Method and apparatus for sterilizing mail and textile articles

An apparatus for sterilizing various articles includes a chamber defining an airtight space and an entrance and exit. A vacuum pump is coupled to the chamber for withdrawing air therefrom which reduces the chamber air pressure. An ozone generator is coupled to the chamber for introducing ozone at atmospheric pressure therein following air withdrawal. This causes efficient diffusing of the ozone into the article for sterilizing it against anthrax. The ozone is then withdrawn into an ozone filter having a non-consumable catalyst for converting the ozone back into oxygen. The apparatus may be implemented using single or multiple chambers. A conveyor extending through water chambers surrounding respective sterilizing chambers may be utilized for conveying textile articles while more traditional conveyors may be utilized for traditional mail articles.
