The Brita Corporation, producers of water filtration systems since 1968, offers a number of pitcher filtration products. The pitcher systems simplify filtering and storing water and make keeping cool drinkable water in the refrigerator easy. Using the Brita filter pitcher requires some planning and a place in the fridge but little else.
Prepare the filter for installation. A filter is commonly included with new pitchers. Submerge the filter in water for about 15 minutes before rinsing the filter in cold running water. Install the filter into the pitcher.
Fill the upper portion of the pitcher with water and allow it to move through the filter to the bottom portion of the filter. Discard this pitcher of water and repeat the filling process. Also discard the second pitcher full of water.
Fill the upper portion of the pitcher with water and place the pitcher in the refrigerator. If possible run the tap water on the sides of the upper portion of the pitcher rather than directly on the filter.
Change the filter about every 40 gallons. This is commonly about once a month under normal usage. Maximum efficiency is reached when fewer than 2 gallons of water is filtered per day. Repeat the filter soaking, rinsing and first use procedures from steps 1 and 2 when replacing the filter.
Brita filters remove copper, mercury, zinc, chlorine and cadmium with various efficiencies ranging from 66 to 96 per cent. Knowing the content of the tap water and the standard permissible levels for these chemicals helps the user determine if the filter will effectively remove enough of these elements to make the water safe and improve drinkability.
Do not fill the pitcher with hot or freezing water. Introduce water between the temperatures of 0.00 and 29.4 degrees C. Handle the filter only with clean hands to prevent contamination of the filter and ultimately the water in the pitcher.
