Air Box Junior Replacement Pre-Filter - 11.5 x 1.8 x 11.5-in

Keep Dust Out of Your Carbon Filter - 11.5 x 1.8 x 11.5 in

Dust, spores and other airborne particles clog filtration media and shorten its working life. A pre-filter stops much of that material at the intake, so downstream filtration stays cleaner. This replacement pre-filter is a disposable, replaceable unit you swap out when it loads up.

At a compact 11.5 x 1.8 x 11.5 in and sold singly, this is a practical stock item for hobby and small indoor growers, and an easy spare for commercial rooms running a matching Air Box Junior unit.

• Disposable media — no cleaning step during maintenance.
