Supporting Statistics: What Real HVAC Experience Confirms
1. Indoor Air Is Often More Polluted Than Outdoors
- EPA data shows indoor air can be 2–5x more polluted—and sometimes 100x higher than outdoor levels.
- We see this in the field: faster filter clogging, heavy dust on coils, and poor airflow in homes with inadequate filtration.

2. Fine Particles Reach Deep Into the Lungs—and Into HVAC Systems
- The EPA confirms PM2.5 particles can penetrate the lungs and even enter the bloodstream.
- In HVAC inspections, these same particles are the ones that slip through low-efficiency filters and coat internal components.
- Premium filters reduce this buildup noticeably.

3. Higher-MERV Filters Capture Far More Harmful Particles
- ASHRAE findings:
- MERV 13 = 85%+ efficiency (1–3 micron particles)
- MERV 14 = 90%+
- MERV 8 ≈ 20% for the same particle size
- We routinely see cleaner coils, steadier airflow, and fewer dust-related service calls after upgrading homeowners to high-MERV 4″ filters.
