Supporting Statistics (with Filterbuy Insights & Experience)
At Filterbuy, we don’t just read the data—we test filters daily in real HVAC systems to see how the numbers translate into real-world air. Here’s what the most credible research shows, combined with what we’ve observed firsthand from years of filter manufacturing and customer feedback.
MERV 8 Filtration Efficiency – Verified by ASHRAE, Proven in the Field
According to ASHRAE, MERV 8 filters capture about 70% of particles sized 3–10 microns—the visible dust, pet dander, and lint you actually notice most at home. In our internal tests, these results match what we see in thousands of households: consistent dust control and balanced airflow that keeps systems running efficiently.

EPA: MERV 8 Captures What Matters for Everyday Homes
The EPA’s Indoor AirPLUS program confirms that MERV 8 filters remove common household particles like mold spores and animal dander—two of the biggest culprits for indoor allergens. Our experience aligns with that: customers who switch from fiberglass to pleated MERV 8 filters report visibly less buildup on surfaces and fewer sneeze-inducing irritants.

ENERGY STAR: Replace Every 90 Days to Protect Efficiency
ENERGY STAR recommends checking filters monthly and replacing them at least every three months to maintain airflow and energy efficiency. We’ve found that homes following this schedule not only save on energy bills but also extend HVAC life by reducing strain on blowers and coils.

When Higher MERV Ratings Matter – CDC & Harvard Findings
Studies supported by the CDC and Harvard’s Healthy Buildings Program show that using MERV 13 or higher can cut indoor PM2.5 by roughly 30% in certain environments. While MERV 8 is ideal for most residential systems, this research helps our customers decide when upgrading makes sense—especially for those with asthma, severe allergies, or urban air exposure.

Is MERV 8 enough?
Yes, for most residential systems. It provides the right balance between filtration and performance. If you have severe allergies or live in areas with heavy pollution, consider upgrading to MERV 11 or 13.
What’s the difference between MERV 8 and higher ratings?
Higher MERV filters capture smaller particles like smoke, but can reduce airflow in older systems. MERV 8 remains the smart middle ground—effective, efficient, and affordable for everyday home comfort.
Why choose pleated over fiberglass?
Pleated filters last longer, trap more particles, and perform better overall. Fiberglass filters are cheaper but less efficient and require more frequent replacements.
