Lasko Air Flex 2-in-1 20-inch Box Fan and Air Purifier in One with MERV10 Air Purifying Filter for Cleaner Air and a Cooling Breeze FF305

by Lasko
What We like

AIR PURIFIER AND ROOM FAN IN ONE The FF305 is both a premium box fan and air cleaner. It features steel body construction, plastic front and rear grills, and a premium fan motor and blade for maximum air flow. Unlike most box fans, which can overheat or break down when used with a filter, this powerful 3-speed fan was specifically engineered to work with a filter to clean the air in your room while providing a cooling breeze.

Product Features

  • CUSTOMIZE YOUR CLEAN The floor fan comes with a standard pleated filter that is MERV10 rated to remove dust, smoke, and pollen from the air so allergy sufferers can breathe easier at home. Even though the fan comes with a filter, you can still customize your clean with any standard 20 x 20 x 1-inch filter. The Lasko YY305AF Replacement Filter Pack is designed to work with the FF305.
  • SAFE FOR WINDOW USE - This portable electric fan was designed to stand up to tough use with a durable steel body construction, UV color protection paint, and a Weather-Shield motor for worry free window use in your home or apartment.
  • SIMPLE BOX FAN DESIGN Ergonomic controls are top mounted, not on the back, so theres no need to move the fan to change the speed or turn it off. The 6-foot cord is hard wired into the motor, so you never have to worry about losing it. The cord exits the fan at the bottom, not the middle, making it easier to position in a bedroom window or in front of a kitchen screen door.
