You can buy off brand replacements on Amazon for a fraction of the cost of OEMs and they also sell a small battery powered rechargeable unit that produces a small amount of ozone and it does the same thing and long term is much cheaper.
Yes, it serve that purpose and you can get less expensive off brands and/or play with a rechargeable battery gizmo if you like. OTH, you can just use some baking soda in an open dish as folks have done for decades for a clean smelling fridge interior. All the items you mentioned are more costly solutions to a non existent problem if you go the backing soda route.
