Nearly all your major appliances in your home have a filter that needs replaced or cleaned on a regular basis (fridge, HVAC system, dishwasher, dryer, etc.). Doing so and doing a quick clean of the appliance will improve its efficiency, life span, and most importantly save you on your electric bill.
Not sure where the filter is or what maintenance to do? A quick Google search of "how to clean fridge filter" or "where is the air filter for my heat pump" should start to give you an idea of what needs done.
I very much imagine it would be. It's the same as when they put 'gluten free' on ridiculous stuff like raw meat, packaged raw vegetables, raw nuts, and the list goes on.....
