Things to Know About Filter Sizes
Nominal Size
- The rounded size printed on your filter or HVAC unit (e.g., 24x24x1).
- Usually whole numbers to make identifying and ordering easier.
- A label for compatibility—not the exact measurement.
Actual Size
- The true, trimmed dimensions of the filter (e.g., 23.38x23.38x0.75 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.
How To Find Your Nominal Size When You Don't Know It
Measure length × width × depth with a tape measure to find the actual size.
Round up each dimension to the nearest whole number to get the nominal size. Example: 23.38x23.38x0.75 in → 24x24x1 nominal.
Search by nominal size on our site for the best fit.
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.
Free Exchange Policy
If the filter you buy doesn't fit, we'll send you a better size.
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 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 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 ScheduleFor most homes without pets or special air quality concerns. Great for general upkeep and energy efficiency.
Every 60 Days
If You Have Pets or AllergiesShedding fur, dander, and allergy triggers can build up fast. Changing your filter every two months helps keep the air fresher and symptoms at bay.
Every 30 Days
If You Have Respiratory Concerns or Live in Smog/Wildfire ZonesFor households affected by smoke, pollution, or respiratory conditions, monthly changes ensure maximum protection.
