Reverse Osmosis is a process where water is demineralised using a semi-permeable membrane at high pressure. Your normal filtration units will only reduce certain contaminants such as silt, rust, chlorine and bacteria (up to 96%). Your reverse osmosis unit will purify your water up to 99.9% or 0.0001 microns, thus removing other dissolved contaminants such as colloid, lead, mercury, germs and other metals.
It is essential that you maintain your home reverse osmosis unit to ensure you produce only the cleanest water and that you do not “poison” your drinking water. This is an example of how your filters look when they are not properly maintained. The difference between the new and used filters is evident and tells its own story. When the filter is not changed regularly, contaminants build up in the filter, it slows the flow of the water and most importantly, it feeds all the contaminants back into your drinking water!
Depending on the source of the incoming water we recommend the following as a minimum requirement:
Stage 1 - Polypropylene Cartridge – Compacted Fibre Filter
Removes particles such as silt and rust
Stage 2 - Activated Carbon Filter
Removes chlorine and odours
Stage 3 – Granular Active Carbon
Removes additional chlorine and water discolourants
Stage 4 – Reverse Osmosis Filter
Removes colloid, heavy metals, dissolvable solids, germs, bacteria and other harmful substances up to 1 micron
Stage 5 - Post Activated Carbon Filter
Removes any additional odours
Stage 6/7 – Re-mineralization Filter
Optional but recommended.
Choice of one or both of the following:
Re-mineralization Filter – Re-introduces certain minerals Alkaline filter – Produces water with pH 8 and higher
