What is an Ozone Free Air Purifier, and what is the best one out there?

An air purifier cleans the air in your home or office and improving your air quality. Pet dander and hair, dust, and even food odors can be unpleasant, and  Ozone Free Air Purifiers will clean all these and more out of your air, without adding additional Ozone.

That’s right, some air purifiers actually make ozone, which when you think about it is really counterproductive. Ozone can actually be just as bad for you as cigarettes. If you don’t let people smoke cigarettes around you, why would you want an ozone generator masked as an air purifier around you?  There are a lot of different kinds of air purifiers, and they are not all healthy. Some are even ozone generators, which is why it is so important to find a purifier for your home or office that reduces your ozone exposure.

Why Go Ozone Free?   

Why Ozone free though? Aren’t filters enough? No, filters alone do not reduce your ozone exposure. Ozone can hurt your lungs and cause other issues, so using an Ozone Free Air Purifier creates a positive health benefit by cleaning your air for anyone that enters the room, without adding additional pollutants. Air purifiers with true HEPA are your best protection against air pollution to give you the best air possible.

Ways To Improve Air Quality

There are several different types of air purifiers. Electronic air filters use an electronic method such as UV light, ionizers, plasma, PCO, ESP, and a few others. This is the category that the air purifiers that actually create ozone fall into. Generators and ionizers are the highest ozone-producing purifiers that are out there. Mechanical air purifiers use charcoal or HEPA filters and there are also hybrid units out there that use a little of both methods.

People Also Ask

Can Air Purifiers Remove Ozone?

It honestly depends on the air purifier. Ozone is a gas, not a particle. Air purifiers that use ozone generators or ionizers do not remove ozone; they actually produce it. However, an air purifier with an activated carbon filter will. Currently, the activated carbon filter is the ONLY way to filter ozone out of your air.  If you are in California, the California air resources board has strict quality control and requirements on this. The California air resources board recommends purifiers that do not produce additional ozone such as ionizers and recommends purifiers that can help to reduce the existing ozone.

Are Honeywell Air Purifiers Ozone Free?

According to the manufacturer website, Honeywell home air purifiers are ozone free and use HEPA filters. However, the Honeywell electronic cleaner does produce a trace amount of ozone. Your best bet is to make sure you get one of the Honeywell air purifiers, not a Honeywell cleaner. Purify, don’t clean.

Do Holmes Air Purifiers Produce Ozone?

Holmes air purifiers offer true HEPA protection, some with a carbon filter. The Holmes air purifiers with true HEPA  filters will not produce ozone, but they won’t reduce existing ozone from your air either. The Holmes models with a carbon filter and true HEPA  will reduce some existing ozone, as well as not produce any further pollution.

Let’s Recap

Researching air purifiers can be daunting but worth it because finding the best air purifier will give you the peace of mind that the air in your home is fresh and clean. You should look for one of the ozone-free air purifiers that comes with a HEPA filter, specifically a true HEPA filter. In addition, a carbon filter (or activated carbon filter)  in conjunction with a true HEPA filter will give you even better results than just getting an expensive filter for your HVAC system that will not offer the same benefits as purifiers.
