Landlord worries?
Live in a rented apartment? No problem.
If you can’t drill a hole for the second faucet, we have a clean solution: the 3-way faucet.
Solution 1
We seal the hole
When you move out or no longer need Oasly, we seal the hole with a cover plate—restoring your kitchen perfectly.
Solution 2
Upgrade to a 3-way faucet
Replace your current tap for a 3-way faucet that gives you both filtered and regular water—no drilling needed. Available as a one-time add-on during checkout & it's yours forever!
3-way faucet
No extra hole needed
The 3-way faucet replaces your current tap, so you get filtered + regular water from one place with a clean look and no extra hole. Optional one-time add-on at checkout.

I already have a carbon filter. Isn’t that filtering the water too?
Los filtros de carbón solo mejoran el sabor reduciendo el cloro y algunos olores, pero no retienen contaminantes más pequeños como microplásticos, metales pesados, PFAS o bacterias.
Oasly filtra y después remineraliza el agua, así que lo que sale del grifo está limpio y sabe a agua.

How does the filtration work?
Our advanced reverse osmosis (RO) system purifies your water in two key steps:
1. Filtración ultrafina – El agua pasa por una membrana extremadamente fina, como una rejilla microscópica, que bloquea microplásticos, metales pesados, PFAS y bacterias. Solo pasan las moléculas de agua limpia.
2. Remineralization – Once purified, we add back essential minerals like calcium and magnesium to improve taste and provide optimal hydration and health benefits.
The result? Fresh, mineral-rich water, free from harmful contaminants—just the way it should be.
What is your cancellation policy?
