SharpAir Purifier And Humidifier With Plasmacluster Ion Technology For Medium-Sized Rooms. Odor And True HEPA Filters For Dust, Smoke, Pollen, And Pet Dander May Last Up-To 5 years Each. KC850U

Q: Could you adjust the humidifier level on this unit? I have read some reviews complaining that it's too dry when using this.

Unfortunately the humidity level is not adjustable. I was concerned about that aspect when I purchased this unit but I have been pleased with it despite not being able to choose the humidity level. When the unit is left on "Auto" in the "Clean & Humidify" mode it keeps our medium sized bedroom around 50% (enough to moisturize your sinuses but not too much to cause condensation on windows). If you wanted more humidity you could have it on "medium" or "max" instead of "auto" though I am unsure just how high it would actually get.

Q: is it worth it to get the humidifier version?

I personally wouldn't bother with the humidity version. The largest model in the non humidity version covers more square feet for less money. You can always use a stand alone humidifier.

Q: Water tank refill indicator still on even when water is in the tank. Everything is put right back. Any ideas?

Look at the blue float switch. It needs to be “seated” below the tab that projects out from the side. If it’s above the tab, the light will never go off.
