Help with Air Purifier Holmes, the red check light?

I have a Holmes Air Purifier Tower. its HAP422 the series. in the upper left corner is a check with a circle around it. and under that light is red. Any idea why? Read the guide of all the owners and cash, says nothing about the red check. who just turned today. Often not even use. and filters are clean and new. What could be?

I had the same thing happens on mine. I'm trying to find an answer, but I can say that is a light that is defective is supposed to be off when changing filters. I simply be ignored. By the way, do not use the ionizer. It is supposed to be bad for you.
