The Express Water RO5DX Undersink Filter System is a top quality product you can rely upon; getting one for your home will not only provide you with clean drinking but also save you many trips to the doctor.

The use of quality filters is not the only thing that makes the product stand out from the rest. Even the faucet design is a rock. Let’s quickly look at some of the amazing features of this unit.

Quality Filters

Depending on your water feed, the Express Water RO5DX reverse osmosis system can achieve up to 99.99% impurity removal. And this is mainly because of its high quality filters which are staged in a 5-step process.

In addition, the system also comes with an RO membrane that needs to be replaced after two years. A set of spare filters is also included which you can use in replacing the old filters after every 6 months depending on the nature of your water supply. The use of colour coding to distinguish the filters and their casing makes it pretty simple and straightforward to change them.

High Efficiency

An RO filter system is regarded as efficient if it doesn’t use up more than 3 gallons of wastewater to produce 1 gallon of pure water. And for the Express Water RO5DX Under sink system, a pure water ratio of 3:1 doesn’t look bad, especially when compared to the 4:1 ratio peculiar with most RO systems. For certain systems, it could be as bad as a ratio of 24:1 which is terribly wasteful if you ask me. So a ratio of 3:1 for the Express Water RO5DX makes it a highly efficient system which is not only environmentally friendly but also reduces your water bills to a great extent.
