Industrial air filters, air purification and sanitization, is necessary for industries that expel odors from their process plants.

Industrial air filtration

What is an activated carbon air filter?

The carbon gas filter is the most commonly used filter for gas removal. They are designed to filter air through a layer of activated carbon and are commonly used to combat volatile organic compounds emitted by common household products. They are also commonly used to remove odors from the air such as cigarette smoke. They cannot remove fine particles such as mold, dust or pollen from the air.

How is carbon activated?

Activated carbon is carbon that has undergone additional processing to better retain gas molecules. First, hot air, carbon dioxide or water vapor is injected into it, creating a network of small holes in the carbon, greatly increasing its surface area.

This creates more places where molecules can be trapped and makes the charcoal work much more effectively as a filter medium. One gram of activated carbon can have an internal surface area of hundreds of square feet.

Effective use of activated carbon air filter in air.

Carbon air filters can be an important part of your process air filtration system but they must be used correctly.

Be sure to use enough carbon. Some filters claim to be activated carbon filters but only use trace amounts of carbon. These will not work because they become saturated almost instantly. Of course not all carbons are the same and some may have more binding sites (and saturation potential) than others. But in general the more carbon you use the more effective it will be because it will make more adsorption sites to bind to.

Air flow is very important. To remove as many contaminants as possible from the air the air must pass through the carbon as much as possible. A filter with a good carbon content, sufficient thickness and a long service life will be much more effective than a filter with a thin layer of carbon.

Change your carbon filter.

Once the charcoal is saturated it will lose its effectiveness as an air filter. It is imperative to replace it with a new charcoal filter when this happens. The problem is that there is no perfect way to tell when the charcoal is saturated. Sometimes you’ll notice the smell; sometimes you won’t. You can follow the manufacturer’s instructions and change it regularly although this is only a rough estimate.

Carbon becomes saturated depending on its use and the amount of contaminants it is exposed to. Replacing a charcoal filter is an expensive investment but a monthly replacement schedule is a good place to start.
Keep in mind that according to the EPA gas phase filters such as activated carbon filters cannot easily remove carbon monoxide so other important steps must be taken such as having a carbon monoxide detector on a machine to prevent exposure.

Air ozonifier

When looking for ways to purify the air and reduce odors in your home you can find quality personal ozone generators for sale.

They produce relatively high concentrations of ozone but have no other particulate filtering function. They are used to eliminate odors but are completely ineffective at eliminating airborne allergens such as mold and pollen. The word “generator” in the name will usually tell you that the device uses ozone technology.

There are commercial grade ozone generators that perform the same function as consumer grade personal ozone generators.

These should only be used by qualified professionals and only in specific contexts. Commercial grade ozone generators produce such high concentrations of ozone. They must be used according to strict instructions and should never be used in an occupied room.

If you are looking for a quality air purifier we recommend a few to safely remove irritants and odors from indoor air. None of them use ozone technology.
