When mold spreads across a home, it can cause health issues like congestion, coughing and sneezing, as well as respiratory infections and worsening asthma and allergies. Mold grows in damp conditions so, if your home is affected from it, investing in a dehumidifier might be the quickest solution.
Understanding what a dehumidifier does will help explain why exactly they help with mold. The short answer is: they remove moisture from the air, and mold needs moisture to grow and spread.
