{"product_id":"sibarist-flat-2-m-filters-flat-bottom-brewers","title":"Sibarist FLAT 2 M Paper Filters for Flat Bottom Brewers","description":"\u003cp class=\"product-lead\"\u003eThe Sibarist FLAT 2 M is a specialty paper filter designed for 02-size (medium, 1–4 cup) flat bottom brewers, built around a zero-bypass brewing principle. The filter adheres fully to the dripper walls, eliminating air channels and preventing coffee particles from becoming trapped in fluted or wavy surfaces. Sold in packs of 100 sheets, the FLAT 2 M suits baristas, competition brewers, and home enthusiasts who want consistent, repeatable extractions.\u003c\/p\u003e\n\n\u003ch2\u003eZero-Bypass Design for Controlled Extraction\u003c\/h2\u003e\n\u003cp\u003eThe Sibarist FLAT 2 M adheres completely to the walls of a flat bottom dripper, sealing off the air channels that can form between a conventional filter and the dripper's interior. When bypass is removed from the equation, water travels through the coffee bed rather than around it, which means every gram of coffee contributes to the extraction. The result is a more even, repeatable brew from one cup to the next, a meaningful advantage for anyone dialing in a recipe or brewing for competition.\u003c\/p\u003e\n\n\u003ch2\u003eFAST Technology: Even Flow Without Air Channels\u003c\/h2\u003e\n\u003cp\u003eThe FLAT 2 M is built on Sibarist's FAST Specialty Coffee Filter technology, a paper construction that achieves a fast, even drawdown without relying on air channels to regulate flow. Brewers can experiment with grind size, pulse rates, and agitation to tune extraction speed rather than being constrained by the filter's physical structure. The seamless plug-and-play fit into compatible flat bottom brewers also reduces setup variables, keeping workflow consistent across brew sessions.\u003c\/p\u003e\n\n\u003ch2\u003eMaterials and Sourcing\u003c\/h2\u003e\n\u003cp\u003eSibarist FLAT 2 M filters are made from a blend of abaca fiber, cellulose fiber from European pine plantations, and organic plant-based polylactic acid. Abaca fiber is finer and more porous than standard wood-based fibers, contributing to the filter's permeability and wet-strength without adding excess paper mass. The filters are 100% organic and crafted in Barcelona. Packaging is sealed to protect against dust and odors, and the paper packaging itself carries FSC certification.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eZero-bypass flat-bed structure:\u003c\/strong\u003e filter adheres fully to dripper walls, eliminating air channels and bypass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFAST Specialty Coffee Filter technology:\u003c\/strong\u003e even, fast drawdown without reliance on air channels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbaca-fiber construction:\u003c\/strong\u003e fine, porous, high wet-strength fiber blend for clean cup character\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% organic, made in Barcelona:\u003c\/strong\u003e plant-based polylactic acid binder, FSC-certified paper packaging\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSealed packaging:\u003c\/strong\u003e protects sheets from dust and odors between uses\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFilter shape\u003c\/td\u003e\n      \u003ctd\u003eFlat bottom\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSize\u003c\/td\u003e\n      \u003ctd\u003eFLAT 2 M: fits 02 \/ medium flat bottom brewers (1–4 cup)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSheets per pack\u003c\/td\u003e\n      \u003ctd\u003e100\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFilter technology\u003c\/td\u003e\n      \u003ctd\u003eFAST Specialty Coffee Filter\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePrimary fiber\u003c\/td\u003e\n      \u003ctd\u003eAbaca (banana plant fiber)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAdditional materials\u003c\/td\u003e\n      \u003ctd\u003eFSC\/PEFC cellulose from European pine; organic plant-based polylactic acid\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOrigin\u003c\/td\u003e\n      \u003ctd\u003eBarcelona, Spain\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCertification\u003c\/td\u003e\n      \u003ctd\u003e100% organic; FSC-certified packaging\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePackaging\u003c\/td\u003e\n      \u003ctd\u003eSealed, FSC-certified paper packaging\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThe Sibarist FLAT 2 M suits baristas, competition brewers, and home enthusiasts using 02-size (medium) flat bottom drippers who want to minimize bypass and maximize extraction consistency. The fast-flow design rewards brewers who want to actively control variables like grind size, pulse rate, and agitation rather than relying on a slow, restrictive filter.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThe FLAT 2 M is not compatible with cone-shaped or wave-style drippers. It is designed specifically for flat bottom brewers in the 02 \/ medium size. Brewers seeking a slower, more restrictive drawdown or using a different dripper size will need a different filter.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhich drippers are compatible with the Sibarist FLAT 2 M?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Sibarist FLAT 2 M is sized for 02 \/ medium flat bottom brewers designed for 1–4 cups. It is not intended for cone or wave drippers. Confirm your dripper's base shape and size before ordering, as the zero-bypass design depends on a precise fit against the dripper walls.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat does \"zero-bypass\" mean in practice?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eIn a zero-bypass setup, the Sibarist FLAT 2 M filter adheres fully to the interior walls of the dripper, sealing off the gap that can form between a conventional filter and a fluted or wavy surface. Water is directed through the coffee bed rather than around it, which promotes more even extraction and reduces the chance of under-extracted channels forming during the brew.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eHow does FAST technology affect flow rate?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eSibarist's FAST Specialty Coffee Filter technology relies on abaca fiber, a finer and more porous material than standard wood pulp, to achieve a fast, even drawdown without relying on physical air channels. Brewers can tune extraction speed by adjusting grind size, pulse rate, and agitation rather than being limited by the filter's inherent resistance.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eAre the Sibarist FLAT 2 M filters organic and sustainably sourced?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. Sibarist FLAT 2 M filters are 100% organic and made in Barcelona from abaca fiber, FSC\/PEFC-certified cellulose from European pine plantations, and an organic plant-based polylactic acid binder. The paper packaging is FSC-certified. Abaca is harvested from replanted plantations in Ecuador and the Philippines under a chain-of-custody process.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eHow should the filters be stored between uses?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eSibarist FLAT 2 M filters ship in sealed packaging specifically designed to protect the sheets from dust and odors. Keeping the pack sealed between brew sessions helps preserve the filter paper's neutral character and prevents contamination that could affect cup flavor.\u003c\/p\u003e","brand":"Sibarist","offers":[{"title":"100 Sheets","offer_id":68211108249821,"sku":"SPS-SI\/FL2\/100","price":54.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0614\/3315\/1709\/files\/SIBARIST_FLAT_2_M-3-sq.jpg?v=1792208351","url":"https:\/\/coffeeroastco.com\/es\/products\/sibarist-flat-2-m-filters-flat-bottom-brewers","provider":"CoffeeRoast Co.","version":"1.0","type":"link"}
