What does a cooking fume purifier do?

A cooking fume purifier captures and removes oil droplets, particles and some organic pollutants from cooking emissions, but it does not replace the hood or fan. A complete exhaust system usually includes the hood, ducting, purifier, fan and discharge point. 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.
