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., 17.25x23.25x0.75" 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.

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

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: Why This Filter Makes the Difference

Understanding MERV Ratings—and Why They Matter

If you want to protect your family’s health and your HVAC system, understanding MERV ratings is key. MERV—short for Minimum Efficiency Reporting Value—measures how effectively a filter captures airborne particles. Ratings range from 1 to 20, with higher numbers indicating stronger filtration power.

At FilterBuy, we focus on real-world performance. For example, a MERV 13 filter captures microscopic particles such as dust, pollen, mold spores, and pet dander—keeping your indoor air noticeably cleaner and healthier.

Your ideal MERV rating depends on your home’s needs.

Pro Tip: Always confirm your system’s specifications before upgrading—proper compatibility ensures both clean air and smooth system performance.

The Benefits of Choosing MERV 13 Air Filters

A MERV 13 filter does more than catch dust—it actively supports your home’s health and efficiency.

Research from the EPA and CDC confirms that MERV 13 filtration can remove up to 95% of airborne contaminants. That’s the kind of performance our air-obsessed engineers insist on.

How to Choose the Right Filter Size

The right filter size ensures a secure fit, steady airflow, and consistent filtration.

  1. Measure Twice: Check the length, width, and depth of your current filter—usually printed on the frame.

  2. Match Precisely: For example, our 17.25″ × 23.25″ × 1″ filters fit perfectly for optimal efficiency and HVAC protection.

  3. Verify Compatibility: Review your system’s manual or consult a technician if you’re unsure which size or MERV level works best.

A well-fitted filter not only improves air quality but also extends your HVAC system’s lifespan.

Tips to Keep Your Filters Performing Their Best

Consistent maintenance keeps your air cleaner and your system running efficiently.

Routine care helps maintain top-tier filtration and ensures you always breathe your best air.

At FilterBuy, we don’t just repeat lab results—we verify them in real homes across America. Every claim is backed by trusted research and hands-on testing from our U.S. manufacturing team. Here’s what national data and our own field results reveal about MERV 13 performance:

1. MERV 13 Removes More Contaminants

The EPA confirms that upgrading to a MERV 13 (or higher) filter significantly improves your HVAC system’s ability to capture fine particles and airborne viruses. → Source: EPA.gov

In our in-house testing, FilterBuy MERV 13 filters captured up to 98% of particles as small as 0.3 microns—including dust, pollen, and pet dander.

Homeowners also reported easier breathing and fewer allergy symptoms within just weeks of switching to FilterBuy MERV 13 filters.

2. Up to 95% Cleaner Air

According to AirNow (EPA), filters rated MERV 13–16 can remove up to 95% of airborne particles, including smoke, dust, and pet allergens. → Source: AirNow.gov

Field results from FilterBuy homes show less visible dust, smoother airflow, and improved HVAC efficiency after upgrading from MERV 8 → MERV 13.

Our technicians call it “the quiet difference”—cleaner air, quieter systems, and fewer household irritants.

3. Backed by National Health Guidance

The CDC recommends using MERV 13 or higher wherever compatible to reduce airborne contaminants and improve indoor air safety. → Source: CDC.gov

At FilterBuy, we’ve engineered every MERV 13 filter to meet or exceed this national health standard. Each unit is pressure-tested in our U.S. facilities to ensure maximum filtration efficiency without restricting airflow or overstraining your HVAC system.

Frequently Asked Questions

1. What is the best MERV rating for HVAC filters?

For most homes, a MERV 8–13 filter offers the perfect balance of strong filtration, proper airflow, and system efficiency. MERV 13 is ideal for families who want superior protection from dust, allergens, and airborne contaminants.

2. Is MERV 13 too high for residential use?

Not usually. Most modern residential HVAC systems can handle MERV 13 filters with ease—especially when the blower motor is strong and ducts are clean. Always check your system’s manufacturer specifications to confirm compatibility before upgrading.

3. Which is better: MERV 13 or a HEPA filter?

HEPA filters capture even smaller particles, but they’re designed for standalone air purifiers or specialized systems, not standard HVAC units. For typical home systems, MERV 13 is the highest practical and efficient rating available.

4. What is a MERV 13 filter used for?

MERV 13 filters are used anywhere superior air quality is needed—homes, offices, schools, and healthcare settings. They’re especially effective for allergy control and for reducing pet dander, dust, smoke, and bacteria in the air.

5. Which AC filter is best for my home?

For most households, a MERV 11 or MERV 13 pleated filter delivers the best mix of airflow, filtration efficiency, and long-term performance. Both trap a wide range of airborne particles while keeping your system running smoothly.

6. Is MERV 11 too high for residential systems?

No. MERV 11 filters are safe for nearly all residential HVAC setups. They offer a noticeable air quality upgrade over basic filters—without restricting airflow or straining your system.

7. Does MERV 13 catch mold?

Yes. MERV 13 filters capture airborne mold spores effectively, along with bacteria, fine dust, and other microscopic pollutants that contribute to poor indoor air quality.

8. Can my AC handle a MERV 13 filter?

In most cases, yes—especially if your system is newer and well-maintained. If your HVAC system struggles with airflow or is older, consider a MERV 8–11 filter for balanced performance.

9. How long does a MERV 13 air filter last?

Typically 3 months, or up to 6 months in cleaner environments. Homes with pets, allergies, or higher dust levels may need more frequent replacements. For best results, inspect your filter monthly.

10. Will MERV 13 restrict airflow?

Slightly—but a properly sized, high-quality filter and a well-functioning blower motor can handle it easily. Reduced airflow usually means your filter is clogged or undersized, not that your MERV rating is too high.

11. What is the most effective type of air filter?

For central HVAC systems, MERV 13 pleated filters are the most effective choice for capturing fine particles while maintaining airflow. For portable units or air purifiers, true HEPA filters provide the highest particle removal available.

12. Is it good to sleep with a HEPA filter?

Yes. Running a HEPA air purifier while you sleep can help reduce allergens, improve breathing comfort, and promote better rest—especially for those with allergies or asthma.
