Reverse Osmosis in Greater Philadelphia, PA

Drinking water for your kitchen. 7-stage filtration with alkaline post-filter.

Professional Reverse Osmosis You Can Count On

For the water you drink and cook with, reverse osmosis is the most thorough treatment. Wellbrook installs under-sink RO systems that push your water through a multi-stage process and a fine membrane, removing dissolved solids, taste, and contaminants that whole-home filtration leaves behind. The result is clean, crisp, bottled-water quality from a dedicated tap.

Our system uses 7-stage filtration with an alkaline post-filter that adds beneficial minerals back for a balanced taste. You get better coffee and tea, clearer ice, better-tasting cooking, and the end of buying and hauling bottled water. We can run a line to your refrigerator and ice maker so they get the same water.

Every system is installed cleanly under the sink by a licensed installer, with the drinking water tested on completion and backed by our lifetime workmanship warranty.

Reverse Osmosis FAQs

What does reverse osmosis remove that filtration doesn't?

RO pushes water through a fine membrane that removes dissolved solids, many contaminants, and the last of the taste that carbon filtration alone leaves behind. It is the highest level of treatment for drinking and cooking water.

What is the alkaline post-filter for?

Pure RO water can taste very clean. The alkaline post-filter adds beneficial minerals back for a fuller, balanced taste, which most people prefer.

Can it connect to my fridge and ice maker?

Yes. We can run an RO line to your refrigerator and ice maker so they get the same clean water as the tap.

How often do the filters need changing?

Pre- and post-filters are typically changed annually and the membrane every few years. We can handle it on a schedule so you never have to track it.
