1. An air treatment system for removing contaminants from indoor air, the system comprising:

  • a source of indoor air providing an indoor airflow containing one or more contaminates;

    a source of purging air configured to provide a purging airflow to release contaminants adsorbed by an adsorbent;

    an air treatment module having one or more first air ports, one or more second air ports, and at least one insert including an adsorbent material, the at least one insert comprising a plurality of inserts;

    a support frame having one or more structural support members for supporting the plurality of inserts,wherein;

    the one or more first air ports and the one or more second air ports are formed by the support frame and the at least one insert, andthe plurality of inserts are planar and positioned within the support frame such that a surface of each insert of the plurality of inserts is at an angle of less than about 30 degrees relative to airflow paths between the one or more first air ports and the one or more second air ports;

    controls configured to cause the system to operate in at least three operational modes including;

    an active adsorption mode in which the adsorbent material of the at least one insert adsorbs one or more contaminants from the indoor airflow,a regeneration mode for releasing contaminants from the adsorbent material of the at least one insert when exposed to the purging airflow, anda disconnect mode where substantially no air flows through the air treatment module,one or more valves arranged and configured to direct, during one or another operational mode, at least one of the indoor airflow and the purging airflow to flow to and from the air treatment module via the one or more first air ports and the one or more second air ports; and

    wherein;

    during the active adsorption mode, one of either the one or more first air ports or the one or more second ports is configured to receive the indoor airflow and remaining one of the one or more first air ports or the one or more second air ports not receiving the indoor airflow is configured to expel the indoor airflow such that the indoor airflow flows over and/or through adsorbent material of the at least one insert, andduring the regeneration mode, one of the one or more first air ports or the one or more second air ports is configured to receive the purging airflow and remaining one of the one or more first air ports or the one or more second air ports is configured to expel the purging airflow such that the purging airflow flows over and/or through the adsorbent material of the at least one insert.
