A window fan incorporating a filter. The fan has a low, flat profile for fitting in a window while occupying limited viewing area of the window. The fan includes laterally projecting extensions for sealing a gap which might otherwise exist at the right and left sides of the fan. The fan includes a motorized squirrel cage blower for forcing air through a flow path defined within the window fan. The blower is elongated, and oriented with its rotational axis arranged horizontally to enable the low profile. The filter is washable, and is installed by sliding into a holding chamber, and located serially within the air flow path. The window fan has a manually adjustable air deflector for directing discharged air as desired. The electrical circuit conducting power to the motor includes a touch sensitive switch for on-off control, a thermostatic switch for operating the fan when the touch switch is on and a predetermined temperature is detected, a speed selector switch, and an indicating lamp.
