The Bold air purifier is the perfect choice for anyone who wants to take care of the air quality in their home. A four-stage filtration system (particle filter, dust filter, HEPA filter, and UVC lighting) ensures maximum efficiency. Our HEPA 13 filter (PM2.5 - 0.3) removes 99.97% of all particles from the air, including dust, pollen, mold spores, and fine dust. The easy filter replacement allows for regular maintenance of the air purifier to ensure optimal performance. The filter has a lifespan of 2,000 hours (net operating time), and replacement filters are affordable. But that's not all: our activated carbon filter neutralizes unpleasant odors, and the UVC light kills bacteria and viruses. The high-quality, quietly operating Japanese motor allows for an air delivery rate (CADR value) of 510 m³/h. This enables the Bold air purifier to quickly and effectively clean large rooms. An integrated, switchable ionizer provides additional purification and freshness in the air. With smart home functionality, the air purifier can be conveniently controlled, monitored, and automated via an app (iOS and Android). The built-in child safety lock automatically shuts off the air purifier when the covers are removed. With three speed settings, the performance of the air purifier can be adjusted to meet individual needs. Alternatively, the purifier automatically adjusts its programs based on current pollutant levels. Operation is incredibly easy, whether you use the app, the remote control (requires 2 AAA batteries - not included), or the controls directly on the device. The extra quiet sleep mode ensures that you can spend the night undisturbed in a clean and healthy environment. Experience the difference in air quality and feel completely comfortable.
