Every day, we spend the majority of our time indoors at home and in other buildings for work, study, leisure and rest. Indoor air quality plays a significant part in our general state of health, especially for children, elderly people and other vulnerable groups. Now donning an industrial-grade face mask on the streets might make you feel safer, but did you know that the air we breathe every day at home, school or the office can be just as unhealthy? So how can we protect our health and prevent the air in our homes from becoming a deadly cocktail of airborne pollutants? Why we need proper indoor air quality solutions in our modern lives and how they protect our whole family.

To overcome Thailand’s ventilation challenges, Delta has developed the Energy Recovery Ventilation (ERV) air exchange solution that quietly and efficiently supplies and circulates cooled and purified oxygen-rich air from outside while removing hot indoor air laden with CO2, viruses and pollutants.
