Round up each dimension to the nearest whole number to get the nominal size. Example: 11.5x14.5x1" in → 12x15x1 nominal.

Search by nominal size on our site for the best fit.

If the filter you buy doesn't fit, we'll send you a better size.
MERV stands for Minimum Efficiency Reporting Value—but don't let the technical name fool you. It's just a way to rate how well an air filter traps stuff like dust, pollen, pet dander, and smoke. The higher the MERV number, the more particles it catches—and the cleaner your air will be.

We build every Filterbuy filter to deliver reliable 90-day performance—thanks to smart design and premium materials that do the heavy lifting. Here's what makes the difference:
More pleats = more surface area to capture dust and debris, keeping your air cleaner longer.
Pleats are magnetized to attract and trap microscopic particles—like pet dander, pollen, and smoke.
Engineered to resist warping in extreme temperatures and high humidity.

A layer of metal reinforcement keeps pleats evenly spaced and structurally sound—no sagging, even at high airflow.
Assembled with care. Built to perform. Ships fast, free, and reliably from our U.S. facilities.

Not all air filters are created equal. Pleated filters don't just last longer—they actually clean your air better. Here's how they stack up:

Efficiency:
High (MERV 8–13) – Traps more particles
Lifespan:
90 days – Long-lasting performance
Air Quality:
Excellent – Cleaner, healthier air
Materials:
Recyclable and durable

Efficiency:
Low (MERV 4 or less) – Misses small stuff
Lifespan:
30 days or less – Replace often
Air Quality:
Minimal – Basic protection only
Materials:
Thin, flimsy, and not recyclable
Pleated filters are a no-brainer—more protection, less hassle, and better air for your home.
Changing your filter on time keeps your HVAC system running efficiently—and helps protect your lungs from dust, allergens, and airborne irritants. Here's how often to swap it out based on your needs:

For most homes without pets or special air quality concerns. Great for general upkeep and energy efficiency.

Shedding fur, dander, and allergy triggers can build up fast. Changing your filter every two months helps keep the air fresher and symptoms at bay.

For households affected by smoke, pollution, or respiratory conditions, monthly changes ensure maximum protection.

Filterbuy's 12x15x1 MERV 11 pleated air filter is the best product for those who want advanced indoor air quality without losing HVAC efficiency. This filter is highly efficient in the range of 95% of airborne particles—which mainly are dust mites, pet dander, mold spores, pollen, and smoke—that it is able to remove from the air, and thus the filter creates a very powerful barrier to common allergens and irritants.
Made in the United States of America using a synthetic material that is electrically charged, our filters are designed in such a way that they can catch the maximum number of particles with minimum airflow resistance, thus aiding your system in running efficiently, along with having cleaner air. The wood frame of industrial beverage grade will not warp, causing stiffness, and thus it is highly durable and long-lasting, with performance continuing during the 3-month lifespan.
If you are a person who changes a filter or upgrades it for better protection, then you can choose this MERV 11 option, which is perfect for households with pets, allergy sufferers, or anyone looking for a healthier home environment. Filterbuy’s promise of fast, free delivery and quality support makes it an intelligent option for a long-lasting, reliable filter.
