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., 15x28x1).
  • 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., 15x28x1 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.

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

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

Round up each dimension to the nearest whole number to get the nominal size. Example: 15x28x1 in → 15x28x1 nominal.

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

Is MERV 8 OK for residential use?

Absolutely. MERV 8 filters are an excellent choice for most homes. They capture everyday particles—like dust, lint, pollen, mold spores, and pet dander—without overworking your HVAC system. If you don’t have serious allergy or smoke concerns, MERV 8 delivers solid protection and airflow.

Which is better: MERV 8, 11, or 13?

How often should I replace a MERV 8 filter?

Plan to change it about every 90 days. Swap it sooner (every 30–60 days) if:

What is the best MERV rating for home air filters?

For most households, MERV 8–11 offers the best balance of filtration and airflow. If you need hospital-grade protection and your system supports it, MERV 13 is a strong choice. Ultra-high ratings (MERV 14–16) are generally reserved for commercial or healthcare environments.

Are expensive MERV filters worth it?

Sometimes. Higher-priced filters often carry higher MERV ratings or special coatings. If you’re fighting smoke, fine allergens, or viruses, that extra efficiency may be worthwhile. For everyday dust and pollen, a quality MERV 8 or 11 filter usually delivers the best value.

What MERV rating do hospitals use?

Hospitals typically use MERV 13–16 filters, and some areas—like operating rooms—rely on HEPA filters, which capture 99.97% of particles ≥0.3 microns.

Is MERV or HEPA better?

HEPA provides superior filtration but isn’t always compatible with standard HVAC systems unless special fans are installed.

What type of air filter is best for HVAC systems?

A pleated filter with a MERV 8–11 rating is ideal for most residential HVAC setups. It balances airflow, efficiency, and equipment protection.

What is the pressure drop on a MERV 8 filter?

Pressure drop varies by brand and size, but most MERV 8 filters show an initial resistance of about 0.15–0.25 in. w.c. at 300 feet per minute airflow—low enough for most systems.

Are all MERV 8 pleated filters the same?

Not at all. Quality matters! Look for:

Cheaper options may have weaker construction or lower actual efficiency.

What if filter pressure is too high?

High pressure means your system is struggling for airflow, which can:

Switch to a lower-MERV filter or choose a deeper filter (4–5") to maintain proper airflow.

Does a higher MERV rating reduce airflow?

Yes. Higher MERV ratings use denser filter media, which can restrict airflow if your HVAC system isn’t designed for it. Always review your system’s specifications before upgrading.
