Please keep selling this make and model!!!

This particular make and model of 1.5 gallon warm mist is the best we've owned in recent years. The newer version, quite frankly stinks. The controls on this one are reliable. The electronic controls on the newer one work sporadically and ultimately break quickly.

This humidifier best suits my needs. I've tried many other humidifiers through the years. I love the warm air mist. It helps me feel warmer in my home which I keep at 68 degrees in the winter. This is the 2nd Honeywell 1.5 gal. ********* sq ft Filter Free Warm Mist Humidifier with Essential Oil Cup that I have purchased.

Easy setup, Simple to use with Great Results

I've been really happy with this Honeywell humidifier. It's easy to set up, simple to adjust, and it makes a noticeable difference in dryness—especially overnight. It runs quietly enough that it doesn't disturb sleep, and the tank is straightforward to refill and clean. After a few days, my room felt more comfortable and I woke up with less dry throat and congestion. Overall, it's a solid, reliable humidifier that does exactly what it's supposed to do.
