Water filters have become increasingly popular in kitchens, offices and even fridge systems around Australia. By getting rid of contaminants in the natural water supply, water filters ensure the cleanest drinking water possible for the whole house, making a great addition to any home.


But why stop at the kitchen tap? After all water is much more than just a drink: from showering, brushing our teeth, washing our hands, cooking, doing the dishes or the laundry, to watering our gardens, this liquid is an essential part of life. Given how many other ways we come into contact with water every day, filtered drinking water is really only a start.

Why install whole house water filtration systems?

Although Australia’s water quality is highly regarded, there is no such thing as naturally pure water. Sydney’s water supply is regularly tested for 70 different impurities – ranging from microorganisms and chemicals to strange taste, odour and colour. But water quality can vary due to rainfall and flooding, Sydney Water’s operations and, occasionally, other incidents, faults or emergencies that crop up.


Water filtration systems for the entire house are the safest bet for purifying your water at the point of entry, rather than the point of use. By eliminating potential contaminants in the main water line of your home, they safeguard the water supply throughout your home rather than just in the kitchen.


Health benefits, financial savings and longer-lasting appliances are just some of the advantages of installing a whole house water filtration system in your home.


Cleaner showers

Many people don’t realise that our mouths aren’t the only consumers of water. When showering, water is absorbed into our bodies through our pores, any damaged skin like scratches or wounds, and the inhalation of steam. This is particularly true for children, who have an increased rate of dermal or skin absorption.


In fact, one study suggested that when it comes to some chemical by-products such as trihalomethanes, the rate we absorb them from inhalation while showering or cooking with water is comparable to when we drink them directly in water!


Less chemicals

Pesticides, herbicides, nitrate, aluminium, lead and other metals are just some of the nasties that may lurk in the water supply.

Lessening our exposure to chemicals is important to consider for not only our drinking water but also for day-to-day chores like washing our clothes, dishes and cutlery. The effects of too many chemical contaminants can be seen in stained clothes, for instance, as well as soap scum remaining on dishes after you’ve washed up.


By filtering out the chemicals, a whole house water filtration system won’t just improve the safety and quality of your home’s water supply, but also the air quality in your home.


Better for your appliances – and wallet

The ‘hard water’ caused by a high concentration of minerals like magnesium and calcium can lead to a build-of up deposit in your pipes, shower heads, water heaters and other appliances. This can cause scales to form in your toilet, shower or bathtub, as well as stained water fixtures in your bathroom or kitchen.


Having cleaner water in your household’s pipes and appliances leads to a cleaner house overall. It can also give your appliances an extended life. Increasing the lifespan of your water fixtures, appliances, and even clothes, dishes and other commonly washed items is a win for your wallet as well as your household’s health.

Good for the environment

By providing an estimated 3,000 litres of water per year, the average water filter dramatically reduces the need for plastic bottles of water, which are a scourge for our environment, clogging dumping grounds and oceans alike.

Understanding the Importance of Water Filtration

Water is an essential component for health and life. Be it for cooking, drinking or cleaning, accessing safe and clean water is essential.
