Question about Filter Queen Defender Air Purifier
2 questions since I have no manual:
1. Can I just replace the charcoal filter if the inside filter looks good?
I didn't have a blinking light even though I used the unit for 1 year.
2. Should I also change the inside filter anyway ?

To reset per the instruction manual: 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 this doesn't work repeat. Note on step 6: the FILTER REPLACEMENT INDICATOR must be flashing when the buttons are pressed the second time. Hope this works...:>)

I'm going to go out on a limb and guess you want the Defender model and not the Majestic model. I believe the latter is a vacuum. Here's a link to the Defender 360 manual. Best of luck.

Yes, but keep in mind the warranty requirements:

The Intelli-Check™ Filter Monitors will indicate replacement of the pre-filter and the
HEPA filter. Depending upon your individual usage (environment and hours used),
you may need to check and replace the filters more or less frequently.
To check Expected Filter Life Usage
When the unit is turned on, quickly press the appropriate filter monitor button. The
pre-filter light will flash up to 3 times and the HEPA filter light will flash up to 4 times,
depending upon how much expected filter life has been used.
1 flash = from new, up to 1/3 expected life used up
2 flashes = between 1/3 and 2/3 expected life used up
3 flashes = between 2/3 and all of expected life used up
Remains on = time to check/replace pre-filter
1 flash = from new, up to 1/4 expected life used up
2 flashes = between 1/4 and 1/2 expected life used up
3 flashes = between 1/2 and 3/4 expected life used up
4 flashes = between 3/4 and all of expected life used up
Remains on = time to check/replace HEPA filter
To RESET Filter Monitor
When the filter monitor light remains on, it is time to check/replace the filter and reset
the filter monitor, if needed. With the unit powered on, press and hold the appropriate
filter monitor button down for approximately 5 seconds until the light turns off.
