Abstract
A device and method include ionizing particles to be captured, creating electric fields to polarize mats of filter material, and trapping the ionized particles in the polarized mats.
Claims13
A method comprising:
- ionizing particles to be captured;
- creating electric fields to polarize mats of filter material formed of conducting fibers and mats formed of non-conducting filter material disposed between adjacent mats of conducting fibers;
- and
- trapping the ionized particles in the polarized mats.

A method comprising:
- ionizing particles to be captured;
- creating electric fields to polarize mats of filter material;
- trapping the ionized particles in the polarized mats;
- and
- measuring a capacitance across the mats of filter material.
2 more elements
A filter comprising:
- multiple mats of conducting filter material formed of conducting fibers;
- multiple mats of non-conducting filter material, each non-conducting filter material mat disposed between adjacent mats of conducting material;
- and
- electrodes coupled to the mats of conducting filter material to create an electric field between successive adjacent mats of conducting material to enhance filtering of ionized particles in fluid flowing through the filter.
