My husband and I are both in our seventies, and for the past year we've been dealing with occasional stomach discomfort. Our doctor suggested the usual things—adjusting our diet, trying probiotics, and making a few lifestyle changes. We tried just about everything, but nothing seemed to make much difference for long.
Then our daughter read about refrigerator contamination and bought us a couple of these. She didn't explain much—just placed them on the shelves and told us to trust her.
Within a few weeks, we noticed a real difference in how fresh our refrigerator felt and smelled. Around the same time, both of us felt better overall. We hadn't changed our food, routine, or medications, so it was one of the few things that had changed in our kitchen.
We'd been using baking soda in our fridge for years, but it never seemed to make much of a difference. Looking back, I only wish we'd learned about this sooner.
We ended up buying three more for our children's homes. They have kids, and we like the idea of helping keep their refrigerators fresher too.
