ProOne Big+ vs Imperial Berkey: A Comprehensive Gravity Water Filter Showdown
Both the ProOne Big+ and the Imperial Berkey are heavyweight contenders in the world of gravity water filtration systems, designed to provide clean, safe drinking water without electricity or complex installation. Each unit offers 100% water efficiency and operates purely by gravity, making them perfect for residential setups, emergencies, and even outdoor adventures. Both employ multi-layer filtration media to tackle a broad spectrum of contaminants including bacteria, viruses, heavy metals, and more.
However, key differences emerge in their filtration technology, capacity, construction materials, and price, which could influence which model fits a user's lifestyle better. The ProOne Big+ brings a compact, sleek stainless steel design with a diverse array of filtration stages including ceramic, activated carbon, and antibacterial layers. The Imperial Berkey, on the other hand, is geared for higher volume users with a larger stainless steel tank and longer-lasting filters, paired with certification credentials that speak to its ultra-high level bacteria removal capabilities.
Why the ProOne Big+ Shines for Smaller Households and Purists
The ProOne Big+ impresses with its compact footprint; just 9.25 inches wide and similarly deep, making it an excellent choice for those with limited counter space. Its design cleverly combines multiple filtration technologies: a multi-stage system featuring a ceramic filter, coconut shell activated carbon, and even an antibacterial silver layer. This comprehensive approach allows the Big+ to reduce not only common contaminants like chlorine and heavy metals but also taste and odor issues, pharmaceuticals, and persistent compounds such as PFAS and PFOA (99.9% reduction). It also supports fluoride removal, an increasingly sought-after feature.
Another noteworthy aspect is its durability and craftsmanship; both the housing and filter cartridge shells are constructed from polished 304 stainless steel, which offers excellent corrosion resistance and a premium look. Installation is straightforward with a full DIY kit included, and the average setup takes about 20 minutes. Thanks to a tool-free cartridge replacement process every six months, maintenance is hassle-free and user-friendly.
Imperial Berkey: Handling Larger Families and Tough Water Demands
The Imperial Berkey stakes its claim with a robust 132 gallons per day capacity, making it well-suited for larger households (4-8 people) or even small commercial uses. With a holding tank volume of approximately 4.5 gallons, it can provide a steady flow at nearly 0.091 gallons per minute, considerably faster than the ProOne Big+, which means less waiting for your filtered water.
This model wears an industrial-style stainless steel housing but uses sturdy plastic for its cartridge housings, a possible downside for those prioritizing all-metal systems. The Berkey's filtration media is proprietary and includes granulated activated carbon and ion exchange components. Although it lacks the multi-stage labeling of the ProOne Big+, it boasts outstanding certifications such as NSF/ANSI 53 and P231, verifying its exceptional ability to remove bacteria up to 99.9999999%, alongside viruses and cysts.
Its filters have an extraordinary lifespan of up to 22,710 gallons before replacement is needed, significantly reducing maintenance frequency. Installation is also user-friendly with an included DIY kit, typically completed within 15 minutes. Another practical advantage is its compatibility with a diverse range of water sources; including river and surface water; which makes the Imperial Berkey a go-to for outdoor or emergency preparedness where water quality is variable.
While the initial cost hovers near $450, the investment pays off for those needing larger capacity and quicker dispensing speeds, with a robust manual lever that can deliver water at over 2 gallons per minute.
Quick Take
The ProOne Big+ offers a premium, compact, multi-stage filtration experience with a stainless steel body that effortlessly handles small household needs while removing an impressively wide range of contaminants. Meanwhile, the Imperial Berkey stands out for larger families and those requiring rapid, high-volume filtration, exceptional bacteria removal certifications, and long-lasting filters that lower upkeep frequency.
Bottom Line
For those prioritizing comprehensive contaminant removal, including fluoride and pharmaceuticals, in a stylish, compact system, the ProOne Big+ is a fantastic, cost-effective choice that fits smaller households and portable scenarios. Conversely, the Imperial Berkey is the better pick for users with higher water demands, requiring large capacity, fast flow, and proven superior bacteria elimination, even if that means investing more upfront and managing pricier replacement parts.
Verdict
Winner: ProOne Big+ - Offers broader contaminant removal, premium stainless steel construction, and easier maintenance tailored for smaller households at a reasonable price.
Runner-Up: Imperial Berkey - Best for larger households needing higher capacity and faster flow with unmatched bacteria removal certifications but at a higher purchase and maintenance cost.
Side by side. The numbers. The features. No drama.
We compared every major spec, design detail, and performance point between ProOne Big+ and Imperial Berkey. If you’re trying to choose the better water filtration system, this side-by-side water filtration systems review lays out what matters — and what might surprise you.
