How can I improve the air quality in my home?
Here’s a list of ways to improve your indoor air quality at home
You can check the quality of the air with indoor air sensors. They can measure humidity, particulate matter (PM), air temperature, VOCs, carbon dioxide and, other gases in the air. Based on the results, you can make choices on what to change in your home, for example changing how you heat your home.
While it’s not possible to eliminate every risk, you may want to try the following handy tips:
Keep rooms well-aired
Open your windows for 5-10 minutes several times a day, especially if you’re cooking or using the shower. Keeping your space well-ventilated is especially important if you’re having building work done too. Keeping your windows open also reduces risks from viruses, such as the coronavirus.
Try to avoid opening your windows at peak times of traffic. You can also check your local outdoor air pollution levels.
Use allergy friendly or chemical-free products
These will have lower levels of VOCs and are usually fragrance-free.
Use solid or liquid cleaning products
Unlike sprays, these won’t get into the air for you to breathe in.
Prevent condensation
Dry washing outside or in a tumble drier. If you can’t do that, try a well-ventilated room or airing cupboard. You could also consider using an extraction fan in the kitchen and bathroom. This will prevent damp and mould.
Keep your home warm
By keeping your home between 19°C and 21°C in colder months, you can prevent condensation.
Fix any leaks or water damage
This reduces high humidity and prevents mould.
Keep your home smoke-free
Don’t smoke indoors and don’t allow others to smoke in your home. If you smoke, the best thing to do to improve your health is to quit. If smoke from your neighbours is affecting you, try asking them to smoke somewhere else. If you explain your situation, they may be understanding.
Use electric or gas heating
Cook and heat your home with electric and gas instead of burning wood and coal. Remember to use an extraction fan or open windows when cooking.
Vacuum regularly
Vacuum your home if you’re allergic to anything. You may even want to consider replacing carpets with wood or laminate flooring. You can also wipe dust using a damp cloth to avoid dust going into the air.
