Our take on the Ultraflo Universal 10 Water Filter Replacement

The Sagan Life UltraFlo Universal is a 10-inch replacement water filter cartridge for standard under-sink housings and RV or van water systems. It uses patented Nano Fiber media that works by electroadsorption, a positively charged field that attracts and holds contaminants rather than just screening them out. Sagan rates it to remove 99.9999% of bacteria, 99.99% of viruses and 99.99% of parasites such as Cryptosporidium and Giardia, and to reduce heavy metals like lead, across up to 2,000 gallons. That capacity and the pathogen claims put it ahead of plain carbon block cartridges, which mainly handle taste, odor and chlorine; it suits home under-sink use and RV, van or motorhome owners who want drinking water from uncertain sources.

Best forRV, van and motorhome owners filling from campground or unknown waterHome under-sink filtration where pathogen removal mattersLong trips and off-grid use that need a high-capacity cartridgeOwners of Sagan UltraFlo kits and Survival Water Filter systems
Pros
  • Very high stated removal rates for bacteria, viruses and parasites
  • Also reduces heavy metals such as lead
  • Long 2,000-gallon capacity between replacements
  • Fits most standard 10-inch under-sink housings and RV systems
  • Made in the USA
Cons
  • Electroadsorption media needs the housing and flow it was designed for; check compatibility before buying
  • No stated micron rating or certified test standard in the product details
  • Does not soften hard water or remove dissolved salts
  • Replacement interval depends on water quality, so dirty sources shorten life

About the Ultraflo Universal 10 Water Filter Replacement

The Sagan Life UltraFlo Universal 10" Replacement Water Filter fits most standard under-sink water filter housings and RV systems. It also fits the Sagan UltraFlo Water Kit and Survival Water Filter System. It can be used in an RV, van, motorhome or home.

The filter removes 99.9999% of bacteria (such as E. coli), 99.99% of viruses and 99.99% of parasites (such as Cryptosporidium and Giardia). It also reduces heavy metals such as lead. It purifies up to 2000 gallons of water.

It uses patented Nano Fiber Technology, which works by electroadsorption rather than mechanical filtration. The filter media has a positively charged field that attracts and retains contaminants, including viruses and bacteria, as water passes through. The media is made of layers of non-woven, nano-alumina coated glass fibers containing powdered activated carbon and silver for antimicrobial protection. These are sandwiched between layers of spunbond polyester for strength and durability.

Questions and answers

What does the UltraFlo filter remove?
Sagan states it removes 99.9999% of bacteria such as E. coli, 99.99% of viruses and 99.99% of parasites such as Cryptosporidium and Giardia, and reduces heavy metals like lead.
How long does one cartridge last?
It is rated for up to 2,000 gallons. How often you replace it depends on how much water you use and how dirty the source is.
Will it fit my under-sink housing?
It is built for most standard 10-inch under-sink housings and RV systems, and also fits the Sagan UltraFlo Water Kit and Survival Water Filter System. Check your housing's size and thread before ordering.
How is it different from a standard carbon filter?
Carbon block cartridges mainly improve taste and reduce chlorine. The UltraFlo uses charged Nano Fiber media that also captures bacteria, viruses, parasites and some heavy metals.
Does it need power or plumbing changes?
No. It is a drop-in cartridge for a compatible housing, so installation is the same as changing any 10-inch filter.
Does it soften hard water?
No. It targets pathogens and some metals, not the calcium and magnesium that cause hardness.
