Aprilaire - 866 Modulating Steam Humidifier with Model 850 Fan Pack

We live in Zone 6a and installed this standalone [whole home humidifier](https://www.supplyhouse.com/Aprilaire-866-Modulating-Steam-Humidifier-w-Model-850-Fan-Pack) in our basement with a fan that forces the “cloud” into our living room, directly above. It’s supposed to run off of a humidistat but my husband has it plugged into our Home Assistant which pulls from sensors across the home that include humidity. Only trouble we’ve experienced is that sometimes our walls in the living room start “crying” (too much humidity). Our first winter in the home, we were suffering a painful 15% humidity and constantly were refilling humidifiers in our bedroom and living room. Since installing, has been much more comfortable but being we live in an old leaky house with a lot of wood, the humidity often dissipates quickly. ETA: we live in a 3-story four square, rather large in square footage, with water radiator heat in all rooms and a high velocity air conditioning system that we run just the fans sporadically through the winter to circulate air.

We are planning to get an Aprilaire whole house steam humidifier. There’s an option to get a small fan box that gets installed inside the wall and it looks like a white air vent. The fan runs with the steam humidifier to distribute when you can’t have a humidifier in line with HVAC. We have a boiler so can’t add that to it and use about 5-10 gallons of reverse osmosis water a day with ultrasonic humidifiers. The steam system can humidify 35 gallons a day if connected to a 240V connection and the salt from our water softener doesn’t need removed by RO.

I have a century house in NEOhio, and the only fix has been an Aprilaire steam humidifier. It does work and maintains humidity level, BUT it will use some power! The canister I change once a year for about $85 bucks.

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.

This! We bought ours on Amazon as an open box and saved a few bucks. We have a friend who works in hvac that helped to install it. 

Get a quote from Buric! They did our HVAC replacement a few years ago and we added an AprilAire humidifier at that time. They were great and other family have used them since and also had good things to say.
