Very quiet, moves a lot of air
This air purifier moves a lot of air. Setting it on auto adjusts the fan speed based on how 'dirty' the air is in the room. I'm not sure how the sensor works to determine air quality, but in my room it always shows around 10 and so it keeps the fan on setting one. I always forget that it's even running, plus the lights shut off after a few seconds making it even harder to tell if it's running. For me personally, I can't tell a difference in the air quality with it compared to without it. So is it actually doing anything? Well it is pulling air through the filter so it must be doing something. It's extremely lightweight and very easy to accidentally knock it over and the plastic does seem like it's cheap. I've also added lots of essential oil to the pad on top, but I can never smell it.<br /><br />Pros-<br />It has to be filtering the air, at least somewhat.<br />Super quiet and lightweight.<br />Particle sensor to auto adjust the fan speed.<br />Comes with a filter.<br />Lights shut off after a few seconds, making it ideal for a bedroom.<br /><br />Cons-<br />Feels cheap for the price.<br />Essential oil pad seems pointless, the bottom is solid plastic and I don't see how air would pass over it.<br />Either the particle sensor is a gimmick, or I just have really clean air in my entire home. I'm not sure on that one.<br /><br />Overall for the price I can't really recommend this unit. There are much cheaper options that do the same as this unit just without the sensor and auto adjust function.
