Question about Filter Queen Defender Air Purifier

2 Answers

Red light I turned on my Defender and it ran for about five minutes before the red light came on. I couldn't find the manual and this site was the first on google. I followed the instructions per the solutions on this website for resetting the unit. When I followed the directions I could not get the red light to flash to do a reset. What might be the problem? We have had this unit for about three years and only put about ten hours on it. I replaced the filter before I plugged it in at my new home and now I get the red light after five minutes.

The directions didn't work for me because the light would never continue to flash when I released. So I held the up/down buttons (didn't release them) and the red light flashed quick, then flashed slow and then went out. Not exactly what the directions say, but it worked.

Here is the link to the user manual; http://www.filterqueen.com/pdf/defender.pdf The red light indicates a filter needs replacing, see page 6 of the manual (page 9 of the pdf file) If filters have been replaced and the light still flashes, then the reset procedure (described on the same page) should work. If still flashing then there is a more serious, but probably fixable fault. Hope this helps - ask again if you need more info :)

SHARPER IMAGE IONIC BREEZE QUADRA RED LIGHT ON
I had one that had the "needs cleaning" light was on. After cleaning, the light stayed on. I checked around at the time and learned it couldn't be fixed, and it was out of warrantee. I believe that's why they stopped making them. Mine was just thrown away.

Mother gave me her filterqueen defender.. no manual. 360. There is a flashing red light even though its a new filter. Why?
The light is a reminder to change the filter, it does not sense if the filter has been changed or not.
When the red light is blinking, press and hold both up and down arrows until the red light blinks RAPIDLY, release both for a second or two, and press and hold both again until it stops blinking.

Blinking red light above the lowest setting on filter queen defender air purifier.
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.

Unfortunately Sharper Image has discontinued support on the product line.  There was a recall going on with the product but since the company is chapter 11 right now, I don't think it is being honored right now.  
What happened was Consumer Reports ran a test on ionizers, Sharper Image received a bad score and filed a lawsuit.  They lost the suit and had to pay all legal bills causing Sharper Image to reorganize.  
The EPA has reported that using ionizers in a house or business may be harmful to your health.  You can read an article about it on their website.  
The Consumer Products Safety Commission is going to release a final report on all ionizers by the end of the year.  Their decision may discontinue all sales of any ionizers in the United States.  This industry should have been regulated years ago just by the EPA data alone and for some reason it has been ignored.

If you have replaced your main filter you need to reset the red light. If you have not replaced the main filter you will need to contact your local filterqueen distributor. If you go to www.filterqueen.com they will direct you to your closest distributor and they can walk you through over the phone on how to reset your red light.

Orange light help
Did you find an answer to your orange light question? I have an AM4000 defender that I bought off Craigslist and thought I got a good deal on it. One minute after turning it on the red light came on. I tried to reset it but  the red light won't flash so you can't reset it. I don't know if it's a filter problem or a circuit board problem and I don't want to spend $100 bucks on filters to find out it's a different problem. If you buy filters on e-bay, they're cheaper but if you spend $100 from a distributor then you reactivate the warranty. I'm sorry I bought it.
