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

(1)
Fill the funnel with tap water
(2)
Place on top of any bottle or carafe
(3)
A drip stop lets you pause midway
(4)
Enjoy freshly filtered water

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.

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
