Honeywell - HE300A1005/U (TrueEASE Advanced Fan-Powered Evaporative Humidifier)

If you have a forced air HVAC then get one for the whole house. Change the filter twice a year. We have the Honeywell He300 and it uses a filter cartridge. Have had ones like it for 25 years. Stay away from the drum ones.

Both April Aire and Honeywell work fine pick whichever fits your setup better. Main thing is your electrical steam units need more juice so check if your transformer and wiring can handle it before you start. Make sure there's a shutoff on the water line or add one. Taking the old one out without screwing up the ducts is the worst part so just take it slow there. Steam to steam swap isn't too bad though follow the instructions and don't rush it.

Came here to say just this! Evaporative is the best for humidifying and healthier air. We also have a Honeywell evaporative hunidifier… it is easy to clean and really helps keep the air moistened without spreading unhealthy mold particles, like my old cool mist humidifiers did.

How big is the room? I use an evaporative Honeywell. It does well on the lowest setting and I only have to fill it about once a day

I would likely recommend an evaporative humidifier, not a warm mist one. The mist ones have a lot of problems, such as being more prone to bacteria growth and harder to clean. They also try to add more moisture than the air can actually hold, resulting in mineral condensation (white dust) appearing everywhere over time, especially if you have hard water. Aircare makes a decent console-style evap humidifier with a decent tank size and is pretty easy to clean. I used one for years until we moved to a house with a humidifier on the furnace. Now I use a smaller Honeywell evaporative humidifier upstairs only. It gets filled each evening, runs constantly all winter, and cleaned each weekend. I went through about half a dozen of those warm mist ones before converting. It didn't matter the brand, how much I treated the water of cleaned them, they were all pieces of junk that lasted only 1-2 years. Crane ones were probably the worst.

Nothing on the carpet. I kept it on a plastic tub lid, just in case but never found water. The Honeywell one i just put on a dresser. Never used one with an air purifier. I wouldn't put them next to each other since they are both ducking in air, but I dont think there would be problems

We got the Honeywell one because we already had one and it seemed better to only have to buy one kind of filter.
