This air purifier is incredible for use indoors. I specifically use mine in my office given the amount of time I spend working from home these days, but this is also applicable in bedrooms, livings rooms, and really anywhere in your home that needs air purification. As for quality, I've been extremely impressed with how well this has helped my allergy symptoms. I suffer from sneezing, coughing, and scratchy throat and it's been a life-saver during the seasonal changes. Last but not least, this is VERY aesthetically pleasing too! Highly recommend!
