There are more than 100,000 types of mold located throughout the world, so if you own a home, there’s a good chance that you will have to deal with at least one of them at some point. While many types of mold are non-toxic and won’t cause any health-related problems, you should keep an eye out for mold symptoms and remove mold as quickly as possible to avoid the risks associated with it. Here are the most common types of mold that homeowners will find during a mold inspection in San Francisco .
Aspergillus 
Do you have bad allergies? If so, you’re going to want to monitor the presence of this type of mold in your home. It is most commonly found inside of air conditioning systems as well as on foods, and it can cause severe allergic reactions for those who have allergies or diseases of the lungs. Because it can grow inside of air conditioning units, it can also spread throughout homes fairly quickly and cause problems for those with allergies.
Cladosporium
This type of mold is not toxic to humans but, much like aspergillus mold, it can cause allergic reactions in some people. It is black and green, looks a little bit like pepper, and grows on everything from air ducts to the back of toilets. It has been known to cause watery eyes, sore throats, and other flu-like mold symptoms in some people.
Stachybotrys Atra
This is by far the worst type of mold that you can find inside of your home. It is commonly referred to as black mold, and it can cause a series of very serious health issues. Specifically, black mold can cause bleeding of the lungs and, in some cases, it can even lead to death. If you even think you might have black mold in your home, you should have a mold test done immediately and then work to remove it from your home. Mold remediation should get rid of it and make the air in your home clean again.
