How Long Should You Air Out Your House For? Fifteen minutes to half an hour is what you should aim for. The air in your home has pollutants at any given time, so that should be enough time to get rid of them. It's important to give your home a chance to let good, clean air in.
Prevailing wisdom is that at least 5 minutes—and ideally 15 to 20 minutes—a day of ventilation significantly improves indoor air quality. For a strong ventilation, open the front and back door, along with windows on the path in between, to get the baddies out.
Fifteen to 20 minutes is preferable. However, when you open them is also important. Keep them open at night or in the early morning, when the weather is cooler.
Proper ventilation keeps the air fresh and healthy indoors. Like the lungs, homes need to be able to breathe to make sure that fresh air comes in and dirty air goes out. Air indoors can build up high levels of moisture, odors, gases, dust, and other air pollutants.
Fresh air not only cleans your lungs, it can also boost your mood, lower your heart rate, increase energy levels and even improve digestion (yes, that's right). Florence Nightingale knew the benefits of fresh air long before any scientific study.
Removes dust
No matter how clean you keep your home, dust always settles, and more so throughout the night without family members moving about. Fresh air lifts this dust and prevents dustballs from forming. It helps move dust from those hard-to-reach places into the limelight to be sucked up later by your vacuum.
Airing out your house once a day will make a world of a difference. If you live in a highly polluted urban area, however, you may consider doing it every other day. Otherwise, doing it daily is ideal, especially if there are a lot of people in your home or there's somebody with respiratory issues.
Well as simple as it sounds, a short burst of fresh air daily significantly reduces indoor pollution, bringing in fresh air to dilute emissions from indoor sources and simultaneously carrying indoor air pollutants out of the area.
Ventilating is important all year round. During the winter months, you should open your house at least once a day, no matter how bitterly cold it is outside. It doesn't have to be for long, opening a window or door for even just a few minutes will create a cross-draught.
Keeping your windows shut all day will allow chemicals and allergens to build up inside. Even if you live in a polluted city, you are going to have to open the windows from time to time. “You don't want to be stuck in a house with no ventilation all day,” says Dr Paul Young of Lancaster University.
Keeping a window open reduced concentration of carbon dioxide, volatile organic compounds, and some particulate matter in participant bedrooms. People slept better. Keeping a door open also reduced carbon dioxide concentration, without a direct correlation to improving sleep.
Keeps mold and mildew out by reducing condensation
Over time, the condensation will build up on walls and windows. It can damage the wood and contribute to mold or mildew growth. Airing out your home daily will ensure that the moisture leaves your home before mold forms. It's important to catch the condensation early.
Ventilate briefly but intensively. By opening the windows wide, we help the air exchange occur faster and prevent excessive cooling. In the winter months, about 5 minutes is enough to provide our rooms with the right amount of fresh air. Avoid draughts.
This measure describes how often the air in a particular space will be replaced. In an energy-efficient home, that number should fall below 0.50 ACH. However, building guidelines suggest a minimum 0.35 ACH, regardless of whether the air enters the home through fans or is a result of natural air leaks.
It is also very important that there is adequate ventilation in the room. Open a window or door so the mold spores can escape, instead of staying locked in your home.
Since moisture is one of the main risk factors in developing mold, installing new windows is an efficient solution to combating the mold growth inside your home.
Ventilate your home
Mokler recommends even opening the windows for just 20 minutes a day as this can be enough to drastically reduce the effects of condensation and dampness in homes.
Signs of Poor Ventilation
Windows and glass that appear frosted due to condensation. The discoloration of floor, wall tiles, and grout. Early signs of rust stains on plumbing. Mold growth on structural surfaces like walls and wood.
You should place outward-facing fans on the warmer side of your home to blow the hot air out and inward-facing fans on the cooler side to draw cool air in, says Barry Jacobs, vice president of product development at Comfort Zone, a home environment product company.
Occupants of homes with poor indoor air quality may complain of symptoms such as headache, eye irritation, fatigue, dry throat, sinus congestion, dizziness, and nausea. Because many illnesses can cause these symptoms, diagnosing sick building syndrome is difficult.
A buildup of dust in your home is often the result of poor airflow. A combination of poor airflow and infrequent cleaning can lead dust and dust mites to settle comfortably into several areas in your home. “Dust mites live in mattresses, pillows, and upholstery,” Dr. Cajigal says.
Even those times when you're feeling busy and rushed, you should make it a priority to spend at least 20 minutes outside every day. It's free, easy, and single-handedly one of the most beneficial things we can do for our overall health and wellbeing.
