We have a cabin that's has flooded and has mildew smell that won't go away. With one use we could tell a difference. I'll be trying round two. 👍👍

Great customer service - product arrived on time.

Hard to tell if the musty smell is gone. We left it out in 400 sq foot area 8 hrs and 8 hours in spare bedroom overnight. Open windows for 2 early hours at start of day. When you live in these conditions it’s hard to tell if it’s gone away or I just am used to smell. Time will tell, wife had a reaction in nose to the Biocide order. Fresh air really helps.

Really interested in using the product but no directions were included. I reached out to their website. It’s been five days. I still haven’t heard back.

I have to say I was a bit skeptical the smell that we were trying to get rid of was fish smell from a prior business that did fish fries. We even removed all of the ceiling tiles, thinking it was embedded in the tiles before replacing the tiles we left the area above the tiles exposed, we ran two of the shock room units for 400 ft.² apiece. I left it for a full 24 hours covered up the window and the sunlight came in the next day. I could just slightly still smell the odor, but it was nothing like it was before , still debating if I should’ve run a third unit but now that it’s completely done I’m hoping after leaving it for another 24 hours I already closed the units up and disposed of them according to directions when I go back today, I will get to see if the smell is still gone fingers crossed
