I suffer from allergies year-round, meaning there's always stuff in the air that makes me feel icky and gross. the moment I turned on this air purifier, my life changed. dramatic? yes. but still true. I no longer wake up feeling gross and weighted down by allergens, stuffy nose, sneezing and coughing. my head feels clear, as well as my air passageways. it's just the product I was in need of.
