Lowes or most hardware stores make sure to take old one out and write down size. If you have animals or allergies pleated filters catch more air particles but if not the cheap fiberglass alllowd better airflow
Take existing one to Home Depot. They'll match the size to yours and give you the range of options based on price (and this filter quality). The higher the price, the more stuff the filter catches.
