All air filters have a nominal size and an actual size.
The nominal size is rounded up to the nearest whole or half inch, and printed in a larger font.
The actual size is an exact physical measurement of the filter, printed in a smaller font.
20x23x1
Actual 19.50x22.50x0.75"
If the sizes printed on your current filter match the sizes shown above, this is your filter.
If your previous filter does not have dimensions printed on the frame, use a tape measure and record the length x width x depth. Then, round up to the nearest half inch to find the corresponding nominal size.
MERV 11 filters improve indoor air quality and ensure an efficient HVAC system by removing 95% of airborne pollutants while maintaining proper airflow.
These filters capture dust, lint, debris, mold, pollen, pet dander, dust mites, and auto emissions making sure they do not collect on your evaporator coil, in your furnace, or air ducts.
Filterbuy filters are more durable and effective than traditional fiberglass filters.

Our family-owned and operated company has evolved since its inception in 1958 to the filtration business that you know and love today. As our team has grown to nearly 1,000 employees, we have continued to keep our commitment to community investment and personal aid at every opportunity.

Installation is simple. Each filter has an airflow arrow printed its side. This arrow must match the direction of the air when the filter is placed in your furnace or central air return ducts.
