An air treatment apparatus comprising:

• a plurality of air treatment units, at least one of the air treatment units comprising an air inlet, an air outlet, and an air treatment device located between the air inlet and the air outlet;
• and
• connecting components,
• wherein the air treatment device within the air treatment unit comprises at least:
• a component for air purification and filtering, heating, dehumidifying, humidifying, air-cooling, and/or components of a blow-through fan, a draw through fan, or a pump,
• wherein the air treatment device in the air treatment units are of different types,
• wherein the air treatment units are linkable and connectable by the connecting components, the connecting components further comprise a transmitter and a receiver, the connecting components comprising a Wi-Fi module, a Infra-red transmitter, or a Bluetooth connection module,
• wherein connection of the air treatment units is non-substantially performed,
• wherein the air treatment units are adapted to operate in a first mode in which the air treatment units operate in coordination with one another together as a built system and a second mode in which the air treatment units operate alone as separate individual units, and
• wherein the air treatment units are configured to operate in the first mode and the second mode according to at least one level obtained by at least one environmental sensor, the first mode and the second mode providing different air treatment efficiency and performance.
