Ventilating Against Aerosols
In small, poorly ventilated rooms, aerosols—tiny droplets with viruses—can remain in the air for longer periods, as research shows. Ventilating helps dilute the air and remove pollutants more easily, reducing the concentration of aerosols and lowering the risk of contamination.
Tips for Ventilating with Minimal Heat Loss
Even in old homes with gaps and cracks, natural ventilation isn’t always enough. In modern, well-insulated homes, ventilation is a key concern. Here are some tips for maintaining healthy air with minimal heat loss:
Keep ventilation vents open for consistent airflow.
If you have small windows (or vents), crack them open when you’re home.
Clean vents at least once a year with a brush or vacuum cleaner. Sometimes the cover can be removed and cleaned with soapy water.
Ensure air can flow through your home. Doors should have at least a 1.5 cm gap under them. If doors are too long, trim them or add vents.
Ensure extra ventilation in the kitchen and bathroom. Use the exhaust fan when cooking and an inbuilt fan in the bathroom during and after showering.
