The 3M Filtrete Dust Reduction 16x25x1 air filter has a Microparticle Performance Rating (MPR) of 300, which is equivalent to a MERV 5 rating. This electrostatically charged filter is engineered to capture large airborne particles such as household dust, lint, dust mite debris, and pollen, helping keep your HVAC system cleaner and your home's air fresher.

3M recommends replacing the Filtrete Dust Reduction 16x25x1x1 filter every 3 months for optimal performance. However, replacement frequency may vary depending on factors such as pets, smokers in the home, local air quality, and HVAC runtime. Since this product comes in a 4-pack, you receive a full year's supply of filters when following the recommended 3-month replacement schedule.

The actual dimensions of this 3M Filtrete Dust filter are 15.7" x 24.7" x 0.8" (nominal size 16x25x1). The nominal size is the industry-standard labeling, while the actual size reflects the true measurement for precise fitment in your furnace or air conditioner. Always verify your HVAC system requires a 16x25x1 filter before purchasing.

This 3M Filtrete Dust 16x25x1 filter is specifically designed to attract and capture large airborne dust particles, lint, household dust mite debris, and pollen using exclusive 3M electrostatic technology. It is ideal for homeowners looking for basic dust reduction. For allergens, smoke, or pet dander, consider upgrading to a higher MPR Filtrete filter.

The 3M Filtrete Dust Reduction 16x25x1x1 filter fits standard forced-air furnaces and central air conditioning systems that require a 16x25x1 nominal-size filter. Its low airflow resistance makes it suitable for most residential HVAC systems without straining the blower motor. Always check your system's owner's manual to confirm the correct filter size and MERV compatibility before installation.
