Will Opening Windows Reduce Mold? What to Know
No homeowner wants to deal with mold. This fungus is unsightly and can ruin your property. It can even pose a threat to your health.
So, how can you reduce mold in your home?
One of your first instincts might be to open a window. In this post, we’ll go over whether or not this is an effective method. We’ll also share other great ways to control mold in your home.
Does Opening Windows Help Reduce Mold?
As you might’ve guessed, opening windows can help reduce mold. Doing so lets excess moisture flow outside instead of settling on your walls, floors, and ceiling. Without the proper amount of moisture indoors, mold won’t be able to grow.
Opening windows can be helpful. However, you should know that this method is not the magic bullet. It won’t be effective in cases where:
- The relative humidity outside is greater than 60%. If it’s humid outdoors, opening your windows will only bring in more moisture (especially if it’s hot outside). You’ll have to use other methods to control your indoor humidity. We discuss these other methods later on.
- It’s raining outside. If it’s raining outside, you’ll only be inviting more moisture into your home.
- You are dealing with a severe case of mold. You might be able to take care of minor cases on your own. But, if you’re dealing with a severe case, opening your windows won’t be very effective. You should contact a professional remediation company like All Dry USA. Our team will address the root cause and remove mold colonies.
So, before throwing your windows open, consider whether you have a minor or severe case on your hands. And, if your case is minor, ensure the outside humidity is low. This will allow moisture to flow out properly.
Why Opening Windows Can Help You Control Mold
To understand why opening windows can help control mold, let’s define mold.
Mold is a fungus that consists of microscopic spores. These spores exist pretty much everywhere and are usually harmless.
Spores become problematic when they land on a damp spot in your home. The moisture allows them to grow and multiply.
We know that spores thrive in warm, damp environments. You’ll need to reduce the amount of moisture in your home to prevent mold growth.
Opening windows can be a great way to reduce moisture (as long as the humidity outside is below 60%). It draws out excess water, making it difficult for spores to flourish.
Opening windows is particularly effective in kitchens and bathrooms. These rooms are prone to mold growth because of excess moisture. When you boil a pot of water or take a shower, water droplets condensate and cling to your walls. Your A/C removes much of the moisture but opening your windows will help pick up some of the slack.
Other Methods To Reduce Damp and Control Mold
Opening your windows isn’t always the best method. As we mentioned earlier, it won’t be effective if the humidity outside is greater than 60%. You also can’t open your windows if it’s raining, too cold, etc.
So, what if you can’t open your windows? Are there other effective methods for controlling humidity and mold in your home?
Luckily, the answer is yes. Here are some of the best methods:
- Get a good dehumidifier.
- Buy plants that wick moisture.
- Move moisture-releasing plants outside.
- Don’t air-dry clothes inside (use a dryer or air-dry your clothes outside).
- Turn on fans when you cook and shower.
- Purchase charcoal bags, which absorb moisture (you can also make moisture-absorbing bags out of silica gel packs or rock salt).
- Fix any leaks your home might have.
- Ensure that your home’s ventilation system is working properly.
Important note: When you hear that moisture can cause mold, you might want to eliminate any water exposure in the area. Keep in mind that your home needs to have some humidity (around 30-50% is ideal). If the humidity in your home is too low, you might experience dry skin, irritated nasal passages, etc.
You can test your home’s humidity using a hygrometer. This thermometer-like device is available at most hardware stores. If the humidity is too high or too low, you can make the appropriate adjustments, which will help prevent mold and ensure you are comfortable.
Frequently Asked Questions
Should I open windows if I have mold?
Yes, but only under these conditions: the outside humidity is under 60%, it is not raining, you only have a minor case of mold. Otherwise, mold will feed off the damp air.
Can fresh air get rid of mold?
No, but it will keep the mold from growing. Keep your windows open before, during, and after cleaning the affected areas. Wait until it is all dry before closing the windows.
Will opening a window help with damp?
Yes. An open window that provides a cross breeze will quickly dry out any damp in your home. As always, make sure it is dry outside, or you will only exacerbate the issue.
Opening your windows helps reduce mold growth by drawing moisture out of your home. However, it won’t necessarily eliminate the fungus.
