Water that is higher in ionic minerals, maintaining the pH at 7.5-8 and are good for our bodies, we refer to as alkaline water. Also referred to as ‘buffered’.

Research has shown that when drinking alkaline water, you can improve your energy levels, reduce risk of cardiovascular disease and enhance your immune system and much, much more.

You can read more about alkaline water and its benefits in this blog post.

The difference between filtered water and purified water is all in the filtering process. Both types of water are subject to filtration.

However, purified water is cleansed and purified through additional means, such as deionization, distillation and reverse osmosis. This extra purification step increases the purity of the water significantly.

Definitely! No longer do you need to spend ridiculous amounts of your hard earned money on bottled water. Not to mention the reduced cost in cleaning up our environment of plastic bottles!

Absolutely! Western Australia & Perth water is high in calcium. Due to our poor rainfall, we are told the dams are supplemented with ground (bore) water.

We have specialized filters that can easily be installed on the main line to remove calcium and scale. These can be found in our bore water filtration. When combined with sediment removal & heavy meatal/ chlorine/bacteria removal filters, you have an amazingly efficient system for your whole house. For more information go to our blog.

Yes! Contact your plumber attending to your new home. Work out with them where the best place to install you Whole House System is. The plumber can then have the pipes ready for installation after you move in. This will save you some money in plumbing fees later on.

In Perth Metropolitan and most of Western Australian towns, we recommend changing the sediment cartridge at least every six months, due to the high sediment in our water. Some require changing every 3-4 months. Other cartridges we generally recommend every 10-12 months. It is a good idea to check the recommendations on each system.

If your water flow slows down or tastes of chlorine, time to change the  cartridges!

There is no need for you to pay us to change your filter’s catridges.

For your canister systems, we provide you with a spanner to easily undo the canister, turning clockwise, replace with new cartridge and do up again.

For the Quick Change UnderSink systems, we show you how to simply remove the cartridges and replace with new ones.

It’s easy! Our Bench Top filters are a fully DIY system – no plumbing required.

In just 5 minutes, you can be enjoying clean, filtered water.

Sure can! We have an exciting range of water filtration products for the adventurer, caravaners & RV enthusiast.
