This project introduces a low-cost, energy-efficient DIY air cooler combined with an aroma diffuser, ideal for hot regions with limited electricity. Made from accessible materials—plastic containers, Peltier modules, heat sinks, fans, mist makers, and essential oils—it offers cooling and air freshness. The system uses evaporative cooling, a Peltier module, and a mist maker for enhanced performance. Testing showed a 23% reduction in ambient temperature using the cooler alone, increasing to 33% with ice cube integration.  Costing only RM150–RM200, it's easy to assemble and eco-friendly. Suitable for low-income users, students, and off-grid areas, it also has strong potential as a DIY kit, wellness product, and educational tool.
