Check and replace the pre-filter. Check and replace the HEPA filter. Check and replace both filters. Note There is a sticker on your air purifier to remind you what each color indicates. Understanding the ionizer The ionizer releases negative ions through the filtered air that will attach to positively-charged particles, such as dust and pollen, and it will cause the particles to settle out of the air. It automatically turns on when you turn the speed control knob to the speed you want. Caution The ionizer in your air purifier produces less ozone than the UL established limits of 50ppb (parts per billion). However, in high concentrations, ozone can be harmful to birds and small pets. To prevent ozone buildup, use the ionizer in well-ventilated areas with the fan on. Notes • The ionizer may produce an occasional popping or cracking sound. This is normal and occurs when a small buildup of ions is discharged. • You may notice more particles on the surfaces in your home or on the filtered air outlet of your air purifier. This is normal and means the particles are being removed from the air. • Excessive amounts of pet dander, dust, or smoke may interfere with the ionization process. • The ionizer cannot be turned off. 8 www.insigniaproducts.com
