The 5 Best Air Purifiers With No Ozone-Producing Features

‍Ever wondered how air purifiers generate Ozone? Do you have an air purifier that produces Ozone? Then you are not alone; in this article, we will learn how Ozone can be beneficial and harmful. Many air purifiers use an ozone-producing feature to remove odors, microorganisms, and viruses from the air and other contaminants. But you must use these devices cautiously because Ozone is also a harmful gas that can cause permanent lung damage when inhaled in high concentrations. But first, if you don’t have time to read all about Ozone air purifiers, here are our top 5 Air Purifiers with No Ozone Producing Features:

  1. BLUEAIR Air Purifier with Mechanical Filtration
  2. Germ Guardian Air Purifier Activated Charcoal Filter
  3. Holmes Air Purifier with Odor-Activated Ionizer
  4. Whirlpool Whispure Activated Carbon
  5. Coway Airmega 400 Air Purifier with Smart Technology

Also, please continue to read to learn more about Ozone producing air purifiers, how they work, the side effects, and our top ozone air purifier reviews.

What is Ozone?

Ozone is a type of gas containing three oxygen atoms. It is formed whenever ultraviolet light or electric sparks break apart a different kind of gas called oxygen, which consists of only one or two oxygen atoms. Ozone has many uses because it reacts easily with other chemicals and doesn’t react further with anything after it has reacted once. Furthermore, Ozone has several properties that make it useful for different applications.

Ozone Generator How It Works?

A typical ozone-generator air purifier electrically charges the air passing over an ozone-producing substance, such as UV-sterilized titanium dioxide. This causes the substance to break apart (oxidize). Ozone is formed as electrons pass from the ozone-producing substance to the negatively charged particles in the air. Unlike most oxidizers, Ozone quickly breaks down into oxygen, so it does not add to indoor pollution; it only cleans it up. 

Some of the harmful effects of Ozone can be reduced by the placement of the air purifier and the type of air purifier used. First, you will place a good air purifier in a central location of the home, and this is because ozone levels are highest near the air purifier and drop off as you move away from the device. Hence, keeping enough distance between the air purifier and the people in the home is important.

What are Ozone Air Purifier Dangers?

The primary danger surrounding ozone-producing air purifiers is the risk of overexposure. During normal operation, an ozone air purifier will have an indicator light to remind you to turn it off and unplug it when not in use. However, some air purifiers do not have indicators or automatic shutoff mechanisms; they can also be used in conjunction with a fan or other device that cannot sense the presence of Ozone in the air. 

Some ozone-producing air purifiers also have a timer that turns the device off after a certain amount of time; however, there is still a risk of overexposure if the device is left on while the people in the home are sleeping. To avoid overexposure, keep the air purifier in a central location, keep a safe distance between yourself and the air purifier, and turn off the device and unplug it when not in use.

Ozone Air Purifier Side Effects

Shortness of breath, chest pain, and coughing can occur in adults and children who inhale high quantities of Ozone for a brief period (minutes or hours). High ozone exposure might make asthma symptoms worse. People with cardiac problems may experience worsening symptoms after briefly inhaling Ozone. Ozone can interact with other airborne substances to create new substances and small particles that irritate the eyes, nose, throat, and lungs.

Long-term (years) ozone exposure in children may cause irreversible lung damage, but this health consequence is less certain. According to some data, children who engage in outdoor activities in ozone-heavy environments are more likely to acquire asthma.

Can Air Purifiers Remove Ozone?

Most popular air purifiers cannot remove Ozone from the air since it is a gas rather than a particle. Therefore, ozone levels won’t be affected by a HEPA filter or any other mechanical filter, including UV-C filters, ionizers, and ozone generators; these devices produce Ozone as a byproduct.

However, the same properties that make Ozone potentially dangerous also allow it to be removed from the air using a different technique called activated carbon. The Aberstorm Air ScrubberOpens in a new tab. is one of many activated carbon filters with multiple molecular sites for ozone molecules to attach to. This is why filters remove around 60% of the Ozone with activated carbon.

Another way to remove Ozone is through passive filtration; using building materials that can neutralize Ozone and lower ozone levels, such as activated carbon matsOpens in a new tab., is another method of removing Ozone.

How to Know if Air Purifier has Ozone?

It has been shown that some ionization air purifiers can increase the number of dangerous substances in the air. To determine whether your purifier emits hazardous substances, take the following actions:

  • Identify the purifier’s manufacturer and model. 
  • Next, look at the air purifier’s label on the back. 
  • For the model of your air purifier, look in the “Type” column.

Under the type column, air purifiers that could produce Ozone and other dangerous substances are labeled “Electrical.” Those labeled as “Mechanical” do not produce ions or Ozone.

Air purifiers with no ozone-producing features are safer than those with Ozone to clean the air. Ozone is a natural and useful oxidizing agent when produced in small amounts. However, ozone-producing air purifiers create large amounts of Ozone that can cause lung damage if the device is not used properly. Many air purifiers use different methods to clean the air without producing Ozone. Therefore, choosing an air purifier that does not produce Ozone is vital to avoid overexposure to this harmful gas.
