1. A mobile and foldable air-filtering isolation system for isolating an object in a room, the system comprising:
a base comprising at least one leg, the at least one leg comprising at least one wheel for rolling the base on the surface of the floor in the room;
a frame extending upwardly from the base, the frame comprising (i) at least one vertical riser having a longitudinal axis, and (ii) a top support having a longitudinal axis;
an air filtration unit mounted to the top support of the frame, wherein the air filtration unit comprises:
an air inlet formed in the housing;
an air outlet formed in the housing;
a passageway extending through the housing and connecting the air inlet to the air outlet;
a filter disposed in the passageway for purifying the air in the passageway;
a suction fan disposed within the passageway for drawing air into the air inlet through the filter and out of the air outlet;
a sensor for monitoring at least one of (i) the presence of chemicals in the room, (ii) the presence of biologics in the room, (iii) proper function of the air filtration unit, and (iv) the concentration of carbon dioxide in the room; and
an ultraviolet (UV) light source for sterilizing the filter;
wherein the air filtration unit is wirelessly connected to a monitoring and control system;
wherein the at least one vertical riser is configured to be selectively telescoped upwardly and downwardly so as to enable the height of the air filtration unit to be adjusted;
wherein the top support is hingedly mounted to the vertical riser such that the air filtration unit may be disposed in (i) a deployed position in which the longitudinal axis of the top support extends generally perpendicular to the longitudinal axis of the at least one vertical riser and parallel to the surface of the floor in the room, or (ii) a collapsed position in which the longitudinal axis of the top support extends generally parallel to the longitudinal axis of the at least one vertical riser;
wherein the base is hingedly mounted to the frame such that the base may be disposed in (i) a deployed position in which the at least one leg extends generally perpendicular to the longitudinal axis of the at least one vertical riser and parallel to the surface of the floor in the room, or (ii) a collapsed position in which the at least one leg extends generally parallel to the longitudinal axis of the at least one vertical riser;
at least one curtain configured to be mounted to the air filtration unit when the air filtration unit is in the deployed configuration, such that when the air filtration unit is in the deployed configuration and the at least one curtain is mounted to the air filtration unit, the air filtration unit and the at least one curtain together form an enclosure around the object to be isolated in the room; and
a storage container for storing the at least one curtain;
wherein the air filtration unit is configured to (i) withdraw air from at least one of the enclosure and the room, (ii) filter the withdrawn air, and (iii) return the filtered air to the room or the enclosure; and
further wherein the air filtration unit is configured to (i) withdraw air from at least one of the enclosure and the room, (ii) purify the withdrawn air by capturing at least one of viruses and microorganisms to the filter, (iii) activate the UV light source to irradiate the viruses and microorganisms captured on the filter, whereby to sterilize the filter, and (iv) return the purified air to the room or the enclosure.
