Which Minerals!???

I called P&G Custoer Service to ask which minerals are included in the PUR MineralClear faucet mounted wayer filter. The answer? "Natural minerals for a crisp, refreshed taste'" That was what I read right on the box!!!! I asked which minerals would those be? Her response was, "You mean the actual minerals that make up the filter?" I was ready to pull her through the phone. After saying yes, the actual minerals I was placed on hold. After 12 minutes on hold the canned music went off. I held for 3 more minutes. since they announce all calls are recorded, I left my name, phone number, and email address hoping above hope I'd hear back. Right!  SO, WHICH MINERALS ARE ACTUALLY IN THE PUR MINERALCLEAR FAUCET MOUNTED WATER FILYER?
