Fungus growth: If the smell is coming from a dark, lighted area, it may be due to fungus growth.
Bacteria: Bacterial growth on surfaces can also cause odors.
Toxic Substances in the Environment: Chemicals and chemical reactions can cause odors.

– Finding the cause and eliminating it or containing it to stop odor production are the best ways to manage indoor odors.

-By opening windows and turning on fans, proper air conditioning helps improve fresh air ventilation, which helps reduce odors until the source is eliminated.

-To avoid inhaling harmful substances in public places, it is advisable to use a mask when going out.

However, using scented candles and room fresheners to remove bad odors may not be the best idea.

By releasing more chemicals into the indoor air, these fragrances simply mask or mask other scents. They can irritate sensitive people or trigger allergic reactions.”
