Why AirGenius is Smarter

  • 1.

    It does a great job of cleaning the air – even in a large room. The patented QuietClean® ifD® filter captures up to 99.9% of harmful particles as small as 0.3 microns from the air that passes through the filter.1,6

    Shhh….nearly silent setting helps clean the air while you sleep.

  • 3.

    It's REALLY Quiet – The honeycomb style filter doesn't resist airflow like paper filters do, allowing quieter operation.

  • 4.

    It's so Easy – Just Wash the Filter. Simply rinse the ifD filter in a sink only 4 times a year – no need to replace it.4

  • 5.

    It's like Turning on a Light – Uses about the same amount of energy as a light bulb – it's even Energy Star rated.

  • 6.

    Turns Off Automatically – Don't want to run it 24/7? No problem. Set it to turn off in 2 to 12 hours.

    It's Certified – and that makes a difference – The CADR (Clean Air Delivery Rate) performance is 3rd party tested & AHAM certified.

1 From the air that passes through the filter, 0.3 microns and larger. Overall particle reduction depends on many factors including the amount of air processed, the pollutant type and the pollutant introduction rate into the environment.

2 Germ claims are based on independent testing, report 100534705COL-001. Results are based on the testing of the reduction of the following bacteria, mold and viruses in the air after 2 hours of use operated at the high setting: Bacteria: Escherichia coli - 99.9% reduction, Viruses: MS2 - 99.9% reduction, Mold Spores: Penicillum citrinum - 72.3% reduction.

3 Based on 3rd party independent CADR testing for the smoke CADR value, when operated at the high max level. Air changes per hour calculations are based on the smoke CADR value x 60 minutes divided by the listed room volume (LxWxH) assuming an 8 foot ceiling. Air circulation depends on many factors, such as room size and configuration. There is no guarantee that all of the air in a room will pass through the filter.

4 Filter can be washed to clean, permanent claim based on washing 4 times per year for 5 years.

5 When operated with the odor reducing pre-filter. It is recommended that the pre-filter be replaced every 3 months to effectively reduce common household odors and gases in a room. This product does not reduce or absorb carbon monoxide gas. Make sure gas appliances are well ventilated.

6 The U.S. EPA defines harmful particles as those that are 2.5 microns and smaller.
