ABSTRACT:
The instant invention is a disposable water cooler bottle filtration device. The filtration device is situated within the well of a conventional water cooler and employs an elongated tube with a centrally disposed piercing tip. The tip provides for the puncturing of the water bottle cap when the water bottle is placed thereon. Water flowing through the tube passes through a sub-micron filter capable of removing bacteria. Optionally activated carbon may be placed within the support structure providing removal of chlorine and known carcinogenic formed by chlorine combined by-products.
