Air Sanitizers

Air sanitizers and its uses


Air sanitizers are disinfectants that aim to remove micro organisms or micro biological organisms. It is also intended to slow down or eliminate the development or growth of certain micro biological organisms such viruses, bacteria or even fungi most in venues with many people. By eliminating such viruses and bacteria present in the air, the threat of transmitting such viruses is greatly reduced. Thus, air sanitizers are especially common at venues or areas such as hospitals, clinics and toilets where these bacteria or virus are most likely to be found.


Air sanitizer vs. air purifier


Air sanitizers are not to be confused with air purifiers. Air purifiers trap dust or other particles in the air circulator where as the air sanitizer sprays a special aerosol into the air. This special aerosol then is able to act on the bacteria or viruses in the air quickly. However, it would take a much longer time for the air purifier to clean the air and the time depends on the size of the open space it is treating. The air purifier acts as a filter where as the air sanitizer acts as more of a disinfectant. Both products have its uses and thus it would be very wise to use both an air purifier and air sanitizer at the same time. As air sanitizers are unable to remove things such as allergens. Furthermore, the air purifier is able to add a certain fragrance or smell to the air where as the air sanitizer does nothing more than disinfect the air.


Contents of the air sanitizer


The aerosol used mostly consists of glycols. This will include triethylene glycol which is used as an air sanitizer. Studies have shown that according to the United States environmental protection agency, glycol vapors produce a major difference in the number of air borne viruses or bacteria under the right temperature and humidity. However, the air sanitizer has to also dispense the aerosol at a constant rate with constant volumes. However, it was also shown that even with the presence of such products, it is not certain that the air sanitizers will completely eliminate all the bacteria that are present in the air. Thus, manufacturers have to be extremely cautious when making claims on the effectiveness of their air sanitizer products.


Some believe that the air sanitizer may not be very applicable in the real world as there may be many viruses and bacteria that the air sanitizer is unable to disinfect. Thus air sanitizers are limited in the sense that they are only effective in small enclosed areas.


Effectiveness of air sanitizer


There are certain ways to test the disinfectant. Such ways include comparing the disinfectants with other disinfectants and then ranking them in order. Most of the times, phenol is used as the baseline or the standard and it is often referred to as the phenol coefficient. How it works is that the disinfectant is tested on a microbe such as salmonella typhi or staphylococcus aureas, and those disinfectants which are less effective than phenol are give a coefficient lower than one where as those which did better and are more effective than phenol are given a coefficient that is higher that one.


However, this process takes up quite some time and a more general but less specific method would be to use the united states environmental protection agency’s classification. This method categorizes the level of effectiveness in disinfecting into three levels: low, intermediate and high. Low level of effectiveness only kills a small amount of bacteria and viruses. Intermediate level is able to kill most bacteria such as mycobacteria. The level of effectiveness is able to kill almost all the bacteria except spores.




Most air sanitizers can be found in toilets as they are small enclosed places. Most hospital areas and clinics also do use air sanitizers. Even some households use such products. However, it is only limited to indoor areas, thus as long as the area is enclosed then the air sanitizer would be able to do its job.
