One of the basic human needs is to have clean water. In our homes, water comes from taps or faucets. So, how sure are you that this water is clean? Usually, water that comes to your home travels for miles via an old network of pipes before reaching your tap.
So… How Do Water Filter Pitchers Work? Blocking the contaminants flowing in the water filters usually, use a cartridge filter or an activated carbon filter. When you pour water into the pitcher, the filter it will remove unpleasant smells, also will reduce the amounts of Copper, Zinc, Sediment, Mercury and Chlorine.
Although that water is clean in appearance as it is treated in the local water treatment facility, passing through pipes is likely to pollute it. These pipes are the abodes of all sorts of contaminants, including harmful chemicals, different microorganisms, and heavy metals.
To remove these impurities, you need a water filter pitcher. Regarded as an affordable solution, it is a self-contained unit designed to purify tap water.
A water filter pitcher typically has a water container to encompass different volumes. It is usually composed of a lid, a container of variable volume, and one or two filters. This post is dedicated to share with you about how a water filter pitcher works.
Working of a Water Filter Pitcher
Pitcher filters feature distinct types of media in them, as per its make and brand. The most used medium is activated carbon that can easily decrease contaminants and impurities. Another common medium is a cartridge filter that works by implementing the ion exchange technology. Let’s check them out.
Pouring water into a pitcher will first make the water enter into a filter where the impurities are removed. Then, the water gradually goes into the actual container.
Once you use the pitcher to pour water into a glass, a diversion system allows it to leave the unit without going through the filters coming in the way.
Activated Carbon Filters
A carbon filter is typically made using coconut shells, wood, petroleum pitch, and coal. The carbon is activated physically through either carbonization, oxidation, or chemical activation. Once activated, it is used to make a filter.
An activated carbon filter then functions on the basis of adsorption, a natural phenomenon in which the atoms of dissolved solids, liquid, or gas stick to a surface. The activated carbon features a highly porous surface with many corners and crevices providing much space for the ions to get trapped by entering inside.
Just one gram of activated carbon is capable of providing an adsorption surface of around 32,000 square feet. The credit goes to its high porosity. When water goes into the filter, maximum atoms of contaminants will stick to the porous surface. This is how water becomes healthier.
How Often Should You Change Your Water Filter
After some time, the porous surface gets packed with various particles. From this point, the filter does not remain efficient in attracting new atoms. Thus, you should change the filter at regular intervals as per the instructions of the manufacturer.
The large carbon surface is capable of removing metals such as lead, copper, chlorine, cadmium, zinc, and mercury; organic compounds affecting the odor and taste of water; and chemicals such as pesticides and chlorine.
It can even remove trihalomethane compounds that are by-products of chlorine treatment, volatile organic chemicals, and giardia and cryptosporidium that are protozoan parasites.
Nevertheless, these filters do not remove all contaminants. They cannot discard all nitrates, viruses or bacteria, and dissolved minerals. These impurities do not bind to carbon.
However, dissolved minerals are not mandatorily risky. Further, most tap water is treated to discard harmful microorganisms. Thus, it is not a big deal if such water passes through a carbon filter pitcher.
Some filter pitchers come with an ion exchange resin that is designed to remove hardness from water. In other words, calcium and magnesium ions are removed. Thus, ion-exchange filters are ideal for softening water.
They are made to split the atoms of a pollutant to make ions, which are electrically charged atoms having too few or too many electrons. Then, these ions are trapped and less troublesome ions are released. In simple words, they exchange bad ions for good ones.
Ion exchange filters feature many zeolite beads holding sodium ions. When you pour hard water full of magnesium and calcium compounds into an ion-exchange filter, the contained compounds split to generate their ions.
The beads attract these ions more than sodium due to which they trap magnesium and calcium ions. Finally, the beads release their ions of sodium for replacing them. The resulting water has no magnesium and calcium ions due to which it tastes softer as well as more pleasant.
As sodium is just another form of contaminant, the water resulting due to ion-exchange filtration is not considered pure. Sodium can be an issue for those on low-sodium diets. Further, it is essential to recharge the filters regularly by instilling more sodium ions, usually by inducing some special salt.
A cartridge filter is an advanced mechanism that a few makers use to remove contaminants from water. While many cartridge filters employ activated carbon, others employ technologies for giving you a better water taste.
A few cartridges are such that they pass water through seven stages of filtering prior to releasing it in a water container. They use ion exchange resins, activated carbon, mineral balls, and tourmaline at different stages to filter the water.
Mineral balls tend to instill minerals in water. Generally, when water enters a water filter, a few good minerals inside the filter are also streamed out. The resulting water, thus, has fewer nutrients.
However, mineral balls resolve this issue by introducing new minerals once the water is filtered. Thus, the nutritional value of water is raised and the water becomes healthier for anyone to drink.
If a filter uses the tourmaline mineral, it works by transferring a small electric current that reverberates in the Far Infrared Spectrum (FIR) of water. As a result, water molecules resonate through these FIR frequencies, which are also there in your body. This means that metabolism power will get a boost after you drink this tourmaline-treated water.
Water filter pitchers have different mechanisms to purify hard water or adulterated water. They range from activated carbon to tourmaline mineral filters.
