Pros: -design and energy star

Cons: -after unpacking and plugged in, this air purifier starts to unleash a very unpleasant smell, like plastic mixed with chemical compound, have to open it in bathroom with open windows for a night to solve this issue.

- the black pre-filter and white filter have no position lock or position holder, you just put it up, it just make people feel cheap

-sometimes the ion button is not working, even though you cleaned the machine as directed by owner's manual.

Other Thoughts: Just buy American brands, japanese brand like this overcharge the price and give you half what American machine can do.

Pros: Love this thing. I bought one after reading the reviews. I have dust mite allergies.

Seems to provide a crisp, clean smelling air. It seems to help with my sinuses.

Absolutely quiet at the lowest setting from a few feet away. At medium setting, it is like someone whispering at a few feet away.

Bought one for my parents after I bought one for myself. Has a 0.3 µm filter. If you have allergies, I recommend this product (Note: It is possible that if you have an old carpet which produces a lot of dust or you constantly leave your windows open, the rate at which you bring in dust and allergies may be much faster than the rate at which your air-purifier can do its job).

Cons: Somewhat large footprint. A bit pricey, so, I bought it during the black Friday sale. I bought my 2nd one at another popular website for cheaper.
