International Indoor Air Purification 2027

About the fair

The Expo for International Indoor Air Purification (CIEQ) is an international Chinese exhibition of solutions, products and services for improving quality of life inside residential, office, retail, medical, educational, industrial and other commercial and industrial spaces. It focuses on modern technical means and professional solutions for high-quality indoor living, with an emphasis on the most effective way to improve indoor spaces — air purification. Visitors see air-pollution monitoring and control systems, air purifiers, ventilation, dust-protection, photocatalysis, disinfection and antibacterial systems, air testing and lab analysis, green finishing building materials and other clean-environment solutions for buildings.

Planning the trip

• Register the badge online. Every major fair issues visitor badges in advance, and on-site registration means queueing on the busiest morning of the show. Registration usually opens one to two months out.
• Check the visa position early. China's entry rules have changed repeatedly in recent years, including visa-free arrangements for a growing list of countries and transit exemptions. Confirm what applies to your passport for this month, and ask the organiser for an invitation letter if a business visa is needed — issuing one is routine.
• Book accommodation before the dates firm up. A large fair fills its host city and rates move accordingly. Cancellable bookings made early cost less than confirmed ones made late.
• Decide which halls before you arrive. The bigger Chinese fairs run to several halls across separate phases, and walking them without a plan burns a day. Shortlist the stands you need and treat anything else as a bonus.
• Plan the follow-up, not just the visit. Business cards collected at a fair convert poorly once you fly home: quotes arrive in patchy English, samples stall, and the time difference eats a day per exchange. Deciding who handles that before you travel is what makes the trip pay for itself.
