TURN ANY CARAFE INTO A FILTER

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.

FUNNELPolished stainless steel, 1 L / 34 fl oz capacity. An integrated mechanical drip stop lets water through only when the funnel is placed on a vessel. Designed to sit on the neck of a wine bottle, and anything larger.
FILTERLasts 50 gallons, or about 3–6 months depending on use and water conditions. Filtering time varies with your local water — expect around 5 minutes for 1 L / 34 fl oz with a new filter. For contaminant removal, we are in the middle of testing at third-party labs; results are published as they arrive. One thing we already know: the water tastes better.
STANDIncluded in the funnel kit. Holds the funnel for storage, while you fill it, or when you want to pause filtering.
CARAFEBorosilicate glass, 1 L / 34 fl oz. Handles cold and hot drinks like tea. Comes with a solid silicone plug.

HOW TO USE

TEST DATA

BELON is tested to NSF/ANSI standards through IAPMO R&T, an accredited certification body. These are the performance tests certification is built on. They measure how well the filter actually filters. Every report is published here in full.

BELON is not yet certified. 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. It takes time and real investment.

WHO RUNS THESE TESTS

NSF/ANSI standards are public. Three accredited bodies test and certify against them: NSF International, IAPMO R&T and WQA. A certification from any of the three carries the same standing. BELON's testing runs through IAPMO R&T.

Every report is published here in full.

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
