After having some water damage in my basement after a storm I was concerned about mold growth even after running a dehumidifier down there so I purchased the Germ Guardian UV-C Air Sanitizer EV9102 to kill any potential mold spores floating around. I love that this model truly sanitizes the air with the hospital quality UV light. It kills 99.7% of airborne bacteria and mold spores without the use of any chemicals. This is especially important as I have furry babies and don't want to expose them to any unnecessary chemicals. I've found the fan to be very quiet so I can run this all day and night without having to worry about it becoming annoyingly loud, especially at night. I'm not sure about its actual effectiveness since I can't test my air but I have noticed that the air in my basement smells fresh and clean and does not have that stale odor that some basements have. That alone is worth the price of the product. I've been very pleased with my unit and will replace it with the latest unit available from this company when it comes time. I don't plan to be without one again.
