We demonstrate spatiotemporal cleaning of a femtosecond laser pulse impinging on two counterpropagating filaments in air. The retroreflected signal essentially has a perfect beam profile. Prepulses present in the incident pulse are also efficiently removed. The performance of the "filament mirror" is explained by a plasma-mediated wave mixing process that can be viewed as a transient three-dimensional hologram.
