There can be many reasons we want to increase the airflow in our homes:

  • Moving into a new home.
  • Maybe the house is lived in by an elderly person and needs freshening up.
  • Perhaps the house smells of mold.
  • Perhaps you’ve had a gas leak.
  • Maybe you’ve burnt some cookies.
  • Maybe you’ve had a fire damage.

There are all sorts of reasons we need to ventilate and air out a house in the winter.

Maybe you’re just the type of person like me, who likes to have fresh, outdoor air in the home every day, even in December! Anyone who knows me knows that I prefer having a home that smells of nothing but fresh air to a house smelling of cleaning products, strong chemicals, and stale air.

It’s easy to change the air in your rooms when it’s warmer weather between March and September, but how do we air them out in the winter months when it’s cold, and should we open windows when the heating is on?

The question I get asked in my Facebook group is, “should you open your windows when the heating is on?” It’s a tricky question as we all love to have a warm house, but do we really want all that heat to escape through the windows?

How to air out a smelly house in the winter.

I used to open one window and leave it open all day long, hoping it would change the air. I ended up with a freezing cold house and not much airflow. There was no fresh air because I’d close the door to stop the cold air from spreading, so the air wasn’t moving, there wasn’t any fresh air in the house, and the atmosphere remained stagnant. All I was doing was losing heat and wasting energy rather than changing the air quality.

When airing out a house, we need to open windows to create a through-draught to make as much airflow as possible and exchange the outside air with the inside air in the shortest time possible.

I needed to know how to pull air through the house and get rid of any smells out of the house without losing heat and energy.

 Consider what happens when you open the front, back, and internal doors. the doors slam ferociously because you’re causing a massive through draught. You’re forcing the air to move through your house at high speed, and that’s exactly what I needed to recreate with my windows.

How to circulate air in a house

  1. Open all the windows

    Open every window and door upstairs in your home to allow a steady stream of air to circulate. Wait until every member of your family has showered to ensure that the humidity can leave. It’s beneficial to do this in the morning because it changes the air from the night before and removes any damp atmosphere from people having showers in the morning. My whole family likes to shower first thing in the morning, and the bathroom is often humid. Windows are always steamy.
    Opening the windows will allow the dampness to disappear, shower curtains to dry, windows to dry, preventing the house from becoming moldy.

  2. Set a timer

    Set a timer for three minutes and leave the air to circulate. This is how to circulate airflow to one room without losing too much heat.
    I flung all of my windows wide open and set my timer for three minutes. I couldn’t believe the amount of air that swept through the house in such a short period. It felt so fresh and invigorating.

  3. Close all the windows

    After three minutes, close all the windows. We do not want to lose any more heat. You have changed the air, freshened the rooms, and got rid of any moisture in the air. It is now time to close the windows.

  4. Repeat steps 1-3

    Repeat steps 1-3 a couple of times a day and once before going to bed for fresh house air circulation. This three-minute trick a couple of times a day will make a difference to your home’s freshness.
    Try starting with the upstairs windows, then once you’ve mastered that, try opening all the windows in the house for a few minutes and see what a difference it makes. Make sure you don’t open the downstairs windows unless you are staying downstairs. You don’t want burglars to come in through an open window.


The benefits of opening your windows and changing the air.

  • Helps to stop black mold from growing and spreading . In the winter, a low temperature attracts more humidity within the house. This can cause black mold to grow in bathrooms, walls, and window frames. Black mold can be hazardous to people with respiratory problems, allergies, or asthma. Black mold can also affect the immune system, making existing skin problems such as eczema worse. It can cause sneezing, runny noses, red eyes, and skin rashes, so you want to minimize the likelihood of black mold in your home. If you think you have a problem with black mold that you cannot control, call out the professionals. You can read more about the dangers of black mold here. Mold doesn’t grow where there is free-flowing dry air. Moud prefers damp environments which are the perfect breeding ground for the spores. Keep the air circulating several times a day, especially after showers, baths, and cooking, to help your home stay mold-free.
  • Ventilation gets rid of condensation and reduces humidity because cold air holds less water and takes up extra moisture from inside your house.
  • You feel invigorated When you have fresh air in the home, you feel less sluggish, and it makes you want to get up and do more.
  • Your home smells fresh. Having cleaner air prevents the house from smelling musty and damp.
  • You save money. Because you do not need to buy lots of cleaning products to keep your home smelling fresh, so you save money in the long run. People often ask me how to clean the air in my home naturally, and I tell them that you shouldn’t use air fresheners, smelly candles, and wax melts to make your home smell better, as it is bad for the environment . Fresh air smells so much better than any other product that you can buy. Next time you’re tempted to pick up the air freshener, put it back on the shelf, don’t buy it, go home and open your windows instead. You won’t be disappointed.
