I have been looking for a quilty purifier that actually works, for a decent price and multiple benefits. Living in the country and the constant rain lately and being a pet Mom, unfortunately my home is musty and the air quality hasn't been the best and my son has developed allergies and I needed to try to help with everything and this machine does it! The multiple settings, it's not bulky and it fits in the corner and I have noticed the air in my home seems much cleaner, less musty and my son's allergies have been better. This is honestly a life saver and we have purchased a second one! If you're dealing with any issues like I am I highly suggest this, great, price quality and effectiveness!
