I live in Minnesota and recently the air quality got worse since there are forest fires next to the Canadian border. This Shark Air Purifier unit gives you more than an average home air purifier. It's not just high performance up to 1200 sq ft, smart technology, real HEPA filter and so on. It is a quiet, powerful and well designed unit. I recommend it for every household especially if you are sensitive to the air quality in your living space.
