Do you need an air sanitizer

If you are looking to better understand what an air sanitizer is and whether you need one, then you’ve come to the right place. In this article, we take a deeper look at air sanitizers and uncover facts that people tend to ignore.

Let us start by defining what they are and what they do.

What are air sanitizers?

Air sanitizers are disinfectants that clean the air by removing micro-organisms. They are also intended to slow down or eliminate the development of certain microbiological organisms such as viruses, bacteria or even fungi.

By eliminating such viruses and bacteria present in the air, the threat of transmitting them 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.

What are the ingredients?

The active ingredients used in the aerosol are mostly glycols. This includes triethylene glycol which is used as an air sanitizer. According to the United States Environmental Protection Agency, glycol vapours drastically reduce the number of airborne microorganisms under the right temperature and humidity.

In another study, when analysing a particular air sanitizer product, it was found that some of its ingredients pose a risk for human health. Ingredients were classified into three categories: active ingredients, inert ingredients, and secret ingredients. The latter refers to ingredients that were not listed on the label of that product but were found in testing.

They include Diethyl Isophthalate and Dimethyl Isophthalate. The effects of Diethyl Isophthalate include limited evidence as a developmental/reproductive organ system toxicant, immune system toxicant and allergen, and an endocrine system disruption; classification as potentially nontoxic and harmless to the non-reproductive organ system, but animal lab studies indicate that at moderate doses it is (USDHHS, Brown, EWG).

The effects of Dimethyl Isophthalate include limited evidence as a reproductive system toxicant, and immune system toxicant and allergen; strong evidence as a known respiratory system toxicant; and classification as a non-carcinogen, and as potentially nontoxic and harmless to the non-reproductive organ system, but animal lab studies indicate that at moderate doses it is (USDHHS, Brown, EWG).

Effectiveness of air sanitizer

To be effective, the air sanitizer must dispense the aerosol at a constant rate with constant volumes. Evidence has 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. They are also limited in the sense that they are only effective in small enclosed areas.

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.

Air sanitizer vs. air purifier

Do not confuse air sanitizers with air purifiers. The way air purifiers work is by trapping particles in the air circulator while the air sanitizer sprays a special aerosol into the air. That aerosol then acts on the bacteria or viruses in the air quickly. Some purifiers take a much longer time to clean the air. However, Purlife’s air purifier can clean the air in 15 minutes.

The air purifier acts as a filter while the air sanitizer acts more as a disinfectant. However, air sanitizers are unable to remove things such as allergens.
