But real performance depends on the filtration technology.<\/p>\n<p data-start=\"989\" data-end=\"1079\">The key is understanding that not all recirculation systems remove odours in the same way.<\/p>\n<p data-start=\"1081\" data-end=\"1162\">Many hoods include standard carbon filters. They work, but they have limitations:<\/p>\n<ul data-start=\"1163\" data-end=\"1257\">\n<li data-start=\"1163\" data-end=\"1187\">\n<p data-start=\"1165\" data-end=\"1187\">They saturate faster<\/p>\n<\/li>\n<li data-start=\"1207\" data-end=\"1257\">\n<p data-start=\"1209\" data-end=\"1257\">They may be insufficient in open-plan kitchens<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"1259\" data-end=\"1411\">That\u2019s why advanced systems exist, solutions that don\u2019t rely on a single filter but on different technologies depending on usage and performance needs.<\/p>\n<h3 data-start=\"1418\" data-end=\"1457\">Systems that truly make a difference<\/h3>\n<h4 data-start=\"1459\" data-end=\"1472\">1. Plasma<\/h4>\n<p data-start=\"1473\" data-end=\"1528\">For those who cook frequently and want maximum control.<\/p>\n<p data-start=\"1530\" data-end=\"1584\">The most advanced air purification solution, ideal if:<\/p>\n<ul data-start=\"1585\" data-end=\"1698\">\n<li data-start=\"1585\" data-end=\"1603\">\n<p data-start=\"1587\" data-end=\"1603\">You cook daily<\/p>\n<\/li>\n<li data-start=\"1604\" data-end=\"1664\">\n<p data-start=\"1606\" data-end=\"1664\">You prepare dishes with strong odours, grease or vapours<\/p>\n<\/li>\n<li data-start=\"1665\" data-end=\"1698\">\n<p data-start=\"1667\" data-end=\"1698\">You have an open-plan kitchen<\/p>\n<\/li>\n<\/ul>\n<h4 data-start=\"1700\" data-end=\"1722\">2.

Installation requires no tools.<\/p>\n<h4 data-start=\"1840\" data-end=\"1868\">3. FC-Plus active carbon<\/h4>\n<p data-start=\"1869\" data-end=\"1941\">A high-performance, balanced option for homes where cooking is frequent.<\/p>\n<p data-start=\"1943\" data-end=\"2067\">It absorbs odours better than standard carbon and offers longer durability. It is also biodegradable and generates no waste.<\/p>\n<h4 data-start=\"2069\" data-end=\"2089\">4.
