I’ve been using [this](https://x.com/BestDealRadar/status/2012175998192693442) Dreo humidifier for a while now and it’s honestly been one of the easier ones to live with. It’s quiet enough to run all night, actually raises the humidity without leaving puddles, and the self-cleaning part helps a lot with maintenance (which was my biggest issue with past ones). I also haven’t noticed any white dust so far. It’s not perfect, but it’s the first humidifier I didn’t give up on after a few weeks.

I have a couple DREO that I like a lot. One is a big 2.9 Gal and another that’s 1 Gal. They’re WiFi enabled so I get notifications when they run dry. They also have humidistats so I can set my desired humidity level and not worry about it getting too high and causing mold etc..

we have a dreo stand alone... Works great but you need distilled water, otherwise all of them will clock up in a heart beat. They do work, but you have to be aware of your house insulation situation...the more you have humidity, the higher are the odds of accidental dew point issues on walls etc...causing mold

I’ve been using a dreo cool mist smart humidifier for a couple years and I really like it. The directions do say it can be used with tap water but it works much better with distilled water. I’ve been using distilled water and I only have to clean it once per week with a quick rinse with vinegar. No scale build up and no mold. It still looks brand new. I got tired of buying distilled water so I did buy a water distiller. It’s super easy to make distilled water and I can store a week’s worth in glass jars and then just fill the humidifier up as needed. Otherwise I would have to buy 10 gallons of distilled water per week. The Dreo humidifier is nice because it measures the humidity in the room and turns off when it is optimal so I don’t have to think about it. It also tells me when to change the cartridge.

Purchased a new Dreo ultrasonic off of Amazon. It has a setting to dial in preferred humidity and will adjust output as needed. It keeps my 2000 sq/ft home around 40% despite lots of heat use and very dry air. I do recommend one.

Shit. Help a brother out. What do you think of this one? https://a.co/d/aJ0oFfT Just started using it. Has made a huge impact but don’t want to end up breathing mold in a few weeks.

Last month I bought both a levoit and a dreo. What really annoys me is that there seems to be no device that does neither a sound nor a bright light at startup which makes it really difficult to use automations when used in the bedroom. Apart from that I can recommend both as both integrations do their job.

With my dreo you can turn off the ambient light too. But if you power it off and on again, it lights up for a second, totally blinding everyone in the bedroom. It's not a problem when both are asleep but it's a problem for me since I control the power status with a door sensor.
