-
Our Gold Frame filters are more durable and rigid than the Silver Frame filters.
-
All filters are UV protected, EXCEPT for our Gold Frame 82% and Silver Frame 82% so if you have a UV purifier light installed in your air system, be sure to avoid the Silver or Gold 82%.
-
The 94% and 82% refer 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 (82%) but allow more airflow (they are less restrictive and less taxing on the your HVAC system).The 94% is recommended for all applications except in systems that have a reduced sized return opening.
