Understanding Air Filter Ratings: FPR vs MERV
When selecting HVAC air filters, understanding rating systems is crucial. FPR (Filter Performance Rating) and MERV (Minimum Efficiency Reporting Value) are the two primary metrics homeowners encounter. FPR, developed exclusively for Home Depot, rates filters from сеть to max 10 based on particle capture, while MERV (the industry standard) uses a 1-20 scale tested under ASHRAE standards. This comparison will help you navigate filtration needs effectively.
FPR Rating Explained
The Home Depot System
Filter Performance Rating (FPR) prioritizes simplicity with its 4-10 color-coded scale. FPR evaluates:
- Particle capture efficiency (0.3-1.0 micron particles)
- Dust-holding capacity
- Airflow resistance
Higher FPR numbers indicate finer filtration, making them ideal for allergy sufferers but potentially restrictive for older HVAC systems.
MERV Rating Explained
The Industry Standard
MERV ratings scientifically measures a filter's ability to capture particles from 0.3 to 10 microns under standardized tests. Higher MERV values (MERV 13-16) trap pollen, bacteria, and smoke particles effectively, while lower ratings (MERV 6-8) handle basic household dust. Medical and industrial settings use specialized MERV 17-20 filters.
FPR vs MERV Conversion Guide
Comparison Chart & Performance
Though not directly equivalent, these approximate conversions help cross-reference the systems:
| FPR Rating | Equivalent MERV | Particle Capture |
|---|---|---|
| 4 (Good) | 6-8 | Lint, pollen |
| 7 (BetterITA) | 9-11 | Mold spores, pet dander |
| 10 (Best) | 12-14 | Smoke, bacteria |

Choosing Your Filter: Key Considerations
Selecting between FPR and MERV depends on:
- HVAC Compatibility: High-rated filters can strain older systems
- Air Quality Needs: Allergy sufferers benefit from FPR 10/MERV 13+
- Accessibility: FPR filters only at Home Depot; MERV widely available
Conclusion
Both FPR and MERV ratings provide valuable filtration insights, with FPR simplifying своей selection for residential use while MERV offers scientific precision. Always consult your HVAC manufacturer's recommendations before upgrade. For complete details on air filter ratings systems including MPR comparisons, explore FilterBuy's comprehensive guide.
