Cleaner air starts with Filtrete 20x24x1

The Filtrete 20x24x1 air filter, crafted by 3M, combines a powerful depth of media with proven filtration science. With a MPR 1000 rating and MERV 11 efficiency, this two-pack is designed to pull in a broad range of particles as air passes through the filter, supporting a fresher-feeling living space without sacrificing airflow.

What’s inside and how it helps

This 2-pack delivers three months of filtration per filter, offering a practical renewal cycle for busy households. The pleated design captures both large debris—dust, pollen, lint—and smaller micro-particles that can accompany daily life, pets, and urban environments. The result is a balance between clean air and consistent airflow for your furnace, air conditioner, or central HVAC system.

• Two 3-month filters for a straightforward renewal cadence
• Optimized for furnaces, air conditioners, and whole-house HVAC systems

Exclusive Filtrete technology

The 3-in-1 Filtrete technology pulls in and traps particles, allowing cleaner air to move through the filter. This approach aims to maintain airflow while reducing the presence of many common airborne irritants in everyday settings.

With a 1000 MPR rating and MERV 11 rating, the media is designed to capture countless microparticles as air flows through the filter media, contributing to a potentially fresher indoor atmosphere.

• Captures pet dander, pollen, dust, and smoke-related particles
• Maintains airflow while trapping a broad spectrum of contaminants

Real-life use and benefits

In homes with pets or in urban locales, you may notice fewer floating dust motes and a sense of improved air quality during daily HVAC operation. The filter is designed for compatibility with most central heating and cooling setups, making it a practical upgrade to your current filtration system.

Keep in mind that individual results depend on your home environment and usage. While not a medical device, many households appreciate the potential for a cleaner-feeling living space and easier maintenance of their HVAC system.

Maintenance and smart reminders

For optimal performance, replace each filter at least every 90 days. The Filtrete Smart App lets you scan the packaging barcode and set 30-, 60-, or 90-day reminders, so you’ll receive a notification when it’s time to swap the filter.
