Know before you buy
The nominal size (20x20x1) is the industry-standard label used for shopping, while the actual size (19.5x19.5x0.75) represents the precise physical dimensions. Always measure your current filter or filter slot to ensure the actual size will fit your specific unit.
MERV 13 is a high-efficiency rating that captures smaller particles like bacteria and smoke. While excellent for allergy sufferers, ensure your HVAC system's blower motor is powerful enough to handle this level of filtration, as higher MERV ratings can sometimes restrict airflow if the system is not designed for them.
For optimal performance and to maintain proper airflow, you should replace these filters every three months. If you have pets, live in a dusty environment, or run your system constantly, you may need to check them sooner.
Yes, these filters are unidirectional. Look for the arrow on the frame of the filter, which indicates the direction of the airflow; the arrow must point toward your furnace or air handler.
Yes, the MERV 13 rating is highly effective at trapping common household allergens, including pet dander, mold spores, pollen, and dust mites, making them a strong choice for improving indoor air quality.
