Review on OXO Good Grips GreenSaver Carbon Filter Refills - 4 Pack by Devin Maselli

Extends the life of fruit and vegetables very well. I have stored bananas for up to 11 days using these charcoal filters and the bananas have still tasted pretty good. The skin was beginning to darken, but the inside was still fine. I put these charcoal fillers on top of the bananas and every time I ate a banana I would take the plastic container out of the fridge and vent it to get fresh air back into the plastic and blow out the rot gases. Cut the stems close to the bananas because the stems give off the most gas, according to my daughter, who has a PhD in chemistry. The biggest advantage for tomatoes. Tomatoes retain their texture and flavor much longer than usual. I haven't had a bad tomato since I started using these activated charcoal fillers. Fresh strawberries are much more difficult to protect from mold, but this helps a lot.
