Reusable Pour-Over Coffee Filter Cone in 304 Stainless Steel (AISI 304 (1.4301)) is used for replacing paper filters in pour-over brewers with a double-layer stainless cone that passes coffee oils but holds back grounds. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.

Where 304 Stainless Steel Reusable Pour-Over Coffee Filter Cone Is Used
- Housewares brands: private-label reusable drippers sold alongside kettles and grinders.
- Specialty cafés: bar-side pour-over stations that cut paper consumption and waste.
- Coffee-maker OEMs: permanent filter baskets supplied in the box with drip brewers.
- Outdoor & travel gear: collapsible camping drippers where paper is a nuisance to carry.
Ordering Reusable Pour-Over Coffee Filter Cone in 304 Stainless Steel
- Cone size: Match the top diameter and height to the dripper — 01, 02 and 03 cones are not interchangeable.
- Inner mesh: A 74 µm inner layer gives a clean cup; 100 µm etched sheet brews faster with more body and fines.
- Rim & grip: Specify a rolled SS304 rim for free-standing use or a silicone grip ring for mug-top brewing.
Mistakes to Avoid with Reusable Pour-Over Coffee Filter Cone
- Grinding too fine for a metal filter — espresso-fine grounds pass the mesh and leave silt in the cup.
- Choosing a single-layer cone for a 74 µm cup; only the double-layer construction reaches that clarity without collapsing.
