This is small and mighty! It works well and the small lets you take it where you need it - home, work, travel. I used this on our vacation when you never know if your hotel might feel musty or uncomfortable. We had air quality alerts (due to wildfires) when I received this so it was great to have in the house as added protection. 

My son has seasonal allergies and this was great to move to his room at night. The compact design makes it easy to move around as needed. 

I did receive this air purifier for free in exchange for an honest review.
