Better-Tasting City Water Throughout Your Home

Municipal water is treated and safe to drink, but many Southern NH homeowners find it has a chlorine taste or odor that affects coffee, cooking, and drinking water. A whole-house carbon filtration system removes these treatment byproducts at the point of entry, so every tap in your home delivers cleaner, better-tasting water.

Common Questions

Frequently Asked Questions

Does city water need to be filtered?

Municipal water meets safety standards, but many homeowners prefer to remove chlorine, chloramines, and other treatment chemicals that affect taste and odor. A whole-house carbon filter is the most effective way to do this.

What does a carbon filter remove from city water?

Carbon filters remove chlorine, chloramines, trihalomethanes (THMs), and other volatile organic compounds (VOCs). They significantly improve the taste and odor of municipal water.

Will a city water filter also soften my water?

No. Carbon filters do not remove hardness minerals. If you have hard water issues, scale buildup on fixtures, appliances, or in your water heater, you would need a separate water softener.

How long does installation take?

Most whole-house filtration installations are completed in two to four hours. Under-sink systems typically take one to two hours.
