Product review (5 stars): AWESOME!!!
I've had an excellent experience with my Essick humidifier.  I purchased it 15 yrs ago and it is still running strong.  I live in the desert AND have hard H2O  I change my filter every 3 mos at least.  I sleep better with the moist air, not to mention what moisture does for your skin.  I also have an ultrasonic humidifier next to me on my night stand, so I really reap the benefits of clear sinuses AND moisturized skin.  Thank you Essick!  I love this product!  Anyone living in the southwest should have one in their bedroom and major living space.
