I use it in the house, I use it when I’m out for the day, when I’m in the studio, my daughter can use it & I know she’s drinking safe filtered water, where ever we are – I use it anywhere, & buying bottled water is a thing of the past.
Where it’s really made a difference is when I’m on tour or on the road; I can fill up from anywhere & in countries where you wouldn’t go anywhere near tap water I don’t have that problem. It’s the best product out there of it’s kind, nothing else even comes close and I know because I’ve tried them all.
