In modern living environments, devices for keeping the air clean make a major contribution to the well-being of people. The Philips Series 3000(i) / 4000 combination devices are air purifiers and humidifiers in one. They simultaneously clean the air by removing pollution and allergens, while also adjusting indoor humidity to the desired level. Equipped with multidimensional wheels, the units can be easily moved around, offering comfortable operation. All settings can be accessed and made on its angled, highly user-friendly control panel on the front. In addition, users receive reassurance about the current setting via a numerical display. Suitable for any interior, this device impresses with its compact appearance and elegant design language. The design with an elevated rigid exhale grille on the top is visually underscored by an elegantly curved back, conveying the notions of performance with elegance. A metal mesh below the grille prevents objects from accidentally falling into the fan. In addition, the device’s robust water tank design features a release trigger that also secures the tank against accidental release. Merging an air purifier and humidifier into one unit in a symbiotic manner, the design of these combination appliances impresses with its subtle interpretation, with which it bestows the task of daily air purification with a new aesthetic.
