The HydroCare high level purification systems for the whole house utilize scientifically advanced materials and design. HydroCare systems incorporate multi step processes to address water quality issues brought in to your home via city water.

Citymaxx Revolutionary Three Stage 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.

Improves the taste and smell of the water.

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 media will also remediate Silica, sulfates, chlorides, phosphates, and silicates.

Citymaxx Installation Manual

This company had great customer service. Quick and easy in explanation and ordering the City Maxx. System provides great water quality for both drinking and bathing. Skin and hair smooth and silky. Water doesn’t taste like salt anymore, better than bottled water.
– Phillip

Amazing technology without big bags of salt!
– Chris

I submitted an inquiry on the Citymaxx whole house filter, and received a call from Phil in their sales department. He answered all of my questions without making me feel that I had to purchase a system from them. He emailed me literature on the filter I was interested in after the phone call. Once I decided to purchase the filter, I called the Phil, and submitted an order. Within a few days the filter arrived, and I had it installed. There is a noticeable difference on how my water tastes now. It is definitely worth it!
