Filtrete 12x12x1 Air Filter – MERV 11, MPR 1000, 4-Pack

Improve your indoor air with Filtrete 12x12x1 MERV 11 MPR 1000 Allergen Reduction filters

Elevate your home environment with this 4-pack of Filtrete 12x12x1 air filters. Designed for standard 12x12x1 HVAC slots, the actual size is 11.68 x 11.68 x 0.81 inches. The electrostatic Filtrete media works like tiny magnets, attracting and capturing a broad range of airborne particles as air streams through the pleated filter. With each pass, you may notice a perception of fresher air and steadier airflow in common living spaces.

Why this Filtrete filter stands out

The filter combines positively and negatively charged fibers to capture particles across sizes. This electrostatic approach can attract and trap microparticles that commonly circulate in homes — from dust and pollen to pet dander, mold spores, smoke and smog — all while maintaining airflow that supports your HVAC system. The combination of a 1000 MPR rating and a MERV 11 efficiency level provides a balanced filtration solution for many households.

• 1000 MPR Micro Allergen Reduction targets a wide particle range, from visible dust to microscopic irritants.
• MERV 11 efficiency supports solid filtration without overly restricting airflow in most homes.
• Filtrete 3-in-1 technology emphasizes particle capture while letting clean air pass through.

What you may notice in daily life

As air moves through the filter, particulates are captured, which can lead to less settling dust and a clearer look in rooms between cleanings. This sense of cleaner air is complemented by the filter’s role in keeping HVAC components cleaner, potentially contributing to steadier performance over time. While not a medical claim, many users appreciate a calmer, more breathable atmosphere in living spaces where the filter runs regularly.

• Potential HVAC efficiency support as dirt is removed from the air path, which may ease motor strain.
• 4-pack convenience reduces shopping trips and ensures replacements are on hand when needed.
• Versatile usage: suitable for furnaces, air conditioners, or whole-home HVAC systems.

For best results, replace about every 90 days; actual intervals depend on usage and environment. The Filtrete Smart App can help you stay on schedule by sending reminders when it’s time to change the filter — simply scan the packaging to set up notifications. Filtrete is a widely trusted name in residential filtration, offering filtration solutions designed to clean the air you share with family and pets. This 4-pack is an easy-to-store option that supports ongoing maintenance without sacrificing airflow or comfort.
