This NU Aqua 3-Stage Whole House System Replacement Filter Set is a direct replacement for the NU Aqua Whole House Filtration System. These filters are 4.5”x20” and will directly work with most standard whole-house systems. Produced using premium melt-blown polypropylene fiber these filters provided a high capacity for holding dirt and sediment resulting in a 20% longer life than most standard sediment filters.

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.

Package Includes:

• 1x Stage-1 Sediment Filter

• 1x Stage-2 Heavy Metal KDF/GAC

• 1x Stage-3 Carbon Block Filter
