Congratulations on your choice of the Kenmore HEPA Air Cleaner. We highly recommend that you operate the Air Cleaner 24 hours
a day, because indoor air can be quickly contaminated by activity or objects in a room and infiltration of outside air. Portable air cleaners
are much effective in rooms where all doors and windows  are closed 


The air cleaner has a two-stage filtering system. The first stage is a charcoal pre-filter. The second stage is the HEPA (High Efficiency Particulate Arrestor) filter. Room air is drawn into the Air Cleaner through the Air Intake Grille and passes through the filters. The filtered air is released from the top of the unit and is dispersed upwards into the room.

Two Filter Change Calendar Wheels are provided on the Air Cleaner control panel to serve as convenient reminders when to change the filters.


Your Air Cleaner was thoroughly inspected and tested at the factory prior to packaging. Visually inspect it upon removal from its box. Remove and discard any packaging material. Return the unit if it shows any signs of damage or mishandling.

Upon starting your Air Cleaner, set the Pre-filter Calendar Wheel ahead 3 months and the HEPA Filter Change Calendar Wheel ahead 12 months to remind you when the next filter replacement is needed.


Plug the Air Cleaner into a polarized 120-Volt AC wall outlet.

WARNING: To avoid the risk of fire or electric shock hazard, the air cleaner should only be plugged into polarized 120=Volt AC outlet.


CAUTION! NEVER operate the Air Cleaner without the HEPA filter properly installed. Permanent motor damage could result. 

Each time you start the Air Cleaner, it is a good idea to run it at Turbo speed for a few seconds. Then set it HI, MED or LO as desired.

TURBO initial Operation Fastest Cleaning

HI Maximum Operation Fast Cleaning

MED Daytime Operation Normal Cleaning

LO Nighttime Operation  Quieter Operation 


  • Pre-Filter: The pre-filter should be changed every three (3) months or sooner, depending upon the level of the room’s air contaminants and the frequency of use. 
  • HEPA Filter: The usable lifetime of the HEPA filter is 1 – 3 years, depending upon the level of the room’s air contaminants and the frequency of use. The air volume output will begin to decrease dramatically when the filter needs to be changed. You should have a spare filter available for later replacement.
