This humidifier has made a noticeable difference for me. The air feels less dry, and my nose and throat feel much more comfortable, especially in the morning. It runs quietly and works well through the night. It’s simple to set up, easy to refill, and doesn’t leak. I like the clean design and how consistent the mist output is. For the price, this has been a great buy and I would definitely recommend it. Read more

I am absolutely thrilled with my new Classic 300S Humidifier! Not only has it made a remarkable difference in the air quality and comfort of the bedroom. In addition, the entire experience, particularly with their customer service, was truly outstanding. 💨 The Humidifier Itself The Classic 300S is solid. It's quiet, has a sleek design that blends seamlessly with the decor, and the top-fill feature makes refilling a breeze. The mist output is impressive, and the automatic shut-off gives me peace of mind. It holds enough water to run all night and often well into the next day without needing attention. It's clear this is a high-quality, durable appliance. 📞 Phenomenal Customer Service What really sets this purchase apart, though, was the phenomenal customer service. The response time was quick, and the care they showed demonstrated a genuine commitment to their customers. In an age where good customer support is rare, their team knocked it out of the park. It truly solidified my trust in the brand. Highly recommend the Classic 300S for anyone needing a reliable, effective, and beautifully designed humidifier. You're not just buying a great product; you're also buying into a company with incredible support! Read more

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. Read more

This is my 2nd 300S humidifier. First one stopped working soon after the warranty ran out. Good customer service. Bought an extended Amazon warranty to give us 3 years of protection this time around. It works really good when programming a weekly schedule. I programmed it to operate nightly as we sleep. Gets really dry here in the winter because of the forced air heating. I have an Aprilaire system on my furnace but never worked. Not a fan of all the cleaning required to keep it running properly even with using my Reverse Osmosis water. A nice looking well made humidifier for a single room. Easy setup with app to your WiFi. Little to no noise during operation, a fair price. Read more

UPDATE: How many times do my hopes have to be dashed by humidifiers???!!! I am sick and tired of it. This one’s humidity output is very very poor! (I followed all company guidelines.) I woke up with dry nose, skin, etc. as if I hadn’t even had a humidifier…near my bed!! Yes, it is quiet so that’s a big plus. BTW: get a humidifier that does NOT require distilled water! What a royal pain….about a gallon every day. Ridiculous. At that rate I’d need an entire closet for only distilled water!! PS: Next time I will only review after I’ve had the product for a while!!!! Original review: Eureka! Finally a humidifier that is quiet, has great output, works well. If you get this, and you should, download the App which is simple and makes using the machine very easy and you get terrific info like mist/humidity level, etc. I messed around with a bunch of humidifiers and got so frustrated!!! Go with this one. It’s excellent. PS: I only use distilled water and I use it in bedroom. Does not make any noise!!!! Read more

Our apartment is always dry in the winter so running humidifiers in each room is essential to keep from having dry skin, bloody noses, and coughs. (it is also beneficial to all my plants!). We have used several different types of humidifiers from several different manufacturers. We have found the Levoit humidifiers to be the best and keeping our rooms above 45% and are easy to use and more importantly, to clean! This particular model is my favorite because it can be controlled from my phone and also has automatic features to control the humidity levels to keep the room at a comfortable level. Cleaning is also easy - We use vinegar, water and dish soap to keep the film that collects inside the tank at bay. We have hard water so often there is a crusty residue in the base. To help with this, we purchase small water filters here on Amazon https://amzn.to/3K1aYWg (shaped like goldfish!) placed inside the tank to filter the water a bit and reduce the nasty film. We also use filtered water from the refrigerator, which I highly recommend! It also looks nice! I like the night light feature too and the fact that this unit is super quiet. Read more
