OUR FILTER SYSTEM
BELON works differently from other gravity filters: there is no plastic tank. The funnel filters directly into the carafe or bottle you serve from.
The funnel comes with a filter and its stand. The carafe is optional. If you already own a carafe you love, use it.
HOW TO USE
TEST DATA
These are test results, not certifications. The tests follow the same NSF/ANSI protocols certifiers use, and they cover the performance portion of certification — how well the filter actually filters.
Full certification adds materials safety testing on every component that touches water, review of every claim we publish, factory audits, and annual re-verification. We plan to certify BELON fully. It takes time and real investment.
WHO RUNS THESE TESTS
NSF/ANSI standards are public standards. Three accredited bodies test and certify against them — NSF International, IAPMO R&T, and WQA — and a certification from any of the three carries the same standing. Our testing runs through IAPMO.

MICROPLASTICS
Tested in accordance with NSF/ANSI 42, Class I particulate filtration — particles 0.5 to <1 micron, smaller than any particle defined as a microplastic. This is the protocol NSF designates as the basis for microplastics reduction claims.
Test date: August 2026
Reduction level: 99.7% or greater, across two production units.
Testing Lab: BCS Laboratories, Gainesville, FL (ISO 17025) · Commissioned through IAPMO
