Whole-home Water Filtration Systems & Water Softening
Water touches nearly every part of daily life – from drinking and cooking to bathing and cleaning. There’s no question it’s worth making sure the water you use in your home is as pure and safe as possible. Even treated municipal water can carry trace chemicals, sediment, or minerals that affect your health, your plumbing, and the overall quality of your water.

Whether you rely on city water or a private well, we provide lab testing, water quality assessments, and expert installation. We also inspect and maintain existing systems to keep them running efficiently.

Water Filter Installation Services for the Whole Home
Capital offers a whole-house water purification and softening systems that connect to your home’s main water supply directly after the meter. This means that water goes through the filtration process before it’s used or consumed by any fixture in the home. You’ll notice immediate benefits such as:
- Cleaner, safer water for showers and baths – something that’s especially important for those with sensitive skin.
- Spot-free dishes and glasses straight from the dishwasher
- Longer-lasting fixtures & appliances with less calcium and mineral buildup
The difference in your water quality is truly amazing!

Safer Water for Your Family
Our water filtration system removes chlorine, volatile organic compounds, arsenic, pesticides, herbicides and other solvents that find their way into our water supply.
City Water
- Chlorine & Chloramine: Used to disinfect municipal water, but can cause skin irritation and an unpleasant taste or odor
- Volatile Organic Compounds (VOCs): Industrial byproducts and chemicals that can make their way into the water supply
- Lead & Heavy Metals: Often introduced through aging pipes and plumbing infrastructure
- Sediment & Rust: Fine particles from the distribution system that can impact clarity and appliance lifespan
- Trihalomethanes (THMs): Chemical byproducts of chlorine disinfection linked to health risks with long-term exposure
Well Water
- Iron & Manganese: Naturally occurring minerals that can stain fixtures and give water a metallic taste or odor
- Sulfur (Hydrogen Sulfide): Causes a strong “rotten egg” smell and can corrode plumbing
- Bacteria & Microorganisms: Including coliform and E. coli, which may enter through surface contamination
- Nitrates & Nitrites: Often from fertilizers, septic runoff, or animal waste, posing serious health risks, especially to infants
- Sediment & Silt: From soil runoff or well casing issues, leading to cloudy water and potential damage to appliances

Whole-home Water Filtration FAQs
-
What does a whole-home water filtration system do?
A whole home water filtration system treats all the water entering your house, not just at a single tap. It removes contaminants like chlorine, sediment, and heavy metals before the water reaches your faucets, showers, or appliances. This means cleaner, safer water throughout your home, from drinking and cooking to bathing and laundry. -
How is a whole home system different from a faucet or pitcher filter?
Faucet and pitcher filters only treat small amounts of water at the point of use, like your kitchen sink. A whole home system filters all water as it enters the house, offering full coverage for every tap and appliance. It’s a more comprehensive solution that protects both your health and your plumbing. -
Do I need a water filtration system if I’m on city water?
While municipal water is treated to meet basic safety standards, it can still carry chlorine, lead, sediment, and other trace contaminants. A filtration system adds an extra layer of protection and improves the taste, smell, and quality of your water. It also helps reduce wear on plumbing and appliances over time. -
How often do whole-home water filters need maintenance?
It depends on the type of system and your water quality, but most filters need replacement every 6 to 12 months. Some systems have multiple stages with different timelines. -
Will a filtration system affect my water pressure?
A properly installed and maintained system should not noticeably reduce your water pressure. We size each system based on your home’s needs to ensure strong, consistent flow throughout your house. -
What are the signs I should look for that it’s time to have my water filtration system serviced?
Your water filtration system is like any other utility system in your home – it needs regular servicing to stay in good working order. A few signs it’s time to schedule maintenance:- Your skin feels dry or “squeaky clean” after a shower This means hard water minerals are no longer being filtered out — softened water should feel slick or “slimy” due to natural body oils staying on your skin.
- Visible limescale or soap scum buildup If you’re noticing white residue on shower doors, faucets, or dishes, it’s a strong indicator your system isn’t effectively removing hardness minerals.
- Clothes aren’t coming out as clean Hard water can leave mineral deposits on fabrics, reducing the effectiveness of detergents and making clothes look dingy even after washing.
- Appliances and fixtures show signs of scaling Dishwashers, washing machines, and other appliances may develop limescale buildup, which can shorten their lifespan.
- Changes in taste or performance of tap water If coffee tastes off, noodles cook differently, and there just seems to be something a little “off” with the food you cook in water, it could be a sign your filter media needs replacing.
- The water no longer feels “soft” If the water loses that silky feel, it may be time to “rebedding” – replacing the internal media that removes minerals and contaminants.
