Activated Carbon Air Filter Vs Hepa

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.

Activated carbon air filter vs hepa.

However due to differences in filtering capabilities hepa and carbon filters are often used in different industries. The technology behind this system is very different than the one used with hepa filters. Carbon filters remove bad odor. In air purification systems hepa media is generally utilized in combination with activated carbon media to provide odor removal regardless of the smell s source whether it s caused by.

Unlike hepa filters carbon uses absorption taking the contaminants into its porous surface. Carbon filters are used in air purifiers to absorb remove and capture particulate in the air davidson said. Carbon filter job is different. 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.

All hepa filters are tested and certified to be at least 99 97 efficiency in. It is used in water purification as well as air filtering among other things like gas processing. 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. Airborne particulates react chemically with the carbon in the filter causing it to.

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. Carbon filters use activated carbon to remove microbes and other impurities in the air. Hepa air filters are not merv rated as they exceed the ashrae test protocol 52 2 used in determining the merv ratings. You would think that hepa filter is all you need but you also need charcoal activated carbon filter.

Carbon filters remove bad smells and bad odors from the air room.
