What Your Water Filter Pitcher is Leaving Behind Dr. Janine examines the residual substances that your water filter pitcher fails to remove. It is important to note that these particular filters do not effectively eliminate fluoride, microplastics or lead from your water. However, they do successfully remove chlorine, copper, cadmium, and mercury. For optimal filtration results, Dr. Janine suggests considering a reverse osmosis system with a re-mineralizer or acquiring spring water sourced from higher elevations in the mountains. #waterfilters #nutrition #bestwater
