MULTIPURE International — Las Vegas Technology Center, Corporate Headquarters and Manufacturing Facility.

Founded in 1970, Multipure is an industry leader in the manufacture and distribution of drinking water systems and compressed solid carbon block filters. Headquartered in Las Vegas, Nevada (USA), Multipure employs over 300 people, and is committed to being an eco-friendly company that provides the people of the world with the best quality drinking water at an affordable price.

Multipure was the First to be NSF certified to reduce lead, asbestos, cyst, MTBE, chloramine, toxaphene, chlordane, arsenic, and PCBs—and will be the First to meet new standards in the future.

Multipure PureBlock water filters are also the First microbiological water purifiers certified under NSF P231 for their ability to reduce potentially pathogenic bacteria, viruses, and live cysts. Not all water filtration systems can meet this standard.

You can check the NSF P231 (Microbiological Water Purifiers) listing on the official NSF website.

Multipure is the one and only manufacturer in the world certified under the following NSF standards:

  • NSF 53 (Health Effects): Certifies that the system reduces specific health-related contaminants like lead, heavy metals, asbestos, and volatile organic chemicals (VOCs).
  • NSF P231 (Microbiological Water Purifiers): Verifies complete microbiological protection, confirming the filter’s ability to purify water by removing pathogenic bacteria, viruses, and live cysts.
  • NSF 401 (Emerging Compounds): Certifies the reduction of trace, incidental contaminants that frequently show up in water systems, such as prescription drugs, over-the-counter medications, pesticides, and herbicides.
  • NSF 42 (Aesthetic Effects): Validates the reduction of non-health-related impurities that affect the water’s taste, smell, and clarity, such as chlorine, particulates, and odor.
  • NSF P477 (Cyanotoxins): Confirms the effective filtration of dangerous microcystins and cyanotoxins caused by blue-green harmful algal blooms in source water.
  • NSF P473 (PFAS/PFOA): The original baseline protocol verifying the effective reduction of dangerous “forever chemicals” (PFOA and PFOS) down to safe parts-per-trillion levels.
  • NSF P248 (Military Operations): A rigorous standard verifying microbiological water purification efficiency for military deployment and emergency preparedness use.
  • NSF 51 (Food Equipment Materials): Ensures that the plastic, tubing, and materials used inside the filtration system are completely non-toxic, safe for food and beverage contact, and won’t leach chemicals.
  • NSF 61 (Drinking Water Components): Guarantees the structural integrity and health safety of all plumbing parts, ensuring the system itself does not add harmful contaminants to your drinking water.

We use a solid carbon block filter that is considered to be the most effective method for reducing a wide range of contaminants of health concern, which may be present in the water. The carbon is compacted into a dense structure, causing every molecule of water to be forced through microscopic pores of carbon, effectively reducing pollutants. The Solid Carbon Block Filter is a replaceable cartridge designed so that it can be easily changed. Some additional advantages of the Solid Carbon Block Filter are that it does not waste water, there is no electricity required, it does not remove essential trace minerals that are beneficial to good health, it does not add salt or silver to the water; and it provides fresh, delicious, healthy drinking water.
