How to choose the best water filter

Contaminants in your water source

Every water source has contaminants. If your water source is tap water or public-supplied water, there are contaminants present, such as:

  • Chlorine
  • Fluoride

If your water source is another rather than tap water, there are impurities that you will find such as:

  • Bacteria
  • Virus
  • Heavy metals

Bottled water has become the primary source of drinking water in the whole world, but this water also has contaminants such as chemicals that are present in plastic bottles.

Most bottled water is tap water which has impurities. Besides having impurities, empty bottles are thrown away daily causing pollution. Also, it is very expensive compared to water filters.

Choose a water filter that will help remove contaminants in your water source.

Where to install a water filter

There are two places where you can install a water filter: point of use (POU) and point of entry (POE). POU water filters clean water at a point of consumption this is filters installed under the sink, on the faucet, or either through a pitcher or at the countertop unit. POU is what every home requires most to make sure you have safe drinking water.

POE treats all the water that enters your home. It is installed in a particular place just after water enters your home.

Method of filtration

The water filtration method is not the same as water purification. Learn more about water purification methods.
Water filtration uses different methods such as:

  • Sediment filtration

Sediment filtration helps remove contaminants such as sediment and suspended particles.

  • Carbon filtration

Carbon filtration filters are made of granular activated carbon (GAC) or block carbons. GAC has an electropositive charge which attracts negative ions of contaminants and sticks to the surface of carbon material giving you clean water.

It uses a process called adsorption.

Benefits of carbon filtration

  • Removes sediment in the water
  • Removes tastes and bad odors in the water
  • Reduces the amount of hydrogen sulfide
  • Cost-effective but requires changing filters more often

Disadvantages of carbon filtration

  • Not suitable for removing heavy metals such as fluoride, arsenic, and many others
  • Not useful for removing inorganic impurities
  • Reduces the water flow rate
  • Kinetic degradation flux (KDF)

It is also called copper-zinc systems. It uses chemical processes and granules of zinc and copper to filter water. When water passes through copper and zinc granules, some of the impurities are drawn toward zinc, and others are attracted to copper. Then there is the chemical process that is added which releases ozone and compounds that kill contaminants like bacteria and organisms.

This method is effective when combined with other methods that utilize carbon and particulate
It uses Zinc- Copper formulation and a chemical process called oxidation formulation.

Advantages of KDF

  • KDF eliminates heavy metals such as lead, mercury, and fluoride
  • Effective for removing chlorine and hydrogen sulfide
  • Remove certain bacteria, fungi, and viruses

Disadvantages of KDF

  • For it to produce safe water it is combined with other methods to filter water.

Types of water filters

There are different types of water filters available in the market. These include.

  • Whole house water filters

A whole house water filter is installed at the mainline water entry. It helps filter water for the entire house. Read our review on the best whole-house water filter.

  • Undersink water filters

The under-sink water filter is installed under the sink and filters water that comes from the tap. It requires enough space under the sink.

The best under-sink water filters include:

  • Countertop water filter

A countertop water filter is a unit that is placed on the tops of kitchen sinks, water filter stands, tabletops, and refrigerators.

Another form of countertop water filter is attached to the faucet and has a diverter valve that allows you to switch between filtered water and tap water.

The best countertop water filter include

  • Faucet water filters

The faucet water filter is fixed or mounted to the faucet, but they don’t take up counter space. It has a valve that allows choosing between filtered water and tap water.

The best faucet water filter system includes

  • Water filter pitchers

They are like jugs with filters that help treat a maximum of 10 glasses of tap water.

The best water filter pitchers include:

  • Portable water filters

They are used for camping, traveling, backpacking, and anyone who enjoys the outdoors. Portable filters are water filter bottles and purification tablets.

  • Hydro packs or emergency filters

This is an emergency water filter. They are used in times when there are floods, earthquakes, and severe and periodic water shortages.

  • Shower and bath filter

They are installed in the showers. One of the reasons for considering a shower and bath filter in your home is the health risk associated with daily exposure to the chlorine by-product in tap water while bathing and showering.

  • Refrigerators filter
  • Alkaline


The amount of water your family consumes every day determines the type of water filter you require.

There are some filters that give you a limit or unlimited amount of filtered water.

Modern features

Nowadays water filter comes with advanced technology such as a filter change indicator which alerts you it’s time to replace a filter.

Filtration rate

Some water filter slows down the water flow rate which makes too much time to get enough water you need for your family.

Other water filters speed up the water flow rate which increases water pressure, which is too strong and can damage the pipes.

The required water pressure rate is between 55-65 Psi.


To make sure you have a good water filter, make sure the filter is not only certified by the manufacturer but by an independent body such as NSF International and the water quality association. You can check the independent certification body available in your country.

Replacing, annual and maintenance costs

Most water filters are cheap, but the cost of replacing filters and maintenance cost is more expensive than the filters themselves.

Also, consider some water filtration method that wastes a lot of water if your water supply is from the Municipal you will end up incurring high water rates annually.

Ease of use

Most water filters do not require professionals to install them. When buying look for the water filter that has an installation guide and when you need to change the filter that is easy to change.

Permanent or nonpermanent

There is some filter that is installed permanently which is required you to drill holes to mount them and requires a professional to fix them. Permanent filters are not suitable for a renter or dorm resident because it requires permanent modification.

Others are non-permanent you don’t need the drilling of holes or modification to install them.

Customer service and support

Water Filters have a warranty range of six months to one year. If you have any questions regarding the issue, you need a manufacturer that has friendly customer service either in the form of email or call support.

Longevity and Warranty:

Consider the lifespan of the system and the warranty provided by the manufacturer. A longer lifespan and a comprehensive warranty can give you peace of mind and protect your investment.

User Reviews and Reputation:
