How should electrostatic, UV and composite integrated purifiers be chosen?

Electrostatic units mainly remove fume particles, UV helps break down odors and organic matter, and composite units combine mechanical separation, electrostatic treatment, UV or carbon when both smoke and odor control are needed. Electrostatic treatment may suffice for visible smoke, while barbecue, stir-frying and strong-odor kitchens usually need a composite configuration. 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.
