I'm looking for the most efficient way to raise humidity in my home in MetroWest MA during winter.  I am sick of refilling and cleaning standard humidifiers and I have to run two big ones to keep up in my 2,300 sf home.  I spend a lot of time filling them in the colder 6 months of the year.  If I don't do anything then the humidity gets in the low teens sometimes and our sinuses/airways/skin gets really dry and uncomfortable.  I was debating a wall-mount whole home humidifier like the Aprilaire 360 (we have baseboard heat) or getting an air exchanger.  I know air exchangers are sometimes used to lower indoor humidity but in an area where it tends to be humid outside, would the opposite be true?  The air exchanger has the added benefit of bringing fresh air in, reducing dust in the house (I think) and reducing odors from cooking etc. (we don't have a good place for a kitchen exhaust). I'm interested in the thoughts of people in this group.  Thank you

Also, I'm not sure if "Air Exchanger" is the correct term. It might be "Heat Exchanger"...

I use a $20 ultra sonic mist maker off amazon to do our house. We have heated floor and like you said get tired of cleaning units. I have a float fill a plastic bin with the mister in it. The mister usually lasts on year and I use a new on the next year.

Buy the single head misters....that way you can just throw them out when they break, I tried to change the disks but that didn't work.

Interesting idea.  I didn't know you could use a mister for that.  However, I know float switches as being unreliable so I'd be concerned about a flood if the float switch failed.  Especially due to all the work I put into installing hardwood floors throughout my house...  Cool idea, though

Agree, mine is in basement. If you put a valve in the line and only open it enough for what the mister uses then the float switch is the safety that shuts it off to help prevent floods. But I wouldn't place on hardwood floor either. Good Luck...
