What Do Water Filters Remove?

| By

If you’re considering installing a water filtration system for your home, you might be wondering what water filters actually remove and how they benefit you. Well, don’t worry—we’re here to tell you!

Here in Australia, our treatment plants do their best to kill any dangerous microbes and toxins from the water supply. They do this by adding safe levels of chemical disinfectants like chlorine and chloramine. These chemicals help remove bacteria and waterborne viruses, but they don’t remove all contaminants—and they don’t taste great or bring major health benefits either. As a result, there are plenty of contaminants that enter your home’s water system, creating bad-tasting water, causing nasty irritants, and damaging appliances.

Let’s look at chlorine and chloramine in more detail, along with the other contaminants a home filtration system can remove.

Common Home Water Contaminants

Chlorine and Chloramine

We’ll start with the big one. Chlorine has been used to sanitise our water supplies here in Australia for decades. However, we now know that in addition to having a low residual life, chlorine also produces carcinogenic by-products like trihalomethanes (THMs). In response, local water authorities are opting to use chloramines (chlorine with added ammonia to make it last longer) instead as their primary disinfectant. However, these chemicals linger in the water supply, are terrible for local marine life, and are hard to remove without the use of specialist home water filtration systems.

State-of-the-art systems, however, like our Complete Home Filtration system, can remove up to 98.5% of chlorine and other chlorine by-products—offering great-tasting, healthier water for you and your family.


Fluoride is another chemical that finds its way into our water supplies, both naturally—as a result of runoff from weathering of fluoride-containing rocks and soils—and intentionally by local water authorities.

Controlled levels of fluoride help to reduce tooth decay, but too much fluoride can have an adverse effect. Some reports suggest too much fluoride intake can cause serious health issues, including neurological problems, high blood pressure and skeletal weakness. The most effective way to remove fluoride from your home’s water supply is with a Reverse Osmosis water filtration system, which can reduce fluoride levels by more than 90%.


PFA’s are a major issue that affect the whole world. Invented in the 1950’s by Du Pont and manufactured by 3M, Per- and Poly-Fluoroalkyl Substances (PFA’s) contaminate 95% of the world’s water supplies.

Found in Teflon non-stick pans, Scotch Guard and Aqueous Film Forming Foam, these ‘Forever Chemicals’ do not break down and can travel for long distances through water and air. Over time, they build up in people and animals, causing serious health issues—like infertility, thyroid disease, suppressed immune functions, and even cancer—while destroying natural ecosystems.

While Activated Carbon and Reverse Osmosis systems significantly reduce PFAS, no one has developed a water filter that can reduce PFA’s to a healthy, consumable level… Until now! Complete Home Filtration is currently in the final stages of developing and launching a world-first, proprietary filtration system that removes 100% of PFA compounds from contaminated bore water. 

Hard Water

If you live in an area with hard water, your home is more susceptible to limescale, which is caused by calcium molecules. Limescale builds up in pipes, faucets and appliances like dishwashers, washing machines, kettles and coffee makers—causing performance loss and breakdowns. Hard water can also cause dry skin and hair, while being harsh on clothing and fabrics. 

To remove hardness from your water, you would traditionally need a water softener, which filters out calcium and magnesium in exchange for sodium ions. However, these can also be harmful to human health and the environment. Here at Complete Home Filtration, we’re proud to offer the healthiest and most effective way to prevent limescale. Our revolutionary SP3 scale prevention system retains magnesium minerals and calcium—both of which are essential for our nervous system and muscle function—but without all the nasty, scaly side effects.

Heavy metals

Hard water also brings another issue, in that it also likely contains heavy metal elements like manganese, lead, arsenic, chromium and copper. While small amounts of some of these are essential for healthy biochemical function, metals such as lead, chromium and arsenic can be toxic when ingested. Fortunately, an advanced water filtration system can deliver clean water filtered to 1 micron, reliably removing a range of heavy metals.

Sand, Silt, and Sediment

Water treatment facilities do a pretty good job of removing dirt, silt, and sand from your water supply, but some smaller particles still make their way through. That’s why we designed our Complete Home Filtration system with three filter stages, removing even the finest sediment particles, dirt, and chemicals from your tap water. 

Why Install a Complete Home Filtration System

Our Complete Home Filtration System is designed to improve your health and wellbeing while saving you money and cutting down your plastic use.

Once plumbed into your home, all raw tap water passes through four stages of filtration, delivering clean, fresh water to all of your home’s water outlets. As an added bonus, you’ll help protect the planet by reducing the number of plastic bottles in landfills, while reaping the benefits of having less chlorine in your shower water—offering softer, less dry skin and hair—and reduced calcium build-up on shower screens, fixtures, and appliances to save you money in the long run.
