Filtrete 16.5x21.5x1 AC Furnace Air Filter | MERV 8 | MPR 700 | 4-Pack – Actual Size 16.19x21.19x0.81 in

Cleaner air for everyday living

Meet the Filtrete 16.5x21.5x1 AC furnace air filter—a 4-pack of 3-month, pleated filters designed to work quietly in your heating and cooling system. With an MPR 700 rating and a MERV 8 performance level, these filters strike a balance between strong particle capture and smooth airflow, helping your HVAC run efficiently while keeping your indoor air circulating more cleanly.

What makes this Filtrete design stand out is its electrostatically charged, pleated media. The media attracts and traps particles like lint, pollen, dust, and pet dander as air passes through, so you may notice less visible debris floating in your living spaces over time. The design is built to help your system breathe easier, contributing to a fresher feel in everyday rooms—from kitchens to bedrooms.

Key benefits at a glance

• Electrostatic media actively attracts and captures common household particles, including pollen and pet dander.
• MPR 700 corresponds to a solid MERV 8 rating, targeting a broad range of particles while maintaining airflow.
• Four-pack provides ready-to-use replacements, helping you stay on schedule without multiple trips to the store.
• Designed for easy installation in standard 1-inch furnace or central AC filters, with true-to-size dimensions for a snug fit.
• Replacement cadence is practical: swap roughly every 90 days to keep your system performing as intended.

Real-life use scenarios

During pollen season, or in homes with pets and active occupants, you may notice filtered air feels crisper and rooms look a touch cleaner as dust settles less on surfaces. The filter’s balance of particle capture and airflow means your furnace or air conditioner can operate without frequent resistance, preserving comfort in everyday routines—from morning showers to late-night movie nights.

Filtrete filters are a practical choice for households that run a tight ship indoors. They’re designed to work within your existing HVAC setup, helping to keep airflow steady while catching a wide spectrum of common irritants.

Usage, reminders, and smart tweaks

Install the filter with airflow arrows pointing in the correct direction. If you’re managing multiple filters or seasonal changes, the 4-pack keeps replacements on hand for prompt swaps. For added convenience, Filtrete offers a Smart App feature that lets you scan the filter barcode and set a replacement countdown (30, 60, or 90 days) with easy reminders when it’s time to change.
