Abstract
Particles may be used to filter harmful biological material from an fluid stream such as air. The particles can be arranged into a bed to filter the harmful biological material from the fluid. The particles include a biocidal agent which is used to destroy the harmful biological material.
Claims49
An apparatus comprising:
- a bed of inorganic particles used to destroy harmful biological material from an air stream in a ventilation system for a building, each of the particles having interconnecting openings extending throughout the particle and opening onto an outer surface of the particle to form a reticulated labyrinth of struts;
- and
- a biocidal agent positioned in the reticulated labyrinth of struts, the biocidal agent being used to destroy the harmful biological material which enters the reticulated labyrinth of struts.
An apparatus comprising:
- a bed of inorganic particles used to destroy harmful biological material from an air stream, each of the particles including a plurality of pores;
- and
- a biocidal agent positioned in the pores of the particles, the biocidal agent being used to destroy the harmful biological material;
- wherein a mean size of the pores is about 0.1 microns to 100 microns.

An apparatus comprising:
- a bed of inorganic particles used to remove a filtrate substance from an air stream, each of the particles including a plurality of reticulated pores;
- and
- a reactive substance positioned in the pores of the particles, the reactive substance being used to chemically react with the filtrate substance and/or serve as a catalyst for reactions involving the filtrate substance;
- wherein a mean pore size of the pores is about 0.1 microns to 10 microns.
