What this filter can help with

• Small particle filtration: testing indicates the filter can capture up to 50 percent of particles in the 0.3 to 1 micron range as air passes through.
• Dust, lint, pollen, and pet dander are trapped, helping reduce visible dust buildup and improve air feel between cleanings.
• Common indoor pollutants such as smoke and smog traveling through ducts may be captured before entering living spaces.

Technology and design

Filtrete 3-in-1 technology uses a micro-fiber network to attract and trap particles, balancing strong filtration with airflow. The design is intended to work with various brands and models, including Lennox and Honeywell media air cleaners.

• Asthma and allergy friendly certification highlights a focus on reducing irritants in household air.
• Smart reminders via the Filtrete app help you track replacement dates with options for 90, 180, or 365 days.
• Designed for year-long replacement cycles when used in appropriately sized 4-inch slots.

Fit, maintenance, and setup

The exact dimensions of the filter are 15.88 by 24.56 by 4.31 inches, making it suitable for systems that require a 4-inch-thick filter. The 4-pack format offers multiple replacements to keep filtration consistent throughout the year.
