Aluminum strips themselves do not directly affect indoor air quality. They are often used in construction and design for their strength and lightweight properties. However, if aluminum strips are improperly treated or coated with harmful chemicals, they could potentially off-gas and contribute to poor indoor air quality. Additionally, aluminum strips can sometimes be used in conjunction with air purifiers or ventilation systems, where they might help in filtering out pollutants. It's essential to ensure that any materials used in indoor spaces are safe and do not release harmful substances into the air.
