Abstract: An air filtering shelter 100 comprising a shelter frame 110 comprising a plurality of frame members 112 defining a sheltered area 102. Filter media 120 extends across the plurality of frame members 112, where the filter media 120 is disposed over the sheltered area 102. An airflow guide 130 extends across the plurality of frame members 112 between the sheltered area 102 and the filter media 120. The airflow guide 130 is impermeable and the filter media 120 and the airflow guide 130 define an airflow channel 125 between them. An airflow generator 140-1 is coupled to the shelter frame 110. The airflow generator 140-1 has an inlet 142 in the airflow channel 125 and an outlet 144 in the sheltered area 102.

Abstract: A storage container (100) comprising a housing (110) containing a storage chamber (112) isolated from an outside environment (10). The housing (110) defines a housing inlet (130) and a housing outlet (140). The storage container (100) is configured to clean air in the outside environment (10). The storage container (100) comprises a first filtration assembly (360) coupled to the housing (110) about the housing outlet (140). The first filtration assembly (360) has a first filtration inlet (364) configured to receive air from the storage chamber, a first filtration outlet (366) configured to release air into the outside environment (10), and first filter media (368) between the first filtration inlet (364) and the first filtration outlet (366).
