This is a great little humidifier. I finally wore out the first one I bought of this last winter. It does a great job of keeping humidity in the air at a good level. My eyes are so dry and with winter heat I needed something to put some humidity in the air. My first one lasted for over 5 years. Excellent product at a reasonable price. Thank you Honeywel and Walmart for this product!

Best humidifier ever!

Best humidifier ever! I am so impressed with this humidifer. First off it is so quiet, i have purchased other humidifiers in the past and from the minute I turned them on they were horrendously noisy. I took this Honeywell Warm Mist Humidifier out the box today, made sure all the parts were in tntact, filled the resivoir with water then turned it on . I double checked to make sure it was working because it is so quiet.I highly recommend this product to any one looking for a humidifier.
