The information says "adds minerals like". instead, can you specifically list all items that it adds to the water? Certain items may be a concern for some people.

Asked by: Brandon

Is the Clarifi BPA free?  Meaning, is there BPA in the plastics?

Asked by: Greg
Hi Valued Customer, Thank you for your question regarding our Delta Faucet. While we cannot be certain that every component of every product, we sell is BPA-free (since we don’t often have access to proprietary formulas of parts of components supplied by third parties), we can say with confidence that all products sold for residential use, or for dispensing of water for human consumption, are BPA-free. Please feel free to contact us directly for technical information at 800-345-3358. We are available Monday through Friday from 8 a.m. to 8 p.m. and Saturdays from 9 a.m. to 6 p.m. Eastern Standard Time. Thank you for being a loyal Delta Faucet customer.
