These filters utilize ultraviolet light. As water flows through a chamber, it’s exposed to UV light, destroying bacteria, viruses, and certain pathogens. Ensuring that water is devoid of these microbial threats. Often integrated into home water purification systems, they can be installed at water entry points or under kitchen sinks.
Ion exchange filters:
Specializing in addressing hard water, these filters swap out calcium and magnesium ions for sodium ions. Beyond softening, they are also effective at reducing nitrate, arsenic and boron levels. They're particularly beneficial for homes dealing with limescale or soap scum and can often be found paired with other household water treatment systems.
Employing gravity to guide water through layers, these filters capture a wide variety of contaminants. They are particularly adept at removing chlorine, sediments, heavy metals and some PFAS compounds (with some models reducing PFAS by 100%). Being independent of electricity and elaborate plumbing, these are popular choices for countertop units in homes and travel such as camping.
A purification system mimicking the natural process of evaporation and condensation, distillers boil water and then capture the clean steam. This method effectively separates water from contaminants such as heavy metals, chlorine, herbicides, fluoride, select pharmaceuticals, VOCs and sediment, which are then left behind in the boiling chamber. The result is pure water that's condensed into a separate container. Given their compact design, these units are commonly placed on kitchen countertops.
