Activated Carbon Air Filter Vs Hepa

It is used in water purification as well as air filtering among other things like gas processing.

Activated carbon air filter vs hepa.

Unlike hepa filters carbon uses absorption taking the contaminants into its porous surface. You would think that hepa filter is all you need but you also need charcoal activated carbon filter. However due to differences in filtering capabilities hepa and carbon filters are often used in different industries. All hepa filters are tested and certified to be at least 99 97 efficiency in.

Carbon filter job is different. Air oasis filters within the iadaptair use true hepa filtration alongside activated carbon. Ideally both of of these two filters should be used together given that they both filter out different contaminants this article will explore the differences between the two in more detail below. Carbon filters use activated carbon to remove microbes and other impurities in the air.

The technology behind this system is very different than the one used with hepa filters. Some filters claim to be hepa certified a standard for air filtration or made with carbon which may increase the potential for particulates to stick to the material blocking it from entering. Hepa air filters are not merv rated as they exceed the ashrae test protocol 52 2 used in determining the merv ratings. This nasa study of hepa filtration is quite technical but the graph on page 7 and the preceding paragraph do a good job of explaining why hepa filters are actually most efficient almost 100 at.

Carbon filters remove bad smells and bad odors from the air room. Beware that when you see a filter being rated as hepa like or hepa type it means that it does not comply with the high standard true hepa filters follow. Carbon filters remove bad odor. Airborne particulates react chemically with the carbon in the filter causing it to.

This is often compared with the merv rating scale.
