Know before you buy
The nominal size of 20x25x1 is the industry-standard label used for sizing, while the actual dimensions are 19 1/2" x 24 1/2" x 3/4". Always measure your current filter or your HVAC slot to ensure the actual dimensions will fit properly.
These filters are designed to last up to 90 days under normal conditions. Depending on your home environment—such as the presence of pets or high dust levels—you may need to check them monthly to see if they require an earlier change.
A MERV 13 rating indicates high-efficiency filtration capable of capturing smaller particles like smoke, bacteria, and virus carriers, in addition to common allergens like pollen and pet dander. It is a significant step up from standard fiberglass filters, providing much cleaner indoor air.
Yes, these filters are constructed with a robust beverage board frame that is designed to resist humidity. This helps the filter maintain its structural integrity and prevents it from collapsing or warping within your HVAC system.
These filters are compatible with most standard HVAC systems that require a 20x25x1 inch filter. However, because MERV 13 filters are denser than lower-rated options, ensure your system's blower motor is capable of handling the increased airflow resistance before installation.
