Wonderful!
Amazing!!!! We had a new HVAC installed and the guys told we that they needed to do some welding and there would be a very bad burning smell and smoke.  So I opened up all the windows upstairs thinking that I was about to be smoked out. The basement is a closed basement. When the guys finally came upstairs I asked them when the were going to start welding. They were finished. I went downstairs and the machine was working overtime. Only a hint of burning smell was in the air. Definitely worth the money!!!
