What are the different types of air purifier filters?
HEPA Filter – HEPA stands for High Efficiency Particulate Absorbing /or/ Arresting
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. Particles that are smaller or larger are trapped with even higher efficiency.
A HEPA filter has been tested and you are assured of their filtering quality.
HEPA-Like Filter – a HEPA-“like” filter may be able to trap some airborne particles, but does not do so at the rating of a true HEPA filter.
Carbon Filter – a carbon filter removes larger particles and eliminates odors in the air. A carbon filter will remove almost any type of odor.
