Air Purification Technology Explained

The Air Purifier uses a HEPA filtration system capable of trapping extremely fine particles.

• Removes PM2.5 particles, dust, smoke, and pollen
• Helps reduce allergens and airborne irritants
• Improves indoor air quality in polluted environments

This makes it suitable for allergy sufferers and homes located in high-pollution areas.

Smart App and Voice Control Experience

One of the strongest features of the Qubo Smart Air Purifier is its app-based control. The Qubo app allows you to turn the purifier on or off remotely, monitor indoor air quality, change fan speed, set schedules, and track filter life.

Amazon Alexa support enables voice control for hands-free operation. Once configured, basic commands work smoothly.

Noise Level and Daily Comfort

Noise levels remain comfortable on low and medium settings, making the purifier suitable for bedrooms and night-time use. It does not disturb sleep or work-from-home routines.

Room Coverage and Suitability

This air purifier is designed for medium rooms up to 400 square feet. It performs well in living rooms, bedrooms, and home offices.

Filter Life and Maintenance

Filter replacement depends on usage and air quality conditions. In most homes, the HEPA filter typically needs replacement every 6 to 12 months. Regular maintenance helps maintain consistent purification performance.

Power Consumption and Efficiency

The purifier is energy-efficient and suitable for long daily usage. Continuous operation does not significantly increase electricity bills, making it practical for Indian households.
