Whole house water filter finder

Your life runs on water. Make every drop matter.

Care for the people you love and the home you’ve made, starting with the water that runs through it.

More than the
water you drink.

Your morning coffee. A long shower. Dinner together. Water is woven into the moments that make a home. Give it the attention it deserves.

In the kitchen

A little more care.
In every glass.

The water you pour, cook with and share deserves a place in your everyday wellbeing. Start with filtration suited to the taste, odor and water concerns in your home.

Carbon filtration can address chlorine taste and odor. Specific contaminants need the appropriate treatment.

Shower & bath

Your daily reset.
Rethought.

Better water belongs in the moments you take for yourself, too. Whole house filtration carries through to connected showers and baths, beyond the drinking-water tap.

Want soft water as well? A softener removes hardness minerals and can be paired with filtration.

Around your home

Care for what
you’ve built.

You put thought into your home. Bring that same intention to the water moving through its plumbing, fixtures and appliances.

When hard-water buildup is a concern, pair filtration with suitable scale control. A filter alone does not soften water.

Start before
the first tap.

A whole house system treats incoming water at one central point. The difference follows the water through the connected parts of your home.

A few things
worth knowing.

Choose with a clear picture of the water, the system and what comes after installation.

What does a whole house water filter do?

It treats water at the point where it enters your home, before it reaches your showers, faucets and appliances. Different systems address different water concerns. The right choice depends on your water source, any test results and the flow your household needs.

Will a filter also fix hard water?

Filtration, conditioning and softening do different jobs. Filtration addresses the substances its media is designed to reduce. A salt-free conditioner helps control scale while leaving the hardness minerals in the water. A softener removes those minerals. If you want both filtration and hard-water treatment, choose a compatible combination.

Can I use one on city water or a private well?

Yes, but the treatment needs can differ. City water often brings questions about chlorine taste or odor. Wells may need treatment for iron, sulfur, hardness or other measured concerns. A well-water test is the best starting point for choosing treatment, especially if you suspect bacteria or a specific contaminant.

What space and plumbing will I need?

A whole house system connects to the incoming water line with room for installation and service. SMART backwashing tanks need a drain and an electrical outlet. Guardian upflow tanks and cartridge filters do not need a backwash drain or power. A softener adds its own installation requirements. A qualified installer should confirm the location and plumbing before you order.

How often will I need to replace the filters?

Mini and Compact cartridges generally last about 12 to 24 months, often around 18 months. Big Blue cartridges often last about 24 to 30 months. Life depends on feed-water conditions and usage. Replace sooner if you notice any change in taste or odor. Tank systems have different media and prefilter service schedules; check the maintenance instructions for the exact system you choose.

How do I choose the right size?

Start with your water, then consider the number of bathrooms, household demand and available installation space. The finder brings those details together and shows compatible options. If your water or installation needs a closer look, our team can review it with you at 1-800-934-0051.
