Worth the money!
I have purchased COUNTLESS different humidifies over the years. In the end I never really liked the ones I purchased and would only end up using them for a short amount of time. This one is very well made, the parts are sturdy not like some of the cheap plastic ones I had purchased previously. It is very user friendly, you can fill it up and turn it on and get it going right away. I feel the tank capacity is good sized for your average sized bedroom. I love that it has a display for the humidity instead of having to try and guess what the humidity of the room may be at. It is also quiet which is a huge plus for me as I don't like hearing the loud noise in my bedroom. It has a light function which I don't use as I prefer it dark in the room, but some people may enjoy that feature. I also found it easy to take apart and clean which is always a plus. I have noticed a huge improvement in the humidity level of the room since having purchased this. It is an absolute MUST in the dry cold winter to have something like this it has helped my sinuses a great deal.

Good capacity, easy to use, set a schedule from the app, this is my second purchase and I love it
I purchased this LEVOIT Humidifiers for Bedroom Large Room Home because I already had one from last winter and absolutely LOVE it. It is so quiet and it has so many great features, especially operating it from the app and setting up a schedule to turn on and off. I set mine to turn on every night at 10:00 p.m. and turn off at 6:00 a.m. It is very quiet and it provides a cool mist. This has helped me so much this winter with keeping my sinuses from drying out due to having the heat on. I use BestAir 3BT-PDQ-6 Original BT Humidifier Bacteriostatic Water Treatment in my units to keep the units clean and from getting funky. I put three capfuls in the water tank each time I fill the tank with water. This has also helped my older humidifier unit and it's staying clean and not getting any type of funk or buildup. I have to fill with water about every 2-3 days. I have had zero trouble with my older unit which is why I chose to purchase another just like it. It's a good, manageable size and really easy to use.

Perfect humidifier
Perfect humidifier for a regular sized room; works great in the bedroom, struggled a bit to keep up with my living room with tall ceilings. Using it in the bedroom, the water tank lasts 2-3 days without needing to be refilled (this is also during winter when the air is dry). The one in my living room needs to be refilled every day. The panel light is a bit bright for sleeping but using the night mode is wonderful. Cleaning the tank is an absolute breeze. Also, since it’s top loading, it’s very convenient to refill it using a pitcher rather than having to carry the whole tank back and forth like with other models.

Great humidifier, difficult to clean.
I like the design, functionality, ease of set up, and the durability. It does a great job for sure. Cleaning it on the other hand can be somewhat of a challenge.it does require a lot of distilled white vinegar. And, if you are using distilled water, great, it will definitely not be as hard to clean, BUT, if decide to use tap word to save money the filter will be gross and dirty in no time. I already ordered a 30 pack of replacement filters for it. They were decently priced and the work well with it. You definitely have to clean the equipment more often when using tap water. It is still a very good product.

Quiet & works great!
This humidifier works great! I bought it for our living area to cut down on static, but more so for my plants! I love that you can see the humidity level in the room and can set it to run until it hits a certain level. It has a nightlight you can use and you’re able to shut the display off if it’s too bright in your bedroom. It has a large tank that can withstand running all day without running out. It is super quiet and can really put out the mist, if needed. My favorite part is probably the app! I love being able to control it from my phone! In the app, you have the ability to add all of the plants you have and it will tell you ideal levels of humidity and basic care reminders. It’s great!

Humidifier and App easy to set up. Nice unit.
It is very nice. Has been working excellent for the couple days I’ve had it. Humidity stays very close to where it is set and the app on the phone is handy and easy to operate. It’s a nice size, sturdy, was easy to set up. I like the settings for the mist and the nozzle to direct it. Very happy with this humidifier. Glad I went with a sturdier one with the app and top fill.

Your happiness is guaranteed
I bought this humidifier in January, 2023. It was everything you would expect of a humidifier - it is super quiet - it puts out a lot of moisture - it doesn't' deposit moisture on nearby furniture - the app is easy to program - you can schedule any function from the app. That is, until the unit won't work after a power outage. So why the 5-star review of a unit that unexpected dies after a total of maybe 9 months of usage over a 3 year period? I didn't purchase the 3-year extended warranty, so the best I could hope for was getting help for some magical sequence of button pushes that would reset everything. I contacted Levoit and they quickly responded and after reviewing a short video I provided of the unit not working, they suggested an additional way of resetting the electronics beyond what is described in the user manual. That didn't work, but still I am happy. Why? After trying all know ways to reset the unit, I notified Levoit that the unit was dead, and they offered to send me a brand new replacement. How's that for customer service! Here is what Rufus says about the warranty: "The LEVOIT Classic 300S Humidifier comes with a Satisfaction Guaranteed warranty. If your product is defective, LEVOIT's California-based Customer Support Team will send you a replacement right away without requiring you to ship it back. For additional coverage, you can purchase an extended warranty through Amazon to extend protection up to 3 years if you'd like extra peace of mind." They take "Satisfaction Guaranteed" seriously. Warranty expired. No extended warranty. Customer not thrilled that unit cannot survive a power outage. New unit on the way. That, boys and girls, is how you crush the competition and win customers for life.

Buying distilled water can add up but its worth it and I dont' have to clean it often.
Excellent humidifier – I don’t know why I waited so long I absolutely love LEVOIT products, and this humidifier is no exception. I’ve purchased three LEVOIT humidifiers in the past two weeks, and all of them have been working flawlessly. Setup was quick and easy, the top-fill design is very convenient, and cleaning and assembling the unit is straightforward. The app is a big plus—it’s easy to control and gives you more useful information than just basic humidity readings, which I really appreciate. Before using these humidifiers, the humidity in our house was around 25%, which is very dry and unhealthy. Since adding one to our bedroom, I sleep noticeably better, wake up without headaches, and no longer have a dry nose or mouth in the morning. As a bonus, our plants in the basement are loving it too—no more curling leaves, brown edges, or leaves falling off. Overall, I’m extremely happy with this purchase and honestly don’t know why I waited so long. Strongly recommend LEVOIT if you’re looking for a reliable, well-designed humidifier.
