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., 18x30x1).
  • 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 3/4" x 29 3/4" x 3/4 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

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

What makes Filterbuy’s Odor Eliminator filters different from standard air filters?

Unlike standard filters that only trap dust and debris, our Odor Eliminator filters feature an activated carbon layer designed to neutralize common household odors like pet smells, cooking fumes, and smoke. They're also pleated for better airflow and longer life.

How often should I replace my 18x30x1 Odor Eliminator filter?

We recommend replacing your filter every 90 days for typical use. However, homes with pets, smokers, or allergy-sensitive individuals may benefit from more frequent changes—every 60 days or even monthly.

Will this filter fit my HVAC system or furnace?

Yes, if your system requires an 18x30x1 filter. Always measure your existing filter or check the model specifications before ordering to ensure a proper fit.

Can this filter help with allergies or asthma?

Yes. While it's designed primarily for odor removal, the pleated MERV-rated construction also captures pollen, dander, and other airborne irritants that can trigger allergies or respiratory issues.

Is this filter made in the USA?

Absolutely. All Filterbuy air filters are proudly manufactured in the USA using high-quality, durable materials to ensure dependable performance and fast shipping.
