Can I do away with my furnace filter and install a return grille air filter instead?
I would rather have a return grille air filter instead of using a furnace filter because of the confined space my central air/furnace is located in.
Also, out of sheer curiosity. Are there any repercussions in using both filters?
Francis G is right, with one other note. The assumption is that you only have one return air grille. If you have multiple return airs, you would need a filter in each one. That's why you usually find the filter in the unit, because it will filter all of the return air, including any outside air that might be brought in through the ductwork (not common in residential though).
