Great Value Review by Cowboy
Whole house reverse osmosis system that uses two carbon-blok filters and a 5micron sediment filter. High TDS water and high clorine community water system. Filters have to be changed 4 times a year so cost and ease of use are important. (Posted on 5/16/13)
ease of ordering and installation Review by Bob
Filters arrived sooner than I had expected and was pleasantly surprised that they installed easily on the two filter
system of our schools ice machine. Great product
