I have a honeywell H H T-0800 model no Part no 30L b080CKAO I clind the filters and turnned it on and the green light and the red light stayed on the red light never was on when running Help please

Ignore the lights. Wash the outer foam filter every two months. As long as air is going through the inner filter does not need to be changed. Blow the inner filter out FROM THE INSIDE with your vacuum cleaner. (blow air the opposite direction of air flow to get the nasty stuff off.)

I have the same unit.
Have you cleaned out the removable filters?
also the red light at the bottom indicates the time to clean the filters.
to reset it, use a paper clip. The red light on the bottom right is the filter indicator light, what looks like it should be a light beside that filter light, is actually a reset button, just poke it with a paper clip for a few seconds to reset. The bottom red light goes out

check connection ware.

Thank you to MPODHOLA. After cleaning your Honeywell HHT-011, if the red light does not turn off locate the very small button under the red light. As suggested use a paperclip, hold the button for 5 seconds and this resets the system. Make sure the unit is on when you hold down the button. I tried it with the unit off and it did not work. Turned on the unit, held down the button for 5 seconds and the system reset. No more red light.

To the left of the little red light is the reset button. It's disguised as another light that isn't on. :) Press and hold it for about 10 seconds and the red light will turn off.

take somthing with a small tip, above the light there is a small hole stick it in lol. good luck!!!!!!!!!!!!

To RESET the Electronic Filter Check:
When the filter check light remains on,it is time to check/clean the HEPA-Type
filters and reset the filter check,if needed. With the unit powered on,insert the tip of a ball-point pen or
paperclip into the hole next to the LED filter check light and hold for approximately 5 seconds until the
light turns off (Fig 5). Depending upon your individual usage (environment and hours used),you may need
to check and clean the filters more or less frequently. If the HEPA-Type filters are cleaned before the filter
check light turns on,the filter check should be reset at the same time.
These cleaning intervals are intended as guidelines only. Performance of any filter media is dependent
upon the concentration of contaminates going through the system. High concentrations of contaminates
such as dust,pet dander and smoking will reduce the useful performance of the filter.
NOTE:The HEPA-Type filters are not washable.

When the filter monitor light remains on, it is time to check/clean the IFD™ filters and reset the filter
monitor, if needed. With the unit powered on, insert the tip of a ball-point pen or paperclip next to the LED
filter check light and hold for approximately 5 seconds until the light turns off (Fig. 3). Depending upon
your individual usage (environment and hours used), you may need to check and clean the filters more or
less frequently. If the IFD™ filters are cleaned before the filter monitor light turns on, the filter monitor
should be reset at the same time.
