How do you reset the filter on the HHT-145 - Honeywell HHT-145 Air Purifier

According to what I found, if the filter is not reinstalled just right, it won't trigger the filter being back inplace switch.Also, try unplugging the unit for 30 minutes and then plug it back in. That may reset the switch. If tall else fails, call Honeywell Customer Service at 877- 841-2840.

Hope this helps to solve the problem, JR.

IT COULD BE THE ELEMENT the attacked link should get you to the manual

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.

1. Plug unit into outlet. 2. Press power ON/OFF switch to the ON position. 3. Allow unit to start running at low speed. 4. PRESS and HOLD both the UP and DOWN arrow buttons until the FILTER REPLACEMENT INDICATOR starts to blink. 5. Release both the UP and DOWN arrow buttons. 6. While the FILTER REPLACEMENT INDICATOR is still flashing, again PRESS and HOLD both the UP and DOWN arrow buttons untile the FILTER REPLACEMENT INDICATOR turns off.

If the steps above have been performed properly, the Filter Replacement Indicator will turn offand not flash again for 11 months. If the Filter Replacement Indicator remains on, repeat the steps again.
*Note that in step 6 above, the Filter Replacement Indicator MUST still be flashing when the buttons are pressed the second time.The Filter Replacement Indicator will continue to flash for approximately 3 seconds after the buttons are released as required in step 5 above.

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

I have had the same problem. The way I fix mine (it only runs for a couple days staight) is to switch the two filters (or maybe you just need to remove completely?) making sure they are in tight. Replace the cover and it should work!
