{"product_id":"filterlogic-gravity-water-filter-replacement-for-berkey®-bb9-2®-purewell®","title":"Filterlogic Gravity Water Filter Collection for Compatible BB9-2 and Gravity Systems in Four Styles","description":"\u003cp\u003eA gravity water filter replacement provides carbon filtration for compatible countertop systems without electrical power. The detailed Filterlogic FL-BF90 Count of 2 set uses natural coconut-shell activated carbon to reduce chlorine, heavy metals, sediment, sand, rust, odor, and large particles while improving water taste.\u003c\/p\u003e\u003cp\u003eThe two black cartridges include washers, wing nuts, and a user manual. Their fittings are designed for compatible Berkey BB9-2 and Travel, Big, Royal, Imperial, and Crown gravity systems, with the source also referencing Purewell; confirm the exact system and stem dimensions before ordering. The pair is recommended for replacement after 6,000 gallons, with actual life dependent on source water and use. NSF\/ANSI 42 and 372 certifications support filtration and lead-free material claims, while the filters do not lower TDS. Recorded styles include Count of 2, count 4, Fluoride Water Filter, and Black plus Fluoride Water Filter. Fluoride-stage contents and performance differ from the detailed carbon pair, so select by exact SKU. Before installation, connect each black filter to a compatible faucet and flush it for one minute, then secure the washer and wing nut without overtightening.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: Filterlogic\u003c\/li\u003e\n\u003cli\u003eModel: FL-BF90\u003c\/li\u003e\n\u003cli\u003eProduct: Gravity water filter collection\u003c\/li\u003e\n\u003cli\u003eDetailed style: Count of 2\u003c\/li\u003e\n\u003cli\u003eOther styles: Count 4 Fluoride or Black plus Fluoride\u003c\/li\u003e\n\u003cli\u003eDetailed contents: 2 carbon filters and user manual\u003c\/li\u003e\n\u003cli\u003eMedia: Natural coconut-shell activated carbon\u003c\/li\u003e\n\u003cli\u003eMaterials: Lead-free and BPA-free\u003c\/li\u003e\n\u003cli\u003eCapacity per pair: Up to 6000 gal\u003c\/li\u003e\n\u003cli\u003eReduces: Chlorine heavy metals sediment sand rust odor and large particles\u003c\/li\u003e\n\u003cli\u003eEffect on TDS: Does not lower TDS\u003c\/li\u003e\n\u003cli\u003eCompatibility: BB9-2 and listed Travel Big Royal Imperial and Crown systems\u003c\/li\u003e\n\u003cli\u003eAdditional compatibility reference: Purewell gravity systems\u003c\/li\u003e\n\u003cli\u003eCertification: NSF\/ANSI 42 and 372\u003c\/li\u003e\n\u003cli\u003ePreparation: Faucet flush for 1 minute\u003c\/li\u003e\n\u003cli\u003eMounting: Washer and wing nut\u003c\/li\u003e\n\u003cli\u003eDimensions listed: 2.9 x 5.7 x 10 in\u003c\/li\u003e\n\u003cli\u003eDetailed pair weight: 1.5 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003csection class=\"product-faq\"\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eWhich gravity systems fit the detailed filters?\u003c\/h3\u003e\n\u003cp\u003eThe FL-BF90 pair fits listed BB9-2 and Travel Big Royal Imperial and Crown systems; verify exact stem dimensions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eHow long does the pair last?\u003c\/h3\u003e\n\u003cp\u003eReplacement is recommended after up to 6000 gallons with actual life depending on water quality and use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eDo the filters lower TDS?\u003c\/h3\u003e\n\u003cp\u003eNo. The source explicitly states that these carbon filters do not lower TDS.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eHow are the black filters prepared?\u003c\/h3\u003e\n\u003cp\u003eConnect each to a compatible faucet and flush for one minute before mounting it with the washer and wing nut.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"My Store","offers":[{"title":"Fluoride Water Filter","offer_id":64474722959729,"sku":"B0B4RDCBG7","price":0.0,"currency_code":"USD","in_stock":false},{"title":"Count of 2","offer_id":64474722992497,"sku":"B09KGY9SS8","price":64.98,"currency_code":"USD","in_stock":true},{"title":"Black \u0026 Fluoride Water Filter","offer_id":64474723025265,"sku":"B07YV1HX3Y","price":0.0,"currency_code":"USD","in_stock":false},{"title":"count 4","offer_id":64474723058033,"sku":"B0DQV535LJ","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/7064\/0241\/files\/41Ox2qY8DML._AC_SL1500.jpg?v=1787969418","url":"https:\/\/allkindora.shop\/products\/filterlogic-gravity-water-filter-replacement-for-berkey%c2%ae-bb9-2%c2%ae-purewell%c2%ae","provider":"All Kindora","version":"1.0","type":"link"}
