Why Air-Purifying Plants Matter in Dhaka

Dhaka is one of the most densely populated cities in the world — and with density comes air quality challenges. According to IQAir, Dhaka consistently ranks among the cities with the highest PM2.5 levels globally. While we can't control outdoor air pollution, we can dramatically improve the air inside our homes.

Indoor air can be 2 to 5 times more polluted than outdoor air, thanks to traffic fumes seeping in from windows, furniture off-gassing (formaldehyde from plywood, MDF, and upholstery), cleaning products releasing VOCs, and printers/electronics releasing ozone and particulate matter.

Enter: indoor plants.

NASA's famous Clean Air Study (1989) found that certain houseplants can remove up to 87% of indoor air pollutants within 24 hours. Plants act as natural air filters — absorbing toxins through their leaves and roots, converting CO₂ to oxygen, and releasing moisture into the air.

For Bangladeshi homes, the benefits are multiplied:

- Reduced respiratory issues — cleaner air means fewer allergies and asthma triggers

- Better sleep — plants like Snake Plant release oxygen at night

- Improved focus — greenery reduces stress and boosts productivity by 15%

- Natural humidifiers — combat the dry air from AC units
