Essential to life for humans, animals and plants, water is sometimes polluted or contaminated with pathogens or impurities that could cause disease. When access to a drinking source is not guaranteed, there are natural solutions to purify water—a brief overview of the means available.
If we are lucky enough to have drinking water directly on tap, this is not always the case on holiday or abroad. So what are the tricks to have purer water? Takes stock of ways to purify water.
Purifying water: the devices available and the means on board
There are different ways to filter and purify water, to make it drinkable or acceptable to taste. A quick review.
1 – The different water purifiers
If running water goes through a filtration and purification process before exiting the tap, traces may remain.
For those who want the purest possible water at the end of the tap, you can install a water purifier upstream, under the sink, for example. These systems can use phosphates, an ionization system, activated charcoal, sand filters, chlorine etc.
Carafe filter, the easy solution
If you are afraid of consuming only tap water, you are tired of buying bottles of water, and you still want to have fresh water available, then the carafe is the easiest solution.

All you have to do is run the water into the carafe, and the filter purifies the water from chlorine, tartar, traces of metals etc. This solution is also efficient to preserve appliances from tartar, such as the kettle.
Plus: easy solution, more economical than bottled water, removes bad taste
Cons: requires frequent use, filters to change every 100 litres and to return or bring back to store for recycling
Tap filters, easy and fast
It is less expensive than the filters to install upstream of the faucet, the ones to install on the taps!
Simple to set up, they can hold a cartridge to change every quarter. They retain little limestone, but magnesium and calcium are good for our body!
Plus: very easy to use, inexpensive, more economical than bottled water, removes bad taste
The least: cartridge to be changed regularly and recycled, does not filter the limestone.
The softener filters raw tap water to regulate the concentration of limestone in the water, which then becomes less hard. using water that is softened to extend the life of appliances and pipes.
There are two typesof water softeners:
- resin softeners, which is the most common
- les adoucisseurs au C02, qui ne requierent ni entretien, ni régénération, ni sel
Mechanical devices for travel or hiking?
- Portable water purifiers, equipped with a filter, allow you to purify the water directly pumped into a river, for example.
- Chemical purifiers, in lozenge or liquid, are widespread in the hiking world, and for a good reason: their minimal size is practical when you leave only with a bag! This system is also inexpensive and allows the water to be purified of various contaminants. It is convenient. It nevertheless gives a certain chlorinated taste to the water and is to be used occasionally.
- Portable filters. Membranes, cartridges… Portable filters filter water by removing particles. The smaller the filter’s pores, the more elements it retains, but the longer the process. Relatively efficient and fast, portable filters require real maintenance, not easy when hiking.
The osmosis its
These water filtration systems do not use chemicals or electricity and operate on the principle of reverse osmosis: water first passes through a micro-retention system (0.5 microns) or “sediment filter” that retains any particles (bacteria, micro-pollutant, toxins…), and then passes through an active charcoal filter or “molecular capture”, which eliminates organic matter, pesticides, herbicides that can give an odour or taste to water. Finally, water is found in an electrostatic withdrawal system in the form of a fragile membrane that acts on the water’s electromagnetic surface, eliminating viruses, heavy metals, and hydrocarbons.
Plus: Very efficient, sustainable
Less: Expensive, difficult to install without plumbing skills, removes all minerals from the water, consumes a lot of water (4 litres are discharged for 1 litre of water to consume)
