The Germ Guardian does a great job. I have inside cats, and even premium litter creates some dust, so I decided to try the room plugin to see if it could tame the litter scent carried by the dust. To my great relief, the Germ Guardian is doing just that. It runs quietly but does a great job of keeping the scent of the litter from becoming overpowering. All of us, including the cats, are no longer sneezing from the litter scent.

Works well and is quiet. Have not used these much yet, but I've used at work cubicle, no one notices it's behind my monitor. I love the rotatable plug so it fits with other items that are plugged in to the outlet or power strip. I plan to use in my room when traveling, it does not weigh much so it should be easy to pack.

We've used our sanitizer for a few weeks now. It's hard to know if it's killing germs because we have been extremely careful with the COVID situation. That said, my son noticed a difference in the air almost immediately. This is significant because he has Anosmia (no sense of smell), but he said the air FELT like that of a breezy day outdoors. That observation leads me to believe that the sanitizer is doing what it's meant to do. He is a teacher, and when he gets back to his classroom, a sanitizer will be going with him, too!

What a difference the germ guardian has made in the house! Clean fresh air indoors and no odors. I had purchased four 2 for downstairs and 2 for upstairs, amazing!

I have seen larger versions of these in hospitals and didn't know what they were. After reading about UVC I couldn't order soon enough! We keep one where the cat's litter is and one in our bedroom. Didn't know what we were missing.

Works well in small rooms . Use in my camper when it is in storage. No musty smell in the spring. Bulbs need replaced yearly. My old units were over 5 years old.

Just plugged one in my hall way. Not whisper quiet. There is a hum, but not too much of an issue. Might be an issue if in a bedroom with a very light sleeper.

I bought this and it said quiet I hear it at the other end of my home. Have no idea if it actually is doing anything and it serves as a small night lite

We weren't happy our previous plug in air purifiers worked amazingly, this doesn't seem to do anything but light up. The air doesn't smell cleaner and still a lot of dust. We are sneezing and coughing as much as before using it. I am returning these and purchasing my old brand. Cost more but they were worth it. Our house is only 930 square feet and having bought 4 I'd have thought they'd be effective.

I plugged in the 2 in a pack in a small front office. There is light and fan is working. But I came back in the morning, the smell is the same. It does not change anything in the room.
