I have 2 dreoo 8l and its so cold out now that they are not going above 40% running on high on a 800 sf apt.

I got the dreo 8L off of amazonfor around $100. It is very quiet even on high. It will last around 2 days in the living room. In the bedroom with the door closed it will last 5 days running all the time. It has a light on it as a nightlight, but it can be shut off. It has a wifi app. So you can set it to run when you want. It has a automatic mode that it will shut down when it reaches your desired humidity. First one I had has was a evaporative humidifier, it worked good but was really loud on high. Mist humidifiers or ok if you have clean city water, but if you are using well water they make a white ash dust that people don't like. I've never had that problem with my city water. This is my third one, the main problem is they leak if not cleaned often, and sometimes the float gets stuck for no reason. This only applies to the type where the tank is above the electronics. It's happened on all three I've owned even with cleaning every week with city water. I ended up putting the humidifier in a clear plastic storage box with high sides and put a water alarm in the bottom of the pan. I got rid of the first two after they leaked, I thought they were just cheap , so the third one I spent more on. Apparently it's just the way they are because the expensive one leaked too. Luckily I like on a first floor, so the only damage was a wet floor. If I was on the second floor it probably would have done thousands in damage. It took a while for the carpet to dry out after 2 gallons spilled.

I was very very happy with the Boneco S450 for about 9 years. It uses actual boiled steam and a demineralization pad which bobs around the boiler plate. I would use Boneco cleaner which is essentially powdered CLR each year before storage. Then I went to replace it. It still worked, but I just wanted a refresh. And found it was removed from the U.S. market. So, it being long in the tooth, I decided to disontinue use and keep it dry in storage as a backup. After several false starts, returns, and wasted money, I settled on the Dreo 8 liter. It is high capacity, has an available demineralization cartridge, and, although a very similar design as the Levoit, is not prone to becoming water logged and leaking upon startup. I have never had the Dreo leak. It is also wifi capable.

Any "mist" model will do this. It's suspending water droplets in the air via ultrasonic excitement, which is not the same thing as steam. "warm mist" is close to steam. Honeywell does make a steam model. I haven't had any issues with the Dreo since leaving it on level 1 warm mist.

I bought a Canopy, without realizing how gamed the marketing is in this sector. It was essentially a paper filter tower dipped in a reservior of water with a computer fan drawing air through the filter. It worked, but the construction was dead simple for being over $200. And required a new filter every few weeks. And of course, it had a noticeable cooling effect. Then, I bought a Levoit with warm mist option. It had a design flaw where it was very easy to water log the boiler, which caused flooding. I then tried a Dreo and so far so good. It also has a heat option.

I have Dreo humidifiers, and my plants love them. I have both the 6L and 8L models. I run them at 65% humidity, and they run for 12+ hours without running out of water. I would recommend staying away from no-name humidifiers. I fell into that trap last year and bought several inexpensive ones online. Every single one failed within the year, and began leaving puddles where they were sitting. The other issue with cheap humidifiers is that they often can be cleaned properly, which will eventually lead to mold issues in the unit, if they last that long.

If you want a warm mist humidifier than I really like the new DREO 2-gallon (8L) humidifier. I can change the setting on my phone with the app, it really is a warm mist and holds 2 gallons of water, so I don't worry about running out when I am in the office. I have it on the auto setting and haven't had any issues. This does need to be cleaned regularly with vinegar due to scaling from minerals in the water. If you don't want or need the warm mist that I like the vornado Evaporative Humidifier evap 40. It works, holds 2 gallons of water. Just change the wick filter every few weeks and I am good to go.

I got the DREO 8L cool & warm mist humidifier for my bedroom. I like the near 2-gallon tank. I set mine to auto and so far, it is working well. I like the app. I also have a FOHERE cool & warm mist humidifier. it has a 6L tank, no app but it's also doing a good job in my at home office. I set it on auto and just keep water in it. Hope this helps. I got mine from Amazon.

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

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.
