Understanding filter performance ratings can be a bit confusing, but don't worry, I'm here to break it down for you.
A filter performance rating is a measure of how well a filter can capture particles and contaminants from the air.
There are three main types of filter performance ratings: MERV, FPR, and HEPA. MERV stands for Minimum Efficiency Reporting Value, which rates filters from 1 to 20 based on their ability to capture particles.
Filters with a higher MERV rating are more effective at capturing smaller particles. For example, a MERV 17 filter can capture particles as small as 0.3 microns.
FPR, or Filter Performance Rating, rates filters from 1 to 13 based on their ability to capture larger particles. A filter with a higher FPR rating is better at capturing larger particles.
HEPA filters, on the other hand, are rated based on their ability to capture 99.97% of particles as small as 0.3 microns.
HEPA filters are often used in medical facilities and laboratories where high air quality is crucial.

What is Filter Performance?
Filter performance is a measure of how well an air filter can capture particles and contaminants in the air. MERV ratings, for example, range from 1-16 and indicate the filter's ability to trap particles of various sizes.
The lower the MERV number, the lower the filtering efficiency will be, and vice versa. Filters with higher MERV ratings can capture smaller particles, making them more effective at removing allergens and other airborne pollutants.
FPR, or Filter Performance Rating, was developed by The Home Depot and rates filters on a scale of 1 to 10. Higher numbers indicate better filtration performance.
Here's a breakdown of the MERV rating tiers, categorized by particle size:
- 3-10 microns: Larger particles, including dust and allergens
- 1-3 microns: Medium-sized particles, including some bacteria and viruses
- .03-1 microns: Smaller particles, including smoke and other microscopic contaminants
While FPR doesn't measure performance over a wide range of particle sizes, it does aim to capture both microscopic and larger particles, making it a useful metric for evaluating filter performance.
Understanding Filter Ratings
Filter ratings can be confusing, but understanding them can make a big difference in your home's air quality. The FPR rating system, developed by Home Depot, uses a numerical value to show how well a filter cleans the air.
The FPR rating is similar to the MERV rating, but it has its own unique characteristics. While MERV ratings can go as high as 20, FPR ratings start at 4 and go up to a maximum of 10.
The FPR rating system also uses colors to represent different levels of filtration. These colors include green, red, purple, and black, each with its own unique measure of evaluation.
If you're considering upgrading to a high FPR filter, be aware that it may restrict airflow if your HVAC system isn't designed to handle it. Always check your system's specifications before selecting a filter.
FPR filters can be divided into four categories based on their rating:
- 1-4: Basic filtration, good for dust and lint.
- 5-7: Medium filtration, effective for pollen, pet dander, and mold spores.
- 8-10: High filtration, best for smoke, bacteria, and fine particles.
Here's a breakdown of the benefits of using FPR filters:
- Reduced exposure to airborne allergens, toxins, and irritants
- Better concentration
- Improved sanitary conditions by OSHA standards
- Chemical / biological contamination is controlled
