The Invisible Threat: Mold Spores

Beyond Allergies: Mycotoxins and Health Risks
Some molds produce mycotoxins. These are toxic compounds that can cause more serious health issues than simple allergies. They can affect your immune system and lead to chronic illnesses. Exposure can be particularly dangerous for children, the elderly, and those with pre-existing respiratory conditions. This is why it’s so important to take mold seriously.
