I have two air-conditioner/furnace filters to clean the air as it circulates when I run either the air conditioner in summer or the furnace in winter.
I have a big whole-house water filter in the garage where the water supply enters the house. In addition there is a filter in the refrigerator, which filters the water that either goes into the ice maker or goes through the drinking water spout.
What filters are in your house?
What are some filters in your home?
What's the purpose of each filter?
