Ventilation is critical to home comfort. Proper ventilation prevents air pollutants from affecting the health of you and your family. Not only that, having airflow in your home can get rid of any unwanted smells, such as from cooking or pets. It is also good to have an airflow that is uninterrupted, as anything blocking the air flow in your home can cause damage to both your home and your health.
One of the reasons ventilation is so important is because it controls how much moisture is lingering in your home. If you have adequate airflow throughout your home, your walls, floors, and all the wood in your home will stay dry and not collect moisture. Wood can rot when exposed to moisture, as can drywall. If you let moisture build up in these areas of your home, they will not only destroy the structural integrity, but they will also cause mold to build up. Mold can have a number of negative effects on your health if you are exposed to it for a long time.
If you’re not exposed to mold for a long time, you might notice some minor symptoms, such as irritation to your nose, throat, and eyes. You might possibly develop a headache or a fever if you’re exposed for a longer period of time. Mold can both cause immune system problems and worsen the symptoms for someone who already has an autoimmune disease. Prolonged exposure to mold can result in respiratory damage that can’t be reversed, such as asthma. If you have proper ventilation in your home, you won’t have to worry about mold forming.
There are three ways you can provide ventilation to your home. You can choose to have natural ventilation. This is when air enters your home through windows, doors, and even cracks and holes in the walls of your home. If you live in an old home, it’s likely that air is entering your home even when you have the windows shut.
Spot airflow is when you use exhaust fans or other forms of pushing air in or out of your house in certain spots. Typically, you might have an exhaust fan over your stove or in your bathroom.
You can also have air ducts installed around your whole home to provide airflow throughout your home. There are three different ways air is moved through your home when this method of moving air is used. The exhaust airflow system pushes inside air to the outside of your home. The supply air system brings air into your home. Then, there is a balanced system of air that moves air in and out of your home. If you have one of these air systems, it’s important to keep it maintained so it doesn’t get blocked and allow air pollutants to lurk in your home.
