Question

How can you improve indoor air quality?

Answer 1

Air quality is important to both human health and overall environmental quality.

Indoor air quality can be improved by increasing ventilation in enclosed spaces. Correct answer: D

Some other methods include: keeping the house clean, invest in an air purifier, change the filters of the forced-air heating system regularly etc.

Answer 2

Hey there!

Increasing ventilation in enclosed spaces would for sure improve indoor air quality.

Keeping pets indoors, using darker paint on all interior walls installing sunscreens in all windows would not help improve indoor air quality.

I hope this helped! :-)
