Frequently Asked Questions
How often should I replace my Dometic AC air filter?
We recommend replacing your micro air filter annually or every 12 months of use. If you travel in dusty environments or use your AC frequently, consider replacing it more often to maintain peak efficiency.
Will this filter fit my specific RV model?
This filter is designed for Dometic AT15 and AT18 rooftop air conditioning units. Check your AC unit's model number on the exterior shroud to confirm compatibility before ordering.
What happens if I don't replace a dirty air filter?
A clogged filter restricts airflow, forcing your AC compressor to work harder, reducing cooling efficiency, increasing energy consumption, and potentially shortening the lifespan of your air conditioning system.
