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., 17.25x23.25x1).
  • 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., 17.25x23.25x1" 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.

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:

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

Top Takeaways

Understanding MERV Ratings and Their Importance

When it comes to protecting your home’s air, understanding MERV ratings is the first step toward breathing cleaner, healthier air. MERV stands for Minimum Efficiency Reporting Value—a standardized scale that measures how effectively an air filter captures particles of different sizes.

The higher the MERV rating, the finer the filtration. But higher isn’t always better for every home. A MERV 8 filter strikes the perfect balance — powerful enough to trap up to 90% of dust, pollen, and household irritants while maintaining strong airflow to keep your HVAC system running efficiently.

At FilterBuy, we’ve tested countless materials and configurations in our own manufacturing facility. The result: filters that not only meet industry standards but exceed them in real-world performance. Choosing the right MERV rating means fewer allergens, less strain on your system, and a healthier environment for your family.

Benefits of Using MERV 8 Air Filters

A MERV 8 filter is the everyday hero of home air quality — strong enough to capture the most common airborne contaminants without restricting airflow. Here’s how it makes a difference:

Every FilterBuy filter is American-made, precision-cut, and quality-tested in our Alabama facility, so you can trust that it performs exactly as promised.

How to Choose the Right Air Filter for Your Home

Frequently Asked Questions

Is MERV 8 a good AC filter?

Yes. A MERV 8 filter is an excellent choice for most homes. It effectively captures up to 90% of common airborne particles like dust, pollen, and pet dander — all while maintaining strong airflow. It’s the perfect balance between clean air and efficient system performance.

Which MERV rating is best for my HVAC system?

For most residential systems, MERV 8–11 offers the ideal balance of airflow and filtration. If you have allergies, pets, or higher air quality needs, a MERV 11 or 13 may be best — as long as your system is rated for higher resistance filters.

How long does a MERV 8 filter last?

We recommend replacing your filter every 1–3 months, depending on your home’s conditions. Homes with pets, high dust, or frequent HVAC use may need more frequent changes. Check monthly and replace if the filter looks dirty or airflow feels reduced.

Can a MERV 8 filter improve air quality?

Absolutely. A MERV 8 filter captures the majority of visible dust and larger airborne particles, helping reduce allergens and improve indoor comfort. You’ll notice less dust on surfaces — and cleaner, fresher air for your family to breathe.

Can a filter with too high of a MERV rating cause problems?

Yes, if your system isn’t built for it. Very high MERV filters (13–16+) can restrict airflow in systems not designed for dense filtration. This may lead to higher energy use or motor strain. Always check your HVAC specifications or ask a FilterBuy expert before upgrading.

Which AC filter is best overall?

The best filter is one that fits your system’s specifications and your lifestyle.

Is MERV 8 too restrictive for an HVAC system?

Not at all. MERV 8 filters are designed to maintain excellent airflow while trapping harmful particles. It’s a safe, efficient choice for nearly all standard residential systems.

Will a higher MERV filter save me money?

Not immediately — but over time, yes. Higher-quality filters keep your HVAC system cleaner, helping it run more efficiently and last longer. This can reduce maintenance costs and extend your system’s lifespan.

What is the pressure drop on a MERV 8 filter?

Typically between 0.1–0.3 inches of water column (in. w.c.), depending on your system and airflow. That’s considered low resistance, which means your system can breathe easily while filtering effectively.

What happens if I don’t change my HVAC filter?

A dirty filter restricts airflow — forcing your system to work harder. This leads to higher energy bills, reduced cooling, and even potential damage to your unit. Regular replacements are one of the easiest ways to protect your investment and your air quality.

Do more expensive furnace filters last longer?

Generally, yes. Premium filters often use denser, pleated materials that hold more particles and maintain efficiency longer. Even so, they should still be replaced every 2–3 months for peak performance.

Will a new filter make my AC colder?

Indirectly, yes. A clean filter improves airflow, allowing the system’s coils to cool air more efficiently. You’ll experience stronger airflow, better cooling, and improved comfort throughout your home.
