I bought a Venta Air Washer (humidifier) to help keep the humidity up now that the colder weather is here and the heat is on (15 degrees outside this morning!).

Last year I tried an ultra-sonic humidifier, but since we have so many minerals in our well water, it left a fine white dust on furniture. It also was not big enough to keep the humidity level in the 40’s. Often the humidity level fell to low 20’s or even high teens. I did use a Dampit in my fiddle to help keep it humidified.
This humidifier is rated for 800 square feet, so I have it outside my office (where I practice) in the hallway so it can also humidify my bedroom and den. The humidity level has been pretty steady at about 40. Not ideal, but much better than last year. I’ll keep an eye on it as we get further into the winter. I may have to buy a smaller unit just for my office, especially now since I have two fiddles.
