The under-sink filter that transforms your faucet. Installs in 10 minutes, is invisible, and maintains water flow. Eliminates chlorine to improve taste and removes invisible particles: PFAS, microplastics, and other emerging contaminants. Enjoy a year of healthy water with a reusable filter body. Available in two versions: Essential or Ultra. Say goodbye to bottles and carafes. Rediscover the obvious: your faucet can deliver the best water.
1. Turn off the water
Close the cold water supply valve under your sink.
2. Disconnect the existing hose
Unscrew the pipe that connects your tap to the water supply. Place a basin for the residual water.
3. Reconnect using the supplied hoses.
Screw the first hose onto the cold water supply, the second onto your tap. 3/8 and 1/2 adapters included.
4. Clip on the filter head
Insert the hoses into the connectors until they click. IN for the water supply, OUT to the tap. Replace the blue safety rings.
5. Getting Started
Reopen the valve. Let it run for 3 minutes to activate the cartridge. Your water is ready 💧
👉 1 unscrewing, 2 screwing back in. That's all.
What fluid filters
Your tap water is tested for only 63 elements, while thousands of pollutants can exist in water. Standards can't be changed overnight. But we can be vigilant. And solutions exist to better protect ourselves. Our goal is to provide you with the most advanced solutions on the market, right in your home.
Chlorine
Chlorine
Chlorine is added to water pipes to kill bacteria. While effective for safety, it leaves an unpleasant taste and odor. Our coconut-based activated charcoal completely eliminates chlorine. Say goodbye to bad taste and hello to great-tasting water that makes you want to drink more. NSF/ANSI 42 certified.
The PFAS
The PFAS
PFAS are everywhere: non-stick pans, waterproof clothing, food packaging. These molecules never break down and are found in 96% of French municipalities (UFC-Que Choisir, 2025). There is no official standard in France to limit them. Our patented activated carbon eliminates 99% of the PFAS listed in the most stringent international standard. NSF/ANSI 53 Total PFAS certified — the most demanding certification in the world for these pollutants.
Microplastics
Microplastics
Plastic ages and breaks down into microscopic particles. They're in tap water, bottled water, everywhere. 44% of French pipes are made of PVC, which releases these microplastics over time. Our hollow fiber membranes create a physical barrier of 0.1 microns. Microplastics? Too big, they don't get through. Absolute mechanical filtration.
Bacteria and viruses
Bacteria and viruses
Bacteria can thrive in older pipes, even with chlorine added upstream. A subtle but real health risk. Our hollow fiber membranes eliminate 99.99999999% of bacteria. An absolute physical barrier of 0.1 microns that lets nothing through. The safest water for your family.

THE CONCRETE IMPACT
Monthly comparison
for a family of 4 people
The filter is designed according to the most demanding standards.
A dual filtration system that removes harmful elements while retaining beneficial minerals. Two complementary filtration stages, certified according to the most demanding international standards. Each with a specific role to guarantee you pure water.
Activated charcoal
The chemical magnet
Made from coconut, with a patented ultra-porous structure. It works by adsorption : chemical molecules stick to its surface, like a microscopic magnet.
What it eliminates: Chlorine, PFAS, pesticides and emerging contaminants
What remains
And we keep what matters: your essential minerals . Calcium, magnesium, all those elements your body needs to function. Our system doesn't reverse osmosis: it eliminates pollutants, not the good minerals.
The result? Pure water. Without pollutants. With the right minerals.
Hollow fiber membranes
Physical barrier filtration
Hollow fiber membranes that create a physical barrier of 0.1 micron . To give you an idea: a human hair is 70 µm.
What they block: Microplastics, bacteria, sediment, rust…

Frequently Asked Questions
How does Fluide work?
Fluide uses a professional double filtration system: a specially reinforced activated carbon block to remove chlorine, pesticides, pharmaceutical residues, and PFAS, followed by a hollow fiber membrane that blocks bacteria, microplastics, and particles down to 0.1 micron. Beneficial minerals are preserved. The water flows at normal tap pressure, without electricity, without a tank, and without waste.
Is this fluid compatible with my sink?
Yes, Fluide connects to the cold water supply, before your faucet. It works regardless of the type of faucet you have. One important point to note: the filter body is 37 cm tall. If you have shelves or a lot of storage under your sink, you may need to reorganize the space. You can mount the system to the wall or cabinet to maximize space.
What are Fluide's approvals?
The Ultra Invisible Filter meets NSF 42, NSF 53 Total PFAS, and NSF 401 standards, as tested by an independent laboratory. The combination of NSF 53 Total PFAS and NSF 401 is rare on the market. Many filters only meet NSF 42 (taste and odor), but we go much further: proven elimination of PFAS, pesticides, and pharmaceutical residues.
What is the purpose of the subscription?
Subscription means peace of mind: your cartridges arrive automatically every year, without you having to think about it. You benefit from a 10% discount on your filter the first year, a 15% discount on all subsequent replacements, and a lifetime warranty on the entire system, except for the seals, for the duration of your subscription. You can cancel at any time, with no commitment and no hidden fees.
Is it complicated to install?
Installation takes 10 minutes, no plumber required; all you need is an adjustable wrench: one unscrew, two screw back in, that's it. If you want to attach the filter body to the cabinet or wall to optimize your space, allow 15 minutes.
When should the cartridges be replaced?
Every 12 months. We'll send you an email reminder before the due date. Replacement takes 5 minutes and requires no tools. The entire system remains the same; only the filter needs to be changed. When you receive your new filter, we'll provide a return system: you send the old one back to us, along with all the pollutants it has captured, and we'll take care of the recycling.
