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.

I am 99.9% sure that you are simply looking at this year vs. last year models. There are absoutly no significant changes. I will verify on Mondayas I know the engineer at Honeywell that works on this particular product!

Honeywell does not have any serviceable parts. Get a new one.

Are you really unscrewing it? (to the left)? If not, then perhaps put a hammer handle on the handle at the outside rim and thump the hammer with the palm of your hand..

Normally Honeywell has NO replacement parts. Run it as is, then throw it away.

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.)

am sorry to disappoint you, once this condition is reached, it means the motor windings have overheated and your motor needs to be replaced, This is the only best thing to do to rectify this situation. This indicates that the insulation covering the wire used to make the winding of the motor has been cooked by the overheating and it is shorting out ,THIS WILL CAUSE THE MOTOR CATCH FIRE.
Please unplug the unit and have the motor replaced or buy a new unit for your safety.
