Cheongho Nais has launched ‘Just Air,’ an air purifier equipped with two filter systems on both sides of the unit for more powerful intake and faster air purification.

Just Air is a unit designed for spaces of up to 20 pyeong (66㎡), making it well suited for homes and small businesses. With its clean white color—highly favored by consumers—and simple body, it blends harmoniously into any indoor space.

The newly introduced Just Air features a double-filter system, with a three-stage filter system consisting of a pre-filter and a composite filter (dust-collection filter + deodorizing filter) installed at the intake on each side of the unit to efficiently purify polluted air. Its purification method is also designed with two intakes, quickly drawing in pollutants dispersed throughout the room and expelling fresh air widely through the discharge outlet at the top to rapidly purify the indoor air.

Just Air is equipped with dual sensors that indicate indoor air quality through three-stage color changes (Good, Bad, Very Bad—Blue, Orange, Red), allowing you to check the indoor dust condition and gas pollution level at a glance. In addition, it quantifies the fine dust concentration and notifies the user in real time, providing accurate information on indoor air quality.

Filter hygiene management has also been strengthened. The unit is equipped with a pre-filter cleaning notification indicator, and filter windows are applied on both the left and right sides to check the filter condition, enabling users to monitor pollution levels in real time and clean the filters when necessary. It also applies a BLCD motor to reduce noise, and an illumination sensor detects the surrounding brightness so that during dark hours the product’s lighting turns off and the airflow lowers to a weak level for the user’s convenience.

The rental fee is 21,900 won per month (based on a 72-month contract), offering reasonable pricing, and a service specialist visits every 12 months to provide inspection services such as filter replacement.
