Not the best unit to buy. It has a 90-94% waste profile; ideally you want a unit that can do 98% and it produces small quantities of R/O water. Plus you still will need to dechlorinate the water which kind of defeats the whole point of the unit.
If your tap water is fine in New Jersey then stick with that because that R/O unit is not doing much too the water. There are much better things to spend the money on. Have you got the test kits yet??
