Why Filtering Your Drinking Water Is Not Enough?


Tap Water Contaminants


CityMaxx Three State Filtration Process:

Stage 1

Incorporates a 25 to 1 micron pre-filter removes sediment, insoluble iron and microorganisms such as cysts. It extends life of other filters.

Stage 2

Unique Carbon block with patented Nanotechnology removes and reduces impurities such as chlorine, cysts, chemicals, insoluble lead and mercury, parasites, THMs, VOCs, and much more. The carbon block goes down to .5 micron without pressure loss. It removes parasites as no known parasite smaller than 1 micron.

Stage 3

Complete Scale prevention and removal in all pipes and heat exchangers. Through the scientific process of Nucleation Assisted Crystallization (NAC), the catalytic media transforms the calcium and magnesium minerals into harmless, Nano-sized crystal particles. The crystals remain suspended and do not adhere to pipes or heating elements. They also dissolve preexisting scale deposits.

The CityMaxx is unlike any other system on the market. It is a large capacity purification system for the whole house PLUS green technology for the removal of existing and prevention for future limescale buildup for homes on city water.
