A filter assembly comprising:
- a self-supporting permanently electrostatically charged three-dimensional filter media made from a synthetic polymer fiber configured to filter non-gaseous items including dust and other airborne contaminants from a gas flow;
- and
- a plurality of attachment strips, each strip having a first portion attachable to the filter media and a second portion attachable to a housing surrounding an intake.
A filter assembly comprising
- a permanently electrostatically charged three-dimensional filter media made from a synthetic polymer fiber;
- a deformable frame positioned around at least a portion of the filter media;
- and
- attachment strips having first sides and second sides, the first sides being attached to the deformable frame and the second sides being removably attachable to a housing surrounding an inlet.
