I was surprising at the time when I am opening the package, it was way smaller than what i am expecting, and i was planning to use this at my shop and now ending use it at my house. This thing very tiny and makes a little noise when it is on, but I put it in the bathroom to get rid off my son's diaper garbage can smell, and it seems to start working kills the smell a bit, and now i am smell the odor when i opening the diaper garbage can, and most of the time no more strong odor smell. So I am need to look something bigger for my shop.

It is a small air purifier, very small. Size is like two tea cup add up together. It can be powered by 4 AA battery, which make it portable, and can be carried around. This purifier does make a little noise; however, the the noise is very low. I have sit close to it to notify the noise. The small air purifier works!!! There is clean air come out from the purifier. The air come out from the machine smell like the air after the rain or a thunder storm, very flesh. I let the purifier run over night in the sitting room; and I can smell the fresh air around 8 feet to the purifier. I think it works very well. It is a good little air purifier for my house after a long winter.

like many reviewers has said i was definitely surprised by the size. I own several air purifiers ranging from desk models to room models. this is probability 1/3 the size of my desk purifiers so i was a little reserved about how it might perform. But to my surprise it functioned just as good as the bigger ones, i feel like odd smells/odor got filtered out quite nicely and did a good job.

This little air cleaner keeps the air in room clean! I have pollen allergies so it is very important for me to have this in my house to keep the air clean and without pollen!!! I tried this and it is really good along with the good quality it has!!!

Works good.i put in the bathroom to elimanate odors.its small but works great !!
