Air Filter Cfm Ratings

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.

Air filter cfm ratings.

Filters with higher merv ratings trap small particles more effectively than filters with lower merv ratings. Air filters indoor air quality. 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. Commercial and industrial the la2 rc2 and la2000 offer over 1600 cfm of industrial air cleaning strength.

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. If you buy air filters for your furnace system you have come across this rating system. Air filter rating system merv ratings. Take control of the air you breathe.

Cfm measures air purification efficiency an important measurement provided by manufacturers is the cfm value for their units. However filters with merv ratings above a merv 13 tend to restrict airflow. 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. 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. What is a hepa filter. It is printed on the packaging. It is an acronym for high efficiency particulate air filter as officially defined by the u s.

This is a us based system. 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. 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. The filter rating system is known as merv.

The higher the merv the higher the restriction of airflow. 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. 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.
