Which Symphony Diet 3D model is best for a medium-sized room?

For a medium-sized room (around 150–170 sq. ft.), the Symphony Diet 3D 55i+ is one of the best choices. It offers a 55-liter water tank, 3-side honeycomb cooling pads, and a powerful blower that ensures effective cooling across the room. It also features i-Pure technology for cleaner air, a pop-up touchscreen, and a magnetic remote for easy control.

Is the Symphony Diet 3D suitable for use in coastal or humid areas?

Yes, the Symphony Diet 3D air cooler is suitable for coastal or humid areas, but with a few considerations. It uses evaporative cooling, which works best in dry climates. However, models like the Diet 3D 55i+ and 30i are equipped with i-Pure technology—a multi-stage filtration system that helps improve air quality by reducing dust, allergens, and odours. This is especially helpful in humid, coastal environments where air can feel heavy or stale.

What is the average cooling area covered by the Symphony Diet 3D 55i+?

The Symphony Diet 3D 55i+ air cooler is designed to cool rooms up to 16 square meters (approximately 170 square feet)2. This makes it a great fit for medium-sized spaces like bedrooms, study rooms, or small living areas. Its 55-liter tank, 3-side honeycomb pads, and powerful blower ensure consistent airflow and effective cooling throughout the room.

How often should the cooler pads be cleaned or replaced?

To keep your Symphony Diet 3D air cooler running efficiently, it is recommended to:

  • Clean the honeycomb cooling pads once every 2–3 weeks during peak usage months. Simply remove the pads, rinse them with clean water, and let them dry in sunlight before reinstalling. This helps prevent dust buildup and maintains airflow.
  • Replace the pads every 2 summer seasons or sooner if they appear worn out, discoloured, or lose their shape.

Regular maintenance not only improves cooling performance but also extends the life of your cooler.

What variants are available under the Symphony Diet 3D series?

The Symphony Diet 3D series offers a range of tower-style air coolers designed for small to medium spaces with stylish looks and efficient performance. Key models include the Diet 3D 30i and 40i, both featuring i-Pure filtration, touchscreen controls, and magnetic remotes. The Diet 3D 55i+ adds more power and coverage for medium rooms, while the 30B and 55B variants use energy-saving BLDC motors and offer 7-speed fan settings. All models are inverter-compatible, with water tank capacities ranging from 30 to 55 liters, making them ideal for urban homes where space, comfort, and efficiency matter most.
