Best Ozone Generators

Ozone generators are used for protection against harmful ultraviolet rays (UV) from the sun. They protect your skin from damage caused by UV radiation, which causes wrinkling and aging of the skin. You may think that it’s not necessary to use an ozone generator when going outdoors, but there are certain situations where using one is essential. For example, if you’re working in a room with high levels of UV radiation or if you plan to go swimming in the ocean.

There are two types of ozone generators: solar and chemical. Solar generators generate their own power; they don’t need any external source of energy such as batteries or fuel. Chemical ozone generators require chemicals to produce oxygen, so they must be kept away from sources of pollution like gasoline stations and other combustible materials.

Solar Ozone Generators

The most common type of ozone generator is the solar ozone generator. These devices work by converting sunlight into electricity. A typical solar ozone generator consists of a small photovoltaic panel on top of a metal housing.

When the sun shines on the device, it converts some of its energy into electricity that powers an electric motor inside the unit. The motor turns a fan, which forces air through a tube filled with a special chemical called titanium dioxide (TiO2). The fan is usually placed at the bottom of the housing and blows air up through the generator.

Titanium dioxide is a chemical that reacts with sunlight to produce ozone. As the motor forces air through the tube, it also forces the chemical through small holes in the tube. Once in contact with air, a chemical reaction occurs that releases ozone.

The fan forces the ozone out of the tube, through a vent, and into the surrounding area.

Solar generators are convenient because they don’t require any maintenance and are powered by an unlimited energy source (the sun). They’re perfect for emergency use, like during a flood or power outage. They’re also good for outdoor activities like hiking or camping.

Just connect one to a small battery or a car battery to get it started. For maximum efficiency, place it in direct sunlight.

Chemical Ozone Generators

Chemical ozone generators use an electrical current to break down a chemical, releasing ozone. The most common chemicals used are hydrogen peroxide (H2O2) and acetone (C3H6O).These generators come in two main types: contact and non-contact.

Non-Contact Generators

Non-contact generators use chemicals dissolved in water to produce oxygen gas. They’re cheaper than contact generators, but they require a power source.

Hydrogen Peroxide

Hydrogen peroxide (H2O2) is commonly used in medicine and as a disinfectant. It can be fatal if swallowed, causes burns if it comes into contact with skin, and is corrosive to eyes and skin. In an oxygen concentrator, it produces ozone with medical-grade purity.

Acetone

This is another chemical that can be fatal if swallowed. It’s colorless and has a sweet smell. It’s commonly found in nail polish remover.

Like hydrogen peroxide, it produces ozone of medical-grade purity when used in an oxygen concentrator.

Contact Generators

Called direct contact generators, these devices have no water to dispose of and are cheaper than non-contact generators. The disadvantage is that they require you to place your face over the opening, so you need to use them in a well-ventilated area. They’re also not as efficient as non-contact generators.

Aerosol Cans

In an aerosol can, a mixture of oxygen and nitrogen is compressed and mixed with a harmless propellant like propane or freon. When you open the can, the pressure caused by the expansion of the compressed gases forces the contents out of a small opening at the top. The gas and liquid mixture quickly converts to ozone and water in the air.

How It’s Measured

Ozone generators are typically rated in multiple different ways. The most common is in O3, which stands for “Oxygen Standard Form,” but is also called .088 and sometimes referred to as “OC.”

They’re also rated by the size of the area they’re able to treat. The standard measurement for this is a “sqaure foot,” but it’s not actually a square; it’s a cube. If you were standing on one corner of the cube and measuring out an 8×8 square, that would be a 1-foot cube.

So, 7 cubes long and 7 cubes wide would equal 49 cubic feet.

This is a lot of numbers to keep track of, so manufacturers simplify it for the consumer by using the following ranking system:

Best Ozone Generators - Picture

Nanozone: Can treat .08-.1 sf

Pallzone: Can treat .2-.3 sf

Microzone: Can treat .4-1 sf

The most important thing to keep in mind is that these are guidelines. In other words, your 1000 square foot home may be able to run a 1000 square foot O3 machine under ideal conditions. But if you’re using the machine in a very large area, like a warehouse, or in a basement where the water drainage is poor, it may not perform up to its full potential.

In that case, you might need a higher-capacity machine.

Conversely, if you’re using an O3 machine in a very small space such as a 1-bedroom apartment, it may be able to run a 2000 square foot machine. It all depends on the conditions. As always, it’s best to consult the manufacturer’s guidelines.

Where Can I Get an Ozone Generator?

Most companies that sell ozone generators will also sell you replacement canisters. If you’re looking for a specific brand, you may be able to find one on eBay or Amazon. The only problem is, it’s possible the device has been discontinued and you won’t be able to get a replacement.

If you want a particular machine, but you’re concerned about getting replacement filters or canisters, buy two so you have a backup.

How Do I Use an Ozone Generator?

Place the machine in the room where you want to use it and turn it on. You’ll need to experiment with placement to determine where it works best. In some cases, it may be more beneficial to place it in one part of the room and then move around the rest of the furniture.

Ideally, an ozone generator should be at least three feet from any heat or electricity sources. This includes items such as televisions, speakers, lamps, windows that open, doorways and ceiling beams. It’s also important not to place them too close to walls.

This allows air to circulate and increase the efficiency.
