Point-of-use filters address the water at a single tap. They are useful, but they leave everything else in the house unprotected. Your showers, your laundry, your ice maker, your water heater, and every pipe in the home are still receiving unfiltered water.
Whole-house filtration installs at the main water line before it branches out to serve the rest of the home. Everything downstream of that filter gets treated water. That matters for water heater efficiency, appliance longevity, fixture appearance, and the quality of water you are showering and washing clothes in, not just what you drink. If your softener already handles hardness, this is the next piece of a complete Water Softener Installation setup, addressing everything hardness doesn't.












What Gets Protected With Whole-House Filtration
Water Heater
Sediment and scale build up inside tank water heaters over time, reducing efficiency and shortening service life. Filtered water entering the tank reduces that buildup.
Fixtures and Faucets
Chlorine and hard minerals contribute to scale and corrosion on fixtures. Whole-house treatment slows that process throughout the home.
Shower and Bath Water
Chlorine absorbs through the skin and is inhaled as steam. Removing it at the point of entry means cleaner water for bathing, not just drinking.
Laundry
Chlorine degrades fabric fibers over time and fades colors. Filtered water is gentler on clothing.
Appliances
Dishwashers, washing machines, and ice makers all benefit from water that has had sediment and chemical content reduced before reaching them.
Not Sure Which Filtration Approach You Need?
If you're not sure yet what's actually in your water, a Water Filtration System Installation starts with testing and diagnosis before recommending equipment, the right call if you haven't pinned down the specific problem. If drinking water quality at the kitchen sink is your only concern, a Reverse Osmosis Installation treats that one tap without the cost of a whole-home system.

How We Design a Whole-House Filtration System
Assess Your Water & Goals
We look at what's in your water, your household's flow rate, and what outcomes matter most to you, there's no one-size-fits-all system.
Design the Right Configuration
A common setup is a sediment pre-filter followed by activated carbon for chlorine and chemical removal, with an oxidizing stage added for homes with iron or sulfur. Well water often needs more stages than municipal supply.
Size for Your Home
We size the system so it doesn't create pressure problems at peak usage, sized for your actual household, not a generic default.
Install at the Main Line
Installation happens at the main supply line before it branches into the home's distribution system. Most whole-house installations are completed in a half day.

Whole House Water Filtration Cost in Okemos, MI
Cost varies based on the number of filtration stages, the system capacity, and what the installation requires at your main line. A basic two-stage system is more straightforward than a multi-stage setup with backwash filtration. We give you a clear price before any work begins. Ongoing costs include filter cartridge replacements on the schedule we set up during installation. We walk you through exactly what maintenance looks like for your specific system. Call (517) 742-2848 to get started.
Why Choose Plumbing by Custom Built
Whole-house filtration is a plumbing installation, not just an equipment purchase. The system needs to be sized correctly, installed at the right point in the supply line, and set up with proper bypass valves. We do this correctly from the start.

FAQs
Does whole-house filtration remove bacteria or make well water safe to drink?
Not on its own. The filtration stages we install address sediment, chlorine, iron, sulfur, and similar contaminants, not bacteria or pathogens. If a water test shows bacterial contamination, that requires a different treatment approach, like UV disinfection or shock chlorination, which we can discuss separately from filtration.
Will whole-house filtration reduce my water pressure?
A properly sized system installed correctly will have minimal impact on pressure. We size systems based on your household's peak flow rate to make sure you do not notice a difference at the tap.
How is whole-house filtration different from a reverse osmosis system?
A reverse osmosis system is a point-of-use filter, typically installed under the kitchen sink, that produces high-quality drinking water at that one location. Whole-house filtration treats all the water entering the home. They serve different purposes and work well together.
Do whole-house filters require electricity?
Most basic filtration systems are passive and do not require electricity. Systems with backwash cycles or automatic regeneration typically do. We walk you through the requirements for whatever system we recommend.
Can I install whole-house filtration if I'm on a private well system in Okemos?
Yes, whole-house filtration works well alongside a private well system, and well water is actually where it's needed most, since it doesn't go through municipal treatment first. We coordinate the filtration system's placement with your pressure tank and well pump setup during the assessment.
