The U.S.A Made Purotwist undersink is compact, has the latest technology available from the states and offers many advantages, over the economy systems. Some examples of this are : 1) Flow regulation through the heads which gives the water more contact time with the filter medias and longer membrane life (up to 5 years) 2) Self sanitizing on replacement of filters 3) Being compact, it fits anywhere and on any angle under your sink. 4) Also the disposable filter housings ensures that they won't crack, split, leak or become brittle over time caused by pressure.This system will remove almost 100% of the fluoride from your water supply with a minimum reduction of 92.5% when membrane has aged..... It is 100% American Made, Is a sturdy solid unit, and by far the best and most up to date Reverse osmosis system on the market... . In all our years of trial and error this is one of the only systems on the market to keep metal readings under 10 ppm (Parts per millon) for more than 3 years even on Adelaide's water! Search no more cause we hit the jackpot on this one. No need for any other bulky and outdated undersink reverse osmosis systems anymore. It's compact, non-corrosive, and does the best job possible, also it comes at the right price. This baby ticks all the boxes
