•  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.

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 HIGH ( ) setting to quickly 

circulate and filter the room air.  

FILTER CHECK INDICATOR

The filter indicator light eliminates guesswork by letting 

you know when it is time to clean the filters.

REMOTE CONTROL

The convenient remote control lets you select the filtering 

speed from anywhere in the room.

*Tested and listed by the Underwriters Laboratories, Inc.

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.

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. 

Potential for Radio/Television Interference. 

This device complies with Part 15 of the FCC Rules. 

Operation is subject to the following two conditions: 

(1) This device may not cause harmful interference, and 

(2) this device must accept any interference received, 

including interference that may cause undesired 

operation. This product has been tested and found to 

comply with the limits for a Class B digital device, 

pursuant to Part 15 of the FCC rules. These limits are 

designed to provide reasonable protection against 

harmful interference in a residential installation. 
The product generates, uses, and can radiate radio 

frequency energy and, if not installed and used in 

accordance with the instructions, may cause harmful 

interference to radio communications. However, there is no 

guarantee that the interference will not occur in a particular 

installation. If the product does cause harmful interference 

to radio or television reception, which can be determined by 

turning the product on or off, the user is encouraged to try 

to correct the interference by one or more of the following 

measures: 
  • Reorient or relocate the receiving antenna.

  •  Increase the separation between the product and 

the receiver.

  •  Connect the product into an outlet on a circuit 

different from that to which the receiver is 

connected.

  •  Consult the dealer or an experienced radio/TV 

technician for help. Changes or modifications not 

expressly approved by the party responsible for 

compliance could void the user’s authority to 

operate the equipment.

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. 

•  Remote control allows convenient operation from 

anywhere in the room.

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 completely 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. 

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 

Jarden Consumer Solutions Center. 

15. DO NOT place anything on top of unit.

16. NEVER use detergents, gasoline, glass purifier, 

furniture polish, paint thinner, or other household 

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. 

20. WARNING: To reduce the risk of fire or electric shock, 

DO NOT use this appliance with any solid-state speed 

control device.
