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: 19.50x19.50x1.75" in → 20x20x2 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.

It offers distinct benefits. That includes the ability to trap and remove smaller particulates from the air, contributing to enhanced indoor air quality. It effectively captures various substances, making it preferable for households with allergy sufferers or those aiming for a healthier home environment.
This equipment helps maintain clean and healthy indoor air quality, thus providing substantial protection against allergens. Ensuring your system fits to handle them is critical, as they can strain some systems.
MERV 16 filters offer superior efficiency, trapping more minute particles than MERV 13. Thus, MERV 16 is a better option for environments where absolute cleanliness is required, such as hospitals or laboratories.
They have a life expectancy of 3 months under normal conditions. However, the replacement frequency varies due to several factors such as air quality and usage.
In terms of cost, MERV 13 is more expensive than MERV 11 due to its enhanced filtration capabilities. Ultimately, the decision between these two depends on specific individual needs and the air quality requirements of the home.
Higher ratings, such as 13 or 16, mean smaller pores for air to pass through, which strains systems not designed to handle them. This leads to increased energy usage and potentially shortens the lifespan of the system. Additionally, they require more frequent filter maintenance due to the smaller particles they catch.
The optimal levels for airflow typically range from 7 to 13. These values maintain a balance between efficiency and air resistance. Lower ones allow more airflow but trap fewer particles, whereas higher-rated ones capture more elements but may restrict airflow.
Consult with a professional to ensure your system fits handle this level without compromising efficiency or requiring excessive maintenance. Choosing the right one is crucial for maintaining optimal indoor air quality and system performance.
While MERV 14 might seem appealing, in most residential settings, MERV 13 provides a balanced solution, effectively improving air quality without compromising system performance. While both effectively improve indoor air quality, the choice between them should be guided by a careful analysis of your specific needs.
Despite their slightly higher cost, the superior performance of these equipment against mold spores makes them a worthwhile investment. They help maintain healthy indoor air quality.
Flat-panel, pleated, electrostatic, and HEPA, are among commonly used equipment. Each type has unique properties that make it effective for different HVAC needs. For optimal performance, regular maintenance is crucial.
This effectively captures smoke particles, preventing them from circulating in your home. Its superior filtration performance, compared to lower-rated ones, is due to its finer mesh design, which traps more and smaller particles. However, it's essential to change it regularly, as trapped particles clog it over time, reducing its effectiveness.
