Disclaimer I received this product for free in exchange for a review however the opinion in this review is my own based on my experience with the air purifier. 

I have  a hybrid work location with it being split between in office and working from home. This is perfect for my desk cubicle at work. It's very compact to put in my backpack to bring to the office and not take up much room on my desk. On low settings it is super quiet my cubicle neighbor can't even hear it.  On a full charge I've gotten 2 full work days on low settings.  Even on high the noise is not obnoxious I've fallen asleep with it easily with it on my nightstand.
