The service was great and our water problems were resolved. We appreciated the time put into testing the water and discovering what we thought to be true - there was iron/rust in the water, and it was also verified it came from the city water. Although we will now pay more for a new system, we...believe it is well worth it. We are 100 percent satisfied.read more

"Hey Bill & Chris! Regarding our service call yesterday, our overall experience was awesome. A personal call for service, with a technician arriving quickly! Nick was very friendly, thorough and professional. Very quick with his diagnostics and repair. And, very reasonably priced! Every experience we’ve had with the Certain folks has been incredible, but each time you seem to go above and beyond the last. And, most importantly… perfect water!! Thank-you!" - Steve Donaldson

Frequently Asked Whole House Water Filter System Questions:

What is the best whole house water filter?

We might be biased, but we believe the best whole house water filter for your home is a Certain Services, Inc. Water Filter. Our filters:

  • Are WQA certified, IAPMO certified, and NSF/ANSI Standard 44 certified.
  • Address water quality issues such as iron, sediment, acidity, taste, and odor.
  • Reduce Chlorine, Chloramines or particulates.
  • Neutralize corrosiveness to protect fixtures, pipes, and appliances.
  • Employ natural oxidation to remove iron & manganese.

How much does a home water filtration system cost?

A home water filtration system costs between $900 and $3,000. They are designed to be easy to install and remove (good news if you want to take your unit with you when you move). However, unless you are confident in your electrical and plumbing abilities, you might want to hire a plumber which could add $100 to $600 to the initial cost of your unit. Purchasing a water softener through a water filtration system installation company can save you money on installation costs. Contact us today for a free quote.
