How to Choose Drinking Water Filters


Carbon Water Filter          Drinking water quality is one of the most important and often overlooked health concerns facing families in the US today. Many families drink water straight from their tap and use it for cooking as well. Little do they know there are a myriad of impurities in the drinking water some much worse than others that can cause harmful effects to the human body ranging from gastrointestinal distress, to bacterial infections, to body inflammation and even nerve tingling. Luckily there are many drinking water filters on the market that can either be attached directly to your faucet for water purification or even used in pitcher filters to filter water poured into the container. There are many different types of filters and water filtration technology so be sure to review different options when buying one. First familiarize yourself with the problems that unfiltered water can cause and then find an appropriate solution.

Step 1

Chlorine in WaterDrinking water in the US via your faucet is not the best way to get your water. It is convenient and cheap but the water should be filtered before being used to drink or for boiling and cooking. Many municipal cities across the country treat their water with chlorine or chloramines to destroy bacteria in the water before it reaches your home so that you will not get any bacterial infections. This bacteria comes from the rivers and lakes where the water is being taken from and needs to be destroyed before it comes out of your faucet. Most municipalities do a great job at this with chlorine and chloramine. However what is not necessarily common knowledge is that chlorine and chloramines have deleterious effects on the human body as well. While they do kill off bacteria they also cause a host of other problems in the human body when injested. Chlorine is a toxin as its gaseous form, chlorine gas, was used in World War I to cause harm to the lungs and body when inhaled. The chlorine used in water treatment is a liquid version of chlorine that is pumped into the water supply. It is usually in small concentrations but varies between each city and town. You can check the level of chlorine in your tap water supply by going to your city’s water website and finding the information on a water report or by purchasing chlorine test strips.

Step 2

Chlorine is bad because it can cause a variety of issues in the body. Once ingested chlorine reacts with water in the body’s tissues to form hydrochloric acid. This can then cause inflammation and damage to the body. Chlorine toxicity in the body can cause many different symptoms ranging from nerve tingling sensations to inflamed lungs, chest, esophagus etc. This is why you should remove all the chlorine from drinking water with an appropriate drinking water filter.

Step 3

Review the different types of drinking water filters out on the market. There are many different types but basically you have your standard faucet mount, under sink, and pitcher container water filters that come in forms of carbon granules, carbon blocks, and KDF filter materials. The faucet mount drinking water filters will attach directly to your kitchen faucet usually with a snap on fitting such as the PUR or Brita faucet water filters. These filters usually have a carbon block that filters out chlorine, chloramines and a host of other microbes and by products of chlorine’s interaction with organic molecules. Carbon filters do a great job at reducing chlorine and chloramine levels as well as levels of some cysts like Giardia.

Step 4

Water Pitcher FilterThe carbon fine filters work in the same way as the carbon blocks but are made of tiny flakes of carbon material in a small filter. These filters are installed in pitcher filters where the water is led by gravity to drain into the container passing through the carbon filter at the same time to remove the impurities.

Step 5

The other type of filter is a KDF filter. KDF filters remove chlorine through a reaction between copper and zinc fines in a filter media. KDF filters have a better rate of chlorine removal in very hot water than carbon filters. That’s why they are used for shower filters. But they are not as popular as carbon filters for drinking water purification.
