Air Filter Cfm Ratings

Cfm measures air purification efficiency an important measurement provided by manufacturers is the cfm value for their units.

Air filter cfm ratings.

Merv stands for minimum efficiency rating value. Air filter rating system merv ratings. Hepa is a type of pleated mechanical air filter. 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.

It is printed on the packaging. However filters with merv ratings above a merv 13 tend to restrict airflow. Filters with higher merv ratings trap small particles more effectively than filters with lower merv ratings. 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.

This is a us based system. If you buy air filters for your furnace system you have come across this rating system. With a cadr of 560 cfm this is one of a small crop of air purifiers with one of the highest cadr ratings in the market at the moment. Commercial and industrial the la2 rc2 and la2000 offer over 1600 cfm of industrial air cleaning strength.

The filter rating system is known as merv. Air filters indoor air quality. 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. 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.

The higher the merv the higher the restriction of airflow. Take control of the air you breathe. 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.

The scale ranges from a value of 1 to 18. 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. 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. 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.
