Air Purification Technology Explained

This air purifier uses a powerful 3-stage air purification system.

• The first stage is a pre-filter that captures large particles like dust, hair, and PM10 particles. This helps protect the inner filters and improves overall efficiency.

• The second stage is Coway’s patented urethane carbon filter. It removes bad odors, cooking smells, smoke, and harmful gases like VOCs and formaldehyde. This is especially useful in Indian kitchens and urban apartments.

• The third stage is the special green anti-virus true HEPA filter. This filter captures PM2.5 particles, allergens, bacteria, and viruses as small as 0.001 microns. It does not just trap pollutants but kills viruses and germs with 99.99 percent efficiency, providing extra protection for families.

Build Quality and Design

This air purifier comes in a clean white finish with a compact and modern design. It blends easily into bedrooms, living rooms, or workspaces. The purifier weighs around 5.5 kg, making it easy to move from one room to another. The build quality feels solid and premium, and the buttons are responsive and easy to use.

Real-Time Air Quality Monitoring

This air purifier has an inbuilt air quality sensor that continuously checks the air in your room. The air quality is shown using a four-color LED indicator. Each color represents a different pollution level, helping users understand when air quality improves or worsens. However, based on user feedback and expert analysis, the sensor can sometimes be slow to detect sudden spikes in pollutants, so you may occasionally need to manually adjust the fan speed.

Smart Auto Mode Performance

The Smart Auto Mode uses a high-precision PM2.5 dust sensor to automatically adjust the fan speed. When pollution levels increase (like during sweeping or cooking), the purifier ramps up immediately. Once the air is clean, it drops back to a lower speed. This 'set it and forget it' functionality makes daily usage effortless and ensures you aren't wasting energy when the air is already pure.

Noise Level and Sleep Comfort

One of the biggest strengths of the Coway Airmega 150 is its silent operation. At its lowest setting, it emits only 22 dB, which is quieter than a whisper or a rustling leaf. Even at its max speed of 49 dB, the sound is a steady white noise rather than a harsh rattle. This makes it a top-tier choice for light sleepers, study rooms, or nurseries where silence is a priority.

Room Coverage and Suitability

This air purifier is suitable for rooms up to 355 square feet. It works well in living rooms, king or queen size bedrooms, kitchens, and home offices. It is designed keeping Indian room sizes and pollution conditions in mind.

Filter Life and Maintenance

Coway offers one of the longest filter lives in this segment. The HEPA filter is 25 mm thick and lasts up to 8,500 hours of usage. This reduces replacement frequency and saves money in the long run. The one-touch cartridge filter system allows easy removal and cleaning without touching dust or getting your hands dirty.

Power Consumption

Airmega 150 uses only 35 watts of power. You can run it for long hours without worrying about high electricity bills. This makes it suitable for daily and overnight use.

Warranty and Service Support

Coway provides 5 years warranty on the motor and 1 year on electrical parts. After registration on the official Coway website, the motor warranty extends to 7 years, providing peace of mind. With over 90 service offices across India, Coway offers free installation and doorstep service.
