Reverse Osmosis Water Filter Systems
Reverse Osmosis Water Filter Systems

Reverse osmosis water filters are becoming increasingly popular in Australia. They're a great way to purify water and make it safe for consumption. If you're looking to equip your home with an advanced reverse osmosis water filter, look no further than PSI.

PSI is the number one supplier for all reverse osmosis water filters in Australia. We have everything from laundry style and under-sink to countertop and commercial high-volume reverse osmosis water filters.

How does a reverse osmosis water filter work?

Reverse osmosis water filters use tremendous pressure to force water through a membrane which blocks harmful contaminants like lead, mercury,fluoride, arsenic, chlorine, pesticides, herbicides and other chemicals from getting into your drinking water. The result is clean, clear water that tastes great!
