Stage 1

The Polyphosphate filter prevents the formation of scale and corrosion. It also reduces silt, rust, dirt, sediment, existing scale & sand. Unlike a water softener, this focuses on disrupting the formation of scale.

Stage 2

The Kinetic Degradation Fluxion filter captures Iron, Lead, Chloramine, Sulfur, Algae, Hydrogen Sulfide, Mercury, Chlorine & Aluminum. This stage is focused on capturing heavy metal contaminants.

Stage 3

The Activated Carbon Block filter captures Chlorine, Total Organic Carbon (TOC), Pharmaceuticals, Turbidity, and Chemicals causing bad tastes and odors. This stage focuses on taste and drinkability of your water and filtering chemicals.

one of the best decisions I made for my family!

Since the install, we have noticed a significant change in the water quality of our home. Living in Arizona is already tough with the dry weather and hot temps, and the regular tap water did not help with our skin as it was always getting dry no matter how much lotion we used. After the unit was installed, our skin no longer has that extremely dry feeling and since we also have the RO system with UV and Alkaline system, the drinking water even tastes nicer. Overall we are happy with this purchase!

Replaced our water softener

The customer service has been excellent any time we have had to contact the company. We’ve had our reverse osmosis system for several years and it has been excellent. So when our water softener quit and needed repair, I started looking at other options. We decided on the whole home ultimate protection. It’s only been in use a short time but is working well. I was concerned we wouldn’t notice a difference but we get suds in the shower and the water feels better. Our skin feels better. This was a great option for us. I wish they would have released the salt free softener three weeks earlier tho. I won’t miss the expense of bags of salt or carrying them to the basement. Background- we live in a rural area with well water. Our water is extremely hard. Without a softener or conditioner our appliances and water heater scale up quickly. Our skin dries out and we get itchy.
