Which Filter Is Best for Drinking Water?

por Dr. Jonathan Doyle - Updated March 26, 2024
To prevent waterborne diseases and preserve good health, clean and safe drinking water must be constantly available. Luckily, you can protect yourself and your family from these harmful substances in the water by purchasing a durable water purifier that meets local regulations and standards for water quality.
Although there are many drinking water purifiers on the market, not all can satisfy your individual needs. Hence, to help you cross the hurdle of searching and deciding which one’s best for you, we have compiled a list of the top 5 best filters for drinking water.

What Are Water Filters and How Do They Work?

Water filters remove impurities, pollutants, and undesirable elements from water. They help you ensure the water meets a certain quality standard for consumption or other uses. These filters use many purification methods to purify water.
One example is the use of activated carbon filters, which is one of the most common forms of water filters. It has a large surface area and numerous tiny holes, which capture and absorb pollutants. This technique successfully removes organic contaminants, chlorine, and volatile organic compounds (VOCs), which improves the taste and odor of water.

Another popular filtration method is a reverse osmosis water filter . Water flows across a semipermeable membrane, which allows only water molecules to pass and avoids contaminants such as germs, viruses, and dissolved minerals. Reverse osmosis effectively produces high-purity water for residential and industrial purposes. Some filters employ ceramic materials with extremely fine pores to physically block larger particles, silt, and microbes.
UV (ultraviolet) water purifiers remove contaminants from water by destroying the germ DNA. Although it does not eliminate particles or chemicals, it will help you remove bacteria, viruses, and other pathogens. Lastly, the Ion exchange filters replace undesirable ions in water with more appropriate ones. These filters often soften water by exchanging calcium and magnesium ions for sodium ions, resulting in lower water hardness. Some filters adopt only one of these purification systems, while others combine two or more. The more systems combined in a filter, the more effective it would be at purifying your water, especially for drinking.
