Abstract
Embodiments of a filtration device, kit and method related to filtration in storm water systems are disclosed. A filtering device generally includes a mat adapted to filter water flowing through an inlet. The mat may have a top with a mesh cover, a main filtering portion and a bottom. The main filtering portion is formed of randomly-aligned fibers and a binding agent which impart a porosity that allows water to flow through generally unimpeded while sediment is filtered by the mat. A filtration kit is provided which could include the mat or other filtering device, a plurality of attachment members and a plurality of disks which allow for securing of the attachment members. Filtration device and kit are generally easy to install and clean, durable, less expensive than competing systems, and reusable.
