Bests & Worsts Reviews from Amazon

I have had this product for less than 30 days and the filter has black mold through out. I was prompted to take a look when I noticed a terrible smell coming from it. I am disappointed that the filtration system for this product is so inefficient at preventing mold and mildew in a such a short period of time. I used as directed with Distilled water so I will be sending this back this weekend and trying a different product
