Pros: Looks nice and functions fine. It was easy to assemble.

Cons: Using the fan, sterilizer, and anion features, everything is fine. I can't really notice a difference, but air is definitely moving. When you turn on the purify feature, the air has a foul odor - like a strange chemical smell, or almost even fish. Hopefully there are still benefits to the filter without using the purify feature. When I ordered, I had the wrong shipping delivery, so I had to cancel the order and re-order it. It worked fine, but when I contacted the seller to make sure my pending credit card transaction on the canceled order was straightened out, the customer service rep did not understand what was going on. They had order numbers messed up and we were talking past each other the whole time. Luckily it resolved itself.
