3 Best Ozone Free Air Purifiers - 100% Effective, While the Safest for Your Health


An air purifier is intended to improve air quality, allowing you to breathe easier and healthier. Some ozone air purifiers on the market, however, make the air even worse.

According to EPA, ozone air purifiers will produce "ground-level" ozone, which is harmful to your health. Even low levels of ozone can cause health problems.

WHO and many health organizations classify "ground-level" ozone as a pollutant. Therefore, you should avoid ozone-generating products.

Here you can find the best ozone free air purifiers for your home, comprehensive explanations of ozone, how it affects your health, as well as the hottest questions about ozone free air purifiers.

1. What Is Ozone and Its Health Effects

Ozone is a colorless, pungent-smelling reactive gas made up of three oxygen atoms (O3) that can be found in two places on Earth: the stratosphere and the ground-level.

Stratospheric ozone, also known as the ozone layer, is a gas found in the Earth's stratosphere that can shield life on Earth from the ultraviolet component of incoming solar radiation. Therefore, it is referred to as "good ozone."

Ozone in the troposphere, also known as ground-level ozone, is "bad ozone." The EPA points out that it is the primary component of "smog."

Ground-level ozone is formed by chemical reactions. Below is the chemical formula.

NO(X) + VOCs + Heat & Sunlight = Ozone


  • VOCs: Volatile organic compounds.
  • NO(X) are common chemical terms for nitrogen oxides, such as N2O, NO2, N2O3, NO, and NO3. They are from oil and gas, industries, road traffic, and shipping.
  • Both NO(X) and VOCs are harmful to your health.

Breathing ground-level ozone can cause a variety of health problems, such as breathing difficulties, coughing, throat irritation, chest pain, and sniffles. Additionally, if you have asthma or bronchitis, it will aggravate your symptoms.

Ozone can also impair lung function and irritate the lung lining. Long-term exposure may result in lung tissue scarring.

2. Air Purifiers That Emit Ozone You Should Avoid

CARB, the California Air Resources Board, recommends against using ozone air purifiers since ozone is extremely harmful to all life.

UV and electronic air purifiers are the main examples of ozone-generating air purifiers that you can find on the market.

UV air purifiers use short-wave ultraviolet light to kill airborne pathogens and microorganisms such as bacteria and viruses.

Pros and cons: While UV air purifiers are very effective at removing bacteria and viruses from the air, they cannot effectively remove VOCs or other gases. The most important consideration is safety, as it will emit ozone while in operation.

There are two kinds of electronic air cleaners: ionic and electrostatic. Both air cleaners purify the air by emitting negative ions or static electricity, which can charge particles and cause them to stick to the built-in plates or fall from the air.

Pros and cons: Electronic air filters are less expensive. The filters of electrostatic air filters can be used permanently. However, they emit harmful ozone and are less effective at cleaning the air.

Although ionic air purifiers are effective at purifying the air, they emit ozone and fall-dust will settle on your furniture.

Therefore, you should avoid using the air purifiers listed above because they do not improve the air quality, but worsen it.

4. Ozone vs Zero Ozone Air Purifier - FAQs

Q1. Is Ozone Safe to Breathe?

No, unfortunately. According to EPA, ozone can be harmful to your health, causing breathing difficulties, irritated eyes, and other respiratory symptoms. Long-term exposure may cause lung tissue scarring. Thus, you should avoid using any ozone-producing products.

Q2. Are Ozone Air Purifiers Harmful?

Sadly, the answer is yes.

CARB has claimed that many commercial ozone air purifiers produce more than 5,000 mg of ozone per hour of operation, which can lead to unhealthy levels of ozone in the indoor air. Furthermore, no matter how much it produces, ozone can harm your health.

Q3. What Is an Ozone Free Air Purifier?

As the name suggests, an ozone free air purifier doesn't produce ozone.

Most health organizations and experts recommend HEPA air filters because they are completely ozone free and 100% effective.

Q4. How to Know If Air Purifier Has Ozone?

Ozone has a strong odor that is similar to chlorine bleach. However, if it is at a low level, you may be unaware. While the air purifier is running, you can use an ozone gas detector to measure ozone concentrations. If the ozone level rises, your air cleaner may emit ozone.

The main ozone air purifiers on the market that you should avoid are UV air purifiers, ionic air purifiers, and electrostatic air purifiers.

Q5. Are Ozone Free Air Purifiers Safe?

Yes, of course! Air purifiers without ozone are safe for use in the home.

When it comes to finding ozone-free air purifiers that are safe and effective, HEPA air filters are the obvious choice!

HEPA air filters are 100% ozone free while UV, ionic air purifiers, and electrostatic air purifiers will emit ozone to some extent.

Q8. Do Air Purifiers Get Rid of Ozone?

Ozone can be effectively removed by air purifiers with activated carbon filters.
