This is an electronic air purifier. It uses what is known as an ionizer to filter out the dirty air. The electronic air purifiers have two sections for getting rid of dirty air. One section is for ionizing and the other section is for collecting the dirt. In the ionizing section, dirty air particles pass between ionizing wires and plates connected to a high voltage power supply.

• Releases high-density negative ions (negative ions>/=3 million/cm3) to purify the surrounding air-- Negative Ions eliminate airborne contaminates such as dust, pollen, mold, smoke, pet dander, and bacteria, germs, allergens.
• Negative ions control with Low/High settings for small/large rooms.
• High electrostatic plate traps the dust, pollen, smoke etc.as small as 1 micron circulated in the air.
• Does not use replacement filters.
• Easy maintenance:just wipe the dirt down from the collector rod (never has to be replaced) with a cleaning cloth.
• Covers up to 500 square feet.
• Wisper quiet operation.
• Runs 7-24 cleaning.
• Ultra-low energy use: runs only on 8 watts.
