Save money on water

The cost of plastic bottles adds up very quickly for both our wallet and the environment. Interestingly, the water in many plastic bottles is simply industrial filtered tap water. All Waranu Water filters skip the middle man by giving you exceptionally purified water while helping you reduce your environmental impact.

Click on the tabs to your right, to compare the average cost per glass (600ml) of filtered water for each of our water filtration systems.

If you or someone from home purchased only 1 bottle (600ml) per day for an entire year at an average cost of $2.50 you end up paying… $912.50 (90% of that is the actual cost of the plastic bottle)
Not only would you be reducing your environmental impact.. but you would make your money back in the 1st year if you were to substitute your plastic bottle consumption using a Proteus RO.

I decided to finally buy a Proteus RO for my family. Realised in the end how much money I’d save from not buying plastic bottles for the entire household, let alone the environmental impact we’d have.
