Frequently asked questions
What is chloramine and is it in my water?
Chloramine (monochloramine) is a disinfectant formed by combining chlorine and ammonia. It's used by Greenville Water, Charleston Water System, and CFPUA (Wilmington), among others.
Is chloramine safe to drink?
At the levels regulated by the EPA, chloramine is considered safe for drinking water disinfection. Some people report skin and eye irritation, and chloramine can form disinfection byproducts that remain an area of ongoing regulatory study.
Does a standard pitcher filter remove chloramine?
Generally no. Standard activated carbon pitcher filters are not designed for chloramine; catalytic carbon or reverse osmosis is typically required. ClearFlow can advise based on your test results.
Can I shower in chloramine water?
Chloramine is used at levels the EPA considers safe for household use. Some people with sensitive skin or conditions such as eczema report irritation, and choose to install a whole-house catalytic carbon system.
