grow room massive carbon scrubbers

former tenant evicted from home from owner. I have these 3 huge ass carbon scrubbers left over sitting in my garage and want them gone. 2 of them are 60" with a 10" duct and the short one is a 30" with a 10" duct. All are activated carbon scrubbers with only 1 apparently slightly used before the landlord kicked him out. These are very heavy and a must for someone who wants to grow without the aroma wandering into the nose of those around you. they gotta go but not gonna give them away either. price is slightly negotiable...
