In January 2026, the global technology community turned its attention to Las Vegas as the world’s premier consumer technology exhibition, Consumer Electronics Show 2026, opened its doors. Among the many emerging technology themes, indoor environmental health became one of the most closely watched sectors.
From disruptive water-based purification technologies to modular heated tobacco devices, from AI-driven air management systems to pet health monitoring ecosystems, a wave of innovative products and integrated solutions unveiled at the exhibition is painting a clear picture of the future of respiratory health management.
At CES 2026, the “CUE” air purifier introduced by Korean technology company Watervation attracted significant attention. Unlike traditional filtration-based purifiers, this device adopts a groundbreaking water-based purification approach.
Technology Principle
CUE utilizes Watervation’s proprietary WVG (Water Volume Grid) technology, which sprays ultra-fine water particles to maximize surface contact with airborne pollutants. The system effectively captures particulate matter and harmful gases by washing them with water. This approach addresses two persistent challenges of traditional filter systems: the accumulation of pollutants within filters that can lead to secondary contamination, and the environmental burden associated with filter disposal.
Commercial Value
The filter-free design significantly reduces maintenance requirements for users while improving hygiene and sustainability compared with conventional air purifiers. Watervation plans to launch CUE globally through the crowdfunding platform Kickstarter in the first half of 2026, followed by expansion across global B2C, B2B, and B2G distribution channels. CEO Jung Yoon-young noted, “Just as rainfall cleanses the air in nature, we are now applying technology to realize the concept of purifying indoor air with water.”
At the same exhibition, Chinese brand Dreame Technology showcased several pioneering technologies. Its FP10 pet hair air purifier received certification from Frost & Sullivan as the world’s first air purifier equipped with a self-cleaning rolling filter mechanism. The system uses Dreame’s proprietary dynamic roller self-cleaning technology to maintain long-term filtration efficiency.
Another highlight was Dreame’s intelligent dual-airflow system, inspired by aviation engine fluid dynamics. The system automatically identifies pollution sources and switches between a long-range jet airflow (up to 10 meters) and a wide-area diffusion mode. A single unit can cover up to 157 square meters. The device also incorporates AI sensing with built-in millimeter-wave radar capable of detecting movement within a 5-meter range and 120° field of view. When a user approaches, the purifier automatically activates and dynamically directs purified airflow toward the user—achieving a true “airflow follows the user” experience.
2. Smoking Harm Reduction: Breakthroughs in Modularity and Intelligence
In the heated-not-burn (HNB) segment, the globally launched REJO CUBE by REJO drew considerable industry attention during its debut in Japan.
FlexiCUBE™ Modular Design
REJO CUBE features a magnetic modular architecture that connects a heating chamber with a detachable battery module. The device is available in three colors—Mint Green, Ink Black, and Honey Berry—and supports up to nine visual combinations depending on component configuration.
