Federal Trade Commission (FTC) says, "most home air purifiers fall short" 
2008-08-14
UV purifiers. These devices rely on ultraviolet light to neutralize biological contaminants. Experts agree that UV light is effective in destroying microbes such as bacteria, dust mites and mold spores, given sufficient exposure time. According to the Federal Trade Commission (FTC), however, most home air purifiers fall short: "Bacterial spores would require a relatively long time under the light for the light to have a killing effect. Most household air cleaners move air too quickly to provide adequate exposure time." Without the addition of a filter and fan, UV purifiers are ineffective against particles such as dust, pollen and pet dander, and some experts have raised concerns about the safety of UV units in household settings.
loud fan 
2008-04-18
I bought one of these from the local Lowe's and returned it. The fan in it was loud even on the lowest setting. This would have been fine if it were moving a lot of air, but as the others on here have said it barely moves air.. so why all the noise? It was louder than my computer.
Also, it doesn't need to move a lot of air through it to treat all of the air in a room over the course of 24hrs.
I'll try another at some point.. and if it's loud then I'll swap the fan for a higher quality one.
This is a gimmick! 2008-01-16
When I first learned about the Germ Guardian, I thought, "Wow! I've just got to have it!" The manufacturers claimed that it was tested and found effective by the Harvard School of Public Health so I was impressed and ordered it. It turned out to be a slick looking product, space age and all and it looked good in the house but unfortunately, that's the only good thing I can say about it because after 5 days, my sneezing (I have allergic rhinitis) was no better, I felt the same as I did before it arrived and then, one day, I came down with an absolutely severe allergic attack and this thing did absolutely, 100% NOTHING!! So I have sent it back for refund. I don't recommend it at all and I feel that the whole thing is just a big bad gimmick.
POOR QUALITY 2007-09-13
POOR QUALITY, FAN MAKES NOISE AND YOU CAN HARDLY FEEL ANY AIR MOVEMENT, THIS IS A PIECE OF JUNK!
Marketing Scam 2007-04-11
I bought two of these pieces of junk, and believe me they do NOT work unless your room is about 3 feet by 3 feet by 3 feet.
IT RECIRCULATES THE SAME AIR OVER AND OVER IN A TINY AREA!
When they say it cleans 700 cubic feet per hour, that is simply what the fan can MOVE per hour not what it actually will clean in a 10 foot by 10 foot by 7 foot room.
The fan is so weak at full speed you can barely feel it. Really it is sucking in air through the bottom and blowing it out at the top. Both the inlet and outlet are facing the same side so you are basically recirculating most of the same air over and over again. This thing would need to be 7 feet tall to really work well.
In a hospital they have HUGE systems that MOVE the air past LARGER ARRAYS of bulbs.
So here you are sitting in a room with your kids coughing on one side and this thing recirculating the same air over and over again, in a little tiny airspace, what a great deal. Just be ready to buy 10 of them per room.
Maybe you can try hanging 5 on the celiing and putting 5 on the floor of a 4' x5' bathroom and it might work in a week.
Do yourself a favor, and buy a machine that has more UV light bulbs, and has a greater airflow so ALL the air in a room is moving and ALL of the air in the room goes through the filter.
I gave it a one because it looks nifty.
Decent product but does not cover room adequately 2007-03-31

IT WORKS!!! 
2007-03-08
My wife works at a health clinic and I was constantly getting colds and sniffles ETC from the "bugs" she was around all day. Since we got this little gem (3 months ago)I haven't once had any germ/virus related symptoms. It's a little pricey but it beats having a cold for weeks on end. Plus it's very cool looking. My advice to anyone that is susceptible to colds and the flu, get one of the babies, hook it up in your bedroom and run it 24/7 at full speed (you won't even hear it). And for people looking for the replacement UV lamp, just Google Germ Guardian and they have all the parts for all their units.
great product-best purchase I've made! 2007-01-19
I purchased one of these for our great room and I also purchased the GG-1000 model for my sons bedroom. Our Family had been passing around soar throats, colds and the kids had ear infections since October. They would get better from the antibiotic and as soon as they were off it, they would be sick again. Since putting this in our home, (knock on wood) no one in the family has had a cold and that is awesome, especially because of the holidays and all the stomach flu-like symptoms that were going around...we didn't get it!!! I have ended up putting one of the GG-1000 UV models in every bedroom and one in the kitchen as well. I highly recommend this unit based on the few months we have owned them.
Germ Guardian ev-9-102 uv-c Air Sanitizer, Black 2006-11-25
The UV light went out on the sanitizer five days after using 24 hours a day. There is no restriction as to the amount of usage. Where can you get replacement lights?
Thrilled Mom 2006-05-30
I'm thrilled with this product. It has made a tremendous difference in our home. It really does control the spread of germs. I can't tell you how exciting it is not to have my three children continue to reinfect each other. I highly recommend getting a couple, one for the bedroom and one for the family room. You won't be disappointed!
