A coated, reticulated foam air filter for filtering air suitable for respiration is described. The air filter comprises a reticulated foam structure and a nontoxic tackified coating applied to a functional surface of the foam structure.

Coated, reticulated foam air filter suitable for respiration

A system having a kickstand bracket is described. The kickstand bracket has a leg stop groove and a mount position, the leg stop groove having a boundary and a recess between ends of the boundary. The recess is configured for accepting a leg stop when a kickstand is rotated from a first position to a second position. An alignment locator is configured to attach to the kickstand bracket over the leg stop. A spring is attached at one end on the kickstand and at the other end on the mount position of the kickstand bracket, the spring configured for urging the kickstand towards the second position.

Kickstand system and upgrade method

A wet filter which will not foul washing facilities and plumbing systems, and which will not introduce harmful substances into the environment. The filtering element, which mayk be a resilient, open cell foam material or a woven fabric, is coated with a mixture of oil and a tackifying agent. The oil is preferably a vegetable oil, and the tackifying agent is preferably a dimer acid. The oil and acid are mixed in a volatile carrier, such as ninety-nine percent pure isopropyl alcohol. Preferred proportions are fifty percent dimer acid and ten percent vegetable oil, by volume. The filter is saturated in the mixture. The alcohol is permitted to evaporate, thereby leaving the foam filter thinly yet fully coated with oil and acid. The filter may be washed in water and detergent for renewal. Preferably, a biodegradable detergent mixed with an alkaline substance such as soda ash is employed in washing the filter. Although the tackified oil is water resistant, the disclosed detergent enables suitable dispersal when water washing. After washing, the filter may be treated with new oil and acid mixture, allowed to dry, and reused.
