don't know where to look

The choices you have when it comes to finding the best air purifier can be overwhelming, especially if you don't know where to look! So how do you know which one is best for your needs? The truth is, there are a lot of things that you need to keep in mind.

Thanks to technology, we can now control the humidity and air quality in our homes at the touch of a few buttons within a matter of minutes. But not all these air purifiers are created equal, and it's important that we choose wisely and buy something worth its price.

Do all air purifiers emit ozone

There's no ozone emission from air purifiers that use HEPA filters. There may be some from other type of machine

Ozone is produced along with nitric oxide, and when these two compounds are in the air, they will combine to form ozone. A certain amount of ozone is healthy for us, but when the level of ozone in the air increases too much, it can cause serious health problems.

So what exactly is the fine line between too much and not enough? It's extremely difficult to determine this limit, as there is no standard measurement for how much an air purifier should emit. Therefore, we can't say that all ozone-producing machines will cause harm. However, it's a good idea to be cautious and pay attention to your symptoms before you start running an air purifier that creates ozone in your house or office.

Do hospitals use ozone generators?

Yes, they do. Hospitals use ozone generators to decontaminate rooms and equipment from the inside.

Ozone kills most bacteria, viruses and fungi on surfaces, in air and water. It also disinfects respiratory germs (bacteria) from the air (also known as aerosolized infection control).

Hospitals save money by decontaminating their air and surfaces with ozone instead of using high-powered disinfectants and autoclaving. Ozone machines are easy to use. They are quiet, inexpensive to run, require no maintenance or cleaning aside from regular filter replacements.

Is ozone safe to breathe?

Not really, no. Ozone may be a powerful disinfectant, killing bacteria and other viruses in the air, but it's actually an irritant to the lungs. We might be able to smell it, but we can't breathe it without negative effects. Some people are even allergic to ozone and could have serious reactions from exposure.

The good news is that you don't have to worry about breathing ozone if you use an air purifier. This is because air purifiers produce extremely small amounts of ozone that dissipate very quickly—much too quickly for them to be harmful in any way.

Can you smell ozone?

Sometimes, ozone molecules form in the air that seem like a rotten egg smell. This is because ozone formed from the exhaust of cars and air conditioners, often called "smog," or create a stable, high concentration of ozone in certain areas. Ozone irritates the eyes and skin and has been linked to respiratory problems such as asthma. Ozone can be smelt by some people who are sensitive to it

What are the symptoms of ozone exposure?

People who are sensitive to smog can expect symptoms much like those of other respiratory conditions such as hay fever and asthma. These symptoms include:

  • Sneezing
  • Coughing
  • Chest tightness and pain-Fatigue

People who have been exposed to ozone for long periods of time may experience conjunctivitis (inflammation of the eye's membrane) and other serious problems. In some cases, children who live near highways with elevated ozone levels or industrial plants have been found to have impaired lung development

Can you recover from ozone exposure?

Ozone exposure can cause a variety of health concerns, including asthma attacks. However, in some cases you may be able to recover from ozone exposure if you seek prompt and proper medical care.

How do I know whether to seek treatment?

Ozone exposure can cause a variety of health concerns, including asthma attacks or chest pains. Your symptoms may differ depending on the level of ozone exposure. You may also have different symptoms at different times and levels of exposure. Many people who are exposed to high levels of ozone have no or minor symptoms, while others who are not as sensitive will experience more severe symptoms.

How many ppm of ozone is dangerous?

The NIOSH exposure limit for ozone is 0.1 ppm. This means that anyone who is exposed to more than 0.1 ppm of ozone should immediately seek medical attention.

Other Health Benefits

A number of studies have been performed to determine exactly what effects ozone will have on humans. Ozone exposure, when the levels are high enough to cause damage, is not something that people should take lightly.

Symptoms of exposure to ozone include: headache, nausea, and eye irritation . Oftentimes, this will be accompanied with coughing and shortness of breath. This happens most often when the public is exposed to ozone from air pollution. It is not uncommon for people to be easily irritated by its presence in air.


Ozone is a naturally occurring gas that has many benefits but can also have negative effects on the people around it when the levels become too high. Ozone will kill mold, disinfect, and cleanse the air; however, breathing it in is not healthy.

Many studies have been conducted to determine exactly what effects ozone will have on humans and these studies show that when people are exposed to too much ozone they can develop symptoms such as coughing, eye irritation, chest pain, and even death. So you should stay away from areas of high ozone and always keep your nose open for bad smells.

It is best if you can avoid breathing in ozone at all. If you do want to get rid of the smell, then get yourself one of our air purifiers to help remove it.

Other Questions

What is the 8 hour ozone standard?

The 2008 ozone standard is set at a level of 0.075 ppm averaged over an 8-hour period. This standard is set by the EPA with the goal of protecting human health and ecosystems. Any area with ozone levels above 0.075 ppm must meet National Ambient Air Quality Standards (NAAQS) to protect people from ozone-related health risks.

How long does ozone stay in your body?

30 minutes.

Who is most sensitive to ozone?

Older people are most likely to suffer from health problems due to ozone exposure. Active people of any age are also more susceptible to its damaging effects.

What is ozone therapy?

Using an ozone therapy machine, an individual can inhale ozone gas in order to treat an ailing body. While there are no harmful side effects, it has not yet been proven to be effective and the procedure is still in the realm of alternative medicine. One study did prove that people with bronchitis experienced lessened breathing and coughing after using an ozone machine.

When can you smell ozone?

Ozone is found in the air every day, but most of the time it will not make you smell anything. If there are high levels of pollution in your area, you will probably be able to notice the distinct odor of ozone by its unpleasant smell. The highest concentration of ozone is usually found between the hours of 10 am and 3 pm - during mid-afternoon.

This is when heat and sunlight are at their peak, causing pollutants to rise up from surface level. If you have a fireplace or fire pit outside, you can also notice smell during early evening hours just before sunset.
