Note: If using a source of water that might contain extreme bacteriological or viral contamination, it is recommended that two drops of plain chlorinated bleach or iodine be added to each refill before filtering. This will kill minute pathogens such as viruses. The disinfectant will then be filtered from the water entirely removing its odor, color and taste.

     The 22 oz Sport Berkey Portable Water Purifier has a shelf life of 50 years. When the filter system will not be used for an extended period, flush the unit with a chlorinated solution of 1/4 tsp. per one half gallon of water. Allow to dry thoroughly with cap removed. Re-assemble and stow. Do not allow sport berkey to freeze, do not place in microwave oven and do not run hot water through the filter.

Note: All contaminants that this filter has the ability to remove or reduce may not necessarily be in the user's water supply.
