Before you start cleaning, you should first try to resolve this by priming the Black Berkey filter elements again. You shouldn\u2019t clean them too often; when using tap water, once every six months is sufficient. If priming does not improve the filtration rate, then it is time to clean the filters. However, you must prime them again after cleaning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Priming ensures that the air is expelled from the filters, which then allows them to flow through more quickly again. After a while\u2019s use, the air gradually builds up in the filters again. You can do this by <a href=\"\/en\/products\/priming-button-for-black-berkey-elements\/\">Priming Button<\/a>, the <a href=\"\/en\/products\/black-berkey-primer\/\">Black Berkey Primer<\/a> or the <a href=\"\/en\/products\/berkey-water-filters-priming-starter-kit\/\">Blue Primer Rite<\/a> use. See also the <a href=\"\/en\/instructional-videos-on-berkey-water-filters\/\">instructional videos<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you do need to clean the filters, please refer to the instructions under the heading \u201cCleaning, maintenance and storage\u201d.<\/p>","protected":false},"featured_media":0,"parent":0,"menu_order":0,"template":"","faq-categorieen":[1095,1096],"class_list":["post-26712","ufaq","type-ufaq","status-publish","hentry","faq-categorieen-berkey","faq-categorieen-gebruik"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>De filtersnelheid van de Black Berkey filters is merkbaar afgenomen.
