Why Choose a reverse osmosis water filter system?
A reverse osmosis system is the most effective way to ensure your family has pure, great-tasting drinking water. In New Zealand, homes from Auckland mains to Warkworth tank or bore supply can contain chlorine, fluoride, nitrates, heavy metals, and more. RO removes up to 99% of these contaminants, delivering crisp, safe water straight from your tap.
It is the ONLY filtration method proven to remove arsenic, boron, salts, fluoride, nano-microplastics and PFAS, delivering unmatched purity, safety and long-term reassurance.
How Reverse Osmosis Filtration Works
Reverse Osmosis (RO) is a sophisticated water purification technology that uses pressure to push water through a semi-permeable membrane, removing unwanted contaminants, dissolved salts and impurities.
The magic of RO lies in its multi-stage filtration process. Each stage targets specific pollutants, delivering cleaner, fresher water at every step. Aqua Works offers 3- to 6-stage systems, with each additional stage providing deeper, more comprehensive protection. Find out more…

FAQ about UV Water Filters
What does an RO system remove?
Fluoride: Nowadays, commonly added to public water supplies.
Salt and excess minerals: Important for those on low-sodium diets.
Sediments: Dirt, sand, and other large particles.
Chlorine: Water disinfection can leave unpleasant taste and odour.
Arsenic: A dangerous contaminant often found in groundwater.
Volatile Organic Compounds (VOCs): Chemicals that can leach into the water from pesticides and industrial waste.
Microplastics: Tiny plastic particles, increasingly found in water supplies.
Herbicides & Pesticides: Harmful agricultural runoff can end up in water supplies.
Heavy Metals: Such as lead, mercury, and cadmium, which can be harmful to human health.
What are alternatives to Reverse Osmosis
UV Water Filtration: UV filters are an excellent addition to any RO system. They kill bacteria and viruses that may slip through conventional filtration methods, like E.Coli, Giardia & Campylobacter.
Whole House Water Filters: These systems purify water at every tap, targeting contaminants like sediment, chlorine, and heavy metals. While less thorough than RO, they provide good overall protection.
Bottled Water: Though convenient, bottled water can be expensive and environmentally harmful due to plastic waste.
Carbon Filter: Herbicide, pesticides and VOCs will be effectively removed with this type of filter.
For arsenic, boron, salts & minerals, fluoride, nano microplastics and FPAS, Reveres Osmosis is the only filtration system that effectively removes these unwanted substances.
What are potential disadvantages of RO
Water Wastage: For every gallon of filtered water produced, an RO system can waste 3 to 4 gallons of water. However, modern water-saving models can mitigate this.
Removes healthy minerals: RO systems strip out beneficial minerals like calcium and magnesium. Additionally, it decreases the pH of your water. However, Aqua Works’ remineralisation filters can reintroduce these nutrients, ensuring balanced water.
Regular maintenance required: To keep your RO system performing at its best, periodic filter changes and professional servicing are required. Aqua Works offers maintenance services to ensure everything runs smoothly.
Does reverse osmosis waste water?
???
Does reverse osmosis remove healthy minerals?
Yes, it removes some minerals and contaminants, but your daily nutrition mainly comes from food. Aqua Works can adds a remineralisation stage so you keep great-tasting, pH-balanced water in your New Zealand home.
How often should I change RO filters?
In New Zealand homes, pre-filters are changed every 6–12 months and membranes every 3–5 years. Aqua Works offers local servicing around Warkworth and Auckland to keep your system performing perfectly year-round.
Can I use a reverse osmosis system with tank or bore water?
Yes. Aqua Works designs systems for Auckland and Warkworth homes on rain-tank or bore supply. We test your water first and include the right pre-filtration or booster pump to ensure consistent pressure and purity.
Will a Reverse Osmosis system improve taste and odour?
Absolutely. Reverse osmosis removes chlorine, sediment and dissolved minerals that cause metallic or chemical taste. Warkworth and Auckland customers notice a clear, fresh flavour immediately after installation.
