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 used), you may need to check and replace the filters more or less frequently.
