For this post, we are continuing our April 2020 Spotlight, “Multipure’s Aqualuxe: Cutting Edge Water Treatment” by discussing what really elevates the Aqualuxe above and beyond its drinking water filtration peers: NSF-certified treatment of bacteria and viruses in drinking water, in addition to NSF-certified treatment of the broadest array of aesthetic contaminants, health contaminants, and emerging compounds/incidental contaminants.

When it comes to microbiological purification – the removal of bacteria, viruses, and live cysts from water – not all filters are the same, and not all drinking water treatment products are even effective at removing microbial contaminants. Here are some of the product types and methods, and their advantages and disadvantages.

  • Chlorination: Performed by most municipalities at the local water treatment center, this method involves the addition of chlorine into the water to kill most microorganisms before the water is transported through miles of pipes to your home.
    • Advantage: Does not require any effort by the consumer.
    • Disadvantages: Requires regular addition of chemicals (chlorine) into the water. Takes time for the chlorine to kill the microorganisms. Chlorine can form harmful disinfection byproducts in the water, some of which are carcinogenic. Chlorine negatively affects the taste and odor of the water. Does not treat non-microbial contaminants in the water, like lead, asbestos, and particulate matter.
  • Boiling: One of the oldest and simplest methods of treating microbial contaminants in drinking water, boiling only requires power and heat – once the water boils, most of the bacteria and viruses in the water are killed.
    • Advantage: Simple process that does not require chemical additives.
    • Disadvantages: Requires a source of power/heat. Takes time to boil the water. Filtered water capacity is limited to the size of the water container – generally produces only a small amount of filtered water at a time. Does not treat non-microbial contaminants in the water (e.g., lead, arsenic, or disinfection byproducts), and by boiling the water, it can make these contaminants more concentrated in the remaining water.
  • Filtered Pitchers & Faucet-Mount Filters: Neither filtered water pitchers nor faucet-mount filters are effective in removing bacteria and viruses in drinking water. Both rely on granular activated carbon (GAC) as their filtration method. These types of filters are adequate at treating chlorine or large particulate matter in water. These types of filters are not effective at purifying drinking water at the microscopic sizes of bacteria and viruses.
    • Advantage: Relatively inexpensive and easy to install or use.
    • Disadvantages: Does not remove bacteria, viruses, or live cysts from the drinking water. Most filtered pitchers and faucet-mount filters have very limited filtration capabilities, and are typically limited to the treatment of chlorine and large particulate matter in water. Small filter size means that filters must be changed frequently – sometimes as often as once a month.
  • Ultraviolet Systems (UV): Ultraviolet systems use UV light radiation to kill most microorganisms in the water.
    • Advantages: Does not require chemical additives. With enough power, disinfection can occur relatively quickly.
    • Disadvantages: Requires continuous power for operation. Requires particulate-free water for the UV rays to work effectively. Does not treat non-microbial contaminants in the water, and generally must be used in conjunction with another type of filter to ensure the water is clean enough for the UV treatment to work.
  • Reverse Osmosis (RO): Reverse Osmosis systems force the drinking water through a series of filters and ultimately through the tiny pores in an RO membrane to mechanically filter out contaminants.
    • Advantages: Filters all contaminants larger than the membrane pore size, including bacteria, viruses, and cysts. A series of carbon block pre-filters reduce the presence of non-microbial contaminants in the water (e.g., lead, disinfection byproducts, volatile organic chemicals, etc.).
    • Disadvantages: High installation complexity. Because it utilizes multiple filters, there are many filters to change on a regular basis – a typical RO system may use 4-6 separate filter cartridges, adding to the long-term cost of the system. Produces a considerable amount of wastewater during operation – a typical RO system wastes 3-5 gallons of water for each 1 gallon of filtered water produced. Requires significant inflow water pressure for effective operation. The RO process takes time – 2 to 4 hours to fill a 2.8 gallon tank – to fill the filtered water reservoir. Once the reservoir is depleted, it takes another 2 to 4 hours before it is refilled with filtered water; therefore, available clean water is limited to the reservoir size. Removes the healthful minerals that impart flavor to the drinking water.
  • Multipure Aqualuxe: The Aqualuxe uses Multipure’s proprietary PureBlock Technology to mechanically filter microbial contaminants in the water. In conjunction with Multipure’s carbon block technology, the Aqualuxe is NSF-certified to treat the widest variety of drinking water contaminants, both organic, and inorganic.
    • Advantages: Fast filtration process – does not require processing time or a water reservoir. Does not require chemical additives or leach chemicals into the water. Does not require power. Does not waste water. There is only one filter to change approximately once a year. Does not remove the healthful minerals – like calcium and magnesium – that impart flavor to the drinking water.
    • Disadvantages: PureBlock technology is unique to the Multipure Aqualuxe (off-brand filters will not afford the same capabilities).

In addition to the technical and performance differences between the various drinking water treatment systems and methods, a major feature that elevates the Aqualuxe above its peers is its NSF certification for Standard P231 (Microbiological Purifier). This means that the Aqualuxe has been third-party tested and verified for its performance in removing bacteria, viruses, and live cysts from drinking water. In fact, the Aqualuxe has been certified to remove 99.9999% of bacteria, 99.99% of viruses, and 99.9% of live cysts from drinking water. This is in addition to its NSF certifications for Standard 42 (Aesthetic Contaminants), 53 (Health Contaminants), and 401 (Emerging Compounds/Incidental Contaminants).

This is why we tout the Aqualuxe as “cutting edge water treatment,” because it is not only the more effective, more efficient, and more convenient water purification method, but it is NSF-certified to treat the broadest range of drinking water contaminants. In a time where the dangers of viral contamination are at the forefront of public conscience, Multipure’s Aqualuxe gives you the peace of mind that comes from knowing your family’s drinking water is protected.
