Maintain relative humidity between 30-50% to prevent mould and mildew
Maintaining relative humidity between 30% and 50% is an effective way to prevent mould and mildew, which are common biological pollutants. Biological pollutants are contaminants sourced from living organisms, such as mould, mildew, bacteria, viruses, animal dander, and pollen. These pollutants can cause allergic reactions, trigger asthma, and spread infectious diseases.
Relative humidity refers to the amount of humidity or water vapour in the air compared to the maximum amount the air can hold at that temperature. Warm air can hold more water vapour than cold air. Morning condensation on windows or a musty odour may indicate high humidity in your home.
To maintain relative humidity within the desired range, proper ventilation is essential. Open windows can help reduce humidity, but if the humidity is higher outside, avoid opening windows as this will increase indoor humidity. Heat recovery ventilation systems, exhaust fans in bathrooms and kitchens, and clothes dryers vented to the outside are all effective ways to improve air circulation and reduce moisture.
Additionally, certain appliances, such as humidifiers, kerosene heaters, and gas stoves, can add moisture to the air. If you notice moisture on windows or other surfaces, turn off these appliances. Dehumidifiers and air conditioners are useful for reducing moisture in the air, especially in hot and humid climates. However, ensure that these appliances themselves do not become sources of biological pollutants by regularly cleaning and maintaining them.
By controlling relative humidity and addressing sources of moisture, you can effectively prevent the growth of mould and mildew, creating a healthier and more comfortable indoor environment.

Fix leaks and seepage to avoid water damage
Water leaks and seepage can create conditions for biological pollutants to grow, so it is important to fix these issues to avoid water damage and the negative health effects associated with biological pollutants.
Water seepage is the slow infiltration of moisture through walls, floors, or ceilings, and it often occurs without visible signs. It is usually caused by external factors such as heavy rainfall, moisture, and humidity, as well as internal factors like leaky taps, faulty pipes, incorrect plumbing, or cracks in sanitaryware. Water seepage can lead to structural damage, as it weakens walls, ceilings, and foundations, and promotes the growth of mould and mildew, which can cause respiratory issues and allergies.
To prevent water seepage, you can take the following steps:
- Grade the soil around your house so that water flows away from the foundation.
- Ensure proper waterproofing of roofs and exterior walls, especially in regions with high rainfall.
- Seal gaps around windows and doors with putty or plaster.
- Waterproof walls during construction or by applying protective coatings or sealants to prevent moisture penetration.
- Regularly inspect plumbing systems, appliances, and fixtures for any signs of leaks, and address even small drips to prevent future problems.
- Clean gutters regularly to prevent clogs and water backup.
- Insulate exposed pipes to prevent freezing and reduce the risk of condensation and leaks.
- Improve ventilation in damp areas, such as bathrooms and kitchens, by using exhaust fans to remove moisture.
If you notice signs of water damage, such as damp patches, discolouration, or peeling paint, take action to repair the leaks and dry the affected surfaces before applying paint designed for damp areas. By addressing leaks and seepage, you can effectively prevent water damage and create a healthier living environment.

Use exhaust fans to remove moisture
Excess moisture in the home can lead to the growth of biological pollutants such as mould, mildew, bacteria, and viruses. These pollutants can cause allergic reactions and spread infectious diseases. To prevent this, it is important to control the relative humidity in the home, which should ideally be maintained between 30% and 50%.
Extractor fans, also known as exhaust fans, are an effective way to remove moisture and improve indoor air quality. They work by pulling air from an enclosed space and expelling it outside through a duct system or vent. This continuous removal of hot, humid, or contaminated air helps to maintain a cooler and healthier atmosphere.
Extractor fans are particularly useful in kitchens and bathrooms, where heat and moisture buildup is common. In the kitchen, extractor fans collect and safely vent steam produced by cooking. In the bathroom, they should be used during and after hot showers to remove moisture-laden air. It is recommended to run the fan for 20 minutes after a shower to ensure adequate ventilation. If your bathroom has a window, opening it during showers can also help improve air circulation.
It is important to note that extractor fans require maintenance and should be regularly cleaned to ensure optimal performance. Additionally, when installing extractor fans, it is crucial to ensure that all vents are directing air outside and not into enclosed spaces, such as walls, crawl spaces, or attics, as this can lead to hidden moisture and mould problems.
By using extractor fans to remove moisture, you can effectively reduce the risk of biological pollution in your home, creating a healthier and more comfortable environment.

Wash sheets and bedspreads in hot water to kill dust mites
Dust mites are a common source of biological pollution in the home. They thrive in damp, warm environments, feeding on skin cells that humans and animals shed. Dust mites are a particular problem in carpets, bedding, and pillows, where they can cause allergic reactions and spread infectious diseases.
To prevent dust mites from accumulating in your bedding, it is recommended to wash your sheets, blankets, pillowcases, and bedcovers in hot water that is at least 54.4°C (130°F). This temperature is high enough to kill dust mites and remove their allergens. If your bedding is made from delicate fabrics such as silk or cotton satin, it may not be suitable for a hot wash. In this case, you can try soaking your bedding in cold water with a mild detergent, then washing it in warm water (approximately 60°C or 140°F).
If you are unable to wash your bedding in hot water, there are alternative methods to kill dust mites. One option is to place your bedding in the tumble dryer for at least 15 minutes at a temperature above 54.4°C (130°F). This method will kill mites and their eggs. Another option is to use a mattress steam cleaner, which can expose your bedding to heat without the need for a hot wash. Set the steamer to between 71°C and 82°C (160°F and 180°F) and be sure to cover the entire surface to effectively kill the mites.
In addition to washing your bedding, there are other measures you can take to prevent dust mites. Using an air purifier can help to reduce the number of allergens in your home, improving air quality. Regularly vacuuming your mattress and using a HEPA filter can also help to collect and trap dust mites and their faeces, which can be difficult to remove due to their sticky nature.

Ensure personal hygiene and avoid cross-contamination with food
Personal hygiene is critical in preventing biological pollution, especially when preparing and storing food. Cross-contamination occurs when bacteria or other microorganisms are transferred between different foods, from food to surfaces, and from surfaces to food. This can cause foodborne illnesses such as food poisoning, influenza, measles, and chickenpox.
To avoid cross-contamination and maintain personal hygiene:
- Wash your hands regularly, especially before preparing, cooking, or eating food.
- Ensure that all surfaces used for food preparation are clean and clear.
- Use separate chopping boards and utensils for different types of food. If this is not possible, prepare fruits and vegetables first, followed by raw meat, fish, or poultry, and wash the utensils with soap afterward.
- Always use a clean chopping board for ready-to-eat or cooked foods.
- Clean as you go—if you spill food or juices, clean it up immediately and thoroughly.
- Avoid using the same bags for raw and ready-to-eat foods. Raw meat, poultry, and seafood should be placed in containers or sealed plastic bags to prevent their juices from dripping onto other foods.
- Do not use sauces that have been used to marinate raw meat, poultry, or seafood on cooked foods unless they are boiled first.
- Rinse fresh fruits and vegetables to remove visible dirt and grime.
- Store eggs in their original carton and refrigerate them as soon as possible.
In addition to personal hygiene and avoiding cross-contamination, there are other measures to prevent biological pollution:
- Control the relative humidity level in your home to minimize the growth of certain biological contaminants. A relative humidity of 30-50% is recommended to reduce the propagation of mould and mildew.
- Ensure proper ventilation and avoid standing water or wet surfaces, which can become breeding grounds for mould, mildew, bacteria, and viruses.
- Regularly wash your sheets and bedspreads in hot water to kill dust mites.
- Keep windows closed to prevent pollen and fungi from entering your home, and air out your space at night instead.
