Hapf600\600d hepa i would like to know how to reset the button after putting in new filters,i have tried putting in a paper clip and pushed down,nothing happen.

"After replacing the HEPA filters, RESET the Filter Life Monitor by inserting a small object (such as a pin or paper clip) into the hole below the red filter change light marked RESET and holding it down for 2-3 seconds." This came straight out of the Owner's Guide. Hope it helps!

According to the Owners Manual, here's what you need to do,

1.Turn the air cleaner OFF and unplug it from the power outlet.

2. Carefully lay the unit down on a flat surface with the Front Grille facing up.

3. Gently push in on Release Buttons on both sides of the unit, pull Front Grille out and away.

4. Remove and discard used HEPA filter.

5. Remove any plastic protective wrapping and from the new HEPA filter.

6. Set new HEPA filter into the air cleaner.

7. Install the Front Grille by engaging its tabs into the bottom slots on the unit. Then swing grille up and gently push in top to snap into place.

8.Turn the Air Cleaner upright and plug it into an outlet for
operation.

Hope this helped you. Please let me know. Thanks

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.

PREFILTER:

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

HEPA 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.
Depending upon your individual usage (environment and hours

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.

Hi Linda - there is a "reset" hole - you have to stick a pin or a paper clip in the hole when you change the HEPA filter - I just found this out myself! It does work. Mine didn't work right away, but it did end up resetting and went back to green after a few moments. I think this happened to me last time. The filters are really expensive, but you can get them at Walmart. If you need more information, email me at [email protected] and I'll tell you what model filter, etc.

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.

I have a Bionaire tower air filter model BAP1700 that I bought from Costco. The filter check LED came on recently after 5 months of use. After cleaning the Permatech filters, I tried every remedy on this website including following the instructions that say push power button for 2 secs. Nothing worked. Then I noticed a tiny hole on the control panel in front of clean filter LED; I pushed a paper clip pin into that hole, felt a click, held it down and 2 secs later, LED went out. Success!
