This air purifier’s display has separate indicator lights that show the status of its Wi-Fi connection and filter health. The ‘Air’ and ‘Odor’ dials are color-coded to give you a quick estimate of current air quality based on particulate matter counts and noxious gas levels, respectively. In descending order:

• Green
• Yellow
• Gold
• Orange
• Pink
• Red

There are also separate buttons to engage the ‘Auto’ mode, which allows the device to set fan speed depending on current air quality, ‘Ultimate Clean’ mode, which is similar to the ‘Auto’ function but defaults to the highest fan speed required, and ‘Eco’ mode, which causes the device to run the fan only when needed to save energy. The ‘Turbo’ mode sets the device to its highest fan speed for 1/2 an hour, one hour, or two hours. There’s also a ‘Timer’ button that allows you to manually set the length of its operating in any mode: you can have it run for 1/2, two, four, eight, or 12 hours before turning off.

You can use the NuWave Connect App to remotely operate the air purifier, monitor current air quality, or check filter health.
