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.
To help prevent particles from attracting to surfaces throughout your home:
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 air purifier fan on.
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.
For optimum air filtration, operate your Holmes® air purifier continuously on the MEDIUM (2) setting. Its rugged motor has been designed to give many years of use. For quieter operation (such as in a bedroom), select the LOW (1) setting. When high levels of air pollution are present, select the HIGH (3) setting to quickly circulate and filter the room air.
The filter indicator light eliminates guesswork by letting you know when it is time to replace the filters.
Do not allow moisture to come in contact with the main housing of the air purifier.
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.
After approximately 4 months of operation, the Filter Check Indicator will light up to alert you to replace filters before further use.
To replace your filter:
Filters can be purchased at a retailer near you, online at www.holmesproducts.com, or by calling 1-800-546-5637.
