Pros: Filters air, reads out air quality with a small IR sensor on the back. Auto function is good particularly if your air quality fluctuates significantly over the day.
Cons: I've so far been unable to find replacement filters for sale, not that I need to replace them yet but another reviewer seems to be having issues.
Overall Review: I would recommend (especially if on sale), but be aware it may not last more than two years if you can find a replacement filter
