Here’s an unsolicited promo for you & Berkey–
My wife & I used our Sports Bottles while I was an inmate, er inpatient, at my VAMC (Veterans Admin Medical Center). I was in for nearly 12 days. The Nurses were great in keeping the water pitcher full, but, we needed to filter it.
A world of difference. We have well water at home which we filter through our larger Berkey system, and, the smell and taste of city water (Dayton OH) was pretty bad. Also, the plastic hospital pitcher left a plastic taste. Our Bottles removed all of it.
