At first glance, filter driers on air conditioning or refrigeration systems are exactly what their name implies - front-line protection designed to filter out contaminants and dry the refrigerant to avoid ice formation and oil degradation. They also, of course, must remove acids formed as a byproduct of moisture, oil, and heat.
But all filter driers are not created equal. And all are not prepared to handle the change and challenge coming with the advent of new environmentally friendly refrigerants.
