How does an integrated cooking fume purifier work?

It captures fumes through the hood, purifies them through mechanical separation, electrostatic, UV or activated-carbon sections, and then exhausts the treated air; different configurations handle particles and odors differently. Do not judge it by the word integrated alone; confirm which purification stages are actually installed. Checklist: Define capacity, accuracy, materials and operating environment before requesting quotes on a uniform basis. Request specification sheets, test reports, certificates, maintenance manuals and spare-part lists. During acceptance, verify appearance, dimensions, functions, safety protection and packaging, and keep test records. Do not compare unit price alone; include customization, freight, spare parts, after-sales support and downtime risk. Keep written records of inquiries, confirmations, FAT, acceptance and warranty commitments.
