The Khan family had been struggling with persistent health issues – their two children experienced frequent allergy symptoms and asthma attacks, particularly during Dhaka’s high-pollution seasons. Despite regular cleaning, they noticed:
Constant dust accumulation on surfaces
Musty odors in certain rooms
Worsening allergy symptoms indoors versus outdoors
Poor sleep quality due to breathing difficulties
Medical advice pointed to poor indoor air quality as a significant contributing factor to their health concerns.
