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.

TL;DR: A 16x22.25x2 MERV 11 air filter is a two-inch pleated filter for furnaces, air conditioners, and heat pumps with a two-inch filter slot. MERV 11 is Filterbuy’s Superior tier, the one built for allergy sufferers, and it captures 95% of airborne particles. We cut, pleat, and frame every one to order in our own US plants, with fast and free 2-day delivery to most US states.
The 16x22.25x2 MERV 11 air filter is a pleated replacement filter for HVAC systems with a two-inch slot. Pleated just means the media is folded into ridges, which packs more surface area into the same frame. If the filter you pulled out reads 16x22.25x2, you’re in the right place. Check your HVAC manual to confirm which MERV tier your system takes, the same way you’d confirm a size.
Filterbuy’s MERV 11 is the Superior tier, and it captures 95% of airborne particles.
MERV 11 is the tier built for allergy sufferers, and for homes with pets or pollen coming in.
Order by nominal size, which is the number printed on your old filter frame. Here that’s 16x22.25x2.
Check your HVAC manual to confirm the MERV tier your system takes.
Can’t find your size? We cut custom filters to the eighth of an inch.
MERV stands for Minimum Efficiency Reporting Value, which is the industry scale for how much a filter catches. Higher numbers catch more. Filterbuy builds three tiers, and MERV 11 sits in the middle.
MPR is 3M's rating system and FPR is The Home Depot's. Neither is a Filterbuy rating.
MPR is 3M’s rating system and FPR is The Home Depot’s. Neither one is a Filterbuy rating, and we list them only so you can match what you bought last time.
Each tier exists for a different household. Pick the one that matches yours, then check your HVAC manual to confirm your system takes it.
MERV 8, Standard. The standard choice for most homes.
MERV 11, Superior. Allergies and asthma. Also pets and pollen.
MERV 13, Optimal. Smoke.
Odor Eliminator, carbon. Odors.

Most people have it in ten seconds.
Pull the old filter and read the frame. The nominal size is printed along the edge. If it says 16x22.25x2, you’re done. Nominal size is just the ordering name.
No old filter? Measure the slot opening, then order the nominal size that matches.
Size not listed? We cut custom air filters to the eighth of an inch.
Every filter is cut a little smaller than its nominal size on purpose. That small clearance is what lets it slide into the slot instead of jamming. Our air filter size chart lists every size we build, and it’s worth knowing that the badge on your furnace doesn’t determine your size. The slot does.
Here’s a test that beats any calendar: hold the filter up to a light. If light doesn’t come through the pleats, change it. If remembering is the hard part, Filterbuy auto-delivery sends replacements on your schedule and saves 5%.
We sell factory-direct, so buying in bulk drops the per-filter price sharply. Most homes change this filter three or four times a year, so a multi-pack is about a year of clean air in one shipment.
Pricing verified at filterbuy.com on August 9, 2026. Auto-delivery takes an additional 5% off.
Delivery is fast and free within 2 days to most US states. If the size turns out wrong, our free exchange policy sends you the right one.
Three findings from US federal agencies, for context.
1. A clean filter cuts air conditioner energy use by 5 to 15%.
Why it matters: changing on schedule protects your bill, not only your air.

2. One in four US adults has a diagnosed seasonal allergy.
25.2% of adults reported one in 2024, making it the most common allergic condition among US adults.

3. Allergens turn up in almost every US home.
More than nine in ten homes studied had at least three detectable allergens present.

It’s a two-inch filter, ordered by the nominal size printed on the frame: 16 by 22.25 by 2 inches. Order that number and it’ll fit a 16x22.25x2 slot.
MERV 8 for most homes, MERV 11 for allergy sufferers and homes with pets, MERV 13 for smoke, and Odor Eliminator for odors. Check your HVAC manual to confirm which tier your system takes.
It’ll fit, but we don’t recommend it. A 1-inch filter in a 2-inch rack can shift, rattle, and load up faster. Use the depth the slot was built for. In this size we also make 16x22.25x1 MERV 11 filters.
Up to 90 days in a typical home, 60 with pets or allergy sufferers, and 30 in smoke or smog areas.
We’re a manufacturer, not a reseller. Every filter is cut, pleated, and framed to order in our own US plants.
