Product Description

The Dirt Devil and Royal Roommate Exhaust Filter (part 3400321044) is an OEM replacement exhaust filter designed to trap fine dust, allergens, and particles in your upright vacuum. This filter sits at the vacuum's exhaust port and is the final line of defense before air exits back into your home, ensuring cleaner air circulation and protecting internal motor components from fine particulate matter.
