This filter is advertised as compatible with Body Glove (BG6000FF). Unfortunately, it ruined the BG head unit. When I attempted to replace the American filter with a BG filter, I could not screw it in. Nada. It reformed the plastic internal mechanism. I called BG who confirmed that when an American Filter is screwed into a BG head unit - it causes permanent damage to the head unit. I had to order a new BG head which cost me $53.11. I notified American Filter who denied responsibility.
