<h1>Carbon Air Filters: Why More is Better and Why You Must Replace Them On Time or Before</h1>

Activated carbon air filtration became the standard several years ago for effective removal of chemicals, gases, vapors, VOC’s, and odors simply because it really works. Carbon or charcoal is often activated by heat and / or chemical means that cause the carbon to be more ‘sticky’ or chemically attracted to various compounds and when they pass by the carbon, these compounds become ‘glued’ to the surface of the carbon granule, allowing the clean air to pass through the unit. Pretty smart. There are, however, a couple of key things to remember about carbon air purifier filters: 1) the more carbon, the better, and 2) you have to replace the carbon filter or the carbon itself regularly to avoid air quality issues. 

 

Assuming that the activated carbon is high quality, the more of it in the filter, the better, especially if the filter is thicker (i.e. a longer distance of carbon that the air has to go through). More carbon in thicker filters means the carbon will have more time to adsorb a higher percentage of pollutants in the air. Carbon filters, by the way, don’t absorb pollutants into the carbon; they rather 'adsorb' or cause pollutant to stick to the surface, which is one reason why smaller granular carbon does better because it has more surface area to be used) One more point about getting the most out of your carbon filters is to reduce the air speed going through the unit. This, too, allows for more time that the air and pollutants are in contact with the carbon, which allows for higher rates of removal than if the air is moving through the filter quickly.

 

Regarding replacing the carbon filters in you air cleaner or filtration system, it’s very important to replace them on time or a little before because all carbon, even premium military grade carbon filters, do become saturated over time, stops adsorbing the pollutants, and then your air purifier is blowing out or circulating air that hasn’t been cleaned. So definitely buy your replacement carbon filters and change them on time, before, or when you start to smell odors again to avoid an air quality problem. This is especially important for home workshops or industrial situations where hazardous chemicals are in the air—in those cases, you may want to also have an electronic VOC or other chemical compound detector running to alert you to the presence of those airborne pollutants as soon as they start blowing out of the unit (i.e. as soon as the carbon filter is ‘spent’).
