Filtrete 14x14x1 MERV 11 Air Filters — 2-Pack (MPR 1000) Pleated 1" Filters for Allergens & Pets, 90-Day

Filtrete 14x14x1 MPR 1000 (MERV 11) is a 2-pack of pleated 1" AC and furnace filters designed to capture allergens, pet dander and many microparticles while maintaining reliable airflow for up to 90 days.

These Filtrete filters, made by 3M, use the brand’s 3-in-1 filtration technology to trap a broad range of airborne particles — from large debris like lint and pollen to finer microparticles such as smoke and pet dander. Each filter measures 13.68 x 13.68 x 0.81 inches (sold as nominal 14x14x1) and carries a MPR 1000 rating and MERV 11 classification, balancing filtration efficiency with system airflow. They are sold as a two-count pack intended for seasonal maintenance of residential furnaces, air handlers and window AC units, with recommended replacement every 90 days for consistent performance.

How will this filter affect my indoor air quality?

The Filtrete MPR 1000 filter helps lower airborne allergen and dust loads by capturing a wide spectrum of particles as air passes through the pleated media. It is certified asthma and allergy-friendly and designed to reduce visible dust and many smaller particles that contribute to indoor air discomfort.

• Traps large particles: lint, pollen, household dust.
• Captures microparticles: pet dander, smoke, smog (0.3–1.0 micron range targeted by media).
• MPR 1000 / MERV 11 balances capture with airflow for most residential HVAC systems.
• Certified asthma and allergy-friendly for added indoor comfort.

How often should I replace the Filtrete 14x14x1 filter?

• Standard homes: change every 90 days.
• Pet households or higher particle loads: check every 30–60 days.
• Use the Filtrete Smart App to scan packaging barcode and set 30/60/90-day reminders.
• Regular changes help protect HVAC components and preserve airflow.

Will this filter fit my system and affect airflow or energy use?

The filter’s actual dimensions are 13.68 x 13.68 x 0.81 inches, designed to fit nominal 14x14x1 slots in furnaces, air conditioners and many HVAC systems. MERV 11 performance provides good particle removal while maintaining airflow suitable for most residential equipment; always check your system manufacturer’s guidance before upgrading filters.

• Scan barcode on packaging to start a countdown in the app.
• Choose 30-, 60- or 90-day reminder schedules based on household conditions.
• App notifications reduce guesswork and help keep filtration consistent.
