=Dead Link=
 * The Link for " PUR™ Purifier of Water coagulation and flocculation water treatment system" is dead
 * I'll later need to find the specifically *most recent* version, but It is backed up on the Wayback machine
 * I don't know the procedures/chain of command for making this change, and also am just seeing this in passing, so i'll leave it at this for now
