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., 17.25x26x1).
  • 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., 17.25x26x1" 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.

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:

Every 90 Days

Standard Schedule

How to Choose the Right Air Filter Size

Selecting the correct air filter size is essential for maintaining HVAC efficiency and ensuring optimal air quality.

Common filter types, including pleated, fiberglass, and HEPA, each offer varying levels of efficiency.

Frequently Asked Questions

What is the best MERV rating for HVAC filters?

The best MERV rating for most residential applications is between 8 and 13. MERV 8 to 13 filters offer excellent filtration for dust, pollen, and other common allergens while maintaining optimal airflow for your HVAC system.

Is MERV 13 too high for residential use?

No, MERV 13 is not too high for residential use. It offers top-tier filtration for dust, pollen, pet dander, and other allergens without significantly restricting airflow, making it a great choice for homes that prioritize air quality.

What is the MERV 13 rating for air filters?

MERV 13 filters capture particles as small as 0.3 microns, including dust, pollen, mold spores, and pet dander. These filters provide high-efficiency filtration, especially beneficial for households with allergy sufferers or individuals with sensitivities.

Can I use MERV 13 in my HVAC system?

Yes, MERV 13 filters are compatible with most residential HVAC systems. Just be sure your system can handle the slight airflow restrictions, especially in older units. If you're unsure, consult your system's manufacturer for guidance.

Which AC filter is best?

For most residential AC systems, MERV 8 to 13 filters are ideal. MERV 13 filters provide the highest level of filtration without sacrificing airflow, making them a solid choice for homes needing superior air quality.

Is MERV 11 too high for residential use?

No, MERV 11 is a great choice for residential use. It offers strong filtration, particularly for allergy and respiratory concerns, without causing significant strain on your HVAC system.

Does MERV 13 catch mold?

Yes, MERV 13 filters are effective at capturing mold spores, helping to improve indoor air quality, especially in homes with mold issues or high humidity.

How long do MERV 13 air filters last?

MERV 13 filters typically last between 1 and 3 months, depending on the air quality and how much the HVAC system is used. Regular replacement ensures optimal efficiency and air quality.

Will MERV 13 restrict airflow?

While MERV 13 filters are highly efficient, they may slightly reduce airflow compared to lower-rated filters. However, most modern HVAC systems are designed to handle this level of filtration without significant issues.

Which Filtrete filter is MERV 13?

Filtrete offers several MERV 13 filters, including their Healthy Living series, which are designed to capture allergens and improve indoor air quality, making them a great option for households with sensitive individuals.

Can too high of a MERV rating cause problems?

Yes, filters with very high MERV ratings (above 13) can restrict airflow, especially in older or less powerful HVAC systems. This can reduce system efficiency and potentially cause strain. Always check your system's compatibility before choosing a filter with a high MERV rating.

Can a MERV 13 filter remove odors?

While MERV 13 filters capture larger particles that may contribute to odors, they are not designed to remove smells. For odor removal, filters with activated carbon or specialized filtration systems may be more effective.
