Our mission

Why is indoor air quality important?

Most people spend around 90% of their time indoors, mainly at home or in the workplace.

Viruses that transmit as airborne particles, such as the viruses that cause COVID-19 and measles, pose a significant risk. They can squeeze into small places nearly 10,000 times smaller than a human hair, travel long distances. and stay active in the air for at least 4 hours.

Ventilation helps clean the indoor air, and it’s essential for reducing the risk of the spread of infectious diseases.

Benefits of proper
ventilation in a building

Oxygen

Oxygen

Provides oxygen and fresh air for human respiration.

dilution

Dilution

Dilutes indoor air pollutants to levels below those recognized to cause disease or injury from exposure to harmful contaminants, odors, and vapors.

aerosol

Aerosol control

Uses outdoor, filtered air with a low aerosol concentration to control aerosols inside buildings.

ventilation

Air distribution

Creates proper air distribution and promotes a healthier and more comfortable environment.
