Air Filter Cfm Ratings

However filters with merv ratings above a merv 13 tend to restrict airflow.

Air filter cfm ratings.

It is printed on the packaging. 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. Merv stands for minimum efficiency rating value.

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. Take control of the air you breathe. Air filter rating system merv ratings. 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.

Filters with higher merv ratings trap small particles more effectively than filters with lower merv ratings. Hepa is a type of pleated mechanical air filter. The higher the merv the higher the restriction of airflow. This is a us based system.

Medify ma 112 air purifier. What is a hepa filter. Cfm measures air purification efficiency an important measurement provided by manufacturers is the cfm value for their units. The scale ranges from a value of 1 to 18.

The filter rating system is known as merv. 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 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. It is an acronym for high efficiency particulate air filter as officially defined by the u s.

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 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. Commercial and industrial the la2 rc2 and la2000 offer over 1600 cfm of industrial air cleaning strength. 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.
