Frequently Asked Questions
How much does a home water filtration system cost?
The cost of a whole house filtration system depends on several variables including the type of system, what features are included, quality, durability, and more. Fortunately, Culligan has flexible payment options (including financing and rental) to fit every household. Our initial in-home water test and consultation are also always free.
What is a reverse osmosis water filtration system?
Reverse osmosis is a method that can be used in water filtration to help reduce unwanted minerals, substances, and other impurities in your drinking water. RO systems use pressure to push water through a tightly woven membrane designed to filter contaminants as small as a single atom.
What is a whole house water filtration system?
A whole house water filtration system is designed to address specific water quality issues that impact not just your drinking water but bathing, cleaning and other uses as well. Installed where your water enters your home to provide cleaner, safer water from every tap, these systems can address contaminants like PFAS, chlorine, iron, arsenic and more.
Can a water filtration system improve the taste of tap water?
Yes. In fact, it’s one of the key reasons why many homeowners choose a water filtration system. The right system can filter out the specific contaminants causing foul tastes and smells, giving you cleaner, fresher-tasting water. To find out what’s in your water, schedule a free consultation with your local Culligan experts. We’ll conduct a free in-home water test and recommend the best solution based on your results.
What contaminants do standard water filters not remove?
Standard water filters like pitchers and refrigerator filters typically can only address a limited number of water quality issues, commonly focusing on aesthetic issues like chlorine. They aren’t likely to protect against viruses, bacteria, arsenic, microplastics, nitrates and many other contaminants that are addressed by highly comprehensive systems like Culligan’s Aquasential® Smart Reverse Osmosis drinking Water System.
How often should I change my water filter?
Different types of filtration systems have different requirements for filter changes, and filter life also depends on the quality of your local water supply and your usage. For Culligan’s whole home filtration systems, filter media can last several years. For our reverse osmosis (RO) systems, filters typically last 1-2 years and the RO membrane lasts 3-5 years.
