Removing The Old Filter
Locate the air conditioner filter cover carefully. It is usually on the front or side panel. Gently open or remove the cover by sliding or unclipping it. Pull the old filter out slowly to avoid dust spreading. If the filter is stuck, wiggle it slightly to loosen. Avoid using sharp objects to prevent damage.
