FILTER STAGES:

Stage 1: Sediment and Chlorine Reduction Filter 

  Reduces chlorine, bad taste, and odor while capturing fine particles down to 0.5 microns, including cysts like Giardia and Cryptosporidium. This filter is certified to NSF/ANSI Standard 42 and helps ensure your water is safe.

Stage 2: Submicron Filtration with Ion Exchange

  Designed for submicron filtration at 0.2 microns, this stage tackles contaminants like bacteria, viruses, and heavy metals such as lead and arsenic. The built-in silver additive further protects against bacterial growth. NSF/ANSI 42/61 certified.

Stage 3: Advanced Carbon and Nano Filtration

The powerhouse of the NomadGuard system, this filter uses advanced carbon and nanotechnology to tackle a wide range of harmful contaminants. It has been shown in third-party lab tests to reduce chloramines, lead, fluoride, and volatile organic compounds (VOCs), which can affect both water safety and taste. Tested to stringent ANSI/NSF standards, and will effectively address PFAS, a class of chemicals that many filters on the market struggle to address. It also effectively removes cysts like Giardia and Cryptosporidium, along with pharmaceutical residues and other emerging contaminants. With its high surface area and minimal pressure drop, this filter ensures consistent, reliable, proven performance, making it a critical part of the system’s multi-stage approach to delivering safer, healthier water. Tested To: NSF/ANSI Standard 53 Cyst Reduction. Meets P231 Protocol.

Stage 4: Carbon Polishing Filter

This final stage is designed to enhance water taste and ensuring its overall quality. Using premium coconut-shell carbon, this filter works to reduce any remaining chlorine, chloramines, and volatile organic compounds (VOCs) that might still be present after the initial filtration stages. By maximizing contact time with the water, it efficiently removes lingering contaminants that can impact flavor, leaving your water tasting clean, crisp, and refreshing.
