The Best Water Filtration Systems for Homes
Every homeowner knows that clean water is vital for a healthy household. However, many are shocked that tap water often contains hidden contaminants. Alarmingly, harmful elements, like lead or chlorine, can lurk in your water, unbeknownst to you.

Based in Sterling, VA, we proudly offer top-quality water filtration systems in the area, including Alexandria, Gainesville, and Herndon, to ensure that you get pure, clean water every time you turn on your faucet.
How Much Does Water Filtration Cost?
Water filtration typically costs between $800 and $7,000. The final price depends on the type of filtration system, the size of the home and whether the system is designed for a single fixture or the entire house. Whole-home systems and more advanced filtration options will generally cost more than point-of-use systems.

Great Experience

Knowledge, Professionalism & Dedication
“Miguel, HVAC technician from Cardinal Plumbing Heating & Air, came to my home to inspect the HVAC system and vents. I had recently bought the house and had no prior HVAC history, so I wanted to ensure everything was in good condition. Following the inspection, Miguel provided me with solid recommendations. His knowledge, professionalism, dedication to quality work, and comprehensive report gave me peace of mind. I was so impressed that I signed up for Cardinal’s $9.99 monthly service contract. “
Experienced, Comprehensive, and Very Courteous
“Cardinal just completed their routine customer care of the plumbing in our multilevel single family home. The lead plumber was experienced, comprehensive, and very courteous. He explained his findings and recommendations and gave practical advice without pushing costly improvements. I appreciated his attention to his service for us while providing guidance to the plumber trainee who accompanied him— unlike other companies who send trainees solo to do the job with experts reachable by phone. Cardinal clearly stakes their reputation on providing onsite expertise. This is why we continue to stick with Cardinal.”
Excellent Communication and Outstanding Service.
“Excellent communication, top-notch quality, and outstanding service! I’ve tried many companies, but this one stands out with its exceptional professionalism and dedication. They did an excellent job replacing my water heater, water pressure valve, and monitor. Highly recommend.”
Friendly, Professional, and Pleasant.
“I have never had a better experience with a service company. From the friendly voice on the phone, to the almost immediate schedule of repair, then the professionalism and incredible pleasant Bryan who diagnosed the problem, repaired the issue {actually had the part on the truck} and provided pleasant conversation the whole time! Cardinal Plumbing was a complete joy to work with and reasonable! Thank you.”
