• I’ve had it for a month. Supposedly it filters a larger square foot area - 500 sq. ft. This unit has an automatic setting that senses air quality and runs at the appropriate fan speed. On the 300 you have to manually select a fan speed. Nice convenience.

• Thank you for your inquiry. This unit has a more powerful motor, has a VOC sensor and setting to actively help reduce VOCs in the air, and is compatible with the optional Odor and VOC reducing pre-filters, along with an easier to control and read control panel. If you have any other questions please do not hesitate to contact our consumer relations team by emailing us at [email protected]. Thank you.
