With a growing number of small households that can only accommodate a small air purifier in each room, Union is a module-type air purifier that can suit different household needs. When separated, a single module performing at a lower power can be used in a child's room. Perhaps two modules would be sufficient for the master bedroom. And when set to maximum power with all three modules, it is perfect in the living room where everyone is gathered.
Union’s wireless recharger detects the air quality and displays blue when it is at its best, green when normal, and yellow when poor. The colour setting can be easily changed via the app. Consisting of three modules of a similar form, Union as a single air purifier amounts to the same effect as owning three air purifiers.
