Things to Know About Filter Sizes

Nominal Size
- The rounded size printed on your filter or HVAC unit (e.g., 12x30x1).
- 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., 11.88x29.88x0.75 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: 11.88x29.88x0.75 in → 12x30x1 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.

Frequently Asked Questions
What does MERV 8 mean in a 12x30x1 air filter?
MERV stands for Minimum Efficiency Reporting Value, a rating system developed by ASHRAE. A MERV 8 filter captures approximately 70% of particles in the 3.0–10.0 micron range, including common allergens like dust, pollen, mold spores, and pet dander—ideal for most residential homes.
How often should I replace my 12x30x1 MERV 8 pleated air filter?
We recommend replacing your MERV 8 filter every 90 days for optimal performance. However, you may need to change it more frequently (every 30–60 days) if you have pets, allergies, or live in a high-dust area.
Is a MERV 8 filter safe for my HVAC system?
Yes. MERV 8 is widely considered the ideal balance between filtration and airflow. It offers effective particle capture without putting unnecessary strain on standard residential HVAC systems, unlike higher MERV-rated filters that may reduce airflow.
What are the benefits of pleated filters vs. fiberglass filters?
Pleated filters have a larger surface area, allowing them to capture more particles and last longer than flat fiberglass filters. They also offer better structural integrity and don’t collapse or degrade as easily under airflow pressure.
