I bought this because of the wildfire smoke that recently happened all along the west coast. 
What I can say about the product is that it was fairly quiet. Seemed to do a decent job at keeping particles at bay. 
The cons were that and it may just be user error, but when you pushed the power it didn’t turn off. You have to unplug it. 
Also the filter fits pretty loose inside which I thought odd. 
Pros were I guess there’s a section for essential oils I didn’t see it as I only bought it for the air purifier part.
Gets about a medium size room and a decent price. Although I paid 40 for expedited shipping. 
All in all, ok.
