Our water purification system has been tested by independent laboratories.
The analyses were carried out by the Biotechnological Institute IBIB and Biolineacom.

Specific tests were performed for total coliforms, E. coli ß-glucuronidasa positive, enterococci, Clostridium spores, odour, colour, turbidity, pH, conductivity at 20°C, all dissolved solids, ammonium (NH4), nitrite (NO2), nitrate (NO3 ), bicarbonate (HCO3), total alkalinity (TAC), calcium (Ca), magnesium (Mg), total hardness, free chlorine, Langelier Index.

The pack is supplied as a complete ready-to-install pack and contains everything you need for installation:

  • the filter complete with filter cartridge
  • 2 connectors to screw onto the filter to connect to the 1/4 (6.2mm) tube
  • 2 metres of hose
  • 1 additional 1-way tap

If you don't have a T-connector for the cold water supply to the filter, all you'll need is one (see options further down this page).

Installing the water purifier is fairly straightforward, and can be done easily by a DIY enthusiast without the need for soldering.
All you need to do is connect it to the cold water supply to your tap using our T-fitting, a self-drilling tap or another suitable connection for 1/4" (6.2mm) pipe.

4 in 1 filter operation

Spring water available for everyday use

We offer you the only backwashable filter in the world to date to be completed in the same 4-level filter cartridge. First of all, the water will be treated by a first double filtration which will stop the macromolecules. Then a third filtration with high density activated carbons which will retain the harmfulness of pollutants such as heavy metals, drug residues and pesticides. A 4th filtration step at 0.1 microns thanks to the ultrafiltration membrane will definitively block the way to viruses, bacteria, fungi and others...

In your home, you are guaranteed impeccable water treatment free of viruses, bacteria, pesticides or drug residues.

Unlike osmosis, the process does not alter the natural balance of the water and does not lead to over-consumption. Like all our solutions, this water treatment process is reliable, ecological, economical and easy to use


- Hello, I would like information about your 4-level water filtration device. If I understand correctly once the 7500 liters it is necessary to buy a complete device or can we change only the cartridge?
- Dear customer,
the 7500 litres will be used in 2 - 3 years for about 4 people (7 litres per day x 365 days x 3 years = 7665 litres)
. It will be necessary to replace the cartridge at that time, it costs about 180 euros depending on the price variations and shipping costs are free.


- Hello, for the manual backwashing system could we know more about it, it's to do every how long and how long?
Our answer: backwashing can be done once every 2-3 months using 1 litre of rinsing water. To do this, simply reverse the tap on the top of the filter and drain it from below.
It is not mandatory but will extend the life of your filter.
You will feel the need to change it when you feel the taste and smell of chlorine again. (he treats chlorine.)


- I would also like to treat limescale on my water network as well as chlorine but I didn't see anything for chlorine do you do this product?
Thank you very much.
The answer: For limestone you can choose the solution Suprion + purifier for chlorine. At the beginning of your installation you can install a double water filter that will roughen the quality of your water by treating sediments as well as some heavy metals, chlorine etc....

The advantage of the Suprion is that it is very effective throughout your home network, curative and good value for money.

This system will advantageously replace an osmosis plant!

Indeed, the reverse osmosis units, although very efficient, take up much more space, must also be equipped with a drain. They will consume much more filter cartridges and especially water!
Even with a very good osmosis plant, a litre of purified water is 3 litres of water released into the environment, which is not even recommended to be used for plants since it is loaded with all the undesirable elements of the one that has been purified!

For a quality water without constraints we recommend this 4-step filter.

Very easy to install

Very good product, easy installation
Already installed in the family (with a 3-way faucet) with no worries and works like a charm. This specific faucet is much better than others: spout projection large enough to fill bottles placed in the sink, and vertical lever at rest (does not encroach on the surrounding space).For this new installation, I had to go back to the tightening of the automatic fittings on the filter: the first was too tight (my fault => extruded gasket) and the second not tight enough because a small resistance at the level of the plastic thread of the fitting prevented its tightening by hand even before being in contact. No big deal. My personal recommendation is to lightly grease the joint and the thread near the joint with silicone grease (nothing else). I also recommend placing a mop under the installation to absorb any leaks if the fittings are not tightened properly.

Everything was and is perfect!
Good understanding of the website + Speed and care of delivery + Ease of installation + Prompt phone call back after message + Satisfaction with product use + Very good flow rate = I don't regret having changed my old system from another brand for Biopur. All this, not to mention the fact that the taste and smell of the water are now perfect. Only one small drawback: the instructions could do with being clearer. In conclusion: I recommend it!
