Why Use an Alkaline Filter After RO?

Reverse osmosis provides thorough filtration, but the process also reduces many dissolved minerals. An alkaline filter provides a final treatment stage that adds selected minerals back into the filtered water and increases its pH. For this reason, it can complement an RO system when you want more than basic post-carbon filtration.

You can pair this cartridge with our Reverse Osmosis Water Filter for a complete RO-based drinking water setup. If you are building a home filtration system, our Home Drinking Water Filtration System provides another option to consider.

For additional filtration before the RO membrane, you can also use a 5 Micron PP Water Filter. A sediment filter can help protect later filtration stages by removing suspended particles before water reaches the carbon and RO stages.

You can also learn more about how reverse osmosis purifies water and how different filtration stages work together.

A Practical RO Upgrade

If you already have a compatible under-sink RO system, this alkaline water filter provides a simple way to add a mineral and pH adjustment stage. Its compact inline design, 250 L/24-hour maximum flow rate and 3,000-litre stated capacity make it suitable for many household drinking-water applications.
