How Does a Brita Water Filter Work?
Water is perhaps the most vital substance to life on earth. More than half of our body mass is composed of water, requiring a daily replenishment for optimum function. Most experts recommend consumption of a minimum of eight glasses of water per day. This lofty figure may leave us concerned with the content and overall healthfulness of the water we are drinking. The makers of numerous water purification devices claim that we shouldn't be so naive about our H2O intake; that in fact, public drinking water contains high levels of chlorine and other harmful minerals such as copper and mercury. These claims can leave a human feeling not at all thirsty. The Brita Water Company has been producing solutions to water filtration for almost 4 decades. These aids come in the form of pitcher and faucet filtration devices that promise to remove harmful chemicals from drinking water and improve the overall taste and aroma.
What Is In The Water?
Water that is drawn from a tap, or household faucet, comes from either a well or a public water-treatment facility. Both reservoirs of water may offer several unwanted minerals that can make it taste and smell unpleasant, and which cause it to be labelled as "hard" water. Most households that use well water use a water softening treatment to help soften it. Public water, also treated in a plant, can come with certain minerals; as well as, added chlorine to keep it from breeding bacteria. Treatment plants can also add minerals like fluoride to help improve the strength of the drinker's teeth. The removal of objectionable extras in our water is desired in order to provide the best taste for our drinking water and the recipes which use that water, and to keep our bodies, pipes and appliances free from harmful substances such as lead or even arsenic.
How It Is All Removed
All Brita devices use a two-part filtration system. The first is a sheet made of carbon that is activated by heat in order to make it extremely absorbent. The carbon is covered with large pores which give it a greater surface area. These pores suck in all impurities as they are poured through. Leftover ions are caught by an ion-exchange resin which neutralises the ations and cations. The whole process takes place in just a few minutes and what you are left with is a purified glass of water which the company guarantees has a reduced level of Chlorine, lead, copper, cadmium and mercury. Keep in mind, the water also contains a reduced level of fluoride and the chlorine, that was added, was there to prevent bacteria growth; therefore, leaving a glass of filtered water around for more than 48 hours is definitely not recommended. Because, the filter holds no means of killing any bacteria, changing the filter on a regular basis (which the company suggests is around 3 months) is a must; otherwise, you are just pouring your water through a sheet of carbon ridden with bacteria and other impurities.
