Filtrete 16x20x1 AC Furnace Filter — MERV 14, MPR 2500, 4-Pack

Cleaner air starts with a smart, reliable filter

Filtrete’s 16x20x1 AC furnace filter combines exclusive 3-in-1 technology with a high MPR 2500 score and a MERV 14 standard. This multi-layer design is built to pull in and trap a wide range of particles while still allowing cleaner air to flow through your HVAC system. In real-world use, this means your home’s air can feel crisper and the space around you may look and smell less dusty or smoky. The 4-pack offers consistent availability, so replacements stay simple across seasons without interrupting your comfort.

Key specs and how they translate to daily use

• Three-in-1 filtration that pulls in and traps a broad spectrum of particles, from large debris to ultrafine particles
• Exact dimensions: 15.63 x 19.63 x 0.78 inches (slightly different from nominal size) for a snug fit in many 16x20x1 housings
• MPR 2500 and MERV 14 ratings support versatile filtration performance, targeting a wide range of indoor pollutants
• Designed for use with furnaces, air conditioners, or whole HVAC systems for flexible installation

The filter is pleated and 1 inch thick, a balance of filtration efficiency and airflow. Its design helps maintain steady airflow through your system, which can support consistent temperature distribution and potentially reduce energy strain on your equipment. In addition to trapping larger irritants like lint and pollen, it targets countless microparticles that can circulate in busy living spaces.

Real-world benefits you might notice

• Better airflow in rooms with high activity, pets, or frequent cooking
• Reduction in visible dust buildup on surfaces between cleaning sessions
• Potential improvement in air feel during allergy seasons thanks to broader particle capture, including ultrafine particles and aerosols

As noted in the product data, the filter can capture a significant portion of airborne particles, including up to 90% of virus-containing particles in certain conditions (1). This data point is provided for context and should be interpreted as part of a broader air filtration approach, not a guarantee of health outcomes. For ongoing maintenance, use the Filtrete Smart App to set reminders for 30, 60, or 90 days between filter changes.

Care and replacement guidance

• Replace at least every 90 days for optimal performance in typical homes
• In households with pets, smokers, or high use, consider more frequent changes
• Keep a spare in the four-pack for easy, on-time replacements

Filtrete is a trusted name in HVAC filtration, and this 4-pack makes it convenient to maintain a schedule that helps keep your living space feeling fresh and comfortable.
