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.

Carbon filters use activated carbon to remove microbes and other impurities in the air. Carbon filter job is different. Unlike hepa filters carbon uses absorption taking the contaminants into its porous surface. Airborne particulates react chemically with the carbon in the filter causing it to.

Both hepa filters and carbon filters work to improve indoor air quality. However due to differences in filtering capabilities hepa and carbon filters are often used in different industries. Carbon filters remove bad smells and bad odors from the air room. The technology behind this system is very different than the one used with hepa filters.

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. 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. This is often compared with the merv rating scale. Carbon filters remove bad odor.

Hepa air filters are not merv rated as they exceed the ashrae test protocol 52 2 used in determining the merv ratings. All hepa filters are tested and certified to be at least 99 97 efficiency in. 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 are used in air purifiers to absorb remove and capture particulate in the air davidson said.

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.
