SOURCE: red light on air filter

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.

SOURCE: hepa filter

The red light indicates a plugged filter. Replace the filters plug the machine in and get a paper clip. Streighten out the clip and put it through the tiny hole in the top. You'll feel it push a switch that will give a click you can feel. Keep holding the clip wire down for several seconds. When the red flashes remove the clip wire. The light will stay off if the filter is clean.

Actually, your purifier is working as it should. The black soot is due to the negatives ions which attach themselves to the smoke/dust/dirt particles in the room and make them drop to floor. If you don't smoke it won't be much of a problem. Some minor residue will be found in and around the unit but this comes about because the negative ions make dust and other particulates fall to the floor. A quick wipe or vacuum easily eliminates this problem. Besides, I would rather have them on the floor than floating around in the air, wouldn't you?

the unit probably needs to be reset. cause what's happening is that it's not recognizing that the filters are clean. there should be a tiny pin hole at the top of the unit. when the unit is on you need to put a small needle in there and hold for about 5 seconds and the unit should reset. if that doesn't work please please let me know and i will see what else we can do.

The trouble began in 2003 when Consumer Reports magazine published a report claiming the expensive air cleaners don't clean air. The magazine later claimed its tests showed that Sharper Image's Ionic Breeze Quadra Silent Air Purifier and four other units also release potentially unhealthy levels of ozone.

Red filter light still on-


ok i'm not finding that model anywhere in my system. but one way you can try is look in your manual under troubleshooting. if you have gone through all of the troubleshooting. the best thing that i can suggest is call the manufacturer. if your still under warranty they should be able to replace the unit foryou.

Kaz Honeywell Tower Air filter rest light


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.
