4. Showerhead filter

Showerhead filter

It is a quite similar device to the faucet filter you can install directly on the showerhead. That way, you can use filtered water while taking a shower. It is an excellent option for you if you live in the region with the water containing high levels of chlorine, chloramines, and fluoride.

6. Water filter pitcher

Water filter pitcher

Since the water filter pitcher is cheap, reliable, and portable, it is probably the most common type of filter for water purification you can find on the market. There are two parts to the carbon filter. When you pour water through the first filter filled with activated carbon, you will get the clean water in the low part of the tank.

You can use it to filter tap water or take the system with you when going camping and use it outdoors. Unfortunately, its capacity is limited.


  • That portable filter is easy to use
  • It removes most minerals and chemicals from water

Best Water Filtration Methods

You should choose the most appropriate water filtration method. The best solution for your home will depend on the type of impurities you need to remove.

Reverse osmosis

Reverse osmosis system moves water through a semi-permeable membrane to stop harmful molecules larger than water. Keep in mind that it needs far more water than it produces.

Activated carbon

During the process of purification, carbon bonds water particles through a chemical reaction. It improves the taste and odor of water by removing chlorine. This method is useless in removing arsenic, nitrates, and fluoride.

Granulated carbon

It is a filter that uses small grains of carbon for filtering the water. However, it is not highly efficient due to its small surface area.

Carbon block

These block-shaped filters have a large surface and, consequently, excellent sediment-holding capacity. Water speed will highly influence its effectiveness.

Water softening

It replaces calcium and magnesium in drinking water with sodium during ion exchange. Avoid this method if you have high blood pressure since the water you get after filtration is full of sodium.

Activated alumina

You should use it if you have water contaminated with arsenic, fluoride, and selenium. It is a standard part of cheaper domestic filters but has a limited lifespan.


Even though using water distiller is one of the oldest methods of water purification, many people still choose this reliable way to clean their water. In general, it is a process of vaporizing water by heating to high temperatures and removing microorganisms and minerals, having a high boiling point. However, you can’t get rid of chlorine this way.


It is a method, which promotes ion exchange and removes salts from water. Unfortunately, it is not an option for eliminating viruses and bacteria.


Keep in mind that this device often has on-board water filters, but it is not primarily designed to be a water filter. Without the significant capacity to remove the broad range of impurities or long-term health benefits, this expensive method is not suitable for home use.


Most customers combine this method with others because ozone kills microorganisms effectively, but can’t remove chemicals.


It is a reliable, cheap solution lasting for years. Its pores will stop impurities larger than their size. If you purchase the model treated with silver, you will get a filter killing bacteria and preventing mold, as well.


You should pick out this method if you need to remove sediments and cysts from water. Unfortunately, if your water contains chemical contaminants, it is not a useful option for you.


It is an excellent, contemporary eco-friendly option for removing viruses and bacteria from drinking water by using ultraviolet light of different frequencies. Unfortunately, this method is expensive. Plus, you may have difficulties to purchase necessary equipment since it is not a commonly used system for cleaning the water.


It is a great solution for softening drinking water if you live in a region with a hard one. It uses light and heat to charge your water negatively and make it soft.


Water filters are a necessity in the contemporary world. Depending on the model you choose, they remove or reduce contamination by a chemical or a biological process, as well as a physical barrier.

Thanks to these convenient and reliable devices, you will get clean water without pesticides, viruses, bacteria, and various industrial run-offs. Get your water tested, determine your needs, and pick out the best filter for your home.
