I love my dog, scattered diffusers, candles, & wall plug-ins, but with a number of scents accumulated in my small bubble - I’ve developed serious allergies. After using the humidifier for a few weeks, I’ve noticed a significant change in my day to day cycle. I do not wake up feeling congested in the middle of the night & early morning. My face has also been less puffy due to congestion & dry air. I am not saying that I look forward to using it when if and when I have the flu/common cold, but if my daily allergy symptoms are improving in the summer, I know for a fact that the Crane humidifier will 100% take care of me!
