Air Flex™ Air Purifier and Room Fan

Model FF305

The Air Flex™ Air Purifier and Room Fan is both a premium box fan and powerful air cleaner in one. Unlike most box fans, which can overheat or break down when used with a filter, Lasko engineered this fan was specifically to work with a filter to powerfully clean the air in your room while providing a cooling breeze. Additionally, this portable fan stands up to tough use with durable construction, UV color protection paint, and a Weather-Shield motor for worry free window use.

The fan comes with a standard pleated filter rated to remove dust, smoke, and pollen from the air. Now allergy sufferers can breathe easier and feel more comfortable at home. Easily customize your clean air by using any standard 20 x 20 x 1-inch filter, available at home stores. Features steel body construction and a premium fan blade for maximum air flow. The control knob and carry handle are simple to grasp. Includes Lasko’s patented safety fuse technology. Made in the USA from domestic and imported parts.
