Refresh the air in your home with Filtrete’s 20x20x1 AC Furnace Filter. This 1-inch pleated filter uses exclusive Filtrete 3-in-1 technology to strike a balance between strong particle capture and steady airflow. With a MPR 1000 rating and a MERV 11 designation, it’s designed to pull in a broad range of particles while keeping your HVAC system moving efficiently. This filter is sold in a 6-pack and is sized for standard residential units, so you can stock up and replace on schedule.

In everyday living, you’ll notice the tactile difference of cleaner air and less surface dust, especially on days with outdoor smoke, pollen, or pet dander in the air. Filtrete also targets larger irritants like lint and dust, helping maintain a fresher feel in common living spaces. The 1-inch format is ideal for many standard home systems, providing a practical balance between filtration efficiency and airflow.

The Filtrete 3-in-1 Advantage

• Exclusive 3-in-1 technology traps particles while preserving clean air flow.
• High 1000 MPR and MERV 11 ratings imply enhanced filtration for everyday environments.
• Filters both large particles (dust, pollen, lint) and microparticles (pet dander, smoke, smog).

Real-World Use and Maintenance

• Designed for residential furnaces, air conditioners, and HVAC systems for straightforward replacement.
• Replace every 90 days for optimal airflow and system efficiency, or as your usage patterns demand.
• Use the Filtrete Smart App to create a change countdown by scanning the packaging barcode and selecting 30/60/90 days.

Sizing, Availability, and Brand Trust

Available in multiple MPR ratings (1000, 1200, 1550) and thicknesses (4 in., 4 in. slim, 5 in.). The 1-inch filter is a common choice for many homes, while higher-thickness models offer longer life and stronger filtration. Filtrete promotes a practical approach to maintenance: a dirty filter can slow airflow and force HVAC systems to work harder, potentially impacting energy usage. While expectations vary by home, consistent replacement can contribute to a more comfortable living space.

Filtrete is widely recognized as a leading residential HVAC air filter brand. The No. 1 Recommended HVAC Air Filter Brand claim comes from Ipsos’ 2022 Brand Health Study.
