How to Choose a Water Ozone Generator: AH1000 vs MA25L & Why Ozone Is Used for Water Treatment
How to Choose a Water Ozone Generator

Ozone technology has been used for decades in water purification, sanitation, and food processing. Today, many households and businesses are also using ozone generators to help treat water, wash produce, and remove unwanted odors.
But what makes ozone so effective, and how do you choose the right ozone generator?
In this guide, we’ll explore why ozone is used in water treatment and food processing, and compare two ozone machines from Airthereal to help you find the best option for your needs.
Why Ozone Is Used in Water Treatment

Ozone (O₃) is a powerful oxidizing gas made up of three oxygen atoms. Because it is highly reactive, ozone can break down a wide range of contaminants when dissolved in water.
For this reason, ozone has been used in municipal water treatment plants, bottled water production, and industrial sanitation systems for many years.
Powerful Oxidation
Ozone works by reacting with contaminants and oxidizing them. This process can help reduce organic compounds, odor-causing molecules, and certain microorganisms in water.
Because ozone reacts quickly, it can improve water freshness and clarity in many applications.
No Chemical Residue
One major advantage of ozone is that it naturally decomposes back into oxygen after treatment.
Unlike some chemical disinfectants, ozone does not leave long-term chemical residues in water, which is why it is commonly used in environments where chemical buildup is undesirable.
Odor Neutralization
Ozone is also highly effective at breaking down odor molecules.
This makes it useful for treating water that has unpleasant smells caused by organic matter or sulfur compounds.
Why Ozone Is Used in Food Processing

Ozone is widely used in food processing and commercial kitchens because it provides a chemical-free sanitation method.
Produce Washing

Ozone-infused water is commonly used to rinse fruits and vegetables. The oxidation process helps break down organic residues and contaminants on the surface of produce.
Many commercial produce washing systems incorporate ozone for this reason.
Food Contact Surface Sanitation
Ozone-treated water can also help maintain cleaner surfaces in food preparation environments.
Because ozone quickly converts back into oxygen, it can support sanitation processes without leaving chemical residues behind.
Odor Control
Food environments often produce strong odors from organic waste. Ozone can help break down odor-causing molecules, making it useful in kitchens and food storage areas.
How to Use Ozone in Water Safely
When using an ozone generator for water applications, it is important to follow safe operating practices.
Here are a few general guidelines:
Use the diffuser stone properly
Ozone must be bubbled through water using ozone-resistant tubing and a diffuser stone to allow proper dissolution.
Limit treatment time
Different applications require different treatment durations. Many ozone generators include timers so you can control the treatment process precisely.
Operate ozone machines in unoccupied areas
Ozone generators should always be used in spaces without people or pets present. After treatment, allow time for the ozone to dissipate before re-entering the area.
Following these practices helps ensure safe and effective ozone use.
