Yes irnea8, that's the one. It may cost a bit more, but I'm hoping it lasts longer too with the stainless steel. It has no smaller tubes for the humidifier to go through.
I'm super cautious with it as I don't want to have a relapse. So I turn it on and leave the room, even shutting the door. There's hardly a visible steam coming from it, but the size of the drops make a difference too and I don't know if what comes out is a good size for those of us with NTM. It does actually humidify a couple of rooms even with the door closed. I suppose it goes under the door as it isn't tight to the floor?
I'm sensitive to lack of humidity and know when it gets below 40, my mouth starting to get dry. the inexpensive thermometer hygrometer I have in another room confirms the moisture in the rooms. I'll turn it on if it's under 40. I have it in my bedroom, so at bed time, it gets turned off and so far, I haven't woken up with dry mouth. I'd rather the moisture settle before I linger long where I have it as I know it is with caution that they should be used.
I've only had it for a couple of months, I just couldn't stand another winter being so dry in the house. I like it however and works well for me. Hope that helps!
