Pros: A Humidifier is a must have for the winter season on countries where you depende on the heater if you don't want to get that dry skin sensation and really want to be conformable at home. This $50 investment is one of the best you'll ever make to improve your lifestyle, and it can help you when you catch a cold either.

I always research and take my time before investing my money and the Optimus U31003 came as the best value. This unit it's great, good looking, silent, easy to refill and the 1.5 gallon tank lasts 24 hours on highest mist set up, so it can last even more on lower. We use it with some oil essence my wife got and the apartment smells very nice at all times (not sure if this will shorten the product life but is still worth it).

To get better results on small apartments, make sure you point the mist directly to the air return, that will make it flow through the entire unit and will make that 600 sp feet coverage even bigger.

I was kind of worried with the complains about the tank light but it isn't that noticeable even with all lights turned off and it actually gives it a better look.

Cons: n/a
