Method of operating an air cleaning cluster

A computer implemented method of operating an air cleaning cluster (20, 20′) comprising a plurality of air cleaning devices (10, 10.1-10.n) arranged in a room comprising a volume of air (100), the method comprising:

• receiving, by one or more control device(s) (30, 30′, 30″ 30.1-30.n), data indicative of air quality within the volume of air (100);
• receiving, by the control device(s) (30, 30′, 30″ 30.1-30.n), data indicative of operational state(s) of the plurality of air cleaning devices (10, 10.1-10.n);
• and
• the control device(s) (30, 30′, 30″ 30.1-30.n) controlling one or more of the plurality of air cleaning devices (10, 10.1-10.n) of the air cleaning cluster (20, 20′) such as to influence the indoor air quality within the volume of air (100), using the data indicative of the indoor air quality and the data indicative of an operational state of the plurality of air cleaning devices (10, 10.1-10.n), wherein the step of controlling the air cleaning cluster (20, 20′) comprises controlling the plurality of air cleaning devices (10, 10.1-10.n) of the air cleaning cluster (20, 20′) such that the data indicative of the air quality corresponds to an indoor air quality target value;
• and
• wherein the step of controlling the air cleaning cluster (20, 20′) comprises controlling the plurality of air cleaning devices (10, 10.1-10.n) to remove at least a portion of contaminants from the volume of air (100) by recirculating within the volume of air (100) comprised by the room in which the plurality of air cleaning devices (10, 10.1-10.n) are arranged in, the recirculation comprising
• drawing in air through an air inlet (12) of each air cleaning device (10, 10.1-10.n),
• forcing, by air propelling means (15), at least a portion of the drawn-in air through one or more air cleaning filters (14) of each air cleaning device (10, 10.1-10.n) to physically capture a portion of contaminants from the portion of the drawn0in air, and
• returning at least a portion of the filtered air through an air outlet (16) of each air cleaning device (10, 10.1-10.n).
