We had kimchi in our fridge. No matter what we tried to seal the container, the smell leaked out and other foods in the fridge absorbed the smell. Fruits tasted disgusting because of that. I purchased this and put one in my fridge - boom! Next day, just in one day, the odor is almost gone! It took 2 days to become completely odor free, but it works and I am very happy about it. No more disgusting fruits!
