4 Different Types of Water Filters Explained

Types Of Water Filters

Everyone wants clean water when it comes to drinking water, hence the need for different types of water filters.

A home water filter can help many people get clean and good-tasting water free of smells, germs, pollutants, lead, and other potentially heavy metals and harmful substances.

These types of filters might appear the same, and there are significant variances between the various types and brands.

Water filters remove sediment, taste and odor, hardness, and germs from water, resulting in higher-quality water.

There are many different types of filtration purification systems (or water filters) on the market.

Each uses distinct water filtration methods to provide you and your family with cleaner, safer, and better water.

Nobody wants to invest money in a water filter only to discover that it answers an issue they don’t have.

However, with so many water filtration choices available, it can be challenging to choose the appropriate one for your home.

The one that not only improves the flavor of your water but also removes the most significant number of impurities.

Don’t be too concerned. It’s a lot easier than you think. This article follows the list of the most common types of water filters on the market to assist you in making a better decision about which water filters are best for your home.

1. Activated Carbon Block Filtration

Activation carbon block filtration is a type of water filter made of fine carbon powder held together by a binding agent and remains static.

In addition, this Activated Carbon Block reduces pollutants such as lead, volatile organic compounds (VOCs), and tiny cysts in water such as. It removes the taste of chlorine and odor, chemicals, and other pollutants from water very well.

Furthermore, When water passes through the pores of an activated carbon block, all pollutants larger than the pores are mechanically adsorbing and accumulating on the activated carbon surface.

Simultaneously, the positively-charged activated carbon attracts all negatively charged substances, such as chlorine, and eliminates the foul odor and taste.

Furthermore, this water filter is often inexpensive and provides excellent pollutant filtration. They remove chlorine taste and odor very effectively, have an excellent water flow rate, and long filter life.

They also preserve essential minerals and do not require energy.

The disadvantages of these filters are their inability to reach a high water flow rate and the need for a second sediment filter (for large sediments) to extend their lives and perform efficiently.

They are unable to eliminate viruses and excess minerals, and dissolved materials.

2. Ion exchange

As the name implies, Ion exchange filters are made up of a substance that will exchange one ion for another as water passes through it.

Ion exchange, for example, will substitute sodium ions for calcium or magnesium ions, which create water hardness.

The water will be “softened” as a result of this. If the water in your home leaves stains on washed dishes, you may have hard water.

Hard water tends to build up in pipes, reducing the life of some kitchen gadgets.

Ion exchange filters help with hard water and radioactive material, but they don’t remove organic material, particulates, bacteria, and other filtration alternatives.

These types of water filters have the advantage of being inexpensive and effective against dissolved inorganic pollutants.

Arsenic, fluoride, nitrates, sulfates, uranium, and other negatively charged contaminants can be removed by them.

They can also get rid of manganese, iron, chromium, magnesium, calcium, and other positively charged pollutants.

Furthermore, these types of water filters have the disadvantage of not removing sediments, organic pollutants, or microbes. The Ion-Exchange (IX) resin is susceptible to bacterial development, and its operating costs are high.

3.Sediment Filtration

Sediment filtration is one of the different types of water filter that is the most frequent and simplest water filtration method used in homes and various industries across the globe.

It effectively removes sediments such as rust, sand, dust, silt, heavy metals, and other big water particles.

A sediment filter is frequently used as a prefilter in various household water filtration systems, such as the Activated Carbon filter or a Reverse Osmosis filtration system, to prevent the rest of the filters from becoming blocked by big particles.

The Benefits of Sediment Filtration include Cost-effectiveness. In water, it’s effective against sediments and big particles, and replacing is also a simple procedure.

Furthermore, Sediment Filtration’s Negative Effects includes Chemicals and pollutants smaller than 1 micron that cannot be removed. Before providing safe and pleasant drinking water, they must be used with other filters.

4. Reverse Osmosis Filtration

Reverse osmosis is a filtering method that uses a semipermeable membrane (also known as a RO membrane) to remove inorganic pollutants from water and produce the purest drinking water possible. It can remove most contaminants (up to 99 percent, including minerals) from water.

Because of the slow pace of water filtration, most reverse osmosis filtration systems include a pressurized tank to hold the filtered water.

Furthermore, because the RO membrane is susceptible to chlorine, a Reverse Osmosis filtration system will always have at least one activated carbon filter as a prefilter to eliminate chlorine.

The Benefits of these types of water filters include Providing the most effective filtration against the vast majority of pollutants detected in the water.

They also dissolved solids, iron, calcium, lead, cysts, mercury, bacteria, and other impurities removed or significantly reduced.

The type of water filter also produces the clearest and cleanest water.

Chlorine, certain pesticides and organic pollutants, solvents, and volatile organic compounds are not removed (VOCs) is one of the Reverse Osmosis Filtration’s Disadvantages.

Filtration of water is slow is also another disadvantage. Reducing the pH level of water by removing essential minerals.

And they cannot be used to treat chlorinated tap water on its own. And to have a high cost of purchase are parts of the disadvantages of this type of water filter.

5. Distillation

Distillation is one of the different types of water filters that have been widely used for an extended time.

However, it is not as well used as the activated carbon and reverse osmosis filters. It, however, does an excellent job of cleaning water.

The water distiller evaporated the water by heating it to boiling temperature with electrical energy. The steam is then caught and condensed into liquid form, resulting in pure distilled water.

The Benefits of Reverse Osmosis Filtration include: Providing the most effective filtration against the vast majority of pollutants detected in the water.

Dissolved solids, iron, calcium, lead, cysts, mercury, bacteria, and other impurities can be removed or significantly reduced. They also produce the clearest and cleanest drinking water. 

Furthermore, this type of water filter exhibit a slow water filtration process. They also remove essential minerals, therefore, reducing the water Ph level.

The high operating cost is also a significant disadvantage of this type of water filter.
