Things to Know About Filter Sizes

Nominal Size
- The rounded size printed on your filter or HVAC unit (e.g., 15x25x1).
- 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., 14.5x24.5x0.75 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: 14.5x24.5x0.75 in → 15x25x1 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.

Understanding MERV Ratings and Their Importance
When it comes to the air you breathe, knowing how filters are rated makes all the difference. MERV (Minimum Efficiency Reporting Value) is the standard that measures how well a filter captures airborne particles. The higher the MERV rating, the smaller the particles it can trap — but balance is key.
For most homes, a MERV 11 filter is a smart choice: it captures fine dust, pollen, and pet dander without straining your HVAC system. Think of it as a shield that helps protect both your family’s lungs and the heart of your home — your HVAC unit. Choose a rating that matches your household’s needs, and you’ll enjoy cleaner, more comfortable air every day.
Advantages of Using MERV 11 Filters
Breathe Easier, Live Better
MERV 11 filters go beyond the basics, capturing stubborn allergens like dust mites, pet dander, and pollen that lower indoor air quality. Customers often notice fewer allergy flare-ups and a fresher feel throughout their home.
Boost System Efficiency
By keeping debris out of your HVAC system, these filters help it run smoothly — reducing wear, improving airflow, and even lowering energy costs. It’s a small swap that delivers big benefits for your comfort and your wallet.
A Simple Step Toward a Healthier Home
Upgrading to MERV 11 is one of the easiest ways to create a cleaner, more welcoming living space for the people (and pets!) you love.
How to Choose the Right Air Filter for Your Home
Selecting the right filter doesn’t have to be complicated. Here’s how to make a confident choice:
Know Your Options: Understand the basics — pleated, HEPA, or fiberglass and which works best for your needs.
Consider Your Air Quality: Allergies, pets, or dust-prone environments may require a higher MERV level.
Measure Accurately: Confirm the exact size your system needs (for example, 15x25x1) to ensure a perfect fit.
Stay on Schedule: Replace filters every 1–3 months, depending on usage, for steady protection and performance.
Balance Cost & Quality: Investing a little more in a well-made filter can save money (and headaches) in the long run.

Frequently Asked Questions About Air Filters
Is MERV 11 Too High for Residential Use?
For most homes, MERV 11 is perfectly safe — and a smart choice if you want to capture pet dander, mold spores, and fine dust. The key is knowing your system: older or low-powered units may not handle higher resistance as easily. When in doubt, check your HVAC manual or ask a professional to confirm compatibility.
Which Is Better: MERV 8, 11, or 13?
MERV 8 → A solid, budget-friendly option for dust, pollen, and lint.
MERV 11 → The sweet spot for most families, trapping smaller particles like smoke and pet dander — ideal for allergy sufferers.
MERV 13 → Designed for ultra-fine particles (bacteria, smoke, some viruses). Best for medical or high-sensitivity spaces rather than standard homes.
Is There a Downside to Higher MERV Filters?
Yes airflow resistance. Filters above MERV 13 can strain a residential system if it isn’t designed for them. Restricted airflow may reduce efficiency, raise energy bills, and even damage the blower motor over time.
Is the MERV 11 Rating Good?
Absolutely. MERV 11 is an excellent mid-tier rating that improves indoor air quality without overloading most HVAC systems — making it one of our most recommended options.
How Long Does a MERV 11 Air Filter Last?
Typically up to 90 days, but usage matters:
Homes with pets may need a change every 30–60 days.
Renovations or nearby construction can shorten its lifespan.
Heavy pollen or wildfire smoke may require more frequent checks.
Inspect monthly and replace when the filter looks gray or clogged.
What’s the Best MERV Rating for a Home Air Filter?
Average homes → MERV 8–11
Allergy/asthma concerns → MERV 11–13 (if your system supports it)
Hospitals or clean rooms → MERV 14+ (not typical for residential systems)
What Brand of Air Filter Is Best?
Look for brands with sturdy frames, consistent pleats, and published MERV data:
FilterBuy – American-made with custom sizes and rigorous quality control
Honeywell
3M Filtrete
Choosing a reliable brand ensures steady performance and peace of mind.
What’s the Difference Between Cheap and Premium Filters?
Budget filters: Thin fiberglass (MERV 2–4), only catch large debris.
Quality filters: Pleated, electrostatically charged, with stronger frames and higher MERV (8–13). They last longer, protect your HVAC system, and noticeably improve air quality.
How Often Should I Change My Air Filter?
Standard pleated filters (MERV 8–11): Every 90 days
Homes with pets, smokers, or heavy dust: Every 30–60 days
Vacation or rarely used homes: Up to 6 months
How Can I Tell If a Filter Needs Replacing?
Visible dirt or a gray coating
Weak airflow at vents
HVAC runs longer or cycles more often
Allergy symptoms start flaring up
How Much Do HVAC Filters Cost?
Basic fiberglass (MERV 2–4): $5–$10
Pleated (MERV 8–11): $10–$25
High-end (MERV 13): $20–$40+Buying in bulk packs can cut the cost per filter.
Does the Air Filter Affect My AC?
Yes! A clean filter keeps airflow strong, helps your AC cool efficiently, and prevents frozen coils. A clogged filter forces your system to work harder — driving up energy bills and risking expensive repairs.
