Between bottled water, which is polluting because of the plastic it contains, and tap water, which raises doubts about its composition, the filtering carafe is the obvious choice. the solution for purifying your water and enjoy healthier hydration. But are they all really effective? Well, no. Some are inefficient, costly, harmful to the planet, and even a source of new undesirable elements in your glass.
Fortunately, nature inspires more reliable alternatives. And LAVIE understands this. There's an innovative solution: LAVIE purifiers, jugs without filters which use UV-A light to purify tap water.
What if the best carafe filter didn't use a filter at all?
The operation of a classic filter carafe such as the one from Brita, Philips or others that you can find on the market, particularly on Amazonis based on one component: its cartridge. It is this cartridge which, with a mixture of components, promises to purify tap water.
Inside, there are two types of beads: those made of activated carbon and others made of ion exchange resins. Thanks to its ultra-porous structure, activated carbon is able to retain certain impurities such as chlorine, organic residues and pesticides. The resins act on the mineral salts (calcium/magnesium) by substituting them with table salt (sodium). All this is enclosed in a plastic block enriched with silver particles to limit bacterial growth.
All you have to do is pour the tap water into the upper part of the carafe. It then flows through the filter into the lower reservoir. In just a few minutes, you'll have water that's supposed to be healthier.
But, as we shall see, it's not all so clear-cut.
On paper, filter carafes look reassuring. But in everyday use, they can sometimes do more harm than good. L'ANSES and theUFC Que Choisir alert If the carafe is not maintained (filter not replaced on time, irregular cleaning, water kept for too long), it can become "overloaded". a veritable breeding ground for bacteria.
Why should we do this? Because filtering out chlorine, water's natural disinfectant, also removes the barrier against microbes. The result: water that's supposed to be purified Bacteria can proliferate as early as 24 to 48 hours after filtration.
And that's not all! A neglected carafe can also release undesirable substances such as silver, sodium and ammonium, while depleting the water of calcium and magnesium, two minerals that are essential to your equilibrium. The pH thus becomes acidic.
What was supposed to be a feel-good gesture alter water quality you drink every day.
While conventional filter jugs may seem more environmentally friendly than bottled water, their environmental impact remains questionable. The use of disposable filters, which have to be changed every 3 to 5 weeks, generates a significant amount of waste. plastic waste never recycled. Once saturated with pollutants, these filters end up in the bin. In other words, we're shifting the problem without solving it.
Another point not to be overlooked is the presence of microplastics. Over time, the plastic materials in the carafe and filter can release them into the water. These particles find their way into your water, and therefore into your body. It's a sobering thought, especially when you're paying the price and trying to protect your health on a daily basis.
What if there was a simpler, more effective, more environmentally-friendly alternative that was better for your body? Let's discover the LAVIE filterless carafe.
La LAVIE filter carafe is based on an innovative purification technology, inspired by nature and validated by science (see the scientific advice from LAVIE). No change of filter here: these are UV-A rays which purify drinking water from the tap within 15 minutes.
When it passes through the glass bottle, this light triggers a phenomenon called photolysis. In other words, chlorine, which is naturally present in water, is transformed into reactive radicals with the ability to neutralise various contaminants such as pesticides, drug residues and bacteria.
Once their action is complete, these radicals disappear, leaving pure waterIt has no off-flavours and is perfectly safe to eat.
This process, which is both gentle and extremely effective, uses only no filters or chemicals and preserves minerals such as calcium and magnesium, which are essential to your health.
Contrary to appearances, conventional filter carafes (Brita, Philips, Amazon...) are not without their faults. While they reduce certain pollutants through the cartridge, they also remove up to 90 % of calcium and magnesium, two minerals essential to our bodies. What's more, their disposable filters can release unwanted ions such as sodium, silver and ammonium, while acidifying the pH of the water. So, unbalanced water can sometimes more corrosive and an altered taste.
Faced with these limitations, the LAVIE decanter offers a alternative to the carafe filternatural and effective. Thanks to its UV-A technology, it neutralises pollutants (chlorine, pesticides, drug residues, bacteria), while preserving 100 % of essential elementsNo leaching, no chemicals. What's more, there's no more limescale build-up inside the decanter.
Backed up by tests: the indicator shows that 100 % of bacteria are eliminatedmore 50 % of glyphosate reductionAnd that's just one of the many positive results and opinions.
In short: where conventional filters weaken water, LAVIE enhances it.
With LAVIE, every sip counts triple. For health Firstly: no more filters to harbour bacteria, no more undesirable residues or essential minerals removed. The water remains healthy, balanced and pleasant to drink every day.
For the budget then: no more expensive filters to buy each month or packs to carry and store. Once you've bought the carafe, purification becomes free, day after day.
And finally for ecology Zero disposable plastic, zero recurring waste, a practical glass bottle and a system designed to last for many years.
LAVIE is a beneficial change for those who want to consume better, while taking care of themselves and the planet.
When it comes to purifying drinking water from the tap, there are two opposing approaches: conventional carafes, with their cartridges that need changing, and the LAVIE filter carafe, based on filter-free UV-A technology. So which should you choose? Let's take a closer look at these two methods to help you make the best purchase.
| Criteria | Classic carafe filter | LAVIE decanter |
| Chlorine filtration | Yes, but it diminishes over time |   Yes, by photolysis of chlorine |
| Elimination of bacteria | May encourage their proliferation | Â Yes, 100 % of bacteria eliminated |
| Mineral preservation | No (down to -90 % of calcium and magnesium) | Â Yes, 100 % preserved |
| Risk of release | Yes (silver, ammonium, sodium ions...) | Â No |
| Alteration of pH | Yes (more acidic water, pH < 6) | Â No (neutral pH maintained) |
| Filtration time | Slow and in several stages | Â 15 min with 6s filling |
| Maintenance | Yes (weekly cleaning + 3-5 week filter change) |  No maintenance |
| Cost | High long-term (filters to be replaced) | Â Economical (no consumables) |
| Ecological impact | Negative (disposable filters, plastic waste) | Â Zero waste / zero plastic |
When you compare the two systems, the difference is obvious. Classic decanters (Brita, Philips or even Amazon) filter, but at the cost of numerous compromises: monthly filter changes, loss of essential minerals, risks of bacterial proliferation and production of plastic waste. Not to mention the significant recurring cost of buying cartridges.
LAVIE, on the other hand, takes a radically different approach: purification by UV-A lightThis patented technology neutralises pollutants, preserves the necessary elements and reduces limescale build-up. This patented technology neutralises pollutants, preserves 100 % of necessary elements and reduces limescale formation. Sustainable, economical and caring, LAVIE is a real game-changer.
Before choosing a carafe or water purifier, it's best to think about your real needs. The first question to ask yourself is: how much water do you need? quality of my tap water? If it contains chlorineand pesticides or drug residuesA high-performance purification system is essential.
Next, determine the budget you want to spend on a reliable, long-lasting solution. Also consider the capacity required for your household, ease of maintenance and energy consumption.
Finally, check whether the product is easy to use on a daily basis and whether it fits in with your lifestyle. By asking yourself these questions, you can choose the model that suits you best.
 At LAVIE, each model has a specific use, so that everyone can find the carafe best suited to their needs:
With LAVIE, there's always a solution to suit your pace, your environment and your well-being.
In France, tap water is under serious scrutiny and its quality is reassuring. Every year, more than 324,000 samples are taken, and more than 17 million analyses are carried out, to monitor a wide range of parameters.
According to 2023 summary on the quality of tap water, published by the Ministry of Health and Prevention in conjunction with the ARS, 98.4 % of the population receives water that is microbiologically adequate, and compliance reaches 99.5 % for nitrates and 74.7 % for pesticides.
But compliant does not mean free of all traces. Chlorine, nitrates, pesticides and endocrine disruptors may still be present, in very small quantities, but on a regular basis. And in certain rural or agricultural areas, their rate may be higher. L'use of a water filter is therefore a necessary reflex for gaining peace of mind on a daily basis.

Adopting a water filter jug is a simple gesture, but one that has a major impact. By filtering out impurities, chlorine residues, traces of pesticides, medicines and bacteria, you reduce your exposure to these undesirable substances every day. And with a technology like LAVIE's, which preserves the minerals that are essential to your body, you can take full advantage of your body's natural resources. taking care of your health. It's also a real pleasure to drink every day: no more chlorine taste, just soft, healthy, pleasant filtered water. You'll drink more, that's for sure!
But the benefits go far beyond that: there's no longer any need to buy heavy, bulky, polluting plastic bottles. The result: less waste, less expense and more freedom.
Not all decanters are created equal. And more importantly, none of them filter absolutely everything. Some promise wonders, but in reality they only filter on the surface. Here's the proof: in our video test, a drop of methylene blue is added to two decanters: a standard market decanter and the LAVIE decanter. Fifteen minutes later, the water remained coloured in the first. In the LAVIE jug, however, it became completely clear. Why does this happen? Because LAVIE goes further.
Thanks to its UV-A technology, it eliminates chlorine, pesticides, drug residues and bacteria, while preserving the good minerals.
But even this, like all the others on the market, has its limits. Some pollutants, including PFAS ('eternal pollutants'), heavy metals and nanoplastics, are resistant to this type of purification.
That's why LAVIE has come up with a global solution to accompany the LAVIE decanter:
Together, they provide ultra-pure, healthy water for your entire household.
Drinking filtered water is all about making a choice safer water and gentler on your health. By reducing residues of chlorine, pesticides or medicines, filtration limits exposure to substances that are harmful to your body. What's more, no more plastic bottles to carry around. But be warned: not all methods are created equal.
Some conventional carafes also eliminate essential minerals such as calcium and magnesium (up to 90 % lost), which are vital to the body's equilibrium. Others can release unwanted ions, or become a veritable breeding ground for bacteria if the filters are not changed in time. The result: unbalanced water, sometimes more harmful than beneficial.
Conversely, LAVIE products purify without altering the natural richness of the water. Now you can filtered water that's healthy and pleasant to drink thanks to our decanter.
If we compare conventional systems and LAVIE decanters, the conclusion is clear: UV-A technology wins the day with flying colours. It's the best carafe filter! Healthier, more sustainable, more respectful of your equilibrium and the environment, LAVIE purifies tap water without reducing its benefits.
No more disposable filters, essential minerals removed or invisible contaminants left behind. With LAVIE models, you're opting for an innovative, simple, natural and effective change that takes care of you and the planet.
In short, you're choosing a decanter designed for today and tomorrow.
Classic filter carafes with cartridges feature several limitations They often remove up to 90 % of essential minerals such as calcium and magnesium, sometimes releasing undesirable ions (silver, sodium, etc.), produce plastic waste and can encourage the development of bacteria if the filter is poorly maintained. The result: water that is unbalanced and less beneficial.
Classic carafes with cartridges, such as those from Brita, Philips or others that you can find on the market, such as AmazonThese act mainly on chlorine and mineral salts. Conversely, LAVIE models, thanks to UV-A technology, will further in water filtration They effectively neutralise chlorine, pesticides, drug residues and bacteria. And with Opropre, even PFAS, heavy metals and microplastics are filtered at source.
The use of glass remains the best option for your filtered water: sustainable, ecological and healthy, it doesn't alter the taste or quality of the water. What's more, unlike plastic, it does not release any undesirable substances such as microplastics into the carafe. That's why all LAVIE decanters are made from laboratory-quality tempered glass (borosilicate or "Pyrex"), a hard-wearing material that is kind to your body and the environment.
Yes, much better than plastic bottles, but beware of the models! While some classic carafes filter out certain impurities and chlorine thanks to the cartridge, they can also remove up to 90 % of good minerals or become a breeding ground for bacteria if filters are poorly maintained. Also, because they are made of plastic, they can release undesirable substances. LAVIE carafes, on the other hand, purify without compromise: they retain essential minerals, require no disposable filters and are made from glass, a healthy and durable material. The result: you choose water that's pure, soft and perfectly balanced, day after day.
