As minimalistic as it might be, the DrinKlean ZERO 1 mini air purifier packs a powerful, multifunctional punch! It can be used in one of three distinct ways. The first way can be used for immediate air purification even when you’re on the go. Using a convenient rubber handle, you can throw the durable unit in a bag or carry it while you’re camping. The second way works as passive purification on the charging hub. Leave it in your favorite room or in a workspace for consistent air cleaning you can set and forget! The last way is for more aggressive air cleaning. Attach the unit to the moveable stand for a direct blast of purified air in any direction. Use the smartphone app to adjust the strength in one of four intensities.
