Mold does not do well at temperatures below 60 degrees Fahrenheit or above 80 degrees Fahrenheit.
The ONLY way to permanently protect your collections from mold is to control the environment by keeping the temperature within 65°-70° Fahrenheit and the relative humidity within 45%-65%. Prevention is the key but if you do experience a mold outbreak there are non-chemical means for clean-up and recovery.
Now that we understand what mold is and the conditions in which it thrives, let's delve into the question: Does heat kill mold? The simple answer is yes. High temperatures (around 140 to 160° Fahrenheit) can deactivate mold spores and prevent them from spreading.
According to the Environmental Protection Agency (EPA), the ideal range of humidity levels is between 30% to 50%. However, if the humidity rises about 60%, then it is considered high and may lead to mold, mildew, and even invite in pests like cockroaches and dust mites!
Even when temperatures drop below freezing, mold spores don't die; they simply become dormant and will begin to multiply and grow again as soon as the temperature rises.
Mold hates light. Other than moisture there's nothing mold loves more than dark places. An easy prevention against mold growth is opening your blinds and shades. If it's warm enough out, open the windows.
Mould will easily grow and spread if the right conditions are present. So, dehumidifiers don't kill mould, but they can help to prevent it from growing inside your home by reducing humidity. However, the best way to deal with it is to get rid of its source.
Appropriate Ventilation
Ensure your house has enough airflow by opening doors and windows to allow a cross-breeze, installing ceiling fans, or employing exhaust fans in bathrooms and kitchens to reduce dampness. This maintains ideal humidity levels by letting damp air escape and allowing fresh air to flow.
Mold in Cold Temperatures
Contrary to popular belief, cold weather does not kill mold, which can and does grow in the winter months. While extreme temperatures can temporarily deactivate mold, it does not die–it just waits for ideal conditions to grow.
Heating can help prevent the growth of mould, but it is not always effective on its own.
Your AC can control the temperature and humidity in your home, which can prevent mold growth. During the hot, humid summers, set your air conditioner between 68 and 72 degrees Fahrenheit. The relative humidity in your house should not exceed 50%.
According to the United States Department of Agriculture (USDA), mold dies when exposed to temperatures between 140 and 160 degrees. So, in principle, yes, you can kill mold in your home with heat.
Mould thrives in damp areas such as windows, where there is dust, dirt or organic material, that's why the number one way to reduce mould is to open your windows regularly. By opening the windows at least once a day, this allows the mould spores to escape and lets patches of moisture dry out.
Your air filter can help to purify the air, removing tiny mold spores. This can be a tremendous help, and soon you'll start to feel more comfortable. Note that not every air purifier can remove and purify mold; you should check to make sure that your air purifier can do the job.
Mold is often described as smelling musty. Others have described mold as having an earthy or meaty odor, resembling the smell of wet socks or rotten wood. For many homeowners, the smell is unpleasant and pungent. As mold grows, it can emit gasses known as microbial volatile organic compounds, or MVOC's.
Spray the area with a mixture of water and vinegar - half water, half vinegar. Next, scrub to remove all traces of the mold. For removal of black and white mold, spray the area with the half water and half vinegar solution.
It irritates the nose and throat, which can lead to both sneezing and coughing as your body tries to get rid of the irritant. Inhaling mold spores can also trigger coughing in people with allergies or an asthma attack, for those with asthma.
Most often, a mold problem will be readily identified by a musty smell that becomes obvious in damp environments. Mold also likes to play hide and seek, so if you suspect there is a problem, then check under carpets, behind drywall, inside ductwork, in between bathroom tiles and in other moisture-prone areas.
