An air treatment system comprising: an air purification assembly comprising one or more air purification modules and configured to, in an upstream to downstream order, take in air, produce purified air by conveying the air to traverse the one or more air purification modules, and expel the purified air; and an aerosol source configured to release a conditioning liquid in aerosol form into the purified air. Optionally, the conditioning liquid comprises a predetermined concentration of nonpathogenic micro-organisms. Optionally, one or more air purification modules comprises, in an upstream to downstream order, a HEPA or ULPA filter, a UVC irradiation unit, and an activated carbon filter.

There is provided a system for circulating air. The system for circulating air has a concrete element that has an open cell porous matrix concrete. The concrete element has an inner surface opposite an outer surface. The inner surface faces an enclosed dwelling space of a building. The system for circulating air has an air circulation conduit in fluid flow communication with the outer surface of the concrete element, and a fan configured to circulate air along the air circulation conduit and through the open cell porous matrix, across a thickness of the concrete element, into the enclosed dwelling space.
