When temperatures rise and the heat becomes unbearable, choosing the right air cooler can be the difference between discomfort and relief. But with so many types—desert, room, and personal air coolers—how do you make the right call for your space, climate, and usage needs?
This detailed guide will help you understand the differences between each type of air cooler, including real-world use cases, comparison tables, and FAQs to help you pick the perfect match from Symphony’s wide product range.
Understanding the Types of Air Coolers
Air coolers are categorized primarily by their cooling capacity, tank size, and ideal room size. Let’s break down the three main types.
Desert Air Coolers
Desert coolers are built for large spaces and peak summer conditions. These high-capacity models come with large tanks (70L–200L), wide air throw, and powerful fan systems—ideal for long-duration use and open spaces.
Use if you need to:
- Cool living rooms, large halls, offices, or semi-open areas
- Operate the cooler for hours without frequent refilling
- Achieve intense cooling in dry, arid climates
Popular Symphony models:
- Silenzo 120i (120L, 34m²)
- Maxwind 120EX (120L, 48m²)
- Jumbo 200EX (200L, 48m²)
- Storm C 100XL (95L, 45m²)
Room Air Coolers
Room air coolers strike a balance between cooling capacity and size. They work best in medium-sized bedrooms, guest rooms, and lounges, offering decent air throw and moderate tank capacity.
Use if you need to:
- Cool areas between 16m² and 30m²
- Keep the noise level low while you sleep or work
- Fit the cooler into indoor spaces without cluttering
Popular Symphony models:
- Touch 55 (55L, 30m²)
- HiCool 45i (45L, 17m²)

Personal Air Coolers
Personal coolers are designed for targeted cooling in small areas. They are lightweight, energy-efficient, and ideal for single-user rooms such as study corners or compact bedrooms.
Use if you need to:
- Cool personal areas under 14m²
- Move the cooler easily between rooms
- Focus on budget-friendly, low-noise performance
Popular Symphony models:
- Diet 8i (8L, 10m²)
- Ice Cube 17i (17L, 16m²)
- Diet 3D 12i (12L, 12m²)
How to Choose the Right Type for Your Room Size?
Start by measuring your room in square meters (length × width). Based on that, choose the cooler with adequate coverage and tank capacity.
| Room Size | Recommended Cooler Type | Tank Capacity | Suggested Models |
| Up to 14m² | Personal Cooler | 8–22L | Diet 8i, Ice Cube 17i, Diet 12i |
| 15–30m² | Room Cooler | 30–60L | Touch 55, HiCool 45i, Touch 35 |
| 30m² & Above | Desert Cooler | 70–200L | Sumo 115 XL, Storm 70 XL, Jumbo 200EX |
Tip: For hot regions or sunlit rooms, consider upsizing your cooler for better performance.
