Air Filter Cfm Ratings

Air filter rating system merv ratings.

Air filter cfm ratings.

The filter rating system is known as merv. However filters with merv ratings above a merv 13 tend to restrict airflow. Clean air delivery rate cadr is a figure of merit that is the cubic feet per minute cfm of air that has had all the particles of a given size distribution removed. Filters with higher merv ratings trap small particles more effectively than filters with lower merv ratings.

An air filter s minimum efficiency reporting value merv rating measures how effectively the filter stops dust and other contaminants from passing through the filter and into the air stream. Air filters indoor air quality. This is a us based system. What is a hepa filter.

Cfm measures air purification efficiency an important measurement provided by manufacturers is the cfm value for their units. This type of air filter can theoretically remove at least 99 97 of dust pollen mold bacteria and any airborne particles with a size of 0 3 microns µm. Lafc oc 1000 cfm has a 4 chamber carbon filter and the maxum can be paired with the m super carbon for odors around the home or office. Merv stands for minimum efficiency rating value.

Cfm stands for cubic feet per minute and this number provides insight into the efficiency of the air purifier namely how many cubic feet per minute this air purifier can scrub. Take control of the air you breathe. Medify ma 112 air purifier. It is an acronym for high efficiency particulate air filter as officially defined by the u s.

It is printed on the packaging. For reference a typical dust particle is between 2 and 8 microns while pollen starts at 7 microns and can get up to 70 microns in size. If you buy air filters for your furnace system you have come across this rating system. For air filters that have air flowing through them it is the fraction of particles of a particular size distribution that have been removed from the air multiplied by the air flow rate in cfm through the device.

It is capable of cleaning up to 2 100 square feet of room size in just 30 minutes or 1 050 square feet in only 15 minutes. While merv ratings reflect a filter s ability to trap both microscopic and macroscopic particles mpr ratings only grade a filter on its capacity to remove particles from 0 3 to 1 microns. Hepa is a type of pleated mechanical air filter. Commercial and industrial the la2 rc2 and la2000 offer over 1600 cfm of industrial air cleaning strength.
