How does ozone work to remove odors?

Ozone (O3) is a potent type of gas with a short life-cycle. When it comes into contact with a contaminant like odor, virus, or bacteria, it eradicates them through oxidation. By doing so, the extra oxygen atom (O3) is consumed, and nothing is left.

That means no bacteria, additional particulates, and odor. What is left is clean and pure oxygen. The ozone gas then reverts to oxygen after its consumption.

Uses of an Ozone generator in a home

You can use an ozone generator at home in many ways. These include:

  • Cleaning the air of dust particles and smoke after a fire.
  • Clearing indoor air of unpleasant mold and mildew odors.
  • Eliminating the smells pets produce at home.
  • Purifying the air in the house.
  • Providing daily air purification treatment in rooms used often by cigarette smokers, places that are musty from neglect like the basement, and rooms that show signs of mold growth.

In general, you can use an ozone generator to remove odors and airborne contaminants from your home and even your car.

What to look for when choosing an Ozone generator

Ozone generators are versatile and have multiple applications. Some units have different price points and correspond to varying quality levels. Of course, an expensive unit does not mean it has better quality than a cheap one.

While many people look at price when buying ozone generators, buy the unit based on functionality, general design, and features. Things to consider when choosing an ozone generator include:

  • Ozone output – How much ozone does the unit deliver? For a single room, the unit should deliver 240mg of ozone per hour. For a house less than 1,000 square feet, choose one that can produce 400mg per hour. If your home is more than 2,000 square feet, buy a generator that has an output of 800mg per hour.
  • Size – Some ozone generators are big others are small. Choose a size that is convenient for you or one you can quickly move from one area to another.
  • Maintenance – Choose an ozone generator that is easy to maintain and clean. The cost of maintaining the unit and replacing broken or defunct pieces should be low too.
  • Unit housing – Many ozone generators have stainless steel housing. But choose durable housing for your unit.

Always look at ozone generator ratings before purchasing the unit. Also, consider a warranty and money-back guarantee when buying an ozone generator.

How to use an ozone generator in a home

The best ozone generator reviews would suggest that you exercise safety when using the unit at home. First, ozone is a highly reactive type of gas and can be dangerous to your respiratory system if inhaled. When using the ozone generator:

  • Always use it in an unoccupied space – You should not be near your ozone generator when the unit is in operation. It will produce ozone that is toxic to the lungs, sinuses, and air passage.
  • Use a timer to operate the machine – Ozone generators come with timers. A timer will activate the unit and ensure it runs for a set number of hours. Do not run it for prolonged hours as ozone will harm your home.
  • Allow the unit time to operate – It should work for at least one hour before shutting off. However, this will depend on your room size or treatment area.
  • Wait for ozone to settle and revert to oxygen – It will take at least 2 hours for the air in your room to become normal oxygen.

Ozone is a dangerous type of gas, but it is the best thing you can use at home to kill bacteria and remove odors. Always protect yourself when using it. Before using it, read the instruction manual first.

Residential ozone generators produce ozone gas which helps to remove odors and kill microorganisms. You can use the best ozone generator for home use to do many things. For example, you can freshen up your laundry closets, treat tap water, and remove odors from basements.
