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: 15.5x31.5x1.75 in → 16x32x2 nominal.
Search by nominal size on our site for the best fit.
If the filter you buy doesn't fit, we'll send you a better size.
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.

We build every Filterbuy filter to deliver reliable 90-day performance—thanks to smart design and premium materials that do the heavy lifting. Here's what makes the difference:
More pleats = more surface area to capture dust and debris, keeping your air cleaner longer.
Pleats are magnetized to attract and trap microscopic particles—like pet dander, pollen, and smoke.
Engineered to resist warping in extreme temperatures and high humidity.
A layer of metal reinforcement keeps pleats evenly spaced and structurally sound—no sagging, even at high airflow.
Assembled with care. Built to perform. Ships fast, free, and reliably from our U.S. facilities.

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:
Efficiency:
High (MERV 8–13) – Traps more particles
Lifespan:
90 days – Long-lasting performance
Air Quality:
Excellent – Cleaner, healthier air
Materials:
Recyclable and durable
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.
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:
For most homes without pets or special air quality concerns. Great for general upkeep and energy efficiency.
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.
For households affected by smoke, pollution, or respiratory conditions, monthly changes ensure maximum protection.

A 16x32x2 MERV 11 air filter is a two-inch pleated replacement filter for your furnace, air conditioner, or heat pump. MERV 11 Captures 95% of Airborne Particles, and it’s our Superior tier, made for allergy sufferers. You order by the nominal size, 16x32x2. Check your HVAC manual to confirm the tier your system takes.
Order by the nominal size. 16x32x2 is the name you shop by. The cut is slightly smaller by design, and that clearance is what lets the filter slide in.
MERV 11 Captures 95% of Airborne Particles. It’s the Superior tier, comparable to MPR 1000–1200 and FPR 7.
Check your HVAC manual before you pick a tier. It’s a quick fit check, the same as confirming your size.
Filterbuy is a manufacturer, not a reseller. We cut, pleat, and frame every 16x32x2 to order in our own US plants.
A 16x32x2 MERV 11 air filter is a two-inch-deep pleated filter that sits in the return of your furnace, air conditioner, or heat pump. MERV stands for Minimum Efficiency Reporting Value, which is the industry scale for how much airborne particulate a filter catches. The higher the number, the more it captures.
MERV 11 Captures 95% of Airborne Particles. It’s the tier we make for allergy sufferers, and it’s the one to pick if you’ve got pets or pollen coming in.
Filterbuy makes this size because customers kept asking for it. The long-rectangle 16x32 footprint is uncommon enough that most stores skip it, so we stock 16x32x2 air filters in MERV 8, 11, and 13 as a standard catalog size.
Finding your size usually takes about ten seconds, because it’s printed right on the filter you already have.
Read the size off your old filter. Most frames print it along one edge.
If the slot is empty, measure the opening with a tape measure: length, width, then depth.
Round each measurement up to the nearest whole inch. That gives you the nominal size.
Order by the nominal size, 16x32x2. Our cut runs slightly smaller, and that clearance is what lets the filter slide in without forcing. If you don’t see your size on the site, we cut custom air filters to the eighth of an inch. Order the wrong one and our free exchange has you covered.
Filterbuy makes the 16x32x2 in three tiers, and each one has a job.
MPR and FPR are third-party rating systems developed by other companies, shown here for comparison only. Check your HVAC manual to confirm the tier your system takes.
MERV 8 is the standard choice for most homes. MERV 11 is our tier for allergy sufferers, and it’s the one to pick if you’ve got pets or pollen. MERV 13 is our Optimal tier and the one to pick for smoke. If odors are what you’re dealing with, our Odor Eliminator carbon filter handles those instead.
Before you settle on a tier, check your HVAC manual to confirm what your system takes. It’s a quick fit check, the same as confirming your size. You can compare all three in our guide to choosing a MERV rating.

Here’s something worth knowing if you’re comparing depths. Our 16x32x1 carries 14 pleats per foot. This 16x32x2 carries 10. Fewer pleats sounds like less filter, but each pleat here is far deeper, so the two-inch holds more media overall. Pleat count isn’t the number to shop on. Use one filter per slot, too: two one-inch filters stacked together don’t add up to a two-inch.
Electrostatically charged pleated media in a beverage board frame that resists warping in attic and crawlspace heat.

Pick your pack by how often you change the filter. At a 90-day interval, one slot goes through four filters a year. At 60 days, it’s six.
Based on one filter slot. If your home has two returns that take 16x32x2, double the quantities above.

These findings describe the air in American homes. They don’t describe what any filter does, but they’re useful context when you’re deciding how much filtration you want.
You breathe indoor air about 90% of the time. Indoor levels of some pollutants run 2 to 5 times outdoor levels, according to the U.S. Environmental Protection Agency.
More than 90% of U.S. homes carry three or more allergens. NIEHS researchers, part of NIH, measured eight allergens across nearly 7,000 bedrooms. Pets and pests drove the highest readings.
152.3 million Americans live where the air fails. That’s 44% of the country, according to the American Lung Association’s State of the Air 2026 report.
Source links appear in the body copy above. These figures describe air quality generally. They are not a measure of what any filter does.
Every 90 days in a typical home. If you’ve got pets or allergy sufferers, every 60 days keeps it fresher. Hold the filter up to a light. If light doesn’t pass through the pleats, it’s time.
MERV 8 is the standard choice for most homes, MERV 11 is our tier for allergy sufferers, and MERV 13 is the one for smoke. Check your HVAC manual to confirm what your system takes.
Yes. We cut, pleat, and frame every one to order in our own US plants.
No, it won’t fit. If your slot is an inch deep, order a 16x32x1 MERV 11 filter instead. Don’t stack two one-inch filters to fill a two-inch slot either.
Filterbuy stocks 600+ standard sizes, so start by searching your nominal size. If it isn’t listed, we cut custom filters to the eighth of an inch.
