Model 400

I have this whole-house unit installed in my forced air furnace: [https://www.aprilaire.com/whole-house-products/humidifier/model-400](https://www.aprilaire.com/whole-house-products/humidifier/model-400) In 2015 it cost me $816.50 to have it installed (I'm in Pennsylvania) - including parts and labor. So maybe estimate $1100 today. We turn it on with a fresh filter, usually in December, and it runs on automatic through the winter. I should change out the filter at least once in the winter but I usually don't. We turn it off in March/April.

With that level of guitar, I would recommend investing a bit more and look into humidifying the room your guitars are in or humidifying your whole house. That way, you can leave your guitar out on a stand or hanging on the wall, and you get the added benefit of making your house much more comfortable. My house is \~1200 sq ft, and [this humidifier](https://www.homedepot.com/p/AIRCARE-VALIANT-Gal-Cool-Mist-Evaporative-Whole-House-Humidifier-for-4-000-sq-ft-Brushed-Nickel-HD1409/204364015) is capable of keeping the whole house at 45% (though I do need to fill it more often in the winter months). You would fill it much less often if you're just keeping a single room humidified. The other thing to look into is a [humidifier that plug into your furnace](https://www.homedepot.com/p/AprilAire-Model-400-m-Water-Saver-17-Gal-for-up-to-5-000-sq-ft-Whole-House-Evaporative-Humidifier-With-Manual-Control-400M/312148211). These are great because, once the initial water line is run and the humidifier is installed, you don't have to worry about refilling. It's literally a set it and forget it solution.

Just get an aprilaire 400. They work fine for that size house.

My Aprilaire 400 works just fine with cold water. My windows sweat if it's set too high.

If you own your own home, get the AprilAire that attaches to your furnace. Idk how much they cost but it would be cheapest in the long run.

If you want whole-house coverage, Aprilaire units connect to your HVAC and are the gold standard for set-it-and-forget-it. No daily maintenance, just annual checkups.

I have a whole house humidifier on my HVAC and it's struggling. It's been incredibly dry lately.

We have an Aprilaire unit attached to the HVAC trunk in our utility room. We shut it off as soon as it gets to the Springtime so no issues with mold. 

I had Eric from Valin’s heating and air install for me a AprilAire version and honestly it was the best thing I did! He explained to me all my options, it really really made a difference in my house. If you need his phone and wanted to ask 703-239-3633, Valinshvac.com. Hope that can help

Aprilaire makes solid dependable equipment. Had one for 3 years w/o issue

If you have central heating and air I HIGHLY recommend looking into a central humidifier especially if you are in a very dry area. Set and forget with auto water feeding and humidity setting with minimal (like 1x a year) maintenance. They are usually not super expensive to install either. I like the Aprilaire units.

Aprilaire whole home system is the way to go…

Mines worked flawless with basic maintenance for 5 years strong so🤷‍♂️

And no one cut any wires, it was an easy install along with a new blower and heating coil being installed at that same time.
