Undersink Reverse Osmosis Water Filter Systems

PSI water filters are the number one Australian supplier for all reverse osmosis filtration systems and purifiers. Our range varies from laundry style, under sink, and countertop to the commercial high volume reverse osmosis systems.

Each water filter system available uses one of two housing materials, typically QMP American made housings in our premium range and quality Taiwan made housings in our standard range.

All housings used in our reverse osmosis water filters are Watermarked and meet Australian standards.

All under sink systems come with a mains connection kit including a pressure limiting valve, storage tank in various sizes, dedicated filtered water tap and setup instructions to ensure effective water purification.

We stock all the replacement filters, including membranes, water filter cartridges, and many after-market and non-standard filters & fittings.
