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., 17.25x29.25x1).
  • 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., 17.25x29.25x1" 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.

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 a Good AC Filter?

Yes, MERV 8 is an excellent choice for standard residential HVAC systems. It efficiently captures dust, pollen, pet dander, and other common allergens, improving air quality while maintaining good airflow. It’s a perfect option for most households, offering a balance of filtration and efficiency.

Which MERV Rating is Best for an HVAC System?

MERV 8 to MERV 11 filters are generally the best choice for residential HVAC systems. They strike a perfect balance between improving air quality and ensuring optimal airflow efficiency.

Which is Better, MERV 8, 11, or 13?

MERV 11 and MERV 13 offer superior filtration compared to MERV 8, capturing smaller particles like mold spores and bacteria. However, they can create more airflow resistance, which might not be ideal for all HVAC systems, especially if maintaining airflow is a priority.

Can MERV 8 Improve Air Quality?

Yes, MERV 8 filters are great at improving air quality by capturing dust, pet dander, pollen, and some mold spores. This makes MERV 8 a solid choice for most homes, providing cleaner air for you and your family.

How Long Will a MERV 8 Filter Last?

Typically, a MERV 8 filter lasts about 3 months, though this can vary based on factors like air quality, the number of people or pets in the home, and how often the HVAC system is used.

Can a High MERV Rating Cause Problems?

Yes, filters with a very high MERV rating (such as MERV 13+) can sometimes cause airflow issues, putting strain on your HVAC system. This can reduce the system’s efficiency and lifespan, so it's important to choose the right MERV for your needs.

Is MERV 8 Too Restrictive for HVAC Systems?

No, MERV 8 is not too restrictive for most residential HVAC systems. It offers excellent filtration while maintaining good airflow, making it an ideal choice for most homes.

Which is Better, MERV 8 or MERV 10?

MERV 10 offers slightly better filtration than MERV 8 by capturing smaller particles, but it may cause a bit more airflow resistance. Both are great options for general household use, with MERV 10 being a slightly more efficient choice.

What is the Pressure Drop on a MERV 8 Filter?

The pressure drop on a MERV 8 filter is typically low, around 0.1 to 0.2 inches of water column, ensuring minimal airflow restriction and maintaining HVAC system efficiency.

What is the Best Brand for Furnace Filters?

Reliable and trusted brands like FilterBuy, 3M Filtrete, and Honeywell are known for their quality and performance in furnace filters, offering excellent filtration options for homeowners.

Which is Better, HEPA or MERV?

HEPA filters are more efficient than MERV filters at capturing very small particles (0.3 microns or larger), but they are generally not used in HVAC systems due to their higher resistance to airflow. MERV filters, however, are a great choice for residential HVAC systems.

Which is Better, Pleated or Non-Pleated Air Filters?

Pleated filters are typically better than non-pleated filters. Their larger surface area allows for better filtration and a longer lifespan, making them a more efficient and cost-effective option for most homes.
