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., 15x25x1).
  • 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., 14.5x24.5x0.75 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.

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 15"Act 14.5"
Nom 1"Act 0.75
Nom 25"Act 24.5"
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: 14.5x24.5x0.75 in → 15x25x1 nominal.

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.

Understanding MERV Ratings and Why They Matter

When it comes to protecting your family’s health, clean indoor air is just as important as clean drinking water. Yet, many homeowners underestimate the role air filters play in keeping their living spaces healthy.

MERV (Minimum Efficiency Reporting Value) ratings measure how effectively a filter captures airborne particles. They range from 1 to 16—the higher the number, the finer the filtration. A MERV 13 filter is considered a “sweet spot” for homes, capturing up to 98% of microscopic pollutants such as pollen, dust, pet dander, and mold spores.

Think of upgrading to a higher MERV filter like moving from an old flip phone to a modern smartphone—you instantly notice the difference in clarity and comfort. By understanding MERV ratings, you can choose the right protection for your family, enjoy fresher air, and keep your HVAC system running at its best.

Frequently Asked Questions

Is MERV 11 Too High for Residential Use?

Not at all. For most homes, MERV 11 is an excellent choice. It captures pet dander, mold spores, and fine dust without significantly restricting airflow — as long as your HVAC is designed for pleated filters. Always double-check your manufacturer’s recommendations.

Which Is Better: MERV 11 or MERV 13?

  • MERV 11: A solid all-around option for typical households, offering reliable protection from allergens and everyday dust.

  • MERV 13: Offers the highest residential filtration (smoke, bacteria, and even some virus particles), though it can create more airflow resistance.

If your system can handle it, MERV 13 delivers cleaner air. If not, MERV 11 is a safe, balanced alternative.

Is MERV 13 a Good Air Filter?

Yes! A MERV 13 filter is one of the highest ratings recommended for home use. It’s particularly helpful for families dealing with allergies, asthma, or exposure to smoke and urban pollution.

Will MERV 13 Restrict Airflow?

It depends on your HVAC system. Because MERV 13 media is denser, airflow may drop if your unit isn’t designed for higher-MERV filters. A professional can measure pressure drop to confirm compatibility before you upgrade.

Are There Downsides to Using High-MERV Filters?

High-MERV filters are safe and effective when paired with a compatible system, but consider:

  • Possible increased static pressure if airflow is restricted

  • Slightly higher energy use in some setups

  • More frequent replacements (every 2–3 months) since they capture finer particles

Can a MERV 13 Filter Help Reduce COVID-19 Risk?

Yes — MERV 13 filters capture many respiratory droplets and smaller airborne particles, but no filter is 100%. For best protection, combine:

  • MERV 13 (or higher) filtration

  • Good household ventilation

  • Portable HEPA purifiers if needed

Is MERV 8 Too Restrictive for HVAC?

Not at all. MERV 8 filters are very gentle on airflow and serve as a good baseline, protecting your HVAC equipment from dust and lint.

How Often Should a MERV 13 Filter Be Changed?

Because they trap more particles, replace MERV 13 filters every 2–3 months — or sooner if you have pets, allergies, or live in an area with heavy dust or wildfire smoke.

Can Home HVAC Systems Handle MERV 13?

Many modern units can, but some older or undersized blowers may struggle. Check:

  • Your HVAC manual for pressure drop limits

  • The size and condition of your ducts

  • Airflow ratings for your system

When in doubt, an HVAC technician can test compatibility.

What Is the Best MERV Rating for Home Air Filters?

  • Standard homes: MERV 8–11

  • Allergy/asthma households or high pollution: MERV 11–13 (if your system supports it)

  • For the cleanest air without overworking your equipment, MERV 11 is often the sweet spot.

What MERV Ratings Do Hospitals Use?

Hospitals require much tighter filtration:

  • Patient rooms: MERV 14–16

  • Operating rooms: HEPA or MERV 17+

These levels exceed what most home HVAC systems can support.

Does MERV 13 Capture Mold Spores?

Absolutely. A MERV 13 filter effectively traps mold spores, pollen, pet dander, smoke, and other fine particles — delivering cleaner, healthier air throughout your home.
