Before you buy any type of water for your home, whether a jug from the store, a filter or even a water cooler, it’s wise to know more about the various water filtration methods that may have happened before you take a sip. Some filtration methods are better at removing particles and contaminants than others. Here’s a quick overview of each type of water filtration method.
1. Activated Carbon Water Filtration
Carbon removes contaminants by chemically bonding to the water that is poured into the system. Some are only effective at removing chlorine, which only improves taste and odor, while others remove more harmful contaminants, such as mercury and lead. It is important to note that carbon filters do not have the ability to remove inorganic pollutants such as nitrates, fluoride, and arsenic. Carbon filters are usually sold in block or granulated form to consumers.
2. Distillation Water Filtration
Distillation is one of the oldest water purification methods. It vaporizes water by heating it to exceptionally high temperatures. The vapor is then condensed back into drinkable, liquid water. Distillation removes minerals, microorganisms, and chemicals that have a high boiling point. These filters cannot remove chlorine and many other volatile organic chemicals.
3. Deionization Water Filtration
Deionization filters promote ion exchange in your water in order to remove salts and other electrically charged ions. If a contaminant lacks an electrical charge, it will be removed by these filters. Living organisms, such as viruses and bacteria will not be removed by these filters.
4. Ion Exchange Water Filtration
Ion exchange technology uses a resin to replace harmful ions with ones that are less harmful. Ion exchange is often used to soften water since it has the ability to replace calcium and magnesium with sodium. In order for these filters to work for extended periods of time, the resin must be regularly “recharged” with harmless replacement ions.
5. Reverse Osmosis Water Filtration
Reverse osmosis works by moving water through a semi-permeable membrane in order to stop larger, more harmful molecules from entering. Since this process can only block molecules that are larger than water, contaminants with larger molecules, such as chlorine, cannot be removed. Reverse osmosis systems are able to remove more contaminants than carbon, making them a popular choice for many consumers. These filters consume far more water than they produce, so they are best suited for domestic use.
6. Mechanical Water Filtration

Despite the fact that they cannot remove chemical contaminants, mechanical filters are an excellent option for consumers hoping to rid their water of sediments and cysts. Mechanical filters contain small holes that remove these contaminants, and they are sometimes used alongside other filtration technologies. If your water supply contains an undesirable amount of dirt and other particles, you may want to consider purchasing a mechanical filter.
7. Ozone Water Filtration
Ozone is often employed alongside other technologies, and it is renowned for its ability to effectively kill large numbers of microorganisms. Ozone filters do not remove chemicals, but if you are worried about getting sick from your water, this may be your best option.
8. Carbon Block Water Filtration
Carbon block filters are block-shaped filters that are composed of crushed carbon particles. These filters tend to be more effective than other types of carbon-based filters since they have a larger surface area. The rate at which water flows through these filters has a direct impact on their level of effectiveness. Fibredyne carbon block filters have a greater sediment-holding capacity than other types of block filters.
9. Granulated Carbon Water Filtration
As the name suggests, these filters use small grains of carbon to filter your water. Due to their rather small surface area, granulated carbon filters tend to be slightly less effective than their block-shaped counterparts. Much like a carbon block filter, their level of effectiveness is strongly influenced by water speed.
10. Water Softeners Water Filtration
Water softeners employ ion exchange technology in order to reduce the amount of magnesium and calcium in the water. This is especially useful if your plumbing fixtures are prone to accumulating mineral buildup. Since these harmful elements are replaced with sodium, water treated with this process tends to contain high levels of sodium. If you cannot consume large amounts of salt, it is best to avoid softened water. It is also unwise to water plants with softened water since it contains such high levels of sodium.
