A healthier car starts with moisture awareness.
 
Your car may seem clean on the surface, but moisture can become trapped in seats, carpets, floor mats, air-conditioning systems and hidden cavities. When moisture combines with organic material such as food crumbs, pet dander, dust, leather, fabric or water-damaged items, it can create the conditions for mould growth.
 
This practical guide was created by Triin-Liis Treial, Certified Building Biologist and founder of House Healing Solutions, to help you understand the common causes of mould in cars and the everyday habits that can help reduce the risk.
 
Inside, you’ll learn how to identify moisture risks, clean your car more safely, reduce dampness, avoid common mistakes and know when the issue may require further investigation.
This is not a fear-based guide. It is a calm, practical resource designed to help you make informed decisions about your car’s indoor environment.
 
This guide is for you if:
You are a parent, soon-to-be parent or caregiver concerned about air quality
You or someone in your household is chemically sensitive, environmentally sensitive or prone to respiratory irritation
