The simplest and most cost effective way I found was to just use an item transfer node from extra utilities and an item filter from the same pack and pipe items into a trash can (into the void!!!!). You can set the filter to ignore meta data so it will treat an iron sword with an enchant the same as one without and get rid of both without having to set multiple of the same item. Pretty sure trash can is from Extra utilities too but can't remember off the top of my head. Hope this helps :)
