[Levoit ](https://pin.it/2MfulIFWT)or [Dreo](https://pin.it/2ChoGOPVn) are good. I've used both, no complaints
I just bought a Dreo one too! Really like it so far as well.
It hasn't leaked for me so far!
I bought a Dreo HM311S, and you can set an exact % for it to target, plus set schedules for different humidity levels or have it turn off at different time. I've found its accuracy to be within 2% of my other sensors, which is reasonable imo. It has an app, but I'm not aware of whether it connects to any larger smart home ecosystems. Frankly, I don't need it to so I haven't worried about it
Spending more IS frugal when it means a more reliable or effective or cleaner machine and better health or comfort. Just like using distilled water instead of tap in one is frugal despite the increased expense, depending on your local water. Money is not the only aspect of frugality. It’s right there in the sidebar. “It includes time, money, convenience, and many other factors.” If you spend more on a known good-quality humidifier, and decide it isn’t worth it, you can always resell it next season. Or return it within the window. Lowest cost approach? A simple small ultrasonic humidifier that you carry room to room with you and keep close, and a $2 plastic watering can by your kitchen sink to refill it. My mom has a $40 Dreo 4 liter that she shifts from bedroom to living room to craft room as needed. Keeps it half fullfor portability during the day. It’s lasted two winters so far. Don’t use tap if your water it hard though.
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..
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.
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.
My Dreo smart humidifier you can turn off both the light and the noise so not sure what you mean
I have a dreo too. It’s fine, wouldn’t mind if I found something better
