Things to Know About Filter Sizes

Finger pointing to nominal size

Nominal Size

  • The rounded size printed on your filter or HVAC unit (e.g., 12x15x1).
  • Usually whole numbers to make identifying and ordering easier.
  • A label for compatibility—not the exact measurement.
Finger pointing to actual size

Actual Size

  • The true, trimmed dimensions of the filter (e.g., 11.5x14.5x0.75 inches).
  • Filters are manufactured slightly smaller so they slide into the filter slot without forcing.
  • If you don't know your nominal size, measure your filter to get the actual size, then round up to find the nominal size to search on our site.
Help icon

Why the difference?

  • Nominal sizes simplify shopping and standardize categories.
  • Actual sizes ensure the filter fits properly inside your HVAC's filter rack.

How To Find Your Nominal Size When You Don't Know It

Air Filter Explaining Each Size
Nom 12"Act 11.5"
Nom 1"Act 0.75
Nom 15"Act 14.5"
1

Measure length × width × depth with a tape measure to find the actual size.

2

Round up each dimension to the nearest whole number to get the nominal size. Example: 11.5x14.5x0.75 in → 12x15x1 nominal.

3

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

Pro tips: If your filter is missing or damaged, measure the filter slot opening the same way.

Why Getting the Right Size Matters

  • Too small? Air can bypass the filter, reducing air quality and efficiency.
  • Too big? It won't fit—risking bent frames and airflow issues.
  • Just right? You get maximum performance, better filtration, and cleaner air.

What's a MERV Rating?

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.

Pleated Filters vs. Fiberglass—What's the Difference?

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:

Pleated Filter

Pleated Filters

Efficiency:

High (MERV 8–13) – Traps more particles

Lifespan:

90 days – Long-lasting performance

Air Quality:

Excellent – Cleaner, healthier air

Materials:

Recyclable and durable

Fiberglass Filter

Fiberglass Filters

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.

How Often Should You Change Your Filter?

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:

Calendar Illustration Every 90 days

Every 90 Days

Standard Schedule

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

Calendar Illustration Every 60 days

Every 60 Days

If You Have Pets or Allergies

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.

Calendar Illustration Every 30 days

Every 30 Days

If You Have Respiratory Concerns or Live in Smog/Wildfire Zones

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

Frequently Asked Questions

What does MERV 13 mean, and why is it important?

MERV 13 is a filtration rating that indicates a filter’s ability to capture small airborne particles. It can trap particles as small as 0.3 microns, including allergens, bacteria, smoke, and virus-carriers. It’s recommended for homes needing advanced air quality protection, especially during wildfire season, flu outbreaks, or allergy spikes.

Will a MERV 13 filter reduce airflow in my HVAC system?

Not if your system is compatible. While MERV 13 filters are denser than lower-rated filters, Filterbuy designs them to maintain proper airflow in residential HVAC and furnace systems. Always confirm your system can handle MERV 13 before upgrading.

How often should I replace a 12x15x1 MERV 13 filter?

We recommend replacing it every 3 months under normal conditions. If you have pets, allergies, or high pollution exposure, consider replacing it every 1–2 months for best results.

Is the 12x15x1 filter size a true size or nominal size?

12x15x1 is the nominal size. The actual dimensions are slightly smaller to ensure the filter fits properly in the housing. Filterbuy lists both nominal and exact dimensions for accuracy.

Are Filterbuy MERV 13 filters made in the USA?

Yes. All Filterbuy filters are proudly manufactured in the USA, made-to-order for freshness, and shipped directly from our Alabama facility to ensure quality and fast delivery.
