Q: Are there home drinking water treatment devices that can be used to remove chloramines?

A: Yes. Home drinking water treatment devices that remove chloramines are filtration systems with granular activated carbon or charcoal. The National Sanitation Foundation (NSF) independently tests and certifies water treatment systems for chloramine removal. Information on NSF Certified Drinking Water Treatment Units can be obtained either on NSF's Web site (http://info.nsf.org/Certified/DWTU/), or via email info@nsf.org.

Other at home alternatives include placing few slices of orange, lemon, mango, apple, or strawberries in a glass or water pitcher as well as steeped tea for few minutes, and coffee. For bathing, vitamin C shower heads can be purchased on the internet, and vitamin C tablets can be used for baths."

Vitamin C showerheads exist. Who knew? More so, chloramines in the water supply can be remediated with ascorbate; this is a boon to both humans and their pets, especially fish, that cannot make their own vitamin C.
