Abstract: Some embodiments of the present disclosure relate to improving or overcoming at least one problem in existing air filters by including at least one folding structure in or on the air filter. The folding structure is capable of being bent to enable the air filter to be wrapped around or secured to a, for example, washing net. The folding structure can also hold the air filter securely to the, for example, washing net.

Abstract: An air quality indicator for indicating high fine particle levels in an environment of interest. The indicator includes a frame maintaining first and second air filter media. The first air filter medium differs from the second air filter medium at least in terms of a change in visual appearance (e.g., color) when subjected to air flow containing fine particles.
