The OPROPRE pre-filtration system eliminates 99.9% of the eternal pollutants naturally present in tap water.
Easy to install under the sink, its exclusive combination of ultra-purified activated coconut carbon and high-performance resin delivers purified water with a neutral taste, while preserving the minerals and trace elements naturally present.
It comes with two cartridges that can treat tap water for 1 year or 30m³ of use.
Practical: purified water straight from the tap
Economical: no electricity consumption
Environmentally-friendly: 100% cartridge can be recycled
Delivery: free in mainland France
Dispatch: within 48 hours
The OPROPRE under-sink prefilter combats PFAS, those «eternal pollutants» that are resistant to conventional treatments.
Its technology combines coconut activated carbon and specialised resin to trap PFAS, heavy metals, microplastics and volatile organic compounds before UV-A purification.
Ecological and sustainable, OPROPRE cartridges are returnable, refillable and fully recyclable.

Opropre and purifiers are two complementary treatments.
The coconut resin and activated carbon in Opropre remove PFAS, microplastics and heavy metals, leaving 40% of chlorine in the water. Additional treatment with the LAVIE purifier will :
- remove chlorine and chemical pollutants at the molecular level
- remove any bacteria that might be “living” in the activated carbon cartridge
The Opropre Filter is installed under your sink. The filter holder is 36 cm high, and an additional 4 cm is needed to open it and replace the cartridge: you therefore need a space 40 cm high for installation (horizontally or vertically).
The largest diameter (top of the pre-filter) is 13 cm, so you should consider a diameter of around 17/18 cm with the hoses installed.
We recommend changing the cartridge every 6 months.
This is the sanitary safety period considered by all filter manufacturers.
That said, if you systematically run the water through the LAVIE purifier, for example, which kills 100% of bacteria, it's not “serious” to exceed the time limit.

There is no sieve filtration in our device, so it is impossible to give a size.
The principle of “filtration” is adsorption for activated carbon and ion exchange for PFas resin, which is much more precise and effective than simple meshes.
Yes.
Our entire range is designed to preserve the trace elements present in the water.
You should avoid water that is “over-mineralised”, i.e. with a dry residue of more than 1.2G (1200mg)/l, and especially water rich in nitrates (up to 50 mg/l, but tap water above this is declared undrinkable).
So, in principle, if these two criteria are met in your tap water, you can use tap water for infants and we also recommend using the LAVIE purifier for the same reasons as above.
Many mothers have already made this choice.
Yes, absolutely.
The Opropre filter is effective against most “hard” and “everlasting” pesticides, such as Pfas, Chlorothalonil, volatile organic compounds (VOCs), ESA and OXA metolachlores, endocrine disruptors (EDs), chlordecone, etc.
Absolutely.
Simply disconnect the cold water inlet on the tap, screw it onto the filter inlet, then connect the filter outlet to the cold water inlet on your tap.
