Awesome filter for the $$$$
Germ Guardian Air Filter - Arkansas (Monday, May 13, 2013)
I bought this because my wife and I suffer from sinus allergies. This thing removes an incredible amount of dust and allergians in our bedroom. I clean it out about once a month with compressed air. The filter should last 8-12 months, with regular cleanings from a compressed air source. It is very quite on the lowest setting. It has high, medium and low speeds, and the UV-C bulb has not needed replaced yet and it destroys viruses and bacteria. Highly recommended for the money!! Suitable for a bedroom sized room.
