kwik-twist.pngAbout KwikTwist™

At Purestream Water Filters we pride ourselves on acknowledging needs in the market place and then looking to meet those needs.

Over the years I regularly have people on the phone requiring assistance with undoing housings to change cartridges, whether it be undersink, portable units or shower filters. Plus we have time poor customers who once a year struggle to remember what to do and with the cost of trades people these days, making the yearly exchange simple has been Purestream's goal.

We also have an ageing population and with this in mind over the past 12 months I have aggressively searched for an innovative range of water filters that are easy DYI whilst maintaining the highest quality backed by a 10 Year Warranty.

Whilst there are easy change (bayonet) systems currently available these are expensive ranging upwards of $700 with expensive replacement cartridges. Purestream fully appreciates that the yearly ongoing costs are even more important than the initial cost and when standard housing cartridges are half the price of bayonet style, Purestream has not, until now, entered the easy change market.

Purestream is very proud to introduce the KwikTwist™ range manufactured by a world leader in engineering and water purification.
