5″ filters give you maximum filtration with minimal maintenance — lasting up to 12 months while handling higher MERV ratings without restricting airflow.
Sizing note:
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.

They improve system performance and lifespan by preventing particle buildup. This creates a cleaner environment ideal for allergy sufferers.
Its high rating provides an impressive level of filtration. It excels in dust capture and allergen removal. This efficiency substantially improves indoor air quality. It’s best for households with allergy sufferers or those wanting to live healthier.
Regular maintenance needs timely filter replacement. This is to keep your system efficient and improve indoor air quality. Replace the filter if it looks dirty, even if it's not at the end of its lifespan.
When discussing ratings, MERV 16 offers greater efficiency. They excel in dust capture and allergen reduction, thereby improving indoor air quality significantly more than MERV 13 filters. However, the enhanced efficiency of MERV 16 negatively impacts airflow, potentially straining system performance.
MERV ratings ameasure the efficiency of filtersin trapping and removing air pollutants. A MERV 14 filter exhibits a high level of filter efficiency, capturing minute particles such as dust mites, tobacco smoke, and eacteria. However, this increased efficiency potentially impacts HVAC performance.
It offers better filtration, capturing smaller particles than lower-rated filters and greatly improves indoor air quality. It’s ideal for those with allergies or respiratory issues. The effectiveness of a MERV 13 filter depends on your HVAC system's design and condition.
Though highly efficient, MERV 13 filters have potential drawbacks. Their advantages include superior air filtration and the capacity to capture smaller particles, such as bacteria, viruses and allergens. These benefits may come at a cost.
To ensure efficient airflow, consider your HVAC's performance and compatibility with different MERV ratings. Most residential systems comfortably handle filters with MERV ratings of 1 to 13, ensuring a balance between particle filtration and airflow efficiency.
A higher MERV rating offers better filtration but may not suit all AC systems. It indicates a filter's efficiency in trapping airborne particles, with higher ratings capturing smaller particles more effectively.
The pleated efficiency is undeniably superior when compared to traditional flat ones, as the pleats provide a larger surface area for capturing contaminants. The very pleats that increase the effectiveness also restrict airflow. Especially if it is not sized correctly for the system.
The frequency of changes depends on several factors, including the type, the overall air quality, and the presence of pets or allergies within the household. Generally, bare 1-2 inches should be changed every three months, while more substantial 4-5 inches last up to six months.
Without one, your system becomes vulnerable to dust, dirt, and other airborne particles. This can damage the filter over time. These particles build up within the system, causing it to work harder than necessary, potentially leading to overheating and system failure.
