The Complete Guide to Using Ozone Generators Safely

An ozone generator is one of the most powerful air purifiers that you can own. Whether you use an ozone generator in the home, in the car, or even in the basement, it will help. Most people use ozone generators to remove odors, but they can also be used to kill mold, remove smoke and cigarette smells, and even bacteria and viruses. However, you have to know how to use an ozone generator safely.

If you have more than a musty smell from mold, you’ll likely need a commercial grade ozone generator.

It is possible to use an ozone generator in the home. There are many people out there that tell you not to use it, but most don’t know how to use it. It can be dangerous, but the dangers of ozone generators can be avoided. This article will tell you how to avoid the dangers of ozone generators, how to properly use an ozone generator, and how long to use an ozone generator.

There are many things that you can do to keep yourself from getting sick or interacting with ozone. Sealing the room or car off is an important factor, considering ozone needs to be contained. When ozone is pumped through the room, the chemical makeup of ozone will latch onto and destroy anything that might come into contact with it. This includes killing mold, odors, and bacteria.

What is Ozone?

Ozone is a chemical where oxygen molecules become imbued with three oxygen molecules instead of two. A normal oxygen molecule has two O molecules, which is the “O2” you might see listed on something. Whenever ozone is made, this “O2” becomes “O3”, meaning three oxygen molecules are combined into one. Ozone is dangerous to humans and other organic things, considering it can mess with our own chemical makeup.

However, eventually, ozone will fizzle out. This means that the oxygen molecules will eventually weaken and detach. The ozone molecule becomes a normal oxygen molecule once more. Over a small amount of time, a room filled with ozone will eventually be enterable again with breathable atmosphere. Ozone becomes normal oxygen.

Did you know that you can smell when rain is coming? You might notice a strange, humid scent that comes with the wind or after it has rained. This wind actually has ozone in it. You might be able to equate this to a hotel room when you first walk in. Even they use ozone generators to clean rooms sometimes!

Since there is such a small amount of molecules of ozone, it’s not usually dangerous to humans. However, this is where the air quality index from the environmental protection agency comes from. It’s wise to check the air quality from your local weather forecast, especially if you have breathing disabilities like asthma or other lung diseases.

How dangerous are Ozone Generators?

Since our bodies are made up of similar chemical properties, ozone can have quite an effect on us. While it won’t do very much to your skin, your sensitive organs on the inside can fall victim to ozone damage. This is especially true if you have some sort of breathing problems like asthma or other lung diseases. Children are also susceptible to ozone, considering their lungs are still growing.

Some healthy people can have problems with ozone as well. They may have a higher sensitivity due to genetics or other factors. If you or your child has asthma problems or anything like chronic bronchitis or emphysema, you may want to stay away from ozone generators altogether.  They work extremely well, but sometimes it’s not worth the risk. However, if you still want to, be sure to read the following information.

Fortunately, if you’ve been involved with ozone, your body can heal from it. It might take some time, though. Inflammation of any organ is never fun and can be very painful, so always know the risks before doing anything with ozone generators. They are practically unmatched when cleaning your air, but it kind of “bleaches” it too. Bleach is harmful to us, so use it responsibly.

Good Up High, Bad Nearby

Now, you might be thinking that you’ve heard of things called the “ozone layer” and such when dealing with ozone. Ozone can be very good for humans, but only because it’s “up high”. The Environmental Protection Agency has given us the phrase of “good up high, bad nearby”. This phrase means exactly what it says—ozone is good up in the air, considering it blocks out the harmful ultraviolet rays from the sun and other harmful gasses outside the atmosphere.

The bad kind is when it’s around us, along the ground or in our homes. You should never try to breathe in ozone directly, considering of the warnings above. It will harm your lungs and cause a lot of respiratory problems even if you don’t have asthma or any other lung disease. Keep in mind that it can also damage things like crops and vegetables, so make sure your ozone generator is in a secured area.

How does Ozone eliminate odors?

Similarly to how they are dangerous to humans, ozone molecules are dangerous to particles of smoke, bacteria, and mold. Since ozone molecules are highly reactive to the things they come into contact with, molecules of smoke, bacteria, and spores will be bound to. Because of this, it will either eliminate the spores of mold or bacteria and the smoke molecules by changing them into something different.

Ozone can get into anything, considering it’s all gas. Gasses can get into cracks and crevices, walls, air conditioning ducts, carpets, and more. Because of this, it will get into those really small pockets that can house those offensive odors. While it can be dangerous to use, it can be more helpful than almost anything else you can find.

Picking the Best Ozone Generator

The best ozone generator is subjective on many factors. There are quite a few of them out there and they do a lot of different things. Price depends on the size of the ozone generator, but most of them can cover a room or the size of a car in a few moments. It’s a good idea to measure the size of your room or the rooms that you want to clean.

Different sizes of the rooms mean different sizes of the ozone generators. There are some generators that can go through the whole house, but those aren’t usually available to non-professional consumers. Many professionals can use an ozone generator to go through your entire house, but this has to be set up, considering you’ll have to vacate the area before-hand.

There are a lot of different options when it comes to ozone generators. Plenty of ozone generator buyer’s guides are out there, including the one we have. Many manufacturers offer different features, like timers, switch methods, room coverage, and more. The best thing to do is assess the area or home where you want to clean the air and go from there.

orlando mold remediationKilling Mold with Ozone Generators

Mold is a terrible thing for your home to have. It’s hard to get rid of, smells bad, and can even make you sick. These surfaces of fungi will produce many spores that we inhale. Whenever we take them into our bodies, it can cause a lot of problems. Respiratory problems are a common occurrence whenever mold is present. It can cause shortness of breath, coughing, and wheezing. That’s not all, of course.

People who are sensitive to mold can suffer from a lot more than that, though. They can get headaches, fatigue, and could even suffer from bad inflammation that can cause a lot more problems. Considering that fungi are organic things, they are also under the same rules as any other for ozone. That means that it is also harmed by ozone, binding with the spores in the air and slowly changing them into something different, destroying them completely.

Professional mold cleaners and removers use ozone generators to kill mold. Remedial services rarely go without at least one ozone treatment, so don’t be surprised if they ask you to vacate the home for a while. Ozone is effective for killing mold, considering the spores are eliminated and doesn’t give it a chance to spread further through the home.

Kill Pests with Ozone Generators

Even though people may not enjoy the thought of them, bugs and insects are all around us. There can be roaches, spiders, and other creepy crawlers that annoy us or even scare us. Some people may have a bigger problem than others, though. People may have a mouse problem as well, so an ozone treatment may be your best bet.

Keep in mind that you may need a professional to get pests out of your home. This is because insects and pests run away from danger. When they sense the ozone, their instincts tell them to run away, so they may leave and then come back into the house. It could take a more powerful ozone generator to do this so you can “shock” the home with the ozone. This means that it will fill the home so fast and quickly with a large amount of ozone that the pests can’t get away.

Many professional pest control companies employ ozone generators for pests. This isn’t the only option, of course. There are similar ways, like bug bombs and foggers, that will assist in this. However, these methods can be rather dangerous considering they contain pesticide and other harmful things. Covering your belongings and possessions is a necessity when using a bug bomb.

Ozone Generators in the Home

There are many ozone generators out there, and some even come with multiple types of filters. Some of the ozone generators are also imbued with ionizers, which pull in particles and eliminate them by zapping them and deconstructing them. However, using ozone will simply bind to the offending particles that are causing the smells and simply eliminate them. Using ozone generators in the home is useful, but read the safety precautions!

  • Locate the offending cause of odor if there is one.

Odors can be made by anything. Humans, animals, smoking, or even the atmosphere itself can carry strong smells. A wet dog can cause this very unique odor to sink into furniture or carpeting if you don’t clean them before they get on things. This smell can persist and last a long time. If you take good care of your home and don’t smoke, odors can be kept at bay. However, smoke can be carried indoors and can be very difficult to remove. Find a way to stop the source first.

  • Use what you can to remove the odor first.

There are a lot of products out there that can assist with the removal of odors. Things like Fresh Wave and Febreeze are excellent at taking odors from the air. Using these before setting up the Ozone generator will provide better results. Considering that Ozone generators are not some sort of end-all, be-all device, it will help a lot in the long run.

Spray the affected areas and try to clean as much as you can. This will lead to a better result when using the Ozone generator. These sprays that are specifically used to remove odors may not remove the entirety of the odor, however. It is a good idea to get rid of much of it as you can before you move to the ozone generator. Keeping the area clean is a good idea regardless, but make sure to be thorough.

  • Go over your safety precautions and manual.

As it has been said many times through this guide, ozone is dangerous to living things. While humans do fall under this, it also affects animals and plants as well. It doesn’t matter what it is, all organic things will be bothered by this. If you’re going to run an ozone generator in a solitary room, make sure it is sealed off from the other rooms. Usually, this means putting a towel or tape along the bottom of the door and covering the vents.

You should also remove any plants or pets that you may have in this room. There should be nothing living in this room for the time being. If you’re doing the entire house, you should not be in at all. Vacate the area, along with your pets and plants. Considering how long you have to do it, you will likely have to find another area of residence for the time being. A hotel or family member’s home are good options, of course.

  • Determine how much time you need to run it.

When it comes to ozone generators, there are a few options that you have. Normally, the recommended time for an ozone generator to run is 3-6 hours. Of course, this will have to be longer if you have multiple rooms that you want to clean. Ozone is heavier than normal oxygen, so you should set it up in the second floor if you have multiple floors.

A good way to spread it through the home a bit more is to let the air conditioner or vents to pull up the ozone and distribute it through the home. That is, if you’re doing the entire house. If it’s only a room, then you should seal off any vents as said above. Doing an entire home should last about 26-30 hours to fully deodorize a home.

  • If your ozone generator has a timer, use it.

Most modern ozone generators, both in business and personal use, have timers. They usually are able to run from 20 minutes all the way up to 8 or 10 hours, depending on the manufacturer. Using these timers will allow you peace of mind, since you won’t have to go back into the room to turn it off. Another option is to get an automatic switch to connect to the ozone generator, which you could control outside of the room.

If you have to stop it or if it doesn’t have a timer for some reason, use extreme caution when entering the room again. Hold a towel over your mouth and nose and hold your breath, considering the ozone can cause damage if you breathe it in. Shut the ozone generator off and quickly leave the room and wait for a while before going back in.

  • Wait before going back in.

You don’t have to have another special tool to remove ozone from your room. Fortunately, ozone settles after a 2-3 hours and the molecules detach to become regular oxygen again. This oxygen is safe to breathe. After it breaks down, it becomes safe to go into the room. The machine should already be off, but if it’s not, follow the above steps to do so.

Again, never breathe in the air if there is still ozone in it. It can damage your lungs and irritate your throat. Ozone can also give you a headache and other breathing problems, so be sure that the machine is off and that it has time to settle. There may be scent of ozone that still exists, but it will still be fine. It will smell just like it does after a rainstorm.

This is the best way that you can clean the odors in a home or room. This also works for any apartment as well, considering it is a bigger room rather than a home itself. However, you should be sure that everything is sealed, considering there may be some connections from your apartment to a neighbor’s. This includes vents and other things. Make sure that your landlord is alright with you doing this, first!

Ozone Generators in the Car

Vehicles can get some pretty funky smells over time. One might spend a lot of time in their vehicle, especially if they travel a lot. This is also true if you or someone in your family is a smoker, has pets that ride a long, or anything that might produce smells. Since vehicle interiors are usually absorbent, they will contain any liquids or other scent-producing things.

After things get settled into the material, it can be difficult to get out. These smells and stains can be removed, but the steps are similar to the ones above. You can use an ozone generator in the car, but there are certain sizes you’ll need to use to be effective. Of course, a bigger home-generator will work fine, but a room-sized ozone generator will be fine.

  • Remove the source of the odor.

Similarly to the room and home processes, you should find out where the smell is coming from. Whether it’s a stain or because of a smoker, this can be easily taken care of. There’s not much room in a car as opposed to a house, so it may be easier to locate the scent. Regardless, find it and do what you do with stains and other offending items.

Using similar cleaning items like you may have done for your home, do the same for the stains or odors for your car. Using Febreeze or some other odor removing liquids, do what you can for the scent that’s already there. Spraying it into your cushions and interior material will alleviate quite a bit of the smell, considering it eliminates the particles itself.

  • Remember the safety precautions and be sure to read the instruction manual of the ozone generator.

Stated once more, this is one of the most important steps. Go over your safety precautions and make sure you’re not in the car when the ozone generator is on. Of course, you shouldn’t have any pets in there either, but it’s good to state regardless. After you’re sure that everything is in order, then prepare the ozone generator itself.

It’s a good idea to remove any sort of objects you might have in the car. Remove any trash, books, papers, and other such things out of your car to get to the deepest parts of it. Ozone doesn’t interact well with too many items and can cause discoloration, including the spare tire in the back if the trunk area is connected.

  • Place the ozone generator somewhere it won’t fall over.

An ozone generator has to pull in oxygen and pump it out, so make sure both ends of the generator are uncovered. Placing it on a wide armrest or in the center of the back seats could be optimal. Make sure it doesn’t fall over because that could cause a fire hazard and decrease the effectiveness of the machine itself.

However, some ozone generators come with hoses, so you can place it on the ground outside. A dryer duct works too. Push the hose through the window and raise it up as much as you can. Afterward, put up some sort of barrier to the rest of the window. Cardboard and tape works fine, so be sure to cut out the shape of your window and tape it up. Turning it on can be done from the outside as well, so make sure that the window is all sealed up.

  • Run the generator for about 45 minutes, but don’t go longer than two hours.

Since cars are smaller than the room in a house, it won’t take as long to get through. About 45 minutes is a good idea, but can be as little as 30 minutes if you need to get somewhere. Ozone will fill the car, so do not enter it before it is done. After that time has passed, turn the ozone generator off and let the ozone settle for about an hour or two.

After the time has been waited, you can take the ozone generator out of the car or window and open the doors to air it out. It shouldn’t take too long, but it will smell like a brand new car after all is said and done. It will have all the odors removed, but you may have to run it a second time after a little while. Make sure you don’t go for more than two hours, though!

Ozone Generator for the Pool

One of the more annoying things about pools is that they need to be cleaned. They need to be cleaned often. There are a lot of different chemicals to use in a pool, including chlorine tablets and different acids. However, you can also use an ozone generator for cleaning it as well. While it won’t be as efficient as chemicals to specifically clean your pool, it can be a good idea to do.

If you or someone is very sensitive to chlorine or other pool chemicals, ozone is a great alternative. It purifies the water and kills bacteria and viruses. Remember that ozone can still harm you if you breathe it in, but in the water, it’s practically harmless. You won’t be breathing in the water, after all. It’s still a good idea to stay out while you’re running it, though.

While ozone is quite strong, you may still need to use a bit of chlorine to further clean your pool. It is a strong chemical and can make your water stink for a bit, but there is hardly anything better. However, it’s not very necessary if you keep your pool clean enough. Constant maintenance is needed, but you can keep the chlorine out if you use the ozone generator often enough.

There are specific types of ozone generators for pools. These need to be installed by a professional, though. They have to be put underground if it’s an in-ground pool, but a long hose can help. An above ground pool can be treated easily with a home ozone generator, but it must have a secure hose around it to put into the pool.

Ozone Generator for Hunting

Hunting is an American pastime and can be fun to do. However, there are certain things that you have to keep in mind when hunting. Animals are very intelligent and flighty, especially when it comes to hunting time. It’s almost like they know we’re around. These animals function a lot by scent and smelling a predator nearby can save their life.

Ozone generators can help with hunting by sterilizing and taking all the scents off your clothes and equipment. Whenever this is used, the animals you’re hunting won’t be able to smell you very easily. It’s not as difficult as a room or house, but it still carries the same dangers as breathing in ozone. There are a few things you need to do to clean your equipment with ozone.

There are quite a few portable examples of ozone generators that can work well enough for a quick douse on your clothes, but don’t breathe it in. Breathing it is still just as dangerous, no matter how small the generator. Make sure that you’re not in the same location as the ozone generator. You can hang your clothes and equipment up and let the ozone do its thing.

Some have stated that it helps a lot with hunting. Not only are you hidden from the animals, some even become curious about the strange smell. While it’s pretty much natural, there have been reports of people seeing deer stick around longer than normal. The smell is natural after a rainstorm, so deer and other prey might move closer toward the smell, thinking it’s safe to approach.

Renting an Ozone Generator

Ozone generators can be pretty expensive, but there are ways to obtain one without forking over a lot of money. Of course, it’s not entirely as useful as buying an ozone generator yourself, it can save you some money in the long run. There are multiple areas where you can rent an ozone generator, but you have to count on it working as it should.

This is a good way to try out an ozone generator you want to purchase, though. If you’re afraid of commitment, rent one first! It can show you just how easy it is to use, but be sure to read all the precautions first. Each one should come with an instruction manual, so read through it before using it. Make sure you practice all the safety guidelines as well.

Many rentable ozone generators can be from a small size to even industrial-sized ones. The latter is going to be a lot more expensive, but consider getting a professional to do it for you. That way, you don’t have to rent anything at all and can still accomplish what you’re setting out to do. A professional will know exactly what to do and how to use an ozone generator. They’ll also bring their own and it will likely be a lot more powerful than the average ozone generator!


Odors and foul smells will always be a plague when it comes to our homes. Whether it’s one room, the entire house, or your car, ozone generators will help you with these things. An ozone generator pulls oxygen through itself, connecting an additional molecule to create an oxygen molecule with three molecules, or O3 instead of O2. This ozone is what covers our earth to protect us from harmful sun rays that can damage our skin.

Ozone, however, is dangerous to the human respiratory system. If inhaled, ozone will cause itchy, scratchy sensations along your throat. It can also cause inflammation in your lungs, cause headaches, and more. Those with asthma and other lung diseases can experience worsening symptoms when around ozone. Air quality is crucial, so be sure to take a look at your local weather forecast for the air quality index report.

There are so many ways that you can use an ozone generator. You can use it in your home, in your car, in your pool, and even on your hunting gear. There can be a lot of other things, too, but these are the most common areas. It helps with things like pollen and other allergens as well, so be sure to use it whenever necessary. Be safe, though! Remember, ozone is dangerous for human breathing.

If you don’t want to purchase one or want to try it out, think about renting one or hire a professional. There are plenty of remedial and odor-removing services out there. Most of them use ozone generators, so don’t be afraid to call and schedule a quote for your home. You may need to line up a place to stay, though. It could take a day or two for them to completely clean your home. It’s a great way to restore your home and make it feel brand new!
