Coway Airmega 200M True HEPA Air Purifier

The Coway Airmega 200M is a compact air purifier designed for bedrooms and similar rooms. It's listed for spaces up to 361 sq ft, or up to 874 sq ft at two air changes per hour. Air passes through four stages: a pre-filter, an odor filter, a True HEPA filter and a bipolar ionizer, which work together to reduce airborne contaminants.

An air quality sensor drives the Auto mode, which adjusts fan speed to the particles in the air, and an Eco mode saves energy. There are three fan speeds, a timer, a filter change indicator and an air quality indicator light you can turn off at night. The ionizer can also be switched off; when it runs, it produces ozone as a byproduct. The unit is CARB certified, draws 82 watts and runs at about 24 to 55 decibels depending on the setting.

At 12.3 lbs and 16.8 x 9.6 x 18.3 inches, it's easy to move between rooms. It suits pet owners and anyone who wants a simple, app-free purifier for a bedroom.
