Our take on the Ultraflo Universal 10 Replacement Water Filter For Under Sink Portable Systems 2 Filters

The UltraFlo is a 10-inch replacement cartridge for under-sink, whole-house and portable water systems, sold as a two-pack. Its nano-alumina fiber media uses electroadsorption rather than plain mechanical straining, and Sagan says it is independently tested to remove up to 99.9999% of bacteria, 99.99% of viruses and parasites, and to reduce lead and other heavy metals. Each cartridge is rated for about 2,000 gallons and is made in the USA. It suits RV, van and motorhome owners and anyone replacing a cartridge in a standard 10-inch sump housing. Against ordinary carbon block filters, it claims far higher pathogen removal, but it is a cartridge, not a system, and it fits only housings that take 10-inch filters.

About the Ultraflo Universal 10 Replacement Water Filter For Under Sink Portable Systems 2 Filters

The UltraFlo Universal 10" Replacement Water Filter removes bacteria, viruses, parasites and lead, and reduces heavy metals and other waterborne toxins. It is independently tested and certified to remove up to 99.9999% of bacteria such as E. coli, 99.99% of viruses, and 99.99% of parasites such as Cryptosporidium and Giardia. It is made in the USA.

It fits most under-sink sump and whole house filtration systems, and it suits RVs, vans and motorhomes. It is also a replacement filter for the UltraFlo under sink filter system and the UltraFlo Portable Water Filter System.

The filter media works by electroadsorption, not mechanical filtration. The positively charged media attracts and holds contaminants, down to the size of viruses, as water contacts it. The media is made of non-woven, nano-alumina coated glass fibers that contain powdered activated carbon and silver for antimicrobial protection. It sits between layers of spunbond polyester that give the pleated media strength.
