The device operates with a 161 CFM clean air delivery rate, providing 4.8 air changes per hour. By utilizing a fully sealed housing, Levoit claims the 99.97% filtration efficiency at 0.3 microns applies to the air actually delivered back into the room rather than just the filter media in isolation. The unit is Energy Star 3.0 certified and includes the AirSight Plus 2.0 laser sensor, which monitors PM1.0, PM2.5, and PM10 particles to adjust fan speeds automatically.

A key design focus is the DuoShield filtration system, which allows the activated carbon filter to be replaced independently of the main HEPA filter. This modular approach aims to lower maintenance costs and offers users specific filter options for pet odors, smoke, or VOCs. The main filter is rated for up to two years of use. Measuring 9.4 by 9.4 inches, the unit operates between 20 and 50 dB, with a display that can be fully dimmed for nighttime use. The Eleva 300X is currently available on Amazon and the manufacturer's website.
