I am obsessed with Germ Guardian plug-ins, but this one especially. I live in a small NYC apartment so whenever someone cooks something the whole apartment smells like food. When I took it out of the box and plugged it in, my apartment's air was completely neutral within like 20 minutes (and I was cooking dinner!!). Definitely recommend this!! I am buying one for every room in my apartment now because it was so effective.

I love this small plug-in air sanitizer, is really does purify the air, and made my dorm room smell so fresh. I have ordered 2 of these so far and I am about to order another one because it works a lot harder than you think it would. This little pluggable UV-C air sanitizer and deodorizer is great, I love them. I use them in conjunction with a much larger, stand-up air sanitizer. Now I am home from college and renting out the "in-law" suite that's detached from my parents house. The room the cat's litter box is in is about 200-250 sq. ft. and there is never even a hint of odor. My friends tell me that my place doesn't even smell like I have a cat. 5 stars for this one. I am actually about to order another one :) I used a pencil in the first picture for size comparasion. The black one is in our laundry room, which is unfinished and in the basement, and it does an excellent job at keeping the air clean and smelling fresh.

Not sure if it's actually doing anything measurable or if this "sanitizer" is just a marketing gimmick, to be honest, but it makes me feel better knowing it's running all day, potentially zapping gunk out of the air. UV-C is the same technology used in some hospitals to sanitize patients' rooms, so I guess the concept makes sense, but just on a much tinier scale. Certainly not whisper quiet - it sounds like somebody ~3 rooms away is vacuuming with the door closed. Not terribly loud, and you get used to the whirring noise it makes. Solid build quality, with a nice glossy finish - doesn't look cheap and fits nicely with any decor. Nice blue light, but might be too bright for some people to sleep with. -1 star just because its effect is indeterminable, so I'm not 100% sold. Plus, it's overpriced and should be *** (or at least I wish it was). Nonetheless, I'm going to pick up a couple more to throw in each bathroom and one for the baby's room.

This unit may be killing airborne germs but I don’t find it to be a sanitizer or deodorizer..

I purchased this pluggable sanitizer months ago and it is still working as well now as the first day I plugged it in. I noticed a difference from afternoon to evening the first day it arrived. I didn't think there would be any change in the bedroom where I plugged in this sanitizer, but I was wrong! I did notice that the air in the room had changed. I was amazed and so was my husband! I hope that this deodorizer keeps working like a charm; I fully intend to replace it, if I notice a change. The bedroom's dimensions are 13' by 11' which opens to a closet that's 8' by 10' ... door to closet mostly remains closed. So, you can see that my space is substantial. I think it's a miracle it made a difference.

I love this item! I just hope they sell replacement uv-c bulb.

Perfect size for use in my bathroom and the fact that you just plug it in, where there is no space for a regular air cleaner. Important in that room, especially where there is so much mold and mildew because of moisture. Awesome and I recommend. Very good brand.

This is my 3rd purchase of GermGuardian Air purifier. As a matter effect, I like this one better, its my quieter that the one I've previously purchased! Very happy with this product for use in a small area.

I purchased this product to clean the germs and air around the cat's litter box. The smell is gone and I have more peace of mind we a are no inhaling the dangerous germs. I have these Guardian's in four areas around my home and it really does smell cleaner.Definitely recommend this product for many applications around the home and office

Purchased this for our small home office. The air purifier plugs directly into the wall, rather than having a cord. It works well in this small space. Since it plugs directly into the wall, we can only put it in one spot, which is directly under a large window. I worry about one of my dogs knocking it loose from the outlet when they go to look out the window. Other than that, it works great for a small space.

I bought the air purifiers for my bedroom and living room. I can tell a difference in the air quality.

I purchased this to place in the bathroom to help with odors and mold. I’ve left it on 24/7 and do not see much difference in air quality so I am not sure if it’s working. I also placed it in the kitchen after cooking and did not notice a difference. I would skip this one and just buy the GermGuardian tower. Save your money.

Small, but pack an air cleaning punch. Fits neatly in your regular outlet and does what it does in place not quite right for a huge air purifier. I like to use it in the kitchen and bathroom. Only bad thing is it takes up both outlets.

Best air sanitizer I’ve ever purchased, we put one in spare room where we have cat litter and it’s really helped with odor control and we gave one to our daughter and she loves it! We had another more expensive brand we purchased from a TV shopping network that didn’t work as good as this one. I highly recommend you buy this!

This air sanitizer does work, but I only gave 4 stars due to the noise it makes

Small size, works well to reduce the odor near the cat litter box.

I love this product, we use it in our infants room and it makes the air smell so crisp and clean. There is a light plastic burn smell that emits from it when you first plug it in but it goes away within about 30 minutes with ours. I would definitely recommend this product to others. We are now investing in the bigger version of the Germ Guardian.

I bought this for my son's room and he's been using it constantly he's Allergies have gotten better his room smells better I give this to thumbs up and I would recommend anyone needing something like this to get this one it wasn't overpriced and it does a job really well

I first became aware of Germ Guardian products after taking my son to an urgent care clinic and they used a similar model in the rooms of their clinic. I bought three of these units to run in our bedrooms to offer a little protection from germs. Very easy to use, just plug it in and forget it.

Perfect for small rooms or areas. Germ guardian is such a good brand, I'm always satisfied with them. It's very quiet and sleek. Hardly even know it's on.
