Frequently Asked Questions

This compact unit starts producing up to 340 BTUs of heat when you plug it into your boat or car cigarette lighter plug. The head and base can rotate up to 360°, so the heat can be directed anywhere needed, such as onto your feet or a fogged-up windshield. 

The unit's effectiveness can be impacted by external factors, such as the level of condensation, outside temperature, and the length of time the Defogger has been running. The Fairview Defogger is a portable device intended for defogging localized areas.
