FOUR Stage – Reverse Osmosis Home Filtration System 50GPD

For anyone looking to purify their drinking water, or brew their own beer/wine/coffee, a Reverse Osmosis Filtration System is the best option.

Reverse osmosis filtration system thin-film RO membrane filter reaching 0.0001 micron, cutting back 99% of contaminants and solids. Such as heavy metal arsenic, lead, mercury, fluoride, calcium, chlorine – will also remove bacterium, odors, and bad taste.


Removes 99% of contaminants and solids, for safe and clean water.

Why Brew with RO water?

In countries like Australia, tap water is loaded with chlorine and fluoride as well as other solids picked up from the journey to your home. The overall quality is good and perfectly fine for drinking but provides poor results when involved in fermentation. A reverse osmosis filter strips back virtually all of the total dissolved solids in the water, allowing the brewer to correct the water profile custom to the style of beer, wine, coffee etc.


Stage 1 – 5 Micron Sediment Filter
Sediment filters remove sediment and debris that if allowed to pass through would clog carbon block filters and damage RO membranes. These filters have true step filtration integrated into their design. With 4 separate layers of micron filtration, the outside-in flow allows the outer layer to trap the larger micron particles with a much lower pressure drop.

Step-by-step, trapping the larger particles layer-by-layer, allows these filters a much higher dirt holding capacity than standard spun polypropylene and string wound cartridges.

Stage 2 – 5 Micron Carbon Block
Carbon blocks are manufactured with high purity coconut shell activated carbon. With high performance, great dirt-holding capacity and the absence of carbon fines, they are perfect for use in Reverse Osmosis/Deionisation units, where high chlorine removal is needed.

Stage 3 – Thin Film Composite Membrane
A high quality, thin film composite (TFC) membrane that processes 50 gallons per day. Just some of the water contaminants that these membranes will remove are lead, copper, barium, chromium, mercury, sodium, cadmium, fluoride, nitrite, nitrate, and selenium.

Stage 4 – Mixed Bed Deionization Resin
A mixed bed deionization resin is the final, polishing stage of the RO/DI system. It will remove any contaminants that may have passed through your sediment/carbon filters and RO membrane. This stage will achieve the 0 TDS RO water you need for a successful reef aquarium.

The DI resin is a mixed bed (both cation and anion) with colour changing indicator to let you know when it has become exhausted. The resin starts as a dark blue colour that will turn gold as it becomes exhausted. This gives you a very visual indicator, making sure you know when it is time for it to be replaced.
