I have asthma and severe allergies. In a very short amount of time having this air purifier in my home, I have noticed such a difference in the air quality and my breathing issues. During the cold and flu season, this also provides peace of mind that our family is staying healthier with the nasty germs being taken care of in our home. With all of the air pollution, germs, mold, etc. that we breathe in every day, it’s nice knowing at least the air in my own personal space is cleaner!
