How Much Does It Cost To Install a Whole-House Water Filter in Phoenix?

May 12, 2021

A whole-house water filter works by treating water where the main line enters your home and delivering filtered water to all your taps and appliances. If you’d like to have one installed, the price can vary quite a bit.

The cost of a whole-house water filter installation in Phoenix ranges from $1000-$5500, with the average cost being about $2,850.

How much you pay for installation will depend on the following factors:

  1. The type of water filtration you need
  2. The existing plumbing in your home
  3. The plumber you choose for installation

Below, we’ll provide more details about each of these factors to help you make a decision that fits your home, lifestyle and budget.


We go above and beyond to provide a water filtration solution that suits your family’s needs. Get more details about water filter installation in Phoenix or schedule your free estimate today.


Cost factor #1: The type of water filtration you need

The type of water filter you need will depend on what contaminants are in your water.

To determine what kind of water filter you need for your Phoenix home, follow this three-step process:

Find out what is in your water. A great way to start is by getting a copy of your water quality report (called a Consumer Confidence Report or CCR).

Determine which contaminants you’d like to treat. Since not all water filters can reduce all contaminants, the results of your water test will influence what type of filter you choose. Other factors like your water’s taste and appearance may also affect your decision. You’ll want to review your water quality report closely to determine which contaminants you need to reduce. Once you know what is in your water, you can decide how you’d like to improve its quality and what kind of water filtration system will best address your concerns.

Research different water filter options. There are several different types of water filtration solutions, including whole-house systems (also called point-of-entry or POE systems). The price of your whole-house system will depend on the type you need, such as:

  • A carbon filter ($800 to $4,500): Carbon filters reduce chlorine levels in your home’s water. They also help treat water with bad tastes or odors. They work by using small pieces of carbon to absorb contaminants.
  • A reverse osmosis system ($1,000 to $4,000): Reverse osmosis systems (also called R.O. systems) reduce high levels of arsenic, iron, and nitrate in your water. They work by pressurizing the water and forcing it through multiple filters to eliminate contaminants.
  • A water softener ($1,000 to $4,500): Although a water softener will not filter your water, it will reduce hard water in your home. Hard water contains high levels of calcium and magnesium carbonates, which can cause sediment buildup in your home’s pipes and plumbing fixtures. Water softeners reduce hard water by using salt and ion-exchange resins to remove minerals. There are many different types of water softeners, so the price range varies.

Annual maintenance for a whole-house water filter can also cost $50 to $300 depending on the number of filtration stages it has, the types of filters it uses, and if you choose to maintain it yourself or hire a plumber for ongoing maintenance.

If you find that a whole-house water filter is outside your ideal budget, you may want to consider a point-of-use water filtration system instead.

  • Unlike POE systems, which filter water before it enters the home, point-of-use water filtration systems are installed on appliances and faucets themselves.
  • Point-of-use systems are cheaper than POE systems, but if you’re considering a water filter for several different appliances in your home, a whole-house water filter may be worth the extra cost.

If you’re unsure about which type of water filter is best for your home and budget, a plumber can help you by providing professional recommendations based on your water filtration needs.

Cost factor #2: The existing plumbing in your home

A plumber may need to add to or modify your home’s plumbing to install a whole-house water filter system, which will increase the cost.

In an ideal situation, your home’s plumbing won’t require any changes to install a whole-house water filter. However, that’s not always the case.

Installing a water filtration system can be a complex process and modifying or adding to your home’s existing plumbing will require extra labor, materials and time. As a result, you may end up paying $1,000 to $2,000 more to complete the project.

Cost factor #3: The plumber you choose for installation

Although it might be tempting to cut costs and go with a Phoenix plumber that charges less for the job, a higher price tag often means better quality installation and a more experienced plumber. This will save you money down the road by avoiding poor-quality installation.

To choose a high-quality plumber for water filter installation, make sure the company meets the following criteria:

Has positive online reviews from customers (check Facebook, Google, Yelp, etc.)
