Here is how I reduce odor at home: coffee pods.
I think you already knew that coffee absorbs aroma from its surroundings and sometimes replacing it with a good aroma of coffee.
Simply place some coffee pods in several spots in the fridge. Bottom drawer, middle racks and door shelf.
I did a little hand sew to the side of coffee pod, so it can be placed hanging on the bathroom.
If you do not have any coffee pod, simply wrap some ground coffee in a fabric, tied with elastic. Or simply put ground coffee in a little pouch. I am using reusable tea bag from Tealovero Shop, here.
Hope this little tip could help you making home much more comfortable. Good luck and have a pleasant day.
