How to stop Hunter HEPAtech Filter Model air purifier 30,212 flashing lights? I replaced the two pre-fiter and the main filter and tried to reset the time by pressing the reset and for 3 seconds each time without success. I also tried unplugging and resetting again and again no luck. The unit is not so old and I replace the filters regularly. Any help is greatly appreciated.
Get the filter, and then back on if the light goes out, you may have trouble with the fan or the filter has a problem.
