When it comes to microbiological contaminants in water – bacteria, viruses, and live cysts – there are a few methods in general use to render the water safe for consumption. These include boiling or distillation, chemical disinfection, and ultraviolet (UV) treatment. Multipure’s PureBlock offers a drinking water purification method superior to all of them. Let’s take a closer look at these methods.

Boiling is one of the oldest forms of water treatment, in which heat is applied to the water source to either destroy microorganisms in the water or vaporize the water entirely and condense it back into liquid (a process known as distillation). While this can be effective, it also requires energy to provide the heat, and requires the time to heat, boil, and cool the water for consumption. In addition, certain contaminants remain in the water, such as metals, salts, and some volatile organic compounds (VOCs). Because its primary mechanism is only the destruction or removal of microorganisms in the water, it is a good purifier but does not remove the contaminants in the water.

Chemical disinfectants are commonly used by municipalities to purify drinking water, typically through the addition of chlorine or chloramine to the municipal water supply. While chlorine and chloramine can effectively treat the presence of most bacteria and viruses, there still exist chlorine-resistant strains of bacteria, virues, and cysts that are not affected by the presence of these disinfectants. In addition, it requires time for chemical disinfectants to adequately purify the water, and there exists the possibility of harmful disinfection byproducts to be created inadvertently. Finally, chemical disinfectants generally do not affect non-microbiological contaminants such as arsenic, lead, or other heavy metals. These disinfectants also tend to negatively affect the taste and odor of the water.

Ultraviolet purification (UV) is a third method of microbiological water treatment, in which ultraviolet light radiation is applied to the water to destroy bacteria, viruses, and cysts. With a strong enough UV source and power, disinfection can occur relatively quickly. On the other hand, UV purification does nothing to treat non-microbiological contaminants such as heavy metals, pesticides, or herbicides, and their effectiveness is negatively impacted by cloudiness or turbidity in the water, which can block the UV rays. As such, UV treatment almost requires an additional pre-filter to treat the water prior to the UV exposure.

Now, let’s examine Multipure’s NSF-certified (NSF Standard P231) PureBlock technology in comparison. Built upon Multipure’s powerful carbon block filter technology, PureBlock utilizes both mechanical and adsorption-based filtration to remove bacteria, viruses, and live cysts from drinking water. It does not require the water to be treated and stored prior to drinking (such as the case with boiling or chemical disinfection) or for external power (such as for UV purification), and because it is built upon Multipure’s existing carbon block technology, it not only removes the presence of microbiological contaminants, but it also treats a broad spectrum of other contaminants, including arsenic V, asbestos, chlordane, cysts, lead, mercury, MTBE, PCB, radon, toxaphene, turbidity, VOCs, microcystin, PFOA, and PFOS, as well as aesthetic contaminants, microplastics, and pharmaceuticals. It represents a comprehensive water treatment solution, without the need for chemical additives or power, and without pre-treatment time and water reservoirs.

Ultimately, Multipure’s revolutionary PureBlock – and the Aqualuxe Drinking Water System that utilizes it – offers a powerful, effective, and efficient solution to treating a broad array of harmful contaminants in your drinking water, reinforcing our claim that Multipure is The Best in Water Filtration.
