PSI Water Filters

Purchased a twin undersink filter system as well as combined tap from PSI Water filters about a year and a half ago.
When I was researching and asking questions, they were quick to pick up the phone to answer all my questions, and provide really good insight into what I was after, and not pushy at all.

I decided to get our trusted plumber to install the system for me, and when he looked at everything, he asked me about where I got it from, and he bought one the same to put in his daughters house, which, to me, speaks to the quality of the sys...

Been using PSI for years and can't recommend more highly, they're always super helpful over the phone when I've needed help working out which filters I need for two houses - one on mains water and one on rain/ tank water. Their prices are great too some companies charge almost double for the same products!

After a lot of research I decided to buy the under sink reverse osmosis 5 stage filter from psi water. The company is a reputable Australian company and I love their customer service you can get advice over the phone directly and very helpful if you don't know which filter to choose!

Been using the under sink filter for 3 years and water is delicious, se qld gets hot so we drink plenty ,even water. Friendly and prompt service for replacement filters, no reason to look any further.

Had my triple undersink (PSI 332) for over a year. Works brilliant and you can really taste the water quality. Easy to change the cartridges and the replacement cartridges are very affordable.

Check out the new vs old image from the 1 micron polyspun sediment filter.

have being using them for as my main filter supplier for the last ... 5 years. No issues
prices are very competitive and all the hardware is 100% legit, unlike couple of other random ebay purchases that i did earlier on.

very fast shipping and prompt responses to questions

great work guys, thank you

Very good system, easy to install ( even at 76 Y/O ) Removed old system and replaced with new PSI unit and filters.

I wanted to replace an exisiting system and PSI Water filters provide a kit to do it making it super easy. They even label which filters I chose on the filter housing to make it easier to reorder. The staff were great to deal with and the online ordering option I liked for reordering replacement filters.

Bought PSI under-sink 5 stage RO system and the replacement water filters... quality product. Thanks Peter for good service and advice.

Moved into house 6 years ago and found we had a water filter from PSI. I phoned Stephanie who was so professional in telling me the history of what and when previous owners had ordered so I knew immediately what was required. What is ordered arrives quickly with fitting spanner included. Recommended for personal service and top quality filters.

I have been purchasing my filters from PSI for nearly ten years . Great prices and fast dispatch. Like most people I will check competition pricing but they are generally frilly websites with but not Australian based service . PSI prices are comparable or better, so loyalty to PSI wins each time .

Thank you Peter for your excellent service and advice when I needed to replace the four filters installed in a Boss Reverse Osmosis System fitted to my houseboat on Lake Eildon in Victoria. The supplied filters were competitively priced and were delivered by Australia Post in several days. Testing using a TDS meter has confirmed an excellent result with the filters supplied.

Best instructional DIY. All required parts supplied. Informative, honest, straightforward. Real people offering real service. Quality product and a pleasure.

I've been using PSI Water Filters for over ten year, mostly for replacement filters in the twin under sink system they sold me. The descriptions on their web site are good, but if you're really not sure then they're always happy to talk you through what is needed on the phone.
There web portal makes re-ordering really also as you can re-order the same products with one click.

I purchased a '4 Stage Reverse Osmosis System' about 4 years ago. Customer service is always outstanding. I had a lot of questions where Peter was always happy to answer all of them. When I received my product, I had some more questions where it was great to receive a reply within an hour compared to other businesses, you usually have to wait for days. I just made another purchase for replacement filters where customer service is still outstanding.
