What is better than a HEPA filter?
As previously mentioned, both filters have been designed to remove very small particulate, but how efficient is each filter at removing the smallest of contaminants. … Rated at removing 99.999% of airborne contaminants, ULPA filters are considered more efficient than HEPA filters.
Will a HEPA filter catch mold spores?
Mold spores can vary tremendously in size, but the size range is generally between 4 microns up to about 20 microns (Li et al., 2011). This means even the smallest mold spores fall well within the HEPA specification, allowing a HEPA filter to trap most mold spores that pass through them.
What makes a HEPA filter?
HEPA, which stands for High Efficiency Particulate Air, is a designation used to describe filters that are able to trap 99.97 percent of particles that are 0.3 microns.
Are there different types of HEPA filters?
According to the Institute of Environmental Science and Technology, (IEST) with regard to performance, there are 6 types – A, B, C, D, E & F. Each has its own distinct characteristics as shown by chart 1 below.
