SO HAPPY WITH THIS PURCHASE!
Beautiful and works well. VERY easy to fill and you can add tabs to keep the water fresh. I love the remote, you don’t even have to get off the couch to start, stop or increase misting or level of humidity. You can even add aroma oils if you like. This replaced a seven year old humidifier I had previously, and I am very happy with the new replacement.

It’s got an incredible mist!!!
BEST humidifier ever. I love all the designs features. There are not a lot of parts that will mold. Assembly was simple and it has a remote control! It is perfect mist and doesn’t leave water anywhere and no droplets from the mist.The wand is fabulous that it’s extended to reach your face without a table while sleeping. LOVE IT!

The merchant fixed the problem!
Right out of the box the unit would not go more that 42 or 43. I followed the merchants recommendations and sent an email to the address that was provided. Absolutely, no response in 4 days now. Non-existent customer service I guess!!!Update: The merchant responded and sent me a brand new unit that is working great!!! Nice piece of machinery!!!

Use distilled water
The unit is well built and easily keeps the moisture at a good level. The directions said to use distilled water or purified water. I priced distilled water and found it to be an expensive option so I’ve been using home filtered water. White dust created from the unit gets pulled into the furnace filter and actually plugged it up to the point of the furnace shutting down. I changed the filter and reset the furnace. If I decide to keep the humidifier I will be checking the furnace filter and replacing more often.

As described
Very easy to put together , lots of controls on remote. down fall tube it’s to short since it has wheels I’ve ordered a plant stand that wheel should fit through to lift humidifier higher so mist tube reach where I need it to go

It’s Huge, But Don’t Look Too Closely at the Plastic
This Monisen humidifier is the largest one I have ever gotten. Most of my previous units are 6 liters, and this one holds nearly triple that amount at 17 liters. Since it gets really dry here in the winter, that huge capacity is very welcome and means a lot less refilling, which is great when you have young kids.Besides the capacity, the smart functionality is useful. It connects to wifi and can be added into the Tuya smart home app. The app displays current humidity data and allows some control. The touch buttons on the unit are responsive, and it also features auto shut off when the room’s humidity hits 40 percent. This unit makes maintaining proper room moisture surprisingly effortless.The only drawback for me is the quality of the build itself. It is very noticeably cheap plastic. It may look decent from a distance, but up close, the materials used are a bit embarrassing. Despite the cheap construction feel, the massive size and functionality still make it a worthwhile choice for tackling serious winter dryness.
