EPA warns against ozone air purifiers
After doing some reserch, I purchased this for my son's dorm room.  Best part - it really kills odors and I hope germs and it doesn't produce ozone which the EPA is warning about in other air sanitizers.  The only con is the noise.  My guess is it wouldn't work without the fan so it's just the price you pay for an affordable, safe, sanitizer.
