Question about Holmes Products HAP422-UC Air Purifier
The red light indicates a plugged filter. Replace the filters plug the machine in and get a paper clip. Streighten out the clip and put it through the tiny hole in the top. You'll feel it push a switch that will give a click you can feel. Keep holding the clip wire down for several seconds. When the red flashes remove the clip wire. The light will stay off if the filter is clean.

The Intelli-Check™ Filter Monitors will indicate replacement of the pre-filter and the
HEPA filter. Depending upon your individual usage (environment and hours used),
you may need to check and replace the filters more or less frequently.
To check Expected Filter Life Usage
When the unit is turned on, quickly press the appropriate filter monitor button. The
pre-filter light will flash up to 3 times and the HEPA filter light will flash up to 4 times,
depending upon how much expected filter life has been used.
1 flash = from new, up to 1/3 expected life used up
2 flashes = between 1/3 and 2/3 expected life used up
3 flashes = between 2/3 and all of expected life used up
Remains on = time to check/replace pre-filter
1 flash = from new, up to 1/4 expected life used up
2 flashes = between 1/4 and 1/2 expected life used up
3 flashes = between 1/2 and 3/4 expected life used up
4 flashes = between 3/4 and all of expected life used up
Remains on = time to check/replace HEPA filter
To RESET Filter Monitor
When the filter monitor light remains on, it is time to check/replace the filter and reset
the filter monitor, if needed. With the unit powered on, press and hold the appropriate
filter monitor button down for approximately 5 seconds until the light turns off.
