Features

Odor Sensor Function

This air purifier does not have a dedicated odor sensor function. While the activated carbon filter helps remove odors, there is no automatic adjustment based on odor levels.

Dust Sensor Function

This air purifier does not have a dedicated dust sensor function. The air quality sensor monitors overall air quality, but it doesn't specifically target dust particle levels.

PM2.5 Display Function

This air purifier does not have a PM2.5 display function. While it monitors air quality, it doesn't provide specific readings for fine particulate matter, limiting real-time feedback.

Filter Replacement Indicator Function

The filter replacement indicator notifies you when it’s time to change filters, ensuring the air purifier operates at optimal efficiency and maintains consistent air quality. This prevents reduced performance due to a clogged filter.

Child Lock Function

The child lock function disables the control panel to prevent unintended changes to the settings. This prevents children from accidentally turning off the air purifier or changing settings, providing peace of mind.

Sleep Mode Function

The sleep mode reduces the operating noise and dims the display lights for quiet operation during sleep. This allows for comfortable use in the bedroom without disturbing sleep, making it ideal for those sensitive to noise or light.
