Custom Air Filters
Custom Air Filters Made to Your Exact Dimensions
Not every HVAC system uses standard filter sizes. For homes with unique return grilles, older units, or non-standard openings, custom air filters provide the perfect solution. These filters are manufactured to your exact dimensions, ensuring a proper fit and reliable filtration without gaps, airflow leaks, or performance loss.
The Importance of Proper Fit
A filter that doesn’t fit correctly can allow dust, pollen, and debris to bypass the filtration media entirely—reducing indoor air quality and introducing contaminants into the HVAC system. A custom-sized filter eliminates this issue by matching your required height, width, and depth precisely.
Choose Your MERV Level
Custom filters are available in multiple levels of filtration:
-
MERV 8: Basic dust and allergen control
-
MERV 11: Enhanced protection from pet dander, mold spores, and fine debris
-
MERV 13: Premium-grade filtration designed to capture smoke, bacteria, and tiny airborne particles
This flexibility ensures that even hard-to-fit HVAC systems can benefit from the same high-performance filtration used in standard sizes.
Built for Long-Lasting Performance
Our custom filters are made from durable materials, strong pleated media, and rigid frames that maintain shape under airflow pressure. This ensures reliable performance throughout the filter’s lifespan.
Ideal Applications
Custom HVAC filters are perfect for:
-
Older HVAC systems with non-standard openings
-
Homes with unique filter housing sizes
-
Commercial units requiring precise fit
-
Systems that can only accommodate specific thicknesses
-
Custom-built homes and renovations
