I have had a Dreo 6L for a few years now and it works well. Very quiet. My house isnt overly dry so the 6L tank lasts a while. The hygrometer is fairly accurate so the auto setting works well - it won't turn your room into a steam room unless your settings are wrong
I have a small apartment with a combined l.r./kitchen and then a bedroom with the bathroom off the bedroom. I have a Dreo 6L. It's rated for a space much bigger than what I have. But I don't care. It is a warm/cool mist machine. I use warm mist. I like it. Because I have a deviated septum, I keep it at 65%. You can google adequate humidity for humans. If it's too dry, my left nostril clogs. With the humidifier I can breath clearly through both nostrils. I keep the machine next to my desk. I bought the demineralization filters that made for the Dreo. It clicks directly into where the water is filtered. It lasts for 40 gallons. I use a 1/2 gallon pitcher to refill. So I printed a sheet of paper with numbers and every time I refill it I x off a number so I know when to change it. I even run it in the summer because air conditioning removes moisture from the room (a/c is a dehumidifier) and makes the air dry. It uses a lot less in the summer. Now that it's cold and dry I am refilling a lot more. I don't get any white film on furniture. The machine stays fairly clean. For tight areas I use a qtip with a paper towel to wipe. All humidifiers I've had over my lifetime have hard to clean areas.
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.
I use a Dreo 6L humidifier for my studio that does cool/warm mist. Works great. Set it to 45-50% and refill when needed.
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.
I went through three WiFi enabled smart humidifiers (Govee, Dreo and Levoit) and I hated all of them. I assumed that because none of them had wicks and they were easy to clean and I was using only distilled water I would have no issues. I had terrible issues. I finally went back to my Honeywell HCM350B germ free cool mist humidifier I bought in 2019. I can toss the parts in the dishwasher to sanitize them, the wicks (use Honeywell brand wicks for no smell) last a while because I use distilled water and it has three modes - low, medium and high. If you want WiFi this is not for you. If you want lights and an app this is not for you. If you want to know the humidity in your room, this is definitely not for you. If you want an easy to clean and easy to fill humidifier for a small space that will last the rest of your life, buy this humidifier.
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.
