Is Reverse Osmosis The Best Water Filter?

This is a common question when people first discover how effective Reverse Osmosis Water Filtration is.

And the answer is, MAYBE.

Reverse Osmosis was originally designed for large-scale seawater desalination. The Reverse Osmosis splits the water, removing the majority of dissolved solids. Because of this, about 50% of the water is completely removed and disposed of.

Water Filter VS Reverse Osmosis


An ‘everyday’ activated carbon mechanical water filter will remove contaminants such as chlorine, sediment, volatile organic compounds, bad taste and odours from your water.

On the other hand, Reverse Osmosis Filtration will remove viruses, bacteria, parasites, total dissolved solids, heavy metals, fluoride, herbicides, pesticides, unpleasant odours and any taste.

Reverse Osmosis removes everything but with two challenges:

      • The water becomes acidic (so it needs to be alkalised before consuming).
      • 50-80% of the water goes to waste.

If you feel Reverse Osmosis is the right system for you, please look at our Reverse Osmosis Water Filters collection. If you’re leaning more towards Carbon Filters, please look at our range of Benchtop or Undersink Water Filters.

We have what you need.
