In the market of air purifiers, there are several kinds of manufacturing categories depending on their operation. Out of them, ozone-free air purifiers demand a different market value because of the word “Ozone”.

From today’s Know Your Facts, let us talk about these ozone-free air purifiers, why they are so controversial, and the best ozone-free air purifiers in 2022. Read and enjoy.

What is the Ozone?

You surely might have heard about Ozone (O3) from the protective shield of the earth’s upper atmosphere called the “Ozone layer. Because of this, most of us assume as Ozone is a friendly gas. Actually, it is not.

Most of us Know Ozone by the Ozone layer

According to the EPA and WHO reports, Ozone gas comes under the category of air pollutants with its higher oxidation capability. Exposure to this gas eventually leads to health conditions like chest pain, coughing, shortness of breath, and throat irritation.

Even though we assume Ozone is only staying in the upper atmosphere, actually it can be created by air pollutants, volatile organic compounds (VOC) and nitrogen oxides (NOx) in the daily process. So the risk of the Ozone is everywhere.

How are Air Purifiers creating Ozone?

Ozone generators inside the ozone air purifiers are commonly used to clean most air pollutants through their higher reactive capability. Even though it purifies the contaminants, it does not say Ozone is health-protective.

The mechanism behind ozone generation can explain simply as follows.

These generators send the atmospheric oxygen (O2) through a strong electrical charge and covert it into O3, which is more reactive than oxygen.

Due to the extra oxygen attachment, O3 has a higher oxidation capability to stabilize into the initial stage of O2 by releasing the extra oxygen. By applying to bacteria, fungus, germs, odor, and other kinds of pollutants, this instability of O3 eliminates them by destroying their cell wall.

Without higher precautions and well-trained guidelines, humans are highly restricted from using Ozone in purification due to its higher reactivity.

What are the Health Risks of Ozone Gas?

Exposure to the Ozone in our respiratory system is a critical factor which can quickly get health impacts. According to EPA, these have been identified as;

  1. Cause coughing and sore or scratchy throat.
  2. Make it more difficult to breathe deeply and vigorously and causes pain when taking a deep breath.
  3. Inflame and damage the airways.
  4. Make the lungs more susceptible to infection.
  5. Aggravate lung diseases such as asthma, emphysema, and chronic bronchitis.
  6. Increase the frequency of asthma attacks

There is a potential for several illnesses from ozone exposure

Even though you have a healthy respiratory system, there is a risk of getting an illness from ozone gas.
There are specific kinds of categories which directly might suffer from exposure to the ozone gas.

  1. People with asthma
  2. Children
  3. Elderly community
  4. Outdoor workers
  5. People who often smoke
  6. People with reduced intake of certain nutrients, such as vitamins C

In these risk categories, children stay top position due to weak respiratory systems and easy childhood health fragileness.

What should consider about Ozone Free Air Purifiers before buying?

We need to consider some simple factors before selecting an ozone-free air purifier.

1. Filters

Most mechanical filtration, including air purification systems, are Ozone free. Mostly Like HEPA filters.
Nevertheless, some add-ons like UV light, ionizers, and plasma cannot be assumed as 100% Ozone free. Minimizing their usage is much more suitable.

2. CADR value

CADR value, aka clean air delivery rate, is the fundamental factor your need to worry about before selecting an air purifier. It directly depends on the size of the room where the purifier is going to place. A big CADR valued air purifier when room size gets bigger is required.

3. Maintenance

Regular maintenance and filter change are essential requirements when you are going away from an ozone air purifier. Some purifiers come with three filtration systems, and some do not. When the filtration system is getting advanced, maintenance is also getting advanced.

Nevertheless, protection is much more wide-ranging than average. But, the choice is up to you.
