Filtrete 20x25x2 AC Furnace Air Filter – MERV 11, MPR 1000, Allergen Defense, 4-Pack (Actual Size 19.5 x 24.5 x 1.75 in)

Cleaner, fresher air for your home

The Filtrete 20x25x2 air filter combines a high MPR 1000 with a MERV 11 rating to help reduce a broad range of particles while maintaining steady airflow through your HVAC system. As air passes through the pleated media, it can attract and trap common household irritants such as pet dander, smoke and smog, along with everyday dust.

Designed with exclusive Filtrete 3-in-1 technology, this filter actively starts to pull in, trap, and hold particles, letting cleaner air circulate back into living spaces. The unit’s actual size is 19.5 x 24.5 x 1.75 inches, which is slightly different from the nominal 20x25x2 dimension but still compatible with many standard filter slots.

What makes Filtrete 3-in-1 technology effective

• Balanced filtration and airflow: high-efficiency particle capture without overly restricting air movement
• Wide particle range: captures both microscopic irritants and larger dust and pollen
• Smart design: pleated media helps maximize surface area for filtration

In everyday use, you may notice a perceptible difference in air quality, particularly in rooms that see heavy activity, pet traffic, or cooking emissions. The filter is certified asthma and allergy-friendly and is produced with at least 50% recycled content, according to third-party verification.

Usage, maintenance, and convenience

• Versatile: suitable for furnaces, air conditioners, or full HVAC systems
• Maintenance: change every 90 days for optimum performance
• Smart reminders: Filtrete App (iOS/Android) helps you schedule 30-, 60-, or 90-day change notices
