Product review (5 stars): Works well and gets rid of strange stale odors.
I need to replace the filter in my Electrolux fridge and this did the trick. Before I was using Arm & Hammer baking soda to try and eliminate the odors in my fridge. I had like 3 boxes in the fridge and it still didn't work. Here are the steps I took to get my fridge smelling new again:

1. Obviously throw out any old food that you're not eating. This goes for condiments that haven't been used in months.
2. Deep clean by first getting rid of stuff in step 1 and then cleaning out all the drawers. I was able to take out my shelving and clean it with Dawn dish soap.
3. Get rid of those baking soda boxes. They don't really do anything.
4. Get this replacement filter. I guess I hadn't replaced my filter in years so this was the magic bullet. On top of general cleaning.

That's all folks.
