Pentair Product Cost Ranges

The costs for Pentair products range widely because of the many types of filtration methods and technologies the company offers. Here are the typical cost ranges for the company’s products at the time of publication.

Pentair Product Costs
Pentair Product TypeAverage Cost
Whole-House Multiple Stage Filtration$1,600
Whole-House UV Filtration$800
Whole-House Sediment Filtration$160
Whole-House Carbon Filtration$900
Undersink Filtration$300
Undersink Reverse Osmosis Filtration$500
Replacement Filters or Cartridges$100 to $300
Water Softener System$1,000 to $3,000

If you plan to have your water filtration professionally installed, labor costs will add $100 to $500 on average. Expect to pay more for larger or more complex systems, or for projects requiring additional plumbing work prior to installation.

What Factors Affect Pentair Costs?

Because of the variance of each water filtration system, there are several factors that influence the cost and installation of Pentair products.

  • Whole-House vs. Point-of-Use Systems: How much water you want to treat is the biggest factor in your overall cost. Point-of-entry or whole-house systems that connect to your home’s main water line are more expensive than an undersink or faucet water filter system.
  • System Size: If you decide on a whole-house filtration system, its size will also determine your cost. Pentair’s water filtration buying guide segments their systems by a home’s number of bathrooms. Systems that accommodate up to three bathrooms typically cost less than those for homes between four and six bathrooms.
  • Multiple Filtration Stages: Also for whole-house systems, the more stages needed to treat your home’s water, the more expensive the system. For example, a single UV filtration stage will cost less than a system requiring a sediment pre-filter, UV treatment, and a carbon filter.
  • Professional Installation vs. DIY: Pentair indicates most of its products are DIY friendly and can potentially save you hundreds of dollars in installation costs. Pay attention to the company’s warranty policies, however, as they typically do not cover improper installation and the use of non-Pentair replacement parts.
  • Regular Maintenance: While this will not affect your initial upfront investment, consider your long-term costs covering the life of the product. Most whole-house and undersink water filtration systems require some regular maintenance. Factor in costs for replacement filters or cartridges, along with any professional inspections for whole-house systems.

Benefits of Investing in a Pentair System

Pentair is a recognized industry leader in water supply and treatment for homes, pools, and commercial applications. The company can be a single source for your home’s water treatment requirements.

How Pentair Compares to the Competition

Here’s how the company stacks up against a few of its primary competitors.

Pentair vs. Culligan

Culligan is a national provider of water treatment solutions and dispensing. (Remember the Culligan Man ads?) The company offers whole-house water filtration, undersink and reverse osmosis filtration, and water softeners. Culligan features similar filtration options and includes a few more Pentair does not offer. The company requires an in-home consultation for customized system pricing; however it comes with complimentary water testing. Culligan contractors are also employed by the company and are not independent contractors. Many of Culligan’s products are available through online retailers and are backed by a limited lifetime warranty.

Pentair vs. Aquasana

Aquasana offers single- and multi-stage whole-house water filtration systems to treat municipal or well water. Its point-of-use product selection is more robust than Pentair’s and includes undersink, countertop, and shower water filters. Homeowners can purchase Aquasana products directly from the company’s website, from retailers, or through its independent contractor network. Aquasana does not offer water testing services. Product warranties range from one to two years for point-of-use products and from two to 10 years for whole-house filtration systems.

Pentair vs. Kinetico

Similar to Pentair, Kinetico offers whole-house filtration, drinking water filtration, and water softener systems. In its whole-house systems, the company features similar add-on products to target specific water conditions. Its drinking water filtration is limited to its countertop reverse osmosis model with no undersink options available. Some Kinetico products can be purchased through online retailers, however the company recommends an in-home consultations with a screened independent contractor. Complimentary water testing is available during this appointment. Product warranty coverage ranges from five to 10 years depending on the filtration or softening product.
