Reverse osmosis and water filters in Valencia — bottled taste from the tap.
Valencia's tap water is safe; it just doesn't taste like it wants to be drunk. An under-sink osmosis system ends the bottled-water logistics — the carrying, the storing, the plastic — for cents per litre.
In plain terms
Osmosis water filter under the sink — the end of carrying bottles.
A family that drinks bottled water hauls roughly a tonne of it up the stairs each year — and pays bottle prices for what a membrane produces for cents. The system fits under the sink, feeds its own slim faucet, and pays for itself inside the year.

Questions, answered
Osmosis and filters — asked over a glass.
Is Valencia tap water safe without a filter?
Yes — it meets all sanitary standards. Osmosis is about taste and convenience: chlorine, hardness and mineral notes filtered to bottled-water neutrality, at cents per litre.
How much does an osmosis system cost installed?
From €280 with the dedicated faucet and installation. Filter changes are the running cost — stated up front per year, so there are no surprises at service time.
How often do filters and the membrane change?
Pre-filters roughly yearly, the membrane every 2–3 years depending on use and hardness. We schedule it — the system shouldn't depend on anyone's memory.
Does osmosis waste a lot of water?
Modern systems run far leaner than the old horror stories — and we configure them properly. The reject ratio is stated honestly when we propose the model.
Can it feed the fridge or a boiling tap too?
Yes — ice makers, fridge dispensers and combination taps can run from the system. Say so before installation and the layout will be built for it.
Your tap can taste like the bottle.
