Mechanical Filtration
Mechanical filtration is akin to sifting through flour to remove lumps; only in this case, the flour is water, and the lumps are particulates. This type of filtration physically strains water to remove turbidity, or the presence of suspended particles. This is frequently the first stage in a multi-step filtration process since it protects finer filters down the line from clogging prematurely.
Most mechanical filters are rated based on the size of particles they can remove, measured in microns. Common examples include mesh screens or spun fibers that act as a sieve. Regular maintenance of mechanical filters is essential as the trapped particulates can cause reduced water flow and diminished filtration efficiency.

Activated Carbon Filtration
Carbon filtering is a method that utilizes pieces of activated carbon to remove contaminants and impurities, utilizing chemical adsorption. Every particle, or granule, of carbon provides a large surface area, or pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter media.
One of the most noteworthy aspects of activated carbon is its ability to remove chlorine, thus improving taste and odor in tap water. Some carbon filters are also designed to remove lead, mercury, and volatile organic compounds (VOCs). However, they are not effective for minerals, salts, and dissolved inorganic compounds. Therefore, carbon filters often serve as a complementary stage in a more extensive filtration system.
Reverse Osmosis
Reverse osmosis (RO) operates on a more intricate principle, where water is forced through a semi-permeable membrane that blocks particles larger than water molecules. This process effectively demineralizes water, removing dissolved substances that mechanical or carbon filters can’t catch, such as arsenic, fluoride, and perchlorates.
RO systems generally incorporate multiple stages, including pre-filters and post-filters. Sometimes, these systems include a UV light for disinfection purposes. While reverse osmosis is highly effective, it can produce a significant amount of waste water, and the membranes require regular replacement.
Ion Exchange
Ion exchange is a process typically used to soften water by replacing undesirable ions with ones that do not cause hardness in water. Most commonly in home water softening systems, calcium and magnesium ions, which may cause scale buildup, are replaced with sodium or potassium ions.
This process can also remove a variety of other substances such as iron, radioactivity, heavy metals, and nitrates. One of the limitations of ion exchange is the periodic need to recharge the resin with more sodium or potassium, and it does not effectively remove organic contaminants, viruses or bacteria, meaning it often works best in tandem with other forms of filtration.
Ultraviolet Disinfection
Ultraviolet (UV) disinfection is a non-chemical approach to water purification that uses ultraviolet light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA. This makes the organisms unable to perform vital cellular functions or reproduce, effectively eliminating the risk of disease caused by these pathogens.

UV disinfection is particularly effective when combined with other forms of filtration that reduce the turbidity of the water, as cloudiness can shield microorganisms from UV light. While effective for bacteria and viruses, UV light will not remove any non-living contaminants from water, such as heavy metals and chemical pollutants.
