What drinking water supply are people drinking in 


Town Water?

Without treatment, this municipal water supply contains chemicals that can have an adverse affect upon your health.

If your water comes from the popular town water dams, then we suggest our Alkaline Water Filter, or Reverse Osmosis Water Filter, or Whole House Water Filter.


Tank Water?

Another popular source of water in rainwater tanks, which allows the collection of natural rainfall. When consuming this type of water supply, you risk the contamination of bacteria and parasites which has not been filtered out.

If you have sourced your drinking water from water tanks, then our Alkaline Water Filter, or Whole House Water Filter will be most beneficial to you.


Bore Water?

Instead, some areas may choose to source their water through water bores. This underground water requires softening and purification before drinking.

If you drink underground bore water, then opt for our Reverse Osmosis Water Filter or Whole House Water Filter to ensure you are drinking clean, healthy water.
