Classic 300S Ultrasonic Smart Humidifier

Purchased the levoit 300S humidifier for a 300st/ft master bed and bath area. Works well and is has a relatively low noise level compared to the 600S with only a slight whistling noise. 300S is also easier to clean than the very difficult 600S. There are a few areas that are difficult to access and descale mainly the area around the secondary float.
There is a small water filter on the 300s in the top tank as well.
The 300S lacks a few features such as a storage clip on the unit for the included cleaning brush. I find that annoying on a high price unit. The humidifier also lacks a dedicated area for mineral absorption pad. I use the pads for the 600S since I buy them anyway. I've see no issue with performance. I've used the mineral pad tucked under the float (works best) and placed in the back of the unit (see pictures) you might be able cut them to fit where ever you want as well I've never tried it. The mineral absorption pads are worth the money. I have hard water so descaling the unit can be a chore, the mineral absorption pad helps with that as well as the annoying white dust. I normally use water from the fridge filter however I find my ZeroWater filter works best. Only need to do a minimal descaling job every 6 weeks now, with a quick weekly vinegar bath and brush.
The Max water line is at the upper handles I didn't see it on the clear plastic tank had to check the ownes manual. The app is just okay, it has adds that make it less than user friendly sometimes. The offending add sometimes blocks the main screen to access your device and controls, Forcing you to click the small X in the top corner of the add and then choose why you don't want to see this add. I'm sure They will most likely fix this in a future update. Typically I use the widget for quick on off and run schudules. I have other Levoit products so I am familiar with the app an use it daily.
The air purifier doesn't like the humidifier. When running side by side they purifier would detect the mist and run constantly. I now run them on opposite sides of 5ft dresser top and they do fine together. Overall it is a great unit and works well to humidifi my bedroom.
