Whole House Water Filters in Darwin

A complete, point-of-entry, water filtration system for the home; installed for free across Darwin and Victoria

Numerous Darwin residents settle on a Whole of House water filter. Our system is comprehensive and even features anti-scale technology which protects your appliances!

Above all, it shields your friends and family from ingesting risky water loaded with synthetic compounds.

Chlorine is one of those chemicals. Did you realize that more chlorine winds up in the body from a short (5-minute) shower than you get from drinking eight glasses of water?

Chlorine reacts with hair protein, making hair dry and inclined to break. It does the same to the skin!

Over time, this leads to premature aging! It can also irritate the skin and make any existing skin conditions worse.

Learn more about the process of whole house filtration, and signs you need to install a system at your property.

This point-of-entry water filter can improve your Darwin home’s water dramatically. Choose from UV purifying, carbon filtration, water softening, and others. They’re all installed for free, throughout Darwin.

Every Whole-House water filtration system we install comes with a FREE Vortex water softening machine. We know that some households source their raw water from water tanks, but this puts them at risk of ingesting heavy metals.

The Vortex is valued at $500 and completely gets rid of any heavy metal residue in your water, keeping you and your family safe from contaminated water.

When you invest in one of our systems, it comes with 10 years of free customer support. Free installation and the option of using one of our interest-free payment plans means you end up saving money.

RO / Reverse Osmosis Water Filters Darwin

Is your Darwin water supply not up to scratch? We install many under-counter Reverse Osmosis water filters in the Darwin region.

Close to 90% of Darwin’s water supply comes from the Darwin River Dam, south of the town. The remaining percentage is sourced from two bore fields southeast of Darwin.

Although water is treated before reaching the home, there’s always a chance of contamination by bacteria, algae, and of course, chemicals that are added in the treatment process.

The process of reverse osmosis is an innovative and very comprehensive way to purify water. The Elite Series 3 is the best-selling product we make.

Worried about impurities in your drinking water? A reverse osmosis water filter might be your solution.

With our RO water filter, your water will be purified in four extensive phases. These phases completely eliminate pesticides & herbicides, bacteria, dirt, rust, and even hazardous chemicals like chlorine and fluoride.

If you’d like to improve your water’s hardness, the Elite Series 3 also removes heavy metals, microplastics, and microfibres from your raw water supply.

This compact, professional RO water filter is fitted right underneath the sink in your kitchen. It’s undoubtedly the most efficient under-sink water filter you can buy, providing you with odour-free, clean-tasting drinking water in Darwin.

This reverse osmosis filtration technology ensures that nobody has to drink unsanitary, impure tap water! Instead, everyone can have access to pure, uncontaminated water.

Alkaline Water Filters Darwin

The best Alkaline water filters and purifiers to install at home!

Science researchers have discovered that those who drink alkaline water with a pH of 8.8 of thereabouts don’t suffer much from acid reflux. It was further found that alkaline water deactivates pepsin, the enzyme that causes acid reflux.

Our Elite Series 2 filtration system is an alkaline water filter that both removes contaminants and adds minerals to your water supply.

This is the best option for clients searching for a customisable filter. A portion of our clients wish to remove the fluoride from their water. Others wish to keep it in. Our cartridges can do everything.

Some key benefits of drinking alkaline water:

  • Super-hydrating. Alkaline water features smaller molecular content making it far easier for the body to absorb
  • Detoxes the body by washing away toxins that may play a role in developing diseases and illnesses
  • Balances pH levels by neutralising acid. When your body becomes too acidic, it can disrupt cell activity
  • Powerful antioxidant; protecting your body from free radicals can potentially cause a variety of health problems
  • Boosts the immune system; a natural effect of neutralising free radicals, in turn, and helping to cleanse and remove toxins

It’s a flexible, super purification system that makes your drinking water rich in goodness with the perfect pH7+ balance.
