Ozone Generator Buying Guide

Ozone generators are perfect for homeowners and apartment dwellers who are searching for a way to combat rogue odors in their home. These devices are designed to pull carbon-based odors out of the air, and in the process, can kill viruses and bacteria as well. Of course, as is the case with any consumer device, how successfully the ozone generator accomplishes these tasks depends on how well they’re manufactured, so consumers are going to have to do their due diligence when shopping for a model for their home. 

How can you tell a high-quality model from a less-than-stellar model? A sure-fire way is to purchase an ozone generator from our reviews. We took great pain to find and review the best ozone generator models currently available. However, if you would prefer to search for a model yourself, then allow us to at least give you some tips that will make your search a little bit easier. Below is a buyer’s guide that we feel will help our readers find the perfect ozone generator for their home. 

Choose The Right Size

The first step to choosing a great ozone generator is for the consumer to think about the size of the space that is having the air cleaned. If the consumer purchases an ozone generator that is too small for the space being serviced, then it’s not going to do the intended job. These generators always have their area coverage listed, so the consumer should be sure to match the size of the generator with the size of the room. 

Think About Output Strength

Another point for the consumer to think about is the output strength of the unit. Some of the lower quality models can struggle to output 4,000 mg an hour, while some of the higher quality models can easily produce 10,000 mg an hour or more. 

Think About Whether A Timer Is Needed

Another thing for the consumer to think about is whether they need a timer or not. A timer can be a handy feature to find on an ozone generator because the consumer is not going to want to have their machine running all of the time. 

Easy To Replace Filter Or Ozone Plate

It’s also important for the consumer to think about how easy it is to replace the filter on the model. Some ozone generators use filters and some use plates, but despite which one is used, it’s important that it can be easily cleaned or replaced as needed. 

How Portable Is The Unit?

The consumer should also consider the unit’s portability. For some people, the importance of this point depends on how they’re going to use it. If they expect to move the unit from one room to the next, then they’re going to want to make sure it’s portable, but if it’s going to stay in one room, then it’s portability is not as important. 

Consider Additional Features

Of course, the above features aren’t the only ones that the consumer needs to think about. While the above are the basic features, some consumers might want their ozone generators to have some additional features that make it easier to use or allows it to be used for other things. 

  • An Extended Warranty
  • Energy-Star Compliance
  • Built-In Dehumidifier

How To Use An Ozone Generator

Now that we have covered the basics of shopping for an ozone generator, we wanted to pivot and provide our readers with a guide on how to use their new device well so they get the most out of it. Below are some tips and tricks that will help all of our readers get the most out of their brand spanking new ozone generator. 

Ozone Generator Safety Warning

We’re going to begin this guide by telling our readers that they should show these devices with the utmost caution. Although they’re considered to be safe to use for medical and industrial businesses, they can be a bit tricky to be used at home. If strict safety procedures aren’t followed when using these devices, they can pose a risk to human and animal health. That’s because they generate ozone and a high ozone output can affect humans, plants, and animals in indoor environments. They can also cause irritation to the lungs or mucous membranes, and aggravate respiratory conditions. Therefore, they should never be used in the presence of plants, animals, or people.

Follow The Manufacturer Instructions

The next thing that the consumer should do is to read and understand the manufacturer’s instructions before setting up their new ozone generator. As a general rule, most rooms will need 4 to 12 hours of continuous ozone generator use—depending on the size of the room, of course, Treating an entire home might take longer, however, and could take anywhere from 24-32 hours. Just be sure to follow the manufacturer’s instructions and make sure the home is unoccupied while the generator is being used. 

Set The Timer

To make sure that the ozone generator runs for a specified amount of time, it’s important to set a timer. The timer will stop the generator at the appropriate timer so the consumer doesn’t have to wander into the house to turn it off. 

Be Sure To Air Out The Home Before Reentering

It’s also important for the consumer to make sure they give time for the ozone to dissipate back into oxygen before people, pets, or plants are reintroduced to the home. Depending on the ozone concentration in the room or home, ozone usually dissipates anywhere from 45-minutes to 4.5-hours. It’s our recommendation that the consumer gives the room at least 4.5 hours before reentering the home.
