Know before you buy
The actual dimensions of this filter are 19 3/4" x 20 5/8" x 5". It is designed as a direct replacement for Trion Air Bear, Quality Filters, and Skuttle models, but you should always measure your current filter or housing to ensure a precise fit.
Choose based on your specific needs: MERV 8 is excellent for standard dust and pollen, MERV 11 adds protection against pet dander and smoke, and MERV 13 is the best choice for capturing finer particles like bacteria and virus carriers.
Because of its high-capacity, deep-pleat design, this filter typically lasts longer than standard 1-inch filters. Depending on your home environment and usage, most residential systems will require a replacement every 6 to 12 months.
While higher MERV ratings provide better filtration, they can increase resistance to airflow. If you have an older or sensitive HVAC system, ensure your blower motor is rated to handle the increased filtration density of a MERV 13 filter.
Yes, this filter is compatible with various systems that require a 20x20x5 filter, including specific Lennox and Skuttle models. Always verify your system's manual or the part number of your current filter to confirm compatibility.
