Many common items may cause bad indoor air quality in your London house.
- Substances in carpeting, furniture and drapes that let off fumes
- Cleaning supplies
- Personal care products
- Air fresheners and candles
Though they are often more efficient, modern homes don’t have fresh air the way older houses do. Tight weather stripping and storm doors keep interior air in and outdoor air out. This offers more energy savings, but the lowered exchange of outdoor and indoor air can trigger contaminants building up inside.
When this happens, a whole-house ventilation system is recommended. Ventilation systems swap out dirty inside air for cleaner exterior air without giving up energy savings.
