful price. Indeed, about thirty euros is enough for the purchase of the carafe. Still, we must not forget the filters that must be changed very regularly or risk giving a reverse result and recharging in organic molecules and pesticides the water you filter (count a hundred euros per year for the normal renewal of the filter of a basic carafe).



Initially used on a large scale, especially for seawater’s desalination, domestic osmoseurs have been common in our homes for about twenty years.

The principle is relatively simple: the water to be treated passes through filters of different natures (sediments, active coals) that discharge it from molecules and particles before passing through an osmotic membrane that finishes ridding it of most of its impurities.

As we can imagine, these different filtrations require a substantial installation on our water supply, carried out by a professional who, most of the time, will also be responsible for the maintenance of the filters. This labour will be in addition to the already relatively large initial purchase price (it takes an average of 1500 to 2000 euros) and the cost of renewing filters.

It should also be remembered that the amount of water needed to clean the membrane should also be taken into account. Indeed, to ensure perfect efficiency, the osmotic membrane is automatically cleaned regularly at “large waters”. This rinse represents for most osmoseurs almost 50% of the total water consumption (for 2 litres of purified water, it takes 1 litre of rinse water) when it is not 1 litre released per 1 litre consumable.

It should also be noted that despite numerous web searches, no manufacturer, both filter carafe and osmosis machine, validate the effectiveness of its devices with concrete test results.



Always looking for products that combine well-being and respect for nature, Carbel has selected the water purifier for its many qualities:

  • Easy installation: no connection to your water main, the device lands where you want. Especially since the water purifier is very aesthetic and space-saving, the only constraint is an electrical connection.
  • Simple to use with a single button to select 3 water temperatures: ambient, warm or warm. Warm water is ideal for preparing baby bottles. Hot water will allow you to prepare your tea or make you an instant soup in seconds.
  • A filtration quality verified by analyses carried out at the Côte d’Or laboratory on tap water (thus presumed consumable) taken from a pesticide-laden area. In summary:

– 72% chlorine and chlorides

– 75% of pollutants and pesticides

– 72% drug residue (and yes, there are some in tap water)

– 37% of volatile organic compounds

  • Also, for the choice of the Dahlert water purifier, Charbel was very attentive to the water consumption required to rinse the osmotic membrane: regular and automatic washing of 10 seconds is programmed, reducing the amount of water released to 0.33 l per 1 consumable litre, thus reducing the cost of operation.
  • The all-in-one filter is only changed when necessary, and there is no risk of forgetting it: light comes on when needed, about once a year (depending on water consumption). One “click”, and here we go again.
