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 1/2" x 19 1/2" x 3/4" in → 16x20x1 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.

At Filterbuy, we don’t just sell 16x20x1 MERV 11 HVAC and furnace filters—we manufacture them with the same standards we use in our own homes. Based on decades of hands-on experience and customer feedback, we’ve fine-tuned every layer of our filters to capture over 90% of airborne particles like dust, pollen, and pet dander, without restricting airflow or stressing your system. Unlike mass-produced alternatives, our filters are made in the USA, rigorously quality-tested, and shipped directly from our family-owned facility for peak performance you can feel. If you care about long-lasting protection and real indoor air quality, this is where your search ends.
Filterbuy's 16x20x1 MERV 11 air filters are manufactured in the United States and engineered to capture the airborne particles that matter most to your family's health — including dust, pollen, mold spores, pet dander, and fine lint. After manufacturing filters for over a decade and serving more than two million households, we recommend MERV 11 for most homes because it delivers meaningful filtration without restricting airflow to standard residential HVAC systems.
Here's what sets Filterbuy's 16x20x1 MERV 11 filter apart:
Superior particle capture. Traps up to 85% of particles between 3.0–10.0 microns, including common household allergens and fine debris your HVAC would otherwise recirculate.
American-made quality. Every filter is manufactured domestically with electrostatically charged media for consistent performance from the first day to the last.
Exact-fit sizing. Our 16x20x1 filters are cut to true dimensions, ensuring a proper seal with no bypass gaps that allow unfiltered air to sneak past the frame.
Flexible replacement schedules. Most homes should replace every 60–90 days; homes with pets or allergy sufferers benefit from monthly changes.
Subscription savings available. Auto-delivery keeps your filter schedule on track so your HVAC system is never running on a clogged, overworked filter.
Filterbuy's 16x20x1 MERV 11 filters are available in single packs and multi-packs at filterbuy.com.
MERV 11 = Best Balance Traps fine particles without blocking airflow.
Made in the USA Built, tested, and trusted by Filterbuy.
Indoor Air = 2–5x Dirtier EPA data shows indoor air is more polluted than outside.
Saves Energy Clean filters can cut HVAC energy use by up to 15%.
We Use What We Sell Designed for our homes—built for yours.
Talking about healthy indoor air, definitely not all air filters are the same. Our MERV 11 16x20x1 HVAC and furnace filters are made of a special material that can go deep and catch tiny airborne particles that are invisible to the naked eye—dust, mold spores, pet dander, and pollen. These filters are an ideal choice to upgrade if you are allergy-sensitive, if you have pets, or if your house is a high-traffic one.
The key difference that makes Filterbuy unique is our vertically integrated production nature: thus, we design, produce, and ship every filter directly from our U.S.-based facility, which guarantees the highest quality control and fastest delivery. The pleated design greatly enlarges the surface area for life span and more efficient filtration, while keeping the system free from resistance and operating at maximum efficiency.
If you are the one replacing your filters seasonally, or you are buying in bulk for a better price, Filterbuy facilitates hassle-free delivery of high-performance MERV 11 filters right at your door along with our promise of air quality, durability, and customer satisfaction.

“We design our 16x20x1 MERV 11 filters with the same care we put into the ones we use in our own homes—because we know how much clean air matters. After decades of testing materials and studying airflow dynamics, we’ve learned that real filtration performance comes down to balance: capturing fine particles without straining your HVAC system. That’s the standard we build into every filter we ship.”
At Filterbuy, we’ve seen how poor filtration affects homes and HVAC systems. Here’s what the data—and our experience tell us:
1. Indoor Air = 2–5x More Polluted Than Outside
Most homes we test have higher indoor pollution than outdoor levels.
EPA confirms: indoor air is often 2–5 times worse.
2. You spend 90% of your Time Indoors
Families breathe indoor air most of the day, at home, at work, or school.
That’s why your HVAC filter quality directly impacts your health.
3. Dirty Filters Waste Energy & Money
HVAC pros tell us: clogged filters = stressed systems.
DOE reports: Clean filters can reduce energy use by up to 15%.
