Why would I get a whole house water filtration system versus a drinking water filtration system?

Whole house water filter systems are installed where your water enters your home, so they can provide filtered water from every tap and to every appliance. These are designed to address specific water issues. Alternatively, drinking water systems are installed at a single water connection, typically under the sink in the kitchen. These systems tackle a broad range of potential contaminants.


A whole house system is the best choice for water issues that negatively impact not just drinking but bathing, cleaning and any broader water use. These include problems like a chlorine or rotten-egg smell, hazy water from sediment, corrosive water from low pH, rust stains or a metallic taste from too much iron, or others.

The Aquasential Smart High Efficiency Water Filter is most often used as a well water filter. It can address many well water problems, including low pH (acidic water) or issues like dirt, silt, clay and other types of sediment that can create cloudy, dirty water. If you are dealing with more than one well water problem, you may require multiple solutions — such as additional whole house filters for iron or hydrogen sulfide, a reverse osmosis system or a water softener. With a free, in-home water consultation, your local Culligan water expert can help determine what systems your home may need.

The Culligan Smart HE whole house water filter system can help address sediment, chlorine and acidity issues within your water supply. Our other whole home solutions can address issues like rotten egg smells and rust stains. For hard water, Culligan offers state-of-the-art water softeners that can help enhance skin and hair, brighten laundry, reduce buildup on faucets and much more.

It is recommended to schedule a free, in-home water test to get to the bottom of your water problems and get personalized recommendations for the best solutions.

Schedule a free, in-home water consultation with your local Culligan water expert. They are familiar with local water concerns and can determine what else may be in your specific water supply. From there, your Culligan water expert can recommend the best system for your home. Once installed, they’ll typically test the water before leaving to ensure your system functions correctly.

How often do I have to replace the filters?​

The CULLAR and Filter-Cleer can last for several years in many applications. Your local Culligan water expert can replace these filters when needed. The Cullneu filter is consumed in the neutralization process. It will need to be periodically replenished by your Culligan service team to ensure the proper level of pH elevation.

Since whole house water filters are specially designed to target individual, specific water problems, you may require multiple systems to address all your concerns. In addition to the Aquasential Smart High Efficiency Water Filter, Culligan also offers iron, sulfur, hydrogen sulfide and arsenic solutions. You can compare these systems here.

A properly sized system should not significantly impact your water flow or pressure. If your water has sediment issues, that can decrease water pressure, a whole house sediment filter would improve this problem.
