The only maintenance required will be to occasionally vacuum the 4 sides of the air cleaner to remove larger dust particles. Austin Air filters are designed to last up to 5 years under normal residential use, so you won't be bothered with frequent filter replacements.
The Austin Air cleaner should be placed at least 4 inches from the wall, allowing air to be freely drawn into all sides of the air cleaner. This will ensure maximum efficiency and performance. Every Austin Air cleaner features a 3-speed centrifugal fan offering a low, medium or high speed setting.
