Our Gold Frame filters are more durable and rigid than the Silver Frame filters. Also, the Gold Frame filters are resistant to UV Light, so if you have a UV Air Purifier in your system, you should purchase a Gold Frame Filter. The 82 and 94 refers to the efficiency of the filter and resistance to airflow. The 94 filters are the most efficient (94%) while the 82 filters are less efficient but allow more airflow (they are less restrictive). The 94 is recommended for all applications except in systems that have a reduced sized return opening.
