The 5 Best Ozone Generators Reviewed

Ozone Generators

Residential ozone generators produce ozone gas that is effective at killing microorganisms and removing odors (Source).

Many users purchase them to treat tap water, freshen up their laundry closets, cleanse their toothbrushes and dentures, super-wash vegetables and fruits, and remove noxious odors from small areas (Source).

Ozone generators work on odors, in particular, by destroying spores, bacteria, and molecules. Because O3 is an incredibly reactive molecule, it attaches itself to other molecules and chemically changes their structures, which breaks down the odor smell (Source).

O2 Machine Buying Guide

Ozone generators produce ozone gas for the purpose of removing odors and killing of microorganisms. Often times, businesses will use these ozone generating devices to help disinfect hospital clothes, help to deodorize fire-damaged objects, protect against grain-killing insects, as well as a variety of different medical decontamination purposes.

When it comes to consumer applications, ozone generators are frequently used to help with odor removal tasks as well as to enhance the quality of residential air. Some regulatory health bodies advise against the use of ozone generators inside of homes because these health authorities say that they should only be used in carefully monitored and controlled situations inside of occupied spaces.

Using an ozone generator for air cleaning

Chemically, ozone is recognized as a highly unstable gas with the ability to quickly break down into oxygen. Health authorities say that even at its lowest concentrations, ozone can pose a health risk to the respiratory systems of animals and humans. When is applied at higher concentrations, Ozone has the powerful ability to kill fungus, bacteria, molds and other types of unsavory microorganisms.

The conundrum is that for an ozone generator to be effective, it must be used at a high ozone concentration level, which is dangerous for humans to be exposed to- and should only be conducted by a trained service technician.

The two methods of ozone generation

The two methods that ozone generators used to create ozone- the UV-light method or the Corona discharge method. The Corona discharge method works by applying an electrical current to the ozone-generating material, which then charges the air contained inside of the generator and converts it to ozone.

On the other hand, the UV-light method utilizes a special sort of ultraviolet light that produces ozone, and this is generally used to help purify spa and swimming pool water. When users search out an ozone generator for residential use, they are frequently purchasing the corona discharge method of ozone production technology- looking for a quiet but durable unit with a strong warranty.

What are ozone users saying? 

Frequently, users wonder whether ozone disinfection therapy works, how the ozone generating machine functions, and whether it's possible to rent one from a store like Lowe's or Home Depot.

People that have purchased the A2Z Aqua Six ozone generator do have positive things to say about it. One person who suffered from terrible rheumatoid arthritis and was confined to a wheelchair began ozonating water as a means of oxygenating her body.

She says that by treating her drinking water with this ozone generator she began to feel energized, even after her first drink. She says that perhaps it was all psychosomatic, but she swears that she feels more active and alive since she began using the ozone generator in conjunction with a hydrogen peroxide regimen, per the One Minute Cure book.

Another reviewer describes purchasing this ozone generator as a means to help treat chronic Lyme disease, saying that it has been helpful in treating the disease with fewer side effects than traditional antibiotics. He expands by saying that the O3 molecule oxygenates cells and then also uses the free atom to kill funguses and pathogens in the body.

A medical professional that he consulted with says that automated water is effective in killing Borelli, Candida as well as Bartonella, as well as reducing herxing (shorthand for the Jarisch-Herxheimer Reaction, describing when dead or injured bacteria for these and other toxins into the bloodstream and tissues to fast, preventing the body from capably handling it) by reacting with toxins and enabling your body to excrete them more effectively.

Ozone to kill parasites and cancer cells

Yet another buyer who lives in a third-world country where it is essential to disinfect fruits and vegetables prior to consuming them says that this particular ozone generator is a handy portable option as compared to a larger one he installed beneath his kitchen sink. He also recommends that if you were suffering from a stomach ache, you can drink some water while it is ozonated and it will help to kill all the bacteria in your stomach very quickly.

Final thoughts

Indeed, it seems that ozone generators do have beneficial applications whether you are trying to remove a stubborn order from your home, disinfect your foods, or perform robust cleaning of laundry or dental appliances.

Yet, as we have seen, health authorities recommend against breathing in ozone in large quantities. The Food and Drug Administration does not regulate these machines, but there are some guidelines regarding how much O3 it is safe for humans to inhale- with a range between .05 ppm and .1 ppm.

Our advice is to read the product reviews of the residential ozone generators, make sure you understand how they work, and if you are looking to purchase an industrial-strength ozone generator, it may be best left to the professionals to conduct the disinfection service for you rather than risking your health doing it yourself.
