Filtrete 14x24x1 Air Filter, MERV 11, MPR 1000 – 4-Pack (Actual Size 13.68 x 23.68 x 0.81 in)

Cleaner air for a more comfortable home

The Filtrete 14x24x1 Air Filter combines MERV 11 performance with MPR 1000 microparticle filtration to help capture common household pollutants as air circulates through your HVAC system. This 4-pack is designed for long-term use and is sized for compatibility with many standard 14x24x1 units. The actual size is 13.68 x 23.68 x 0.81 inches, which supports a snug fit and reliable airflow in busy living spaces.

Designed by 3M’s Filtrete technology, the filter uses electrostatic fibers that work like tiny magnets to attract particles. With every pass, air moves through a pleated media that targets a broad range of airborne contaminants, including dust, pollen, pet dander, and smoke byproducts. While performance varies by home, you may notice a sense of freshness in rooms that see daily activity.

How the electrostatic design helps

The filter’s combination of positively and negatively charged fibers increases particle capture, especially for smaller particles that can irritate eyes, noses, or breathing passages. This electrostatic action is said to outperform non-electrostatic fiberglass and certain washable filters, helping to reduce the concentration of fine irritants in indoor air.

• Attracts and traps a wide range of microscopic particles so air feels cleaner on every pass.
• Supports HVAC efficiency by limiting dust buildup on internal components, potentially easing system operation.

What you get in this 4-pack

• Four 14x24x1 filters with a 3-month recommended replacement interval.
• Compatibility with most furnace and central AC systems that use 14x24x1 filters.

Real-world use and practical benefits

In homes with daily activity such as cooking, cleaning, or pet movement, these filters help capture lint, dust, pollen, and pet dander as air circulates. The 1000 MPR rating indicates strong microparticle handling, which can contribute to a sense of cleaner air between replacements. Replacement timing varies by environment, so consider monitoring air quality and usage to determine the best schedule for your household.

Additional notes include a certification indicating asthma and allergy-friendly properties on the packaging and the ability to use Filtrete’s Smart App to set replacement reminders. While results differ, many users appreciate the ease of maintenance and consistent airflow when filters are fresh.

Tips for best results

• Change filters every 90 days for optimal performance as recommended.
• Use the Filtrete Smart App to track replacement dates and maintain steady airflow.
• Ensure proper fit by confirming the actual size matches your unit’s filter slot.
