Pack of 2 thick micron exhaust filters which fit inside the grey filter holder on the rear of some Eureka uprights where the air comes out. Each measures 7.5" x 3.3" x 0.25" and is white with one light green side. If more costly HEPA filtration is not desired, this filter can be used instead of the "True HEPA" exhaust filter #60285 when used with filter holder #54777.
