I purchased this product a few months back. I was in desperate need of eliminating the mildew odor in my basement. When I received the pouches, I didn't immediately open them and put them out (not that it should have made a difference).
Upon opening the merchandise and leaving them out for almost three months, I notice that the mildew odor became worst, especially after it rained. I eventually went to Home Depot and purchased a product, DampRid and placed it in my basement. After just three days the mildew order was gone.
I purchased three bags of the NatureFresh air purifier for more than $30 to receive no results. I purchased three bags of the DampRid in a starter kit box for just under $11 and my mildew problems are over.
I contacted the company and informed them of the issue I was experiencing with their product. They were more concerned with not providing a refund, rather than Customer Satisfaction.
Therefore, I say to you, buyer beware, DON'T BELIEVE THE HYPE about this product! Save yourself some time, energy and money, go to Home Depot and get something that works.
Bottom Line: No, I would not recommend this to a friend
