Central Air Cooling vs Split AC: Choosing the Right System for Large Buildings in India

If you are planning the cooling system for a large building in India, whether it is a school, factory, shopping mall, or office complex, the choice between central air cooling and Split AC is a significant one. Both systems aim to keep indoor spaces comfortable, but they differ in terms of performance, cost, and suitability for Indian climates.

Let’s break it down so you can make a smart, informed decision.

1. Coverage Area

Central Air Cooling is built for scale. It is ideal for large, open layouts like manufacturing units, auditoriums, educational campuses, and multi-storey buildings. One system can cool thousands of square feet.

Split ACs are better suited for smaller, enclosed spaces, such as cabins, classrooms, or individual offices. For a large building, you need dozens of units. In open-plan buildings, Central Air Cooling is the clear winner. For segmented layouts, Split ACs might be more practical.

2. Energy Efficiency & Running Costs

Central Air Cooling uses evaporative cooling, a technology that consumes up to 80% less electricity than conventional ACs. It is especially effective in hot and dry regions like Madhya Pradesh, Rajasthan, and parts of Delhi NCR.

Split ACs rely on compressor-based refrigeration, which is power-intensive. The more units you install, the higher your electricity bills. If you are looking to cut long-term energy costs, Central Air Cooling is far more economical.

3. Installation & Infrastructure

Central Air Cooling requires ducting, a water supply, and planning during construction or major renovation. Once installed, it integrates neatly into the building’s design.

Split ACs are easier to install individually. But in large buildings, installing 20–50+ units can clutter walls and exteriors with outdoor units not ideal for aesthetics or maintenance.

4. Air Quality & Comfort

Central Air Cooling continuously brings in fresh, filtered, and humidified air, great for maintaining healthy indoor environments, especially in dusty or dry regions.

Split ACs recirculate the same indoor air. Over time, this can lead to dryness and stale air, which is not ideal for comfort or health. For better air quality and comfort, Central Air Cooling takes the lead.

5. Maintenance

Central Air Cooling offers centralized maintenance, duct cleaning, water checks, and periodic servicing.

Split ACs require individual upkeep. Each unit needs filter cleaning, coil checks, and gas refills. In large buildings, this becomes a costly and time-consuming task.

6. Cost Consideration

Central Air Cooling involves a higher upfront investment, but its low electricity consumption and centralized maintenance make it cost-effective over time.

Split ACs may seem cheaper initially, but when scaled up, the combined cost of multiple units and high energy use adds up quickly.

7. Climate Suitability

Central Air Cooling works best in hot and dry climates, perfect for much of central and northern India.

Split ACs perform well in all climates, including humid coastal areas like Mumbai, Chennai, and Kolkata.

With rising air pollution in Indian cities, HEPA filters are now more important than ever. From Delhi’s smog to Mumbai’s humidity, air pollution is a common concern across India. With rising air pollution in Indian cities, HEPA filters are now more important than ever. From Delhi’s smog to Mumbai’s humidity, air pollution is a common concern across India.

In fact, Delhi’s air quality has become such a concern that authorities have even explored cloud seeding a weather modification technique that induces artificial rainfall, as a temporary measure to reduce smog. While such outdoor solutions may provide short-term relief, maintaining clean indoor air remains crucial. That’s where HEPA filters come in, especially when used in air purifiers designed for Indian homes. Studies show that indoor air may contain as many, or even more, pollutants than outdoor environments. That’s where HEPA filters come in, especially when used in air purifiers designed for Indian homes.

In this blog, we will explain:

• What HEPA filters are
• How they work
• Why are they essential in air purifiers for the Indian climate and environment

What is a HEPA Filter?

HEPA stands for High-Efficiency Particulate Air filter. A true HEPA filter is certified to remove at least 99.97% of airborne particles that are 0.3 microns in size, including pollutants much smaller than dust.

HEPA filters are used in Home air purifiers, Hospitals, and labs (Medical Grade Air Purifier), HVAC systems, Cars, airplanes, and public transport.

Be cautious of misleading labels. Terms like “HEPA-type” or “HEPA-like” may sound convincing, but they do not meet the official HEPA standards. These filters are often far less effective at capturing fine particles and may compromise air quality. Always look for certified true HEPA filters that comply with standards like EN1822 for guaranteed performance.

How Do HEPA Filters Work?

Unlike simple mesh filters, HEPA filters are made of a dense web of synthetic or glass fibers. As air passes through, particles are trapped by one of three key mechanisms:

1. Impaction: Large particles collide with the fibers and get stuck.
2. Interception: Medium-sized particles follow the airflow but brush against fibers and get caught.
3. Diffusion: Tiny particles like viruses move randomly (Brownian motion) and end up sticking to fibers.

This makes HEPA filters effective at capturing PM2.5 and even smaller particles — a major issue in Indian metros.

In cities like Delhi, Patna, or Kanpur, where AQI often crosses 300+, HEPA filters are crucial for indoor air safety. Check your City Air Quality Here

What Do HEPA Filters Remove?

HEPA filters are effective against:

• Dust and pollen
• Pet dander
• Mold spores
• Smoke and fine particles (PM2.5)
• Bacteria and some viruses

This makes them ideal for people suffering from allergies, asthma, or respiratory issues.

HEPA Filters in Air Purifiers

Most air purifiers in India from brands like Greencon, Coway, Philips, and Dyson use multi-stage purification systems that include:

1. Pre-filter – Traps large particles like hair and visible dust
2. HEPA filter – Captures fine particles like allergens, bacteria, and PM2.5
3. Activated carbon filter – Absorbs gases, VOCs, and odours

Look for “True HEPA” when buying an air purifier — it ensures tested and certified efficiency.

Greencon offers three high-performance HEPairé air purifiers to suit different space sizes and applications—from residential bedrooms to ICUs and operating theatres. All models are equipped with H14 HEPA filters, G4 pre-filters, and select models feature UVGI sterilization.

Benefits of Using HEPA Filters

1. Better Respiratory Health: Helps alleviate breathing problems in children, the elderly, and individuals with asthma.
2. Allergy Relief: Reduces triggers like dust mites, pollen, and pet fur.
3. Cleaner Indoor Spaces: Less dust accumulation on furniture and floors.
4. Post-COVID Safety: Adds an extra layer of protection against airborne viruses and bacteria.

Limitations and Maintenance

1. Cannot remove gases or smells: You’ll need a carbon filter for that.
2. Requires regular replacement: Replace every 6–12 months, depending on usage.
3. Wrong usage reduces efficiency: Place your purifier correctly and ensure it’s suitable for your room size.

In India, where outdoor air pollution is a daily concern, investing in an air purifier with a True HEPA filter is a smart and health-conscious decision. It not only improves air quality but also enhances comfort and well-being inside your home or office.
