Reverse Osmosis

RO filters are so important when it comes to keeping water healthy. If you’re looking for a way to keep contaminants such as: heavy metals, microplastics, and bacteria out of your drinking water, then reverse osmosis filters are the way to go. They filter water to its purest possible form. Plus, on top of getting safe water, you’ll get nice and tasty drinking water too.

Interested in healthier and safer drinking water? Take a look at our range of Brita Compatible Filters to keep your drinking water in tip top shape.

We also have a range of RO filters that can be used in aquariums to keep your ecosystem healthy and functioning optimally too. Tanks and ponds often get a build up of algae which can be damaging to your fish. This is where RO units and other filtering systems come in. Adding one of these units to your tank will save you a lot of trouble, time, and money in the long run and prevent you from having to spend extra money on additives and treatment to get rid of algae build up.
