I always shop for the best product at a fair price. This is it! I purchased the 7,000 mg/hr bare bones unit for several reasons - shock treat large or small areas - eliminate musty smell in our 1,600 sq ft basement and to maintain the whole house (via HVAC w/ a timer). I have used it for a week and could not be more pleased - basement smells fresh as a daisy.
I was skeptical due to the low price, especially when competitors are so much costlier. But I was amazed at the output of this basic unit. 2 day shipping was free, and I am a happy customer! It removed the smoke odor in one treatment.
