Ability and FunctionEdit
- "A Gleet BioFilter destroys all life-forms whose DNA is not entered into the computer controls. Andalite technology, of course. The Yeerks must have stolen the specifications."
"Ax, are you telling me that filter thing will wipe out any life-form except the one they program it for?"
"Yes, Prince Jake. I'm sorry to say, yes. Everything but the particular human-Controller."
- ―Ax and Jake
It scans all life forms that go through the are and if an unauthorized life form is detected, it emits a loud alarm and blast wide-range rays which can blind humans and kill any life form whose DNA pattern isn't entered into the computer controls. It can be programmed for individuals such as humans or for a species.
When someone passes through a Bio-Filter without their DNA pattern being listed in the computer's database, it sounds an alarm, giving the would-be intruder only seconds before the device kills them via laser beams. Visser Three ordered that all Bio Filters be programmed in order to kill intruders immediately, but the Animorphs survived (with injuries) in their fly morphs.
