So for the last several weeks, I have been experiencing the negative effects of dry air in my home, particularly in my bedroom. My nose has been dry and sore with inflamed nasal passages along with my nose running "like a sugar tree" . Sleeping with a fan as I have done for the past 15+ years became impossible. I don't know about you, but that combination makes for a miserable sleep. Anywho, I had never needed or used a humidifier until this purchase. Let's just say that my dreams have returned and I'm waking up to a nice mist rather than a pillow of Kleenex and a sore nose. Life is good.After researching and reading reviews of several products, I settled on this Ultrasonic model and I couldn't be happier with my choice. It's a simple setup - add water, plug in and select low or high speed (both give the option of turning the blue light on or off).The Ultrasonic is whisper quiet with the occasional echo of water, not dripping, but a soft cascade as if it were a mini water fall. I find it rather soothing, a bit of "white noise" which is good because I haven't plugged my fan back in as yet. The water reservoir is easy to fill (I use distilled water) and it's ready to go. The mist is cool, not overpowering and not "smoky" and you can turn the nozzle into the desired direction.Ok, there you have it! I'm Happy and a bit Sleepy now!
