Unless your tap water has an odd smell, such as the odor of rotten eggs, or looks obviously discolored, you have no way of knowing whether or not your drinking water is safe for consumption. Here are four reasons every home should have residential water filters.
Your Water Will Taste Better
Even when water is tested and found to contain no contaminates, that doesn't mean it will necessarily be palatable, or taste good. Many municipalities add chlorine to their water, which is not considered a contaminant but rather a guard against dangerous microorganisms. While the taste is subtle, it is nonetheless there, and it can make coffee, tea, and other beverages that use tap water taste funny.
Your Water Will Be Better For You
Some studies show there is a positive association between esophagus, bladder, breast, and colorectal cancers and drinking chlorinated water in women. Fluoride is another chemical frequently added to the municipal water supply. The American Dental Association insists that fluoridating the drinking water has proven safe for seventy years and has reduced cavities by 25 percent, in both adults and children.
However, as the Harvard T.H. Chan School of Public Health points out, the U.S. Public Health Service lowered its recommended levels of fluoride in drinking water in 2015. With claims the scientific studies of the past 70 years were flawed, and the realization that countries that don't fluoridate their water have seen the same decline in tooth decay, the benefits do not outweigh the risks. Too much fluoride can actually damage teeth and bones.
More importantly, fluoridated water may cause brain and nerve cell damage, potentially resulting in cognitive and other issues. Every citizen should have the right to decide for themselves whether or not they want these substances in their water. A reverse-osmosis water filter with a carbon block will remove chlorine and fluoride from your water supply.
Your Water Will Be Cheaper
If you are accustomed to buying bottled water because you don't like the taste or trust the purity of your tap water, a water filter will save you money. It will also dramatically reduce your use of plastics, which aren't good for the planet. Instead, you can use reusable containers, such as aluminum or stainless-steel water bottles or glass pitchers.
Your Water Will Retain Its Minerals
Water filtration systems remove harmful bacteria, such as cryptosporidium and giardia, but they won't remove the good mineral deposits that keep the pH balanced. This is important for palatability.
