I have cleaned the filters, and i still get the Clean Filter message. It is running fine, but the red letters Clean Filter are still there... any suggestions???

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

bad connection on plates or wires that run along the front of the plates in the cell. If you hear snapping or arcing then its the plates shorting out, look for bent plates and broken wires or loose sagging wires.

it may need a clean as there is a air flow sensor, if the flow is not right then it will have this on also a faulty sensor will read this aswell.

Make sure filter is positioned correctly and fully seated.

If it does not come on with a clean dry filter it may be a faulty high voltage component.

Wiping it off won't clean the filter. I submerse mine in hot soapy water ( oxiclean w/any favorite multipurpose liquid cleaner.Let it air dry completely before placing it back in unit.I have tried the dishwasher method and it didn't clean it.I also thoroughly wash all crevices of the unit.If red light doesn't go off, reclean the filter(s). It has all ways worked for me.

electronic circuit needs replacement

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 cleaned the filters as well earlier and the red filter light still blincked to clean the filters. Then I pushed the power button for about 10 seconds continously and then turned it on and the light turned off.

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.

After spending hours searching for this supposed little hole easy to miss, I called customer service. I found out that it's easy to miss because it doesn't exist!

Here's the correct answer: Once you've replaced the filters, turn the unit back on. Then, with the machine running, press and hold down the on/off power button for about two seconds. The red light will flash and then turn off.
