Solid performer 


I've owned the HWM450, HWM450NC and now the HWM500. I'm not sure which I like best.
This one has a larger water tank.
Quiet so far.
Shuts off when empty.
Warm mist produces larger volumes of moisture (no white powder).
Does not allow me to set a humidity and forget it -- then again the hygrometer on the 450s were way off. I'm not a fan of the switch back to mineral pads vs. the updated heating element on the 450NC.
Not a fan of the UV light as I see it as a gimmick likely to prevent my machine from working once the bulb burns out.
Dream combination
My ideal would be the layout of this machine, but with the tank split in two (for my grandmother who cannot lift the tank) with a hygrometer that's accurate to within 5% and the heating element of the HWM450NC. I'd make the UV light optional so those that want it can use it but not have it prevent the system from running. Also, I'd include a green light to indicate that everything is okay -- i.e. when the orange and red are off the green should be on.

so far, so good! 

We've had this humidifier for a couple of weeks now and it is working fine. It is not too noisy and we feel better knowing there is a UV light that gives extra protection from the possibility of spewing germs into the air. I gave it only 4 stars because it does require extra cleaning attention -- the interior surfaces are not non-stick and you have to be very careful about mineral deposits on any exposed metal part. It is time consuming to let it soak in vinegar every time.

Great item! 

This is the second humidifier like this that I have purchased.  The first one lasted nearly ten years.  It is a great product and really helps out the winter dryness.  It doesn't spew white dust over everything and it keeps my sinuses moisturized.  Exactly what I wanted.
