Street food and night market vendors operate in the most challenging air quality environment of all: no permanent infrastructure, variable stall locations, exposure to weather, and close customer proximity. The Souniny LD and Prince Series provide professional-grade purification in packages small and robust enough for street-level deployment.

Application Scenarios
- Taipei Shilin Night Market (Taiwan): Multiple food stalls at Taipei’s largest night market use Prince ESP-2000 units mounted on custom brackets above wok and fryer stations. The market operates in a partially covered pedestrian street where smoke was previously a major pedestrian experience issue. Stall owners report that neighboring clothing and accessory vendors — who had complained for years about grease contamination on merchandise — have stopped complaining since the purifiers were deployed.
- Chatuchak Weekend Market (Bangkok): Hot food vendors at Chatuchak, one of the world’s largest weekend markets, use Light-duty Series units mounted on lightweight aluminum frames. The frames are designed to be assembled and disassembled within 15 minutes — critical for vendors who only operate Saturday-Sunday. The system runs on the market’s provided electrical supply.
- Hawker center modernization (Singapore): Singapore’s National Environment Agency (NEA) has been upgrading hawker centers with centralized exhaust systems. For centers where structural limitations prevent duct installation, Light-duty Series units have been deployed as an approved alternative. One hawker center in Toa Payoh with 30 stalls used distributed LD units, with positive feedback from stall owners about reduced cleaning requirements.
- Christmas market food stalls (Germany): A chain of Christmas market food vendors operating at 6 different German cities during the winter season uses Prince ESP-2000 units at bratwurst and potato pancake stalls. The units run on the market’s temporary power supply. The vendor company’s owner reports that event organizers now specifically request stalls with visible purification equipment, as it demonstrates compliance with increasingly strict event air quality requirements.
- Mobile food truck rally (USA): A food truck that participates in weekend rallies and festivals across Texas installed a Light-duty Series in a custom rooftop enclosure. The 12V DC fan option runs off the truck’s auxiliary battery during transit setup, switching to mains power once connected at the event site. The truck is regularly positioned adjacent to a craft beer tent — the event organizer initially separated the truck due to smoke concerns, but now places them together without issues.
