Collection: SMR™ Reverse Osmosis

 At Tappwater, we offer the Countertop RO SMR.

 Domestic reverse osmosis systems are the most advanced solution for those seeking excellent quality water at home, without the need for extensive renovations.

 At Tappwater, we present an option that stands shoulder to shoulder with the best on the market: the Countertop RO SMR, a domestic reverse osmosis system that removes contaminants such as chlorine, heavy metals, bacteria, microplastics, and PFAS, while preserving or replenishing essential minerals for your well-being.

 Installing a reverse osmosis filtration system means saying goodbye to plastic bottles, improving the taste of your water, and gaining health and peace of mind.

Did you know that not all purified water contains the essential minerals your body needs?

The Countertop RO SMR™ not only reduces up to 99% of a wide range of contaminants thanks to its reverse osmosis technology, but it also remineralizes the water with Swedish Mineral Rock™, improving its taste and balance.

Unlike standard purified water, this system helps maintain a more pleasant and natural flavour profile, ideal for daily use. At the same time, it offers a more sustainable alternative, reducing the need for bottled water at home.

Frequently Asked Questions about Reverse Osmosis

What is a reverse osmosis system?

A reverse osmosis (RO) system is an advanced water filtration technology that uses a semi-permeable membrane to remove very small contaminants. It can filter particles as small as 0.0001 microns, including dissolved solids, heavy metals, and microplastics, providing highly purified water.

Does reverse osmosis remove minerals from water?

Yes. Reverse osmosis removes not only harmful contaminants but also naturally occurring minerals like calcium and magnesium. While this results in very pure water, it also means the water can lose some beneficial mineral content and flavor complexity.

Difference between water filter and reverse osmosis?

A standard water filter (such as an activated carbon filter) improves taste and reduces common contaminants like chlorine, lead, and microplastics, while retaining beneficial minerals. In contrast, reverse osmosis is a more intensive process that removes a wider range of impurities, including dissolved salts, but also eliminates minerals and usually requires more complex installation.

Does reverse osmosis produce wastewater?

Yes. Reverse osmosis systems generate wastewater during the filtration process. A portion of the incoming water is used to flush away the concentrated contaminants retained by the membrane, making RO less water-efficient compared to other filtration solutions.
