Are refrigerator air ionizers any better than baking soda?
There are many models of little battery operated fridge air purifiers available, but there aren’t many reviews that I can find. These things ionize the air and create small amounts of ozone that are supposed to keep mold, bacteria and odors to a minimum. Are they worth buying or should one just stick with the old baking soda in the fridge standard?
Ok, so a box of baking soda isn’t the gold standard, but has anyone out there tried one of the fridge air ionizers?

Actually this was covered on Food Network’s Food Detectives show. They did some experiments and determined that Baking Soda didn’t do such a great job because there was so little of the baking soda’s surface area exposed to absorb the odors.
They recommended spreading it out on a cookie sheet and even better than baking soda, use activated charcoal. But the best way to keep your fridge from smelling, they found, is to just keep all foods tightly sealed and keep the fridge clean.
I saw that program on the Food Network too and they agreed that activated carbon was much better than baking soda. The product that they showed (little purple cube) was a product that I’ve used for a long time now called FRIDGE IT activated carbon odor absorber. It works really great. Don’t spend your money on expensive battery operated things. Just get some of the Fridge it odor absorbers. I keep one on each shelf and produce bin and I haven’t had any smell at all . Love it! I just get them on line at http://www.innofresh.com Also, pretty good blog that you can also link to with much more information.
Anyway, the FRIDGE IT odor absorbers work great and are not expensive. By the way, also use these in other places around my house like trash, under sinks, cabinets, etc.
