Other direct-flow systems serve you their worst glass first. Ours doesn't.

Conventional direct-flow reverse osmosis

When you open the tap, the water sitting in the membrane comes out loaded with accumulated osmotic rejection: the first glass arrives with sky-high TDS and inconsistent taste. You have to let the water run… and pour it away.

A Todo Sol system patent pending

Our system eliminates the initial osmotic rejection: stable TDS from the first glass to the last. Open the tap and drink. No waiting, no wasted water, no taste surprises.

Faucet with blue LED light indicating excellent water quality

The faucet tells you your water quality. In real time. With light.

The included faucet features a smart LED light that measures the TDS (total dissolved solids) of the water you are dispensing and tells you instantly:

  • Blue — TDS < 50 · excellent water
  • Yellow — TDS 50–100 · check your filters soon
  • Red — TDS > 100 · time to change filters

Prefer to keep your current faucet? The system can also be installed with your own faucet — you lose the LED indicator light, everything else works exactly the same.

Change both filters in under 1 minute. Timed.

6 filtration stages in just 2 quick-change filters. No tools, no technician, no getting wet.

  1. 1Unplug the unit from the mains
  2. 2Close the water valve
  3. 3Open the side cover
  4. 4Remove the clamps and take out the 2 filters
  5. 5Fit the new ones. Done. ⏱ <1 min
The system's two filters: PAC 1 composite and RO 2 osmotic membrane

The unit also warns you with acoustic indicators when a filter reaches the end of its life. Impossible to forget.

Water in, water out and reject water. Nothing else. The system includes every part and tube you need to install it under the sink or wherever suits you best.

  • Compact and energy efficient

Frequently asked questions

How often do the filters need changing?

The composite filter once a year (€45) and the osmotic membrane every two years (€55). The unit warns you with an acoustic signal when it's time, and the LED faucet confirms it with the colour of the light.

Can I install it myself?

Yes. Installation is simple — water in, water out and reject water — and the system comes with every part and tube. If you prefer, ask us about professional installation.

Does it work with my existing faucet?

Yes: you can install it with your own faucet. You lose the LED water-quality light; the filtration is exactly the same.

What does direct flow 1:1 mean?

Water is filtered on demand (no tank) with a ratio of one litre of reject water per litre filtered — far more efficient than traditional systems, which waste 3–4 litres for every litre you drink.

How long does shipping take? How much does it cost?

We ship to mainland Spain. Shipping costs €9 on orders under €200 and is free from €200.
