HIGH, MEDIUM AND LOW SPEED
SETTINGS
For optimum air filtration, operate your Holmes
®
air
purifier continuously on the MEDIUM ( ) setting. Its
rugged motor has been designed to give many years of
use. For quieter operation (such as in a bedroom), select
the LOW ( ) setting. When high levels of air pollution
are present, select the HI ( ) setting to quickly
circulate and filter the room air.
FILTER DATE WHEEL
This convenient feature helps you keep track of when to
change the filter.
BEFORE USE
1. Carefully unpack your Air Purifier. Select a firm level
place where there are no obstructions to the air inlet
or filtered air outlet.
2. If the filter is covered by a bag when shipped, remove
plastic bag before use and place filters into unit.
3. DO NOT POINT FILTERED AIR OUTLET TOWARDS WALL.
OPERATING INSTRUCTIONS
1. Plug into a 120V AC electrical outlet.
2. Select the desired operating speed; HI ( ),
MEDIUM ( ), LOW ( ), by
turning Speed Control Knob to the appropriate
setting.
3. To release negative ions into the filtered air, turn the
Ionizer knob to ON ( ) and the light will illuminate.
NOTE: The ionizer will not work unless the unit is
running. For optimum air filtration, it is recommended
to operate the air purifier continuously. Its rugged
motor has been designed to give many years of use.
CORD SAFETY
• The length of cord used on this appliance was selected to
reduce tangling or tripping hazards.
• If a longer cord is necessary, an approved extension cord
may be used. The electrical rating of the extension cord
must be equal to or greater than the electrical rating of
the air purifier (see rating label marked on product).
• Care must be taken to arrange the extension cord so that
it will not drape over the countertop or tabletop where it
can be pulled on by children or accidentally tripped
over.
GET TO KNOW YOUR AIR PURIFIER
• Your Holmes
®
air purifier features a HEPA-Type filter
that removes up to 99% of airborne dust and pollen
as small as 2 microns, and helps reduce smoke, mold
spores and pet dander from air passing through the
filter.
• Arm & Hammer
®
baking soda and carbon help
absorb and eliminate household odors.
• Optional ionizer naturally improves performance and
helps freshen the air.
IONIZER
This appliance has an optional ionizer feature which,
when turned on, releases negative ions into outgoing
filtered air to help the air purification process.
What Are Ions?
Ions are tiny particles that carry a positive or negative
charge. They exist naturally around us: in the air, water,
and ground. Both positive and negative ions are colorless,
odorless, and harmless.
How Does The Ionizer Work?
Negative ions help air purification by attaching themselves
to very small airborne particles in the room. These particles
take on a negative charge and may join with positively
charged particles such as dust, pollen, smoke, and pet
dander to form larger particles. These larger particles are
then more easily captured by the filter system.
Important Notes:
Your ionizer may produce an occasional popping or
cracking sound. This is normal and occurs when a small
buildup of ions is discharged.
After extended use, you may notice dust around the grills
or front panel. This is caused by negative ions exiting the
air outlet, evidence of the ionizer’s air cleaning
effectiveness. You can remove the dust with a soft brush
or clean, damp cloth.
Larger particles may be attracted to positively charged
surfaces throughout the home, like walls or floors.
• This may occur more frequently when the filter is
nearing the end of its useful product life and unable
to capture as many charged particles.
• Excessive amounts of pet dander, dust, or smoke may
decrease the life expectancy of the filter and
interfere with the ionization process.
To help prevent particles from attracting to surfaces
throughout your home:
• You may want to run the ionizer less often.
• Check the condition of the filter more frequently.
CAUTION: The ionizer in this appliance produces less
ozone than the UL* established limits of 50ppb. However,
in high concentrations, ozone can be harmful to birds and
small pets. To prevent ozone buildup, we suggest using
the ionizer in well ventilated areas with the fan on.
HEPA-TYPE FILTER
HEPA (High Efficiency Particulate Air) filters are
designed to remove up to 99% of airborne pollutants, at
2 microns or larger, from the air that passes through
them. These include tobacco smoke, household dust, pet
dander and pollen.
*Tested and listed by the Underwriters Laboratories, Inc.
IMPORTANT SAFEGUARDS
FEATURES - OPERATIONS
When using electrical appliances, basic safety precautions
should always be followed to reduce the risk of fire,
electric shock, and injury to persons. These precautions
include:
1. Read all instructions before using the appliance.
2. To avoid fire or shock hazard, plug the appliance
directly into a 120V AC electrical outlet.
3. If the filter is covered by a bag when shipped,
remove plastic bag before use.
4. Keep the cord out of heavy traffic areas. To avoid
fire hazard, NEVER put the cord under rugs, near
heat registers, radiators, stoves, or heaters.
5. To protect against electrical hazards, DO NOT
immerse the appliance in water or other liquids. Do
not use near water.
6. Close supervision is necessary when any appliance is
used by or near children, or disabled persons.
7. Always unplug the air purifier before moving or
cleaning the unit, opening the grill, changing the filters
and whenever the unit is not in use. To disconnect the
unit, be sure to pull the plug and not the cord.
8. NEVER drop or insert any objects into the openings of
the unit.
9. DO NOT operate any appliance with a damaged cord
or plug. If the motor fan fails to operate or the unit
has been dropped or damaged in any manner, return
appliance to manufacturer for examination and/or
repair.
10. Use appliance only for intended household use as
described in this manual. Any other use not
recommended by the manufacturer may cause fire,
electric shock, or injury to persons. The use of
attachments not recommended or sold by Jarden
Consumer Solutions may cause hazards.
11. DO NOT use outdoors.
12. NEVER place on a soft surface such as a bed or sofa
as this could cause the unit to tip over and block the
air inlet or outlet grills.
13. Keep unit away from heated surfaces and open flames.
14. DO NOT attempt to repair or adjust any electrical or
mechanical functions on this unit. Doing so will void
your warranty. The inside of the unit contains no user
serviceable parts. All servicing should be performed
by Jarden Consumer Solutions or an authorized

solvents to clean any part of the appliance.
17. Always turn the appliance off before unplugging it.
18. The ionizer in this appliance produces less ozone than
the UL established limits of 50ppb. However, in high
concentrations, ozone can be harmful to birds and
small pets. To prevent ozone buildup, we suggest using
the ionizer in well ventilated areas with the fan on.
19. This appliance should only be used in a room with
temperatures between 40° F and 110° F.

CLEANING/MAINTENANCE INSTRUCTIONS
1. Turn the air purifier off and unplug it before cleaning.
2. The outside of the air purifier can be cleaned with a
soft, clean dampened cloth.
3. The rear air inlet grill can be removed and washed in
warm soapy water (not dishwasher safe). Dry before
replacing in the unit.
4. The filtered air outlet can be cleaned of dust with a
small, soft brush.
5. If you wish to clean the inside of the air purifier, please

FILTER REPLACEMENT INSTRUCTIONS
IMPORTANT:
• DO NOT attempt to wash and re-use the HEPA-type
filter.
NOTE:
Every few weeks, check the condition of filters. Filter life
will vary, depending on air quality and usage. Under
normal conditions of continuous use, the HEPA-type filter
will operate efficiently for 3-6 months.
To replace your filter:
1. Turn off and unplug the air purifier.
2. Open the air inlet grill and examine the foam
prefilter. Remove any dust or lint, and wash in warm
soapy water. Rinse, drip dry, and place back into grill
inlet.
3. Remove HEPA-type filter from the unit by pulling it
gently towards you and discard it. DO NOT attempt to
clean the old HEPA-type filter.
4. Install the new HAPF30 HEPA-type filter into the
unit.This model utilizes a hang tab and filter clips to
insure that the filter is properly in place. Before
replacing the filter, make
sure that the hang tab is
securely in place. The
clip can only be attached
to the tabs on the filter
one way. The filter clip
should easily slide onto
the filter hang tab with
only a small amount of
pressure. DO NOT use
force while attaching the
clip to the filter. (Fig. 2)
5. Align the clip on the side
of HEPA-type filter with
rails on the inside of the
purifier unit. Gently slide
the filter onto the rail. (Fig. 3)
6. Replace air inlet grill.
