Why Are Air Filters Rated?

The quality of an air filter is assessed by its rating, which tells you what capacity the filter has in blocking our particulates in the air. The college the rating (for MERV, FPR, and MPR), the smaller the air and dust particles your home air conditioning air filter can capture.

Without a standardized air filter rating method, homeowners and other HVAC enthusiasts are left in the dark on how well their air filter works against a broad range of airborne particles, including:

Dust
Pollen
Smoke
Pet dander
Hair
Odors
Bacteria
Airborne viruses

When information technology comes to assessing air filter filtration capacity, we use a term "micron" which allows usa to know how the smallest size of particle that an air filter tin cake.

Micron sizes can range anywhere from microscopic to visible to the human eye. Here'southward a handy nautical chart to give you an thought of the range of micron sizes:

It'south important to annotation that annihilation in the size range betwixt .001 microns and 10 microns tin can achieve deep into the lungs by existence inhaled. Any particulates nether around 100 microns can actually be inhaled into the olfactory organ.

The MERV, MPR, and FPR rating systems each consist of a range of numbers that stand for the filtration effectiveness based on the micron size that it can filter out. Beneath, we'll pause downwards where the rating systems come from and how to apply them when shopping for your next filter.

MERV Air Filter Ratings

MERV stands for "Minimum Efficiency Rating Value."

Every air or furnace filter in the U.s. carries a MERV rating, which is the merely nationally regulated rating system for air filters.

MERV ratings run on a 1-20 scale that designates the effectiveness of filters to capture certain particle sizes. The higher the MERV rating, the more particles it captures.

If the MERV rating is too high (above MERV 13), however, it can increase system backpressure and cake air flow through your central air system, worsening the effectiveness of your HVAC organisation.
