{"product_id":"berkey-pf-2-fluoride-arsenic-replacement-filters-2-pack-megean","title":"2-Pack Replacement Filters X61601","description":"Keep clean water flowing with these Berkey PF-2 Fluoride\/Arsenic Replacement Filters. Each pack comes with two filters so you can keep a fresh one handy. The fluoride water filters remove fluoride, arsenic V, pre-oxidized Arsenic III and other residual heavy metal ions. It's recommended that each set of two PF-2 elements be replaced after 1,000 gallons. As an example, The Royal Berkey system is about 3.25 gallons and therefore the filters should be replaced after 307 (1,000\/3.25) refills. Or in other words, if the system is refilled about one time per day they, should be replaced after 10 months; if the system is refilled about twice per day, they should be replaced about every 5 months. The arsenic water filters are easy to install because you simply screw the PF-2 fluoride filter into the Black Berkey filters.","brand":"My Store","offers":[{"title":"Default Title","offer_id":43624711913533,"sku":"P357680392372886479","price":11.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/5987\/5901\/files\/d87d4e3dcfb51379d99fd91b225d01066d3a0c3c11740150607b6b0e02ad7dde.jpg?v=1789457906","url":"https:\/\/twhgj.shop\/products\/berkey-pf-2-fluoride-arsenic-replacement-filters-2-pack-megean","provider":"My Store","version":"1.0","type":"link"}
