Whole House Water Filters

A whole house water filtration system is installed where your main water line enters your home, addressing problem water issues throughout your home. These systems are designed to reduce contaminants like chlorine, iron, arsenic and sulfur, providing cleaner water for drinking, bathing, cooking and cleaning.

The price can vary based on which water filtration system you choose, what features it includes, and the level of quality. Advanced options such as smart technology can play a role as well. As with many Culligan water systems, you can explore flexible payment plans and options — including purchasing, renting and financing.

Water quality can vary greatly depending on where you live and where your water comes from. That’s why the best whole house water filtration system for your home might not be a great fit for someone else.

The lifespan of a Culligan whole house water filter depends on the type of system you choose. Generally, the filtration media inside your system should be replaced based on how many gallons of water have been treated. In most Culligan whole house systems, the filtration media can last for several years; it can be replaced by your local Culligan water professional as needed.

The size of your water filter depends on several factors, including the size of your home and the number of people living there. A Culligan water expert will walk you through the best size filter for your home during your free consultation.

Culligan whole home water filters are designed to address specific water problems that tend to impact the whole home – drinking, bathing, cleaning, laundry and more. These targeted systems can address issues including PFAS (“forever chemicals”), iron, hydrogen sulfide (which causes a sulfur smell), chlorine, sediment, pH levels (acidity) and arsenic.

Installed where your water enters your home, a whole home filtration system addresses specific water problems at every tap Depending on the issue you are looking to address, that means you can enjoy water that’s cleaner and clearer, tastes and smells better, reduces rust stains, prevents corrosion, or reduces harmful contaminants like arsenic or PFAS.

Whole home systems are typically designed to address individual water problems impacting the whole home such as chlorine, iron, hydrogen sulfide and more. They’re generally point solutions that focus on a specific water quality issue rather than providing comprehensive treatment of a brand range of contaminants, which is where a drinking water solution like a reverse osmosis system would be a better fit. These RO systems are installed at the point of use, often kitchen sinks.

When installed properly, a whole home system should not make a noticeable impact on your water pressure. However, an undersized or poorly installed filter can cause reduced water pressure. That’s why it’s important to rely on experienced, trusted professionals to help you choose and install your system.
