[CES 2011] The amount of human traffic at CES is tremendous each year, whether there is an economic downturn or not, and if you are rather paranoid about catching a bug from folks who drop by your booth, then you might want to see whether you need the Gaiam Air Sanitizer or not. Boasting advanced NCCO technology inside that sanitizes and removes harmful odors, airborne bacteria, dust and mold spores which kickstart allergies in humans, it also doubles up as an air quality monitor, showing the air quality level on top of the tower or through the LCD color display at the bottom. Airflow can be adjusted by setting the fan speed to your preference. The filter can last for up to three years before requiring a replacement, which is decent for the $179.99 you fork out.
