How does it work?
LaVie is very easy to use: simply fill the bottle with tap water and place it in its case. An integrated sensor tells the unit to start the purification cycle: the LEDs located all along the case light up and emit a blue light that treats the water. At the end of the treatment, the light goes out and the water is now purified.
Purification consists of removing chlorine and contaminants from tap water. Chlorine and its derivatives, originally used to keep sanitized water in distribution systems, are responsible for bad taste and odour while other substances such as pesticides and traces of drugs can contaminate water and affect health. LaVie uses chlorine as a Trojan horse: the LEDs send UV-A radiation, which triggers a photolysis treatment. Chlorine is eliminated through chain reactions and radicals with high oxidizing power attack contaminants in the water. This eliminates tastes and odours as well as harmful substances, while preserving the trace elements essential for well-being.
What are the limits of use of LaVie?
There is no mechanical filtration of any physical particles present in the water. Our product is therefore not intended to treat water containing mud, sand, faeces, salts...
In the same way, our product has no effect on radioactivity and radioelements.
LaVie is intended to enhance the quality of tap water that is originally potable.
Effectiveness of our product - publication of laboratory test results
LaVie permits the removal of chlorine, glyphosate, contaminants and traces of drugs as well as the sterilization of water.
What is the duration of the LaVie treatment?
The default processing time is 15 minutes. In case of unsatisfactory taste at the end of the process, treatment times of 22 and 30 minutes can be selected.
Are UV rays harmful? What are the characteristics of the radiation emitted by LAVIE LEDs?
In small quantities, UV radiation is good for health. On the other hand, in case of overexposure, UV radiation can be responsible for skin, eye and immune pathology.
There are 3 different types of UV: UVA, UVB and UVC.
UVAs correspond to radiations of wavelengths from 315 to 400 nm. They are not harmful for humans. They represent about 95% of the UV rays that reach Earth. They are responsible for the immediate tanning effect. In case of excessive and repeated exposures, they are harmful in the long term because they boost the skin aging.
UVB radiation corresponds to wavelengths from 280 to 315 nm. They have significant biological activity. They are responsible for tanning and delayed sunburns ; in addition to these short-term effects, they promote skin aging and skin cancers.
UVC corresponds to radiations of wavelengths from 100 to 280 nm. This is the most dangerous type of UV. One of their targets is DNA, they have a very important carcinogenic potential and they burn the epidermis very quickly. Fortunately, they are filtered by the ozone layer before they reach the earth. They are therefore found only by artificial sources such as germicidal lamps. Those devices need to be used with great care.
The LEDs used in LaVie only emit UV-A and visible light
For treating and disinfecting water with UV, UV-C or UV-B are traditionally used. Our treatment method is innovative because it uses only UV-A rays. Using only UV-A light, our case emits a light that is safe for the user, comparable to the light of the daylight.

What is the ecological impact of a plastic mineral water bottle?
With 700 km of transport and 20 grams of PET, 1 liter of mineral water requires 0.23 liters of petroleum and produces 0.5 kg of CO2.
The annual world market for mineral water in plastic bottles is therefore:
200 billion liters of water
250 million barrels of petroleum
100 million tons of CO2
Can you tell us more about plastic pollution of the oceans?
Pollution of the oceans by plastic is one of the major and urgent problems of our time.
Scientists are warning us that if we continue in this way, in 2050, there could be more plastic in the ocean than fish
How did we get into this mess?
The use of plastics has increased by a factor of 20 in the last half century. This represents an increase from 15 million tons produced in 1964 to 311 million tons in 2014. And that amount could double in the next 20 years.
One third of all plastic waste ends up in nature. Particularly in the oceans, where they form a "seventh continent" which is expected to grow in alarming proportions.
Two things to know about plastic bottles that contribute significantly in generating this pollution:
Every year 100 billion plastic bottles are scattered in nature,
Life expectancy of a plastic waste in nature: between 100 and 1000 years
Approximately 150 million tons of plastics would float in the oceans nowadays. The experts are currently predicting that the oceans should contain one ton of plastic for every three tons of fish in 2025 and more plastic than fish in 2050.
How does LaVie differ from others water treatments?
If compared to Lavie, there is no water treatment device that can filter bad components in the tap water such as chlorine, chloramine, pesticides, etc. without reducing minerals or trace elements.
UV-C reactors destroy bacteria and virus DNA but don’t affect chlorine, or pesticides.
Water purifiers with reverse osmosis technology (RO) destroy all minerals and trace elements, while half of the water input is wasted and dangerous.
Ultrafiltration (UF) eliminates bacteria and virus but slightly reduces the present minerals in the water. In addition, this method is also not active at all about odor, taste and dissolved pollutants.
Filtering jugs also have undeniable benefits for human health. With these water purifiers, there is a huge reduction of minerals and trace elements, while addition of silver oxide is harmful. Furthermore, longer use of the same water purifier without any thorough cleaning can lead to bacteria development in the water storage tank.
Filtering jugs - good solution or not?
Filtering jugs seem to be a good solution for purifying tap water because they filter part of the limestone and lower the chlorine contained in tap water, but according to the French National Sanitary Safety Agency (ANSES), the effectiveness of these jugs is more than doubtful.
Studies show that filters:
are unable to eliminate nitrates.
quickly release various contaminants into drinking water (sodium, potassium, ammonium and silver ions which is a carcinogenic element).
may also lead to a lowering of the pH value or even to a deterioration in the microbiological quality of the water.
ANSES indicates that if they are improperly used, filter jugs become a breeding ground for bacteria. In contrast to what people do, the carafe must be regularly cleaned and the filter must be changed every month to avoid contamination.
Thus filter jugs can be worse than simply drinking untreated tap water.
What arefree radicals?
Free radicals are molecules with unpaired valence electron. These unpaired electrons make free radicals highly reactive towards other substances, or even towards themselves: their molecules will often spontaneously dimerize or polymerize if they meet each other.
When it occurs in the human body, this chain reaction is usually called oxidative stress. In nature, nothing is all right or all wrong. So... if free radicals have an oxidizing power that stimulates aging, our body makes free radicals to defend itself against bacteria and micro-organisms.
With LaVie, chlorine molecule contained in tap water is transformed into ultra-oxidizing radicals, 100 times more oxidizing than chlorine itself.
Through this process, complex molecules are broken down into their simplest elements: carbon, hydrogen, oxygen. This treatment is completely natural, no product is introduced into the water. The degrades organic products (bacteria, viruses, parasites) and chemicals (pesticides, drugs) without affecting minerals.
Note: Free radicals have a very short lifetime (less than 1 second).
After the treatment phase there are no more free radicals in the water.
Chlorine and chlorinated derivatives - what is their impact on health?
Chlorine is added to water distribution systems in the form of bleach or chlorine gas, at the outlet of the treatment plant, to prevent contamination of the water during its journey in systems where contamination is possible, by bacteria (gastroenteritis, salmonellosis) or viruses (gastroenteritis, hepatitis A and E). It is a bactericide that can be used throughout the network and is easy to use.
Chlorine is not harmful, but its derivatives are problematic. However, the risk associated with micro-organisms in the absence of chlorine would be greater than the risk associated with chlorinated derivatives. In order to reduce these by-products as much as possible, other disinfection processes such as ozonation and UV need to be used in addition.
Toxicity of chlorinated derivatives
Chlorinated derivatives are known carcinogens in the WHO IARC classification. The cancers most commonly associated with THMs in drinking water are bladder, rectal and colon cancers.
Access to drinking water in the world?
According to the latest World Health Organization (WHO) report from 2013, 11% of the world's population (768 million people) had no access to safe drinking water in 2011. This causes millions of deaths, mainly due to dysentery.
Among the poorest countries, East Asia and Sub-Saharan Africa are the regions of the world where the situation is most alarming due to structural reasons but also because of the strong increase in population. The continental scale of some countries such as India or China masks huge disparities, especially between rural areas and cities.
Access to fresh will even be one of the geostrategic stakes of the 21st century. That’s why some people do not hesitate to refer to water as the blue gold.
It is urgent to act and manage this precious resource, both for humanitarian reasons and to avoid wars and conflicts.
