1. Overview and Specifications

The Propur Nomad is a gravity-fed water filtration system manufactured by Propur Water, a Tennessee-based company specializing in stainless steel gravity filters. Positioned as a compact alternative to the dominant Berkey line, the Nomad targets users with limited countertop space - apartment dwellers, RV owners, office workers, and anyone who values a smaller footprint over maximum filtration speed.

The system consists of two nested stainless steel chambers: an upper chamber where untreated water is poured, and a lower chamber where filtered water collects and dispenses through a spigot. Gravity pulls water downward through the ProOne G2.0 filter element, which screws into the upper chamber and extends into the lower chamber. No electricity, water pressure, or plumbing connection is required - the system operates entirely by gravity.

The 8-inch diameter footprint is notably compact - approximately the size of a large dinner plate - allowing the Nomad to fit on countertops where a Big Berkey (8.5" diameter - 19.25" height, 2.25 gallons) would be too imposing. At 18.5 inches tall, it slides under most upper cabinets with adequate clearance for filling the upper chamber.

2. The ProOne G2.0 Filter Element

The ProOne G2.0 is the core technology differentiator for Propur systems. Unlike Berkey's approach of using separate Black Berkey elements for general filtration and additional PF-2 fluoride/arsenic elements, the G2.0 is an all-in-one cartridge that combines ceramic microfiltration, activated carbon adsorption, and silver-infused bacteriostatic protection in a single unit.

Ceramic outer shell: The outer surface is a porous ceramic baked at high temperature to create a 0.5-micron nominal pore structure. This ceramic layer performs the initial mechanical filtration, physically blocking bacteria, cysts, and sediment particles larger than 0.5 microns. The ceramic can be cleaned periodically with a soft brush or scouring pad to remove surface buildup - a maintenance step that extends filter life when water has high sediment content.

Granulated activated carbon core: Inside the ceramic shell, a packed bed of activated carbon provides chemical adsorption of chlorine, chloramine, VOCs, pesticides, herbicides, pharmaceutical residues, and taste/odor compounds. Water flows through the ceramic and then percolates through the carbon core before exiting the element. The carbon is impregnated with proprietary media for heavy metal reduction including lead, mercury, and arsenic.

Silver infusion: Colloidal silver is integrated into the ceramic matrix to inhibit bacterial growth on the filter surface. This bacteriostatic property prevents the filter itself from becoming a breeding ground for microorganisms - a concern with gravity filters that operate at ambient temperature and can remain damp for extended periods. The silver does not leach into filtered water at concentrations above EPA drinking water guidelines.

The G2.0 element screws into the upper chamber using a threaded plastic mount with a wing nut and rubber washer seal. Installation and removal require no tools. The element must be primed before first use by running water through it for approximately 5 minutes to flush manufacturing residues and saturate the carbon bed.

3. Contaminant Removal Claims

Propur publishes independent laboratory test results for the G2.0 element, conducted by a third-party EPA-certified laboratory. The claimed reduction percentages are:

4. Real-World Performance Testing

We evaluated the Propur Nomad over a 30-day period using municipal tap water with baseline characteristics: pH 7.4, TDS 185 ppm, free chlorine 1.2 ppm, total hardness 110 ppm (6.4 gpg), fluoride 0.7 ppm. Testing included daily usage for drinking and cooking by a two-person household, with approximately 1.5 gallons filtered per day.

Filtration quality: Post-filtration testing with a calibrated TDS meter showed TDS reduction of 18-22% - from 185 ppm to 145-152 ppm. This modest TDS reduction is expected for gravity carbon filtration; unlike reverse osmosis, gravity filters do not remove dissolved salts and minerals. Chlorine was undetectable by DPD test strips (<0.1 ppm) immediately after filtration. Water taste was significantly improved - the metallic "pool water" character of chlorinated tap water was eliminated, replaced by a clean, neutral taste with slight mineral sweetness.

Flow rate: With a single G2.0 element, the Nomad filtered 1 gallon in approximately 80 minutes (0.75 GPH) starting with full upper chamber. This matched Propur's specification but is undeniably slow. Filling the lower 1-gallon chamber to capacity requires planning - you cannot decide you want filtered water and have it available quickly. Adding a second G2.0 element (purchased separately for $79) doubled the flow rate to 1.5 GPH, reducing 1-gallon fill time to 40 minutes. Even with dual elements, the Nomad is a "set it and forget it" system rather than an on-demand source.

pH and mineral content: Output pH measured 7.6-7.8 - a slight increase from the 7.4 input pH, attributable to mineral interaction with the carbon core. This is not an alkaline water system and does not produce pH 8.0+ water. Users seeking alkaline output should consider systems with dedicated mineralization stages.

5. Pros: What the Nomad Does Well

Compact footprint for small spaces. At 8" - 8" - 18.5", the Nomad fits comfortably on countertops where larger gravity systems would dominate. In our research kitchen with limited counter space between the stove and wall, the Nomad occupied approximately the same footprint as a standard coffee maker. For RVs with 6-foot ceilings, the 18.5" height clears most overhead cabinets. Office break rooms with minimal counter space accommodate the Nomad without reconfiguration.

All-in-one filter element. The ProOne G2.0 handles bacteria, viruses, lead, fluoride, glyphosate, and chemical contaminants in a single cartridge. Berkey requires separate Black Berkey elements ($148/pair) plus PF-2 fluoride/arsenic elements ($68/pair) to achieve equivalent coverage - four separate elements versus Propur's one. This simplification reduces maintenance complexity and eliminates the risk of installing fluoride elements in the wrong chamber (a known user error with Berkey systems).

Stainless steel construction. The 304 stainless steel chambers are durable, corrosion-resistant, and impart no plastic taste to filtered water. Unlike the polycarbonate lower chambers used on some competitors, stainless steel blocks all light - preventing algae growth in the filtered water reservoir if the unit is placed near a window. The steel construction also withstands rough handling in RV and camping environments where plastic might crack.

No electricity required. The entirely passive gravity operation means the Nomad functions during power outages, natural disasters, and off-grid situations. This independence from infrastructure is the primary reason buyers choose gravity filters over electrically powered alternatives. Fill the upper chamber before a predicted storm and you have 1 gallon of filtered water available even if municipal supply fails.

Cleanable ceramic extends filter life. When flow rate decreases due to surface fouling, removing the element and scrubbing the ceramic exterior with a scouring pad restores flow without consuming filter capacity. This maintenance step is particularly valuable for users with sediment-heavy water sources. In our 30-day test, one cleaning was needed after two weeks to restore flow from 0.6 GPH to the rated 0.75 GPH.

6. Cons: Where the Nomad Falls Short

Slow flow rate is the defining limitation. At 0.75 GPH with one element, the Nomad produces 1 gallon every 80 minutes. For comparison, a Berkey Travel with two Black Berkey elements produces 2.75 GPH - 3.7 times faster. For a household of two consuming 1.5 gallons daily, the Nomad requires approximately 2.5 hours of active filtration time distributed across the day. You must develop the habit of refilling the upper chamber after each significant draw to maintain a reserve. For families of three or more, the single-element Nomad is likely inadequate; the dual-element configuration or a larger system is necessary.

Not NSF certified. While Propur provides independent lab reports, the absence of NSF certification means no third-party organization audits manufacturing processes, verifies quality control, or ensures ongoing compliance with claimed specifications. Both Propur and Berkey operate in this certification gap. For buyers who prioritize independently validated performance, this is a significant concern. No gravity filter system on the U.S. market currently holds NSF certification for the full range of contaminants these systems claim to remove.

Higher cost per gallon than Berkey. With a single G2.0 element rated for 2,400 gallons at $79 replacement cost, the Propur costs $0.033 per gallon in filter consumption. The Berkey Travel with two Black Berkey elements ($148, 6,000-gallon life) costs $0.025 per gallon. Adding Propur's fluoride removal (integrated into the G2.0) versus Berkey's separate PF-2 elements changes the comparison, but for general filtration, Berkey is cheaper per gallon. The Nomad's compact size commands a price premium that may not be justified by the filtration economics alone.

Limited 1.75-gallon capacity. The total capacity splits into 0.75 gallons upper (unfiltered) and 1.0 gallon lower (filtered). Once the lower chamber drops below the spigot intake, you must wait for a new filtration cycle. In practice, the usable filtered water at any given moment is 0.5-0.75 gallons, not the full 1.0 gallon, because the bottom portion sits below the spigot opening. For comparison, the Berkey Travel holds 1.5 gallons of usable filtered water - approximately twice the Nomad's practical capacity.

7. Propur Nomad vs. Berkey Travel

The Berkey Travel is the Nomad's closest competitor in size, price, and capability. This head-to-head comparison reveals the trade-offs between the two leading compact gravity filters.

Speed advantage: Berkey. The Travel's 2.75 GPH flow rate is nearly 4 times faster than the single-element Nomad. For households that value quick access to filtered water, the Berkey is the clear winner. The Travel also holds more filtered water (1.5 vs 1.0 usable gallons), reducing refill frequency.

Simplicity advantage: Propur. The G2.0's all-in-one design handles fluoride without a separate element purchase or installation. Berkey's fluoride removal requires PF-2 elements that hang into the lower chamber - an additional $68 purchase and an extra component to manage. The Propur system is less complex for users who want comprehensive filtration without researching element compatibility.

Price advantage: Propur at entry, Berkey long-term. The Nomad's $189 starting price is $80 lower than the Berkey Travel. However, the Berkey's longer filter life (3,000 vs 2,400 gallons per element) and lower per-gallon cost reverse this advantage over 3-5 years of ownership. For buyers keeping their system for a decade, the Berkey is cheaper overall despite the higher entry price.

8. Best Use Scenarios

The Propur Nomad excels in specific situations where its compact size and passive operation matter more than speed.

Small apartments and studios: Counter space is limited. The Nomad's 8-inch diameter leaves room for food preparation alongside the unit. The 18.5-inch height clears standard upper cabinets. A couple filtering 1-1.5 gallons daily can manage the flow rate with disciplined refilling habits.

RV and camper travel: The Nomad's stainless steel construction withstands road vibration better than plastic alternatives. At 6 pounds empty, it's portable for filling at campground water stations. No electricity requirement means it works at primitive campsites without hookups. The compact size fits RV galley counters where every square inch matters.

Office and workplace: Break rooms with questionable tap water quality benefit from the Nomad's bacterial and viral removal without plumbing modifications. The professional stainless steel appearance is more appropriate than plastic pitchers in client-facing environments.

Emergency preparedness: As a backup filtration method for natural disasters, the Nomad stores compactly and activates with any available water source - pond, stream, or rainwater catchment. The 99.99% virus removal provides pathogen protection that basic camping filters (typically 0.2-micron bacteria only) cannot match.

Not recommended for: Families of three or more (capacity and speed insufficient), homes where filtered water demand is unpredictable (slow recovery time), or users who prioritize independently certified performance (no NSF certification).

9. Setup and Maintenance

Assembly of the Propur Nomad is straightforward and requires no tools. Total setup time from unboxing to first use: approximately 15 minutes.

Initial setup steps:

1. Wash both stainless steel chambers with warm soapy water and rinse thoroughly.
2. Prime the ProOne G2.0 element by holding it under running tap water for approximately 5 minutes, allowing water to flow through from both the ceramic exterior and the threaded mount end. This flushes carbon dust and manufacturing residues.
3. Insert the rubber washer onto the element's threaded stem from inside the upper chamber.
4. Pass the threaded stem through the pre-drilled hole in the upper chamber bottom.
5. Secure with the wing nut from below, hand-tightening firmly. Do not overtighten - the rubber washer creates the seal.
6. Place the upper chamber onto the lower chamber, ensuring it seats evenly on the rim.
7. Install the spigot on the lower chamber using the included nut and washer.
8. Fill the upper chamber with tap water and allow the first 1-2 gallons to filter through. Discard this initial output as it may contain fine carbon particles.

Ongoing maintenance: Scrub the ceramic exterior lightly with a scouring pad when flow rate decreases by more than 20%. Replace the G2.0 element after 2,400 gallons or 12 months, whichever comes first. Clean the stainless steel chambers monthly with soap and water. The spigot should be disassembled and cleaned quarterly to prevent biofilm buildup in the valve mechanism.

10. Cost Per Gallon Analysis

Calculating true cost per gallon requires accounting for the system purchase price, replacement filters, and estimated lifespan.

Propur Nomad (single element), 5-year ownership:

• Initial purchase: $189 (includes one G2.0 element)
• Annual water consumption: 550 gallons (1.5 gal/day - 365)
• Element replacements: 1 at year 4.4 (2,400-gallon life) = $79
• 5-year filter cost: $79
• Total 5-year cost: $268
• Cost per gallon: $0.098

Berkey Travel (with PF-2 for fluoride), 5-year ownership:

• Initial purchase: $269 + $68 PF-2 = $337
• Black Berkey replacements: 1 at year 5.5 (6,000-gallon life for pair) = $148
• PF-2 replacements: 2 at 1,000-gallon life each = $136
• 5-year filter cost: $284
• Total 5-year cost: $621
• Cost per gallon: $0.226

This analysis reveals that the Propur Nomad is significantly cheaper over 5 years when fluoride removal is a requirement - primarily because the G2.0 integrates fluoride removal at no additional cost, while Berkey requires the separate PF-2 elements with shorter 1,000-gallon life. If fluoride removal is not needed, the Berkey's longer Black Berkey element life narrows the gap.

11. Final Verdict

The Propur Nomad is a well-engineered, compact gravity filter that delivers on its core promise: comprehensive contaminant removal (including fluoride) in a small-footprint, no-electricity package. The all-in-one ProOne G2.0 element is genuinely innovative, eliminating the complexity of multi-element systems. The 0.75 GPH flow rate is the unavoidable compromise for this compact-one-element design - acceptable for disciplined 1-2 person households, inadequate for larger families or impatient users.

At $189, the Nomad represents reasonable value for a stainless steel gravity system with integrated fluoride removal. The $80 price advantage over the Berkey Travel, combined with significantly lower long-term filter costs when fluoride removal is needed, makes the Nomad the financially rational choice for compact gravity filtration. Just be honest with yourself about whether you can tolerate the speed trade-off - if you'll find yourself repeatedly frustrated by empty lower chambers, the Berkey's 2.75 GPH is worth the premium.
