My doctor recommended to switch to this water purification system. I have osteoporosis and used a reverse osmosis system in the past. RO eliminates calcium from the water which is a much needed mineral, especially for someone with osteoporosis or osteopenia. Pure Effects does not to my knowledge filter out calcium. On top of that the taste of this water is alive and clean. I am very happy with this system.

MERCHANT COMMENT:
Thank you Susanna for sharing this. I can confirm that our systems are intelligently designed to not target natural and necessary minerals that are in the water, including Calcium. This can be verified with an inexpensive TDS (Total Dissolved Solids) meter from amazon, which primarily measures the dissolved minerals. The reading from the filter should be close to the reading from the tap water, confirming that naturally occurring minerals remain.
