Ideally, the humidity level in your home should be between 40% and 60%. The cheapest and easiest way to keep humidity at this optimal level is to open your curtains and windows. It’s amazing the difference that sunlight and fresh air can make to your home
– and it’s free!
- Be sure your home has enough ventilation.
a) Leave windows and doors open as much as possible.
b) Use exhaust fans which vent outside your home in the kitchen and bathroom.
- Increase circulation throughout the home by using fans and opening closet doors and drawers as often as possible.
- Ensure that kitchen exhaust fans are vented to the outside and used regularly when cooking. Cover boiling pots to prevent moisture build-up.
- Discard clutter – especially in storage areas. Moulds grow on paper, fabrics, wood and anything else that holds moisture and collects dust. If you must store items like paper, clothes and fabric, do so in sealed containers.
- Ask family and friends to remove shoes when entering your home. Mould spores from soil, dust and air can attached to shoes.
- Consider not using carpet in rooms or areas like bathrooms or basements that commonly contain a lot of moisture.
- Check for water leaks under the sink, around the tub, shower and toilet to prevent water damage and mould.
- Leave the exhaust fan on for several minutes after showering is completed. Take shorter showers. Wiping down wet surfaces after showering is also beneficial.
- Make sure your clothes dryer vents to the outside of your home. Better still - use your dehumidifier. Clothes will dry gently and naturally.
- Immediately repair any leaks in the roof, walls or plumbing so mould does not have moisture to feed on.
- Be mindful of humidity levels. Moulds thrive in warm, humid conditions. A dehumidifier separates moisture from the air, thereby changing the conditions to dry and fresh.
- You can monitor the moisture content in your building with a hygrometer. Relative humidity in the home should be under 45 percent in the winter (or lower to avoid condensation on windows). A dehumidifier will help lower the relative humidity dramatically.
- If you have heat recovery ventilators (HRV) clean the filter inside often.
- Frequently cleaning the drip pan at the back of the refrigerator and vacuum dust from refrigerator coils.
- Take out rubbish daily and clean garbage cans frequently.
- Don’t bring into the home furniture, clothing, books or other items that have been water damaged or stored in a damp or mouldy place.
- Use a vacuum cleaner with a HEPA Filter.
- Check outside of the home also on a regular basis for places where water may intrude or pool.
a) Check eaves, gutters and downpipes regularly to make sure they are connected, working properly and debris-free.
b) Install downpipe extensions to lead water further away from the home.
- Choose central air conditioning with a HEPA filter attachment is best.
Special attention is required to drying after flooding. Clean up and dry out your home thoroughly and quickly within 24 hours of flooding.
