Question about Holmes Products HAP422-UC Air Purifier
I have a red light on my air filter. I replaced the filter with a new one and the red light is still on .. can u help?
After spending hours searching for this supposed little hole easy to miss, I called customer service. I found out that it's easy to miss because it doesn't exist!
Here's the correct answer: Once you've replaced the filters, turn the unit back on. Then, with the machine running, press and hold down the on/off power button for about two seconds. The red light will flash and then turn off.

There is a little hole between the red light and green light that can be missed easy but its there. inset a small needle or straighten a small paper clip and inset it in the little hole till it clicks . Then hold for a few seconds and the red light will blink and go out if your filter is clean.

There is a little hole! just above it is a label that says "Filter Reset"
get a paperclip size pin and put it into the hole, you will hear a click
let the unit run a few minutes before it goes off. Make sure the filter is changed before attempting the above.
