i have 2 of these units and bought 2 more. they run quiet and boost humidity very well in the house. they have no filters to replace. when they shut off due to salt build up from my water, i just put in some vinegar and let it set for a while. dump out the vinegar and refill with water and they are goid as new. i run mine constantly and only clean them every 2 weeks.

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.

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.
