What is the maximum refrigerant charge for appliances covered by EPA Type I certification?

The main idea is that Type I certification covers small appliances that contain 5 pounds of refrigerant or less. This 5-pound limit exists because smaller systems pose a lower environmental risk when recovering refrigerant, and the required recovery equipment and procedures are simpler for these appliances. If an unit has more than 5 pounds of refrigerant, it typically falls under the scope of Type II or universal certification, which involve larger or higher‑pressure systems and stricter handling requirements. In practice, many window units and small dehumidifiers stay within this limit, which is why the maximum charge for Type I is 5 pounds (2.27 kg) or less.
