Whole-home water treatment and filtration cost factors:

Type of system

Different water filtration systems filter out chemicals/toxins from your home's water. And, of course, the type of system you choose will dictate your price.

Our licensed plumbers will analyze your home's water and determine which system best suits your needs. We carry water treatment systems from top brands that can filter any contaminant.

Ongoing maintenance costs

Some systems require regular filter changes, while others are maintenance-free and typically more expensive.

The good news is that the Cooper Green Team offers various maintenance plans tailored to your system and desired service frequency.

System size

The larger the system, the more expensive it will be in terms of the actual system cost and the labor required to install it. We can help you determine the size of your water treatment system based on your family's water needs.

Looking for an exact installation estimate?

We can help. We offer free, in-home water filtration installation estimates—sometimes as soon as the day you call. Our plumbers are trained to help identify the chemicals in your water and the system that will help filter them out.
