Will this remove chlorine and chloramine?
The carbon media is designed to reduce chlorine taste and odor common in city water.
Will it reduce pressure?
Designed for full‑home flow when sized right. Select the capacity that matches your home’s water usage.
What about maintenance?
Periodic salt refills for the softener. Lifetime saltless media, along with long-life carbon media that require simple service intervals, are available for up to 1 Million Gallons or 10 Years, whichever comes first.
