FAQ about our water purifiers
I have a family. Which purifier suits best to my needs?
You are a big family, choose LaFontaine! 😍 LaFontaine provides you with 5 purified water litres in one go only. If you like the fountain system, this purifier is for you.
LaVie Pure is a perfect fit to families. You can select up to 6 bottles or more and process cycles in a row or whenever you need.
LaVie Premium XL has the same features as LaVie Pure, except that you can insert the sparkling water bottles from your gas machine.
How do I start the water purifier?
Simply place the purifier on a stable surface near an electrical socket, connect the power adaptor to the purifier and then plug it into the mains. The base of the purifier will emit a light that flashes three times (green-green-green) to indicate compatibility with the DC adapter. Your purifier is now ready to use. 😎
Is UV disinfection necessary for my domestic water?
In everyday language, we talk about UV disinfection. It refers to UV-C purification and not the UV-A purification that corresponds to our technology. UV-C acts only against pathogens in the water, preventing them from reproducing. They are effective if you do not have access to drinking water, such as water from a stream. At home, where the tap water is already drinkable, UV-C disinfection is ... unnecessary. 😅 It's like a sword in the water
Is the purifier automatic?
Yes !
Simply place the LaVie bottle in the purifier. A built-in sensor automatically detects the presence of the bottle. The LEDs light up blue all over the purifier.
At the end of the treatment, 15 minutes by default, the LEDs go out. The bottle containing the now purified water can be removed from the case for immediate consumption or placed in the fridge.
How does the purifier work against bacteria and other contaminants?
UV-A radiation causes photolysis of the chlorine. This reaction eliminates the chlorine. This process generates free radicals with strong oxidising power, which attack contaminants in the water (traces of medication, bacteria, traces of pesticides, etc.).
Does the purifier prevent limescale build-up?
Yes 👍
There is no limestone in tap water, just calcium, which is a liquid form and a trace element that is essential for our health.
Our treatment preserves it in its liquid form and gets rid of its bad taste, provided the water is not too hard. Thanks to LaVie, limescale build-up in your household appliances is cut in half!
Is the purifier really worthwhile from an economic point of view?
Thanks to its very low power consumption, the LaVie water purifier lets you purify 1,000 litres of water for around €1.5 worth of electricity. For a family of 2, the purchase pays for itself in 1 year, compared with bottled mineral water. Not bad, is it? 😉
How do I fill the bottle?
On tap, of course! 🤪 Take care not to fill your LaVie bottle to the top: leave 1 or 2 cm of air. During treatment, the water heats up slightly (_1 or 2°C), and if there isn't a little air to allow the water to expand, the pressure created may cause the bottle to break.
Is UV-A light from purifiers dangerous?
No! ✌🏼
The entire device has been validated by SGS for its light safety, because we use UV-A, not B or C. Our safety class even allows you to stare at the light for three hours without retinal damage. Approvals are noted in the leaflet.
Does the LaVie purifier affect the PH of the water?
No 🙅♀️
The quality of your tap water is regulated and subject to health checks. Its pH is legally between 6.5 and 8.5, so there's no need to adjust it.
How should I maintain my LaVie purifier?
No maintenance required 🕺 However, when in use, certain volatiles or dust that are barely visible to the naked eye can settle at the bottom of the tube. These can obstruct the detection lens, forcing you to constantly plug and unplug the device. To get rid of it, simply vacuum the inside of the tube with a small hoover nozzle, or blow it out with a hairdryer, for example. If the problem persists, send us an email at contact@lavie.bio and we'll find a solution together!
How do I set the duration of the purification treatment?
It is not recommended to change the default treatment time of 15 minutes if the chlorine level in your tap water is no higher than around 0.5 mg/l. However, if necessary, you can change the treatment time by keeping the purifier plugged in, without the bottle, and pressing the protected press button on the underside of the purifier with a small pointed object. One click will switch you to 22 minutes of treatment (blue LED), another to 30 minutes (red LED). To return to the initial 15 minutes, click again (green LED).
How long does a LaVie purifier last?
The UV-A LEDs have an over 10 years lifespan (manufacturer's data).
How do I look after my bottles?
The bottles are self-cleaning thanks to the LaVie process. However, we recommend that you wash them once a month in the dishwasher, except for the stopper, to avoid damaging the wood. It's even easier to clean glass with white vinegar or bicarbonate of soda and a little warm water, as long as you don't use abrasive detergents.
What is the shelf life of bottles after LaVie treatment?
Treated and sealed LaVie bottles can be stored for over 6 months, either in the refrigerator or at room temperature. After opening, the WHO recommends consumption within 48 hours.
And filter carafes?
According to the French National Health and Safety Agency (ANSES):
The filters used in filter carafes reduce the PH of the water, degrade the microbiological quality of the water and quickly release contaminants into the water (sodium, potassium, ammonium and silver ions).
Moreover, filter carafes generate plastic and chemical waste.

Can I give LaVie water to my baby?
Yes !
However, it is still important to avoid water that is rich in nitrates or "over-mineralised" (it is useful to consult the https://sante.gouv.fr/sante-et-environnement/eaux/eau website).
