Pure Air, you saved the day again when you managed to remove the smoke inside a home. My Seller was starting a new job out of state and needed to get her property on the market fast. I knew the home would sell quickly if we could get rid of the smell of cigarette smoke that greeted you at the front door. As usual, you leaped into action and placed three Odor-Ox units and removed every indication a smoker had ever lived in the home. As a result, we sold in one day. Thank you Pure Air Environmental.
