Answering Frequently Asked Questions About Ozone Generators

 ozone generators decontamination

Since news has come out that ozone generators may be effective in the decontamination process for removing viruses, Airthereal units have been selling out as businesses, medical facilities, transportation services and more are eager to deep clean and disinfect their spaces.

We’ve also been handling a lot of questions about our ozone units regarding how they work, which unit is best for what room, whether ozone can eradicate the COVID-19 virus, etc.. We’re going to tackle some of these topics in this blog and hopefully help alleviate any confusion.

General Use FAQs

mini ozone generator for kitchens and homes

Q: What is ozone and how exactly does an ozone generator work?

A: Ozone (O3) is a powerful sterilizer. When odors, bacteria, viruses or molds meet ozone, oxidation reactions occur and both parties are destroyed. Ozone then reverts back to oxygen. Therefore, even though exposure to high concentrations of ozone can be harmful to humans and pets, it won’t last long in the air. Remember to open doors or windows to allow ventilation for at least 30 minutes after use or turn on the air conditioning during the treatment if you use it in the basement. It can sterilize your AC system as well. 

Note: Ozone can adversely affect indoor plants and damage materials like rubber, electrical wire coatings, fabrics and artwork containing susceptible dyes and pigments. Since the main reaction of ozone is strong oxidation, during the oxidation certain polymer groups may have some negative effects, such as PU plastics oxidizing and turning yellow. 

Q: How do I go about using ozone generators in my cleaning or disinfection process?

A: Step 1 - Clean up first: Before ozone treatments, please do some cleaning in order to remove the source of the odors. Close the windows and doors. Make sure no people, plants or pets are in the room.

Step 2 - Use the timer: It's highly recommended to set the timer and leave it in the room. Treatment time can be adjusted according to room size and air quality. If you aren’t sure, you can start with 15 min and increase the treatment duration or frequency next time.

Step 3 - Use in Unoccupied space ONLY: Exposure to high concentrations of ozone can be harmful. Please stay outside the room being treated with ozone. We include a NO ENTRY sign in the package as a gift, which can be hung outside the door.

Step 4 - Repeat ozone treatments (as needed): You can take out your ozone generator and schedule an ozone treatment whenever necessary. Repeat the previous steps.

Q: Will the unit help with mold reduction?

A: If the mold in question is out in the open, (visible on surfaces)  the ozone generator will kill the visible mold on surfaces as well as spores in the air. After repeated uses of the ozone unit, mold will change color, (gray to white) and you can then clean it off with bleach.

If mold is behind your walls or underneath surfaces, it won’t be exposed to enough ozone to eliminate it. So you would have to remove the non-visible mold in order to eliminate it permanently from your space.

If you can’t easily remove non-visible mold, you will need to use ozone periodically to kill the spores in the air as they form. That should prevent mold from growing elsewhere. If your house is very humid or damp, mold will likely form regularly. In that case, use ozone regularly to kill the spores in the air.

Q: How long do the ozone generator plates last?

A: With proper maintenance, the ozone plate is meant to be used for years (between 5,000 and 20,000 hours of run time). Only change the plate when the blue light is weaker and dimmer than usual and you can’t smell as much ozone as before, post-use. Clean or change the ozone plates if the ozone output is weak. Environmental factors affect the duration of ozone output. Keep the unit in a cool, dry space when in storage.

Q: Can I set my ozone generator to run while I’m gone?

A: Rooms MUST be unoccupied when the ozone generator is on and running. Our units come with helpful, user-friendly timers (some with dials, some without). Timer function can be set up to 120 minutes and you can also use “HOLD” mode to keep it on. Set the timer before you leave the room, ensure that no people or pets are in the room when the ozone machine is working. Treatment times are approximately 10 minutes to 60 minutes depending on the size of space.

Q: Once I have my ozone generator, how do I maintain it and keep it in its best condition?

A: Maintenance is super easy, actually!
1. Take out and wash the pre-filter in the back whenever it gets filled with dust. Reinsert when it’s completely dry.
2. Keep the unit in a cool, dry space when not in use.
3. The ozone plate is meant to be used for 5 years, or 20,000 hours. Only change the plate when the blue light is noticeably weaker than when you first got it (or if only part of the ozone plate is glowing during operation) and you can’t smell as much ozone as before. Ozone plate replacements are available for sale on Amazon and our website.

Q: Does ozone affect plastic?
A: Because of ozone's strong oxidability, plastics exposed to ozone can easily break down and fade. Pollution in the air, extreme heat, chemicals and salts are other known reasons for the breakdown of plastics.

Here are some tips to reduce the risk of damage to plastics:
1. Shorten the treatment time to 10-15 minutes and increase the frequency of treatment. Several shorter treatments will be more effective and less harmful than one long treatment cycle.
2. Remove or cover plastic items during ozone treatment if they can’t be removed from the room.

Q: How do I use an ozone generator in my car or truck?

A: If you’re using a wired unit, use an extension cord connected to a properly grounded wall outlet. . Fully charged portable ozone units, such as the PA50-GO, can simply be placed inside the vehicle and turned on.

Your vehicle’s air conditioning system can accumulate bacteria and dust, so when you ozonate your car, the smell can remain in the system for a while. To combat this we recommend shorter 10-15 minute ozone treatments per session. Turn on the recirculation mode on your vehicle’s AC during treatment and turn on the fresh air mode afterwards, to help with ventilation. Frequent, short-duration ozone treatments are better for removing odors compared to infrequent, long duration treatments.

The rubber, plastic, and upholstery in your vehicle may be oxidized during the treatment. This may cause some parts of your interior to fade or crack. As long as you are performing short-duration treatments, it should cause minimal long-term issues or damage.

Q: How do I use the ozone generator in my basement?

A: Customers have shared that ozone has helped eliminate musty smell and prevent mold and mildew buildup in their basements. Below are some helpful tips for your basement treatment process:

-Eliminate the source of the odor.
-Dry the space using a dehumidifier or by running a fan
-Run the ozone generator in your basement. If possible, turn on your air conditioning system so that the ozone can be sucked into your HVAC ducts to sterilize them at the same time.
-Allow the basement to air out. With open windows, it should take about 30 minutes to air out. If you are unable to open windows in your basement, it may take up to 4 hours for the ozone smell to dissipate and revert back to breathable oxygen.
-If the ozone smell is too strong in the remainder of your house, you may need to temporarily block the HVAC vents in the rooms you are occupying and crack a window to let it air out. Breathing in small amounts of ozone will not have any long-term health effects, but continued exposure might irritate your nose and throat.

Q: Can Airthereal ozone generators kill viruses?

A: Airthereal's ozone generators passed SGS's test that kills more than 99.98% of bacteria. While we cannot definitely say ozone can eradicate the coronavirus on its own, biologists, specialists and other scientists around the world have been working tirelessly, using our ozone generators as a part of their decontamination process. You can read more about it here. We’re continuing to get updates from specialists’ test results in the field and will update our community as necessary. EPA doesn't not recommend for occupied rooms, which is why rooms MUST be unoccupied prior to machines being turned on.

Misc. Customer Questions:

“Is it safe to run an ozone generator in the garage with a gas furnace and water heater running?” Yes, the room must be empty of people and pets but otherwise it’s safe to run indoors around furnaces and water heaters.

Note: Ozone can adversely affect indoor plants and damage materials like rubber, electrical wire coatings, fabrics and artwork containing susceptible dyes and pigments. Since the main reaction of ozone is strong oxidation, during the oxidation certain polymer groups may have some negative effects, such as PU plastics oxidizing and turning yellow. 

“Can a smaller unit run longer to cover a 20×20 room? Can I just open an inside door to dilute, then open an outside window and for how long for each?” Our smallest units can cover spaces up to 330 square feet. For anything larger, we’d recommend one of our larger units. For best guidance on which unit to get by size, please read our Ozone Generator Buying Guide.

“What ozone unit is best for automobile detailing and for the home, office, etc?” For car detailing, a number of our customers tag us in posts, showcasing how they use our ozone units in their detailing process. The most popular model we get tagged in is the MA10K-PRO Ozone Generator, which can sterilize spaces up to 2000 square feet. For best guidance on which unit to get for what space, please read our Ozone Generator Buying Guide.

"Am I allowed to take the PA50-GO on an airplane?" Yes, you can. Except for spare (uninstalled) lithium batteries, all batteries allowed in carry-on baggage are also allowed in checked baggage. However, we recommend that you pack them in your carry-on bag whenever possible. In the cabin, airline flight crews can better monitor conditions and have quicker access to the batteries or device if a fire or leak occurs.

  • I used this to get rid of the stinky smells in my husbands car. He likes to eat in there on lunch breaks. Cheeseburgers, onion rings, sardines in a can. The smell over time became absorbed in the fabrics. One weekend I decided I would clean then car out. It worked.
