The Alexapure Pro water filter is an elegant stainless steel countertop system that doesn’t need plumbing or electricity to function – instead using gravity feed technology, its filters remove or reduce over 200 contaminants from your water source.
Filtration processes typically take an hour in gravity-fed systems. Additionally, cleaning chambers regularly is advised in order to avoid clogs in your filter system.
NSF/ANSI 42 & 53
NSF International is a non-profit organization founded in 1944 to enhance global human health and safety. They create public health standards and certifications for food, water, consumer products and manufacturing processes – such as NSF/ANSI 42 which specifies that filters should significantly reduce or remove aesthetic contaminants such as chlorine and chloramines in drinking water for greater visual appeal and reduced likelihood of illness.
Most bestselling water filters meet NSF/ANSI 42 and 53 standards, such as both the Big Berkey and Alexapure Pro models. Both use gravity filtration to filter water efficiently; however, Big Berkey outshines Alexapure Pro in terms of eliminating harmful contaminants and heavy metals from drinking water.
The Big Berkey’s stainless steel system consists of two tanks; untreated water is stored in one and purified water is held in another. Filter elements should be changed every 3-6 months and each pair can filter up to 6,000 gallons. Customers praise its comprehensive contaminant removal and improved water taste; some critics do note a rubber taste due to rubber components inside its filters.
NSF/ANSI 58
NSF/ANSI 58 is the standard that applies to reverse osmosis drinking water treatment systems. It outlines requirements for reducing total dissolved solids (TDS) as well as claims for additional contaminant reduction, material safety issues related to contact with drinking water through formulation review, extraction testing and structural integrity tests, as well as material requirements when used directly with drinking water sources.
The Big Berkey and Alexapure Pro are both certified to safely remove various contaminants such as bacteria; heavy metals (lead, copper and chromium VI); volatile organic compounds; herbicides; common chemicals like chlorine and chlorine dioxide as well as emerging contaminates such as pharmaceutical drugs.
NSF International (formerly National Sanitation Foundation) is an independent third-party organization that sets public health standards and certifications for food, water and consumer products. Working closely with ANSI (American National Standards Institute), these standards are developed jointly. Therefore you may see both organizations listed when searching NSF listings; their missions share one goal to enhance global health, environment and prosperity through their efforts.
NSF/ANSI 61
NSF/ANSI 61 is an internationally recognized standard that sets minimum health effect requirements for chemical contaminants and impurities that could indirectly contaminate drinking water from components or materials used in drinking water systems, such as plumbing devices, pipes, mechanical devices, non-metallic potable water materials and protective barrier materials. NSF/ANSI 61 has become mandatory across 49 US states and 11 Canadian provinces/territories.
The NSF/ANSI 61 certification process is very rigorous. It involves product formulation submission, manufacturer interviews, plant inspections and extensive independent testing at NSF laboratories. Furthermore, its open and consensus-based process gives credibility to this standard which has become the go-to standard in over 140 countries worldwide – making NSF/ANSI 61 an integral component of marketing and branding strategies for companies worldwide.
NSF/ANSI 62
The Alexapure Pro stands out from other filters by featuring an easy-to-clean ceramic hybrid shell, essential as minerals from untreated water may leave behind deposits on its exterior that clog it. To maintain optimal performance and prevent buildup on future reuse, it is advised that this filter be rinsed with clean water prior to being reused.
The Alexapure Pro can remove over 200 contaminants, such as fluoride, barium, chromium VI mercury PFOA turbidity lead bacteria and viruses from water supplies.
Many customers have praised the Alexapure Pro for its thorough contaminant removal, leading to improved water taste and better health outcomes. While some customers have mentioned a rubbery taste in their water after filtering, this may be caused by rubber components inside the system that could potentially be replaced with silicone parts instead. Overall, however, the Alexapure Pro remains an excellent option for anyone looking for safe drinking water filter solutions.
