The 20x25x1 MERV 8 air filter is designed for compatible residential and commercial HVAC systems. This 6-pack provides a convenient supply of replacement filters for air conditioners, furnaces, and other heating and cooling equipment that uses a 20x25x1 nominal filter size.

With pleated synthetic media and an electrostatically charged design, these filters provide filtration for common airborne particles while maintaining airflow through the HVAC system.

Reliable Filtration for AC and Furnace Systems

These MERV 8 pleated AC furnace air filters, 6 pack are designed to capture dust, mold spores, pollen, lint, pet dander, hair, and other airborne debris.

The filtration media is made from a mechanical blend of synthetic fibers and achieves a MERV 8 rating according to the ASHRAE 52.2 test standard. The filter also has a low pressure drop and high dust-holding capacity.

Built for Regular HVAC Use

A two-piece frame provides rigidity and durability, with double-wall thickness around the outer edge. Industrial-grade beverage board is used on both sides of the frame for added structural support.

The electrostatically charged pleats increase the available filtration surface and are designed to capture particles effectively. Compared with standard fiberglass filters, the construction is designed for a longer service life.

Check the Size Before Ordering

The nominal size is 20x25x1, while the actual measurements are 19-1/2 x 24-1/2 x 3/4 inches. Since nominal and actual dimensions can differ, checking the current filter before ordering is recommended.

This filter is suitable when the HVAC system calls for a 20x25x1 nominal filter. Confirming the required dimensions and filtration rating can help ensure the replacement is appropriate for the equipment.

    Good filters, good price

    Local stores, even Walmart, charge much more for equal or inferior filters. This is my second order and I have found no reason to go anywhere else. These are electrostaticly charged, which not all filters are. That is important.

Frequently Asked Questions

  • What furnace uses a 20x25x1 filter?

    • A filter for furnace 20x25x1 is designed for furnaces and HVAC systems that require this nominal filter size. Since filter sizes can vary between equipment and installations, check the dimensions printed on your current filter or refer to the furnace manufacturer’s specifications to make sure a 20x25x1 replacement fits properly.

  • Which 20x25x1 filter should I use for my furnace?

    • The appropriate 20x25x1 filter depends on the furnace's required dimensions and filtration rating. This MERV 8 option is suitable for systems specified for a 20x25x1 filter and compatible with MERV 8 filtration. Check the existing filter and equipment recommendations before selecting a replacement.

  • What is the actual size of a 20x25x1 filter?

    • The actual dimensions of this filter are 19-1/2 x 24-1/2 x 3/4 inches. The 20x25x1 measurement is the nominal size used to identify the filter. Comparing these actual dimensions with the existing filter can help confirm that the replacement will fit the available filter slot.

  • How often should a 20x25x1 MERV 8 filter be replaced?

    • This filter is suggested for replacement at least every three months. The appropriate interval can vary depending on HVAC usage, indoor conditions, and airborne particle levels. Regularly checking the filter can help determine when replacement is needed and support consistent airflow through the heating and cooling system.

  • What does MERV 8 mean on a 20x25x1 filter?

    • MERV 8 identifies the filter's filtration rating, while 20x25x1 represents its nominal dimensions. The MERV rating classifies particle filtration performance under standardized testing. This filter uses synthetic media engineered to achieve MERV 8 performance according to the ASHRAE 52.2 testing standard.

  • Is a 20x25x1 MERV 8 filter suitable for an air conditioner?

    • A 20x25x1 MERV 8 filter can be suitable for an air conditioner that specifies this filter size and filtration rating.
