About Your Ionic Comfort® Plus
Thank you for purchasing the Ionic Comfort® Plus Electrostatic Air 
Purifier. We are dedicated to making your life cleaner and healthier 
with creative solutions that combine superior quality with the very
latest technology.
The Ionic Comfort® Plus provides fresher, cleaner air for you to breath 
and saves you money at the same time by eliminating the need for 
expensive replacement filters. With a revolutionary quiet fan system, 
advanced ionic cleaning and patented high efficiency filter design, 
your Ionic Comfort® Plus helps remove common pollutants such as 
dust, pollen and tobacco smoke from your air, along with smaller, 
more dangerous atomic sized particles that traditional HEPA air 
purifiers can leave behind. And, because it’s whisper quiet, the Ionic 
Comfort® Plus can be placed in any room in the house or office – even 
your bedroom.
Your Ionic Comfort® Plus has been thoroughly tested to meet our own
exacting quality control standards. Please take a few moments to
