Air Purifier for Odors
The human nose is very sensitive to small concentrations of certain compounds. We experience the sensation of an odor when an airborne molecule bonds to the surface of special receptors in our nose.1 Since it can require a very small amount of a substance in the air to produce a smell,2 even limited sources of air contamination can be detected. Volatile organic compounds, carbon-containing molecules which evaporate at room temperature, comprise a wide range of smells. An activated carbon filter, such as the kind found in an air purifier for odors, can reduce or remove these smells.
Some chemicals can be detected by the human nose in incredibly miniscule amounts. For example, a citrusy-smelling volatile organic compound called (Z)8-tetradecenal can be detected at concentrations of less than one in 100 billion.3 In other words, if one molecule for every 100 billion molecules in the air you inhale is an (Z)8-tetradecenal, you will be able to smell it.
With such an outsized ability, it is no wonder that it can be difficult to remove smells or odors from a living or working space. Even if you successfully eliminate the source of the smell, the molecules can continue to float around for long after the source is gone.
An air purifier with a carbon filter will circulate air through a filter of activated carbon, also called activated charcoal. The activated carbon has an enormous surface area relative to the volume it occupies, sometimes nearly as high as 4,000 square meters per gram.4 All of that surface area provides plenty of places for volatile organic compounds to adsorb, or adhere to the surface, of the carbon. The process is so effective that it is used to eliminate the smell of sewage from the gases that are released during waste treatment.5
In addition to being able to greatly reduce the incidence of smells and odors, a properly designed and maintained air purifier can improve air quality. In fact, some of the compounds we can smell are actually harmful chemicals. Benzene, a carcinogen, is detectable in concentrations as low as 1.5 parts per million.6 Removing this harmful substance from the air can benefit your health.
An air purifier for odors that uses an activated carbon filter can also serve as an effective air purifier for chemicals. Sometimes called an electric air cleaner, before the air is passed through the activated carbon, some type of filter for particulate matter is often used to prevent the carbon filter from becoming clogged. A HEPA air purifier is incredibly efficient at removing particulate matter like soot, dust, mold spores, and bacteria.

It depends on what method the air purifier uses to purify the air. A simple HEPA or ULPA filter that uses inert, fibrous media to capture particles from the air may not have an impact on odor. Air purifiers that use photocatalytic destruction to purify the air can greatly reduce the incidence of volatile organic compounds that constitute odors. Activated carbon filtration is very effective for odor control.8
The best way to eliminate an odor is to eliminate the source of the odor. The human nose is very sensitive and is able to detect very small traces of molecules, so removing the source of the smell will go a long way towards removing the smell. If the odor persists after removing the source of the odor, a professional service can treat your living space to remove persistent smells. For ongoing odor reduction, an activated carbon filter is effective.
Activated charcoal or activated carbon filters are very effective at removing odors. Keep in mind that an activated charcoal filter has a given lifetime. The amount of time a carbon or charcoal filter will remain useful depends on how heavily it is used. Once the filter has become saturated with odors and other volatile organic compounds, it can no longer remove odors from the air and will need to be replaced.
Boiling vinegar may temporarily overpower other smells. Unless you remove the source of the odor, once you stop boiling the vinegar, the odor will return. An air purifier for odors will continuously remove smells until the carbon filter becomes saturated, at which point the filter will need to be changed.
