Oasly Verified listing

Oasly is a Barcelona-based water filtration subscription service built for expats, families, and anyone who wants clean, great-tasting drinking water straight from the tap. We specialise in premium reverse osmosis (RO) water filter systems designed specifically for the hard, high-chlorine tap water you find throughout Barcelona and Catalonia. If you've ever wondered whether Barcelona tap water is safe to drink, you're not alone — it's technically drinkable, but the taste, the limescale, and the chlorine put most people off. That's exactly the problem Oasly solves.

Our all-inclusive subscription makes it effortless to upgrade your home's drinking water. For one simple monthly price, we install a modern under-sink reverse osmosis water filter in your kitchen, handle all maintenance, and swap out the filter cartridges on schedule — so you never have to think about it. No up-front cost, no messy DIY, no plastic bottles to lug up five flights of stairs, and no more running to the supermarket for packs of garrafas. Just pure, filtered, mineral-balanced water on demand.

Why expats in Barcelona love Oasly: we speak English, we explain everything clearly, we show up on time, and we take care of the whole process from installation to long-term support. Our reverse osmosis systems remove chlorine, microplastics, heavy metals, limescale, and other impurities while keeping the water fresh and crisp. Better water means better coffee, better cooking, healthier hydration for kids, and dramatically less single-use plastic waste.

Oasly Aqua serves homes and small businesses across Barcelona and the surrounding metropolitan area. Whether you're a new arrival still figuring out the neighbourhood, a long-time expat tired of buying bottled water, or a family that simply wants the best for your household, we make it easy to make the switch. Book a free consultation, pick a plan, and we'll handle the rest.
