Finding the exact 22.25x25x1 size air filter for your HVAC or furnace system can be frustrating—many big-box stores don’t stock it, and generic replacements often compromise performance. At Filterbuy.com, we manufacture this specific size in-house to ensure a perfect fit and optimal airflow for your system.
Our filters are made in the USA with high-quality, pleated synthetic media that traps up to 95% of airborne particles—including dust, pollen, pet dander, and smoke—depending on the MERV rating you choose (MERV 8, 11, or 13).

“We started manufacturing uncommon sizes like 22.25x25x1 because we saw how often homeowners were forced to compromise with ill-fitting filters. Over the years, we’ve learned that even a quarter-inch off can impact airflow, system efficiency, and air quality. That’s why every filter we produce is made to order, using materials we trust in our own homes.” — HVAC Experts
At Filterbuy, we combine industry research with real homeowner feedback. Here’s what we’ve learned and what the data shows:
Indoor Air Is Often More Polluted Than Outdoors
Americans spend about 90% of their time indoors.
Indoor pollutant levels can be 2 to 5 times higher than outside.
Many homeowners don’t realize the impact this has on health. 🔗 EPA.gov – Indoor Air Quality
MERV Ratings Directly Affect Air Quality
Higher MERV filters capture smaller particles like pollen, smoke, and pet dander.
Choosing the right MERV rating improves comfort and allergy relief.
EPA confirms higher MERV means better filtration for particles 0.3–10 microns. 🔗 EPA.gov – What Is a MERV Rating?
Regular Filter Replacement Saves Energy and Money
Clogged filters reduce airflow and increase energy bills.
Timely replacement keeps HVAC systems efficient.
The U.S. Department of Energy stresses the importance of routine filter changes. 🔗 Energy.gov – Air Conditioner Maintenance
Choosing the right air filter is more than picking a size from the shelf. It’s about precision, quality, and understanding your home’s unique needs.
From our experience at Filterbuy, here’s what matters most:
Many HVAC systems require uncommon sizes like 22.25x25x1, which standard filters don’t always fit.
A perfect fit improves airflow, system efficiency, and indoor air quality.
Selecting the right MERV rating helps trap the particles that matter most for your health.
Using high-quality filters extends the life of your HVAC system and lowers energy costs.
Why settle for less? Investing in the right filter size and quality is a small change that delivers big benefits for your home environment.
At Filterbuy.com, we combine industry standards with real-world insights to bring you filters that truly fit your needs—because clean air and efficient systems shouldn’t be a compromise.
