Germ Guardian FLT4825 HEPA GENUINE Air Purifier Replacement Filter B for GermGuardian AC4300BPTCA, AC4900CA, AC4825, AC4825DLX, AC4850PT, CDAP4500BCA, CDAP4500WCA and More, 1-Pack , Gray Condition: Open-box new. Store return. Unused. Filter itself is undamaged and factory sealed in plastic. However the original box looks to have been dropped in water. I don't know why someone would return a perfectly good filter just because the box they were going to throw out anyway got wet, but that seems to be what happened. Please see pictures.
