How to manage your lung condition well

Prevent condensation and keep rooms well-aired

Keeping your rooms well aired by opening windows when you can, can help to protect you against different types of indoor air pollution.

How to keep your home well-aired and prevent condensation

  • Open your windows to ventilate your home. You do not have to have your windows open all the time, you could just open them for a couple of minutes throughout the day. Check the air pollution and pollen levels before opening windows if these are triggers for you. 
  • You can also use extractor fans to ventilate your home. Make sure you clean extractor fans in your bathroom and kitchen regularly so they work effectively.
  • If you have trickle vents, keep them open as much as possible. A trickle vent is a small opening in a window or door that lets fresh air in even when the window is closed.
  • If you can, dry washing outside. If you can’t do that, try a well-aired room, airing cupboard or tumble dryer.  
  • Fix any leaks or water damage in your home, as this will help to prevent humidity that causes condensation. If you rent, tell your landlord as soon as you notice any leaks or water damage. Citizens Advice have more information about reporting damage to your landlord.
  • De-humidifiers can also help to prevent condensation. However, they can make the air too dry and cause you to cough. A good de-humidifier will allow you to set a well-balanced humidity level.

Use sprays and aerosols safely

Using sprays and aerosols safely

  • Where possible, use spray and aerosol products with the window open or in a well-aired space. 
  • Read the labels and instructions on cleaning products before you buy them. If possible, try to buy products with an Air Label certification.
  • Try to choose products with pump sprays instead of aerosols, because aerosols give out more VOCs. 
  • Pick unscented products or products without added scents where possible. 

Keep your home warm

By heating your home to at least 18°C in colder months, you can prevent condensation, damp, and mould.

Vacuum regularly

Vacuuming your home regularly could help if you have allergies. You may even want to replace, or ask your landlord about replacing, carpets and rugs with wood or laminate flooring. Dusting with a damp cloth will help stop dust getting into your mouth and nose.

Vacuum cleaners with HEPA (High Efficiency Particulate Air) filters can trap more house dust mites than normal vacuum cleaners.
