Purchased the PSI twin undersink Pura-Tap replacement unit. Fitting was a breeze, unscrewed the old unit fittings, then swapped out the filter and re-screwed the water fittings. Too easy and now I will save myself the hassle of dealing with the other mob's shonky filter replacement program and order and fit filters at my convenience.

The unit works well and I can't tell any difference between the taste of the water with the PSI unit. Also, my research tells me that the filtering done by this unit (with the appropriate filters fitted) is as good, if not better than the Pura-tap version.

Customer service and delivery time was faultless. Good work PSI!

A very reliable and effective water filter system. Many years service to to my home and family. This "Boss" system is a system that give me confidence that it is doing what it is supposed to do and that is give me clean fresh water. It is so easy to change the filters and get operating again.

I have had this product for about 9 years now and I have found it to be an excellent product, their service is the best, and also at very competitive prices. New filter orders are here within a day. The product is of high quality at low prices. Thank you PSI.

I bought my PSI undersink premium twin reverse osmosis unit from PSI more than 10 years ago and was impressed from the start with the friendly, knowledgeable service and the excellent quality and value of the product.
Renewables are supplied promptly and at very reasonable prices for premium quality filters.
Quality, value, performance and service.
