What Is a HEPA Filter?
A HEPA (High-Efficiency Particulate Air) filter is designed to capture a very high percentage of small airborne particles. True whole-home HEPA filtration for ducted HVAC systems typically requires a dedicated bypass unit, since standard duct filter slots aren't sized for full HEPA-grade media.
Why It Matters to You
Not every 'HEPA-style' filter sold for a standard filter slot performs like true HEPA media — whole-home HEPA filtration is a distinct product category worth discussing directly with a technician.
Practical Guidance
If whole-home HEPA-level filtration is the goal, ask specifically about a dedicated HEPA bypass system rather than assuming a higher-rated standard filter achieves the same result.
