This NU Aqua Granular Activated Carbon Filter or GAC filter is a direct replacement for the NU Aqua Whole House Water Filtration System. This filter is 4.5” x 20” and will directly work with most standard whole home systems. Manufactured using HydraCoil technology these filters provide a higher absorption rate due to the molecular structure of the pores becoming more permeable which allows even the smallest of particles to be efficiently removed from your water. With a ten times chlorine absorption capacity these filters are the premier carbon block filter on the market.
I like the company and product. My main criticism is the lack of customer service. I needed the part number for the replacement elements, and they never responded. Until I guessed and ordered the wrong ones. Then I had to return them and start over. Still like the product, however.
