Undersink Reverse Osmosis Water Filter Systems

If you are super health-conscious and want only the finest quality filtered drinking water in your home, then Reverse Osmosis is for you! In addition to improving the taste/odour of your water, and removing chemicals (such as Chlorine, Disinfection By-Products such as Chlorate, Chlorite, Bromate, Trihalomethanes, and Haloacetic Acids, as well as Pesticides and Herbicides), Reverse Osmosis filtration also offers a 98% average reduction of Fluoride and Heavy Metals. Simply put, Reverse Osmosis is the most effective, consistent, and cost-efficient means of filtering out Fluoride and Heavy Metals in domestic drinking water!

As well as reducing the maximum amount of contaminants, our Reverse Osmosis filters for drinking water also use Coconut Carbon and/or Natural Mineral Media to buffer the pH level from neutral, to alkaline, and even high alkaline!

• If you want High Alkaline Water, opt for The Original 7 Stage High Alkaline Undersink RO System, which uses Magnesium and Potassium electrolyte minerals followed by Coconut Carbon to generate a strong alkaline pH ranging from 8.5-10.
• If you just want Alkaline water with a pH of 8-9.5, we recommend the 5 Stage Alkaline Undersink RO System which uses Magnesium and Coconut Carbon.
• If you don't want any minerals in your water (i.e. for brewing), consider the 4 Stage Undersink RO System with Carbon Post-Filter (which is optionally removable).
• Otherwise, all of our other under-sink RO filters use Calcium followed by Coconut Carbon to produce pH-neutral water that averages out to a range of 7-8 (note: the Carbon Post Filter is likely to spike the pH significantly to above this range when first installed and should average out quickly). 

If you have never had RO filtration before, please note that all systems come with a Water Storage Tank and Faucet Tap as standard, and if you have a fridge water dispenser and ice-maker, you can even tee off from the filter system to your fridge to get cold filtered water and ice on tap!

Please note that Reverse Osmosis filtration works optimally on Chlorinated Mains/Municipal/Town water, although in some rare cases, Reverse Osmosis may be suitable for treating Bore Water that has been comprehensively tested, analyzed, and deemed suitable for RO Treatment by our in-house water treatment expert. In this case, we would normally recommend the High Performance Smart Monitor RO System, which features a booster pump to ensure the system has sufficient osmotic pressure to ensure consistent contaminant reduction results when working alongside a standard household accumulator pump.
