Can you help me find a model to a window ac unit

Question

Its a whirlpool DesignerStyle unit, very large and noisy. It was gifted to us and we installed it without writing down the model number off the sticker on the side. Its attached very well with sheet metal and wood, and would take some tools and a very strong human to move it. The filter is dry rotted and I need to replace it, but so far I haven't been able to locate the rest of the model number or even a place on line that might have universal filters. The number I have is O184XX1. The first number might actually be a Q, I'm not sure. Than you for looking!

Answer 1

they have universal filters at home depot Lowe's and even walmart

Answer 2

If it has air vents on each side and the filter slides in from the top it is probably a ACQ184. If it has heat it will be an ACE184 But they use the same filter.You can order original parts by that at a whirlpool dealer or Sears in store or on their parts site.The universals don't work very well on those. Due to the wide hole at the top and sliding down the track.But would work better than nothing at all.
