A few years old and still putting out water at 018 TDS . New was 006 and my water with out is around 400 TDS without the filter . 

You will get a portable RO unit , 2 house filter housing ( filters are about 1 year old ) , 32 gallon trash can ( only used for water storage ) has a valve on bottom to fill a 5 gallon bucket , wood stand and tubing . 

I used it once every few months for years to fill the storage can
