I purchased this product in December and I must say it’s one of the best humidifiers that I have used so far. The cleaning iis very easy and the unit itself is very quiet upon operating. I am very pleased with my product and the air quality difference is insane! The customer service representative Scott was very helpful and offered me a free filter to replace the current one that I have. I was very pleased with his exceptional customer service, and I would like to extend my thanks again to Scott for his professionalism for being very courteous/ attentive with assisting me with the instructions on using this product . I highly recommend this product!
