Enerzen Ozone Generator Review (O-555 / O-777)

Whether you need a deodorizer to remove toxic fumes from warehouses or odors from your kitchen and pets, an ozone generator is the best tool to have on hand. Today, we’re looking at the Enerzen O-555 (white) and O-777 (black) models, a heavy-duty, industrial-grade ozone generator that sterilizes odors, leaving fresh, breathable air after just a few hours.

6,000-mg Ozone Output

These Enerzen ozone generators are rated to have a maximum ozone output of 6,000 mg per hour, which is much higher than what you might expect from such an affordable model.

However, on average, these generators produce a maximum of around 4,500 mg per hour at about 14.3 ppm, which isn’t bad for such a compact device. The output can fluctuate between 4,100 and 4,200 mg at times, but even for heavy-duty deodorizing jobs—e.g., fire and flood restoration—these ozone generators can work like a charm.

1,250-Square-Foot Coverage

When shopping for an ozone generator, it’s also important to determine how far the generator can reach. These Enerzen models have a maximum reach of about 1,250 square feet without walls or partitions.

That’s large enough to cover around one-third of a home or an entire basement. We’d like to point out that Enerzen’s ozone generators cost close to nothing, which is one of their major selling points. So, purchasing more than one generator per home isn’t unheard of.

Self-Regulating Timer

Ozone is considered to be the “bleach” of air quality control, but it’s also an extremely hazardous substance that can wreak havoc on your lungs. To keep ozone production within controllable levels, you should make use of the Enerzen’s built-in timer function, which you can set to 3 hours on max.

After the timer has expired, wait between one and two hours for the ozone to dissipate before cracking a window and waiting for an additional hour.

Did you Know

That many air pollutants can damage the skin, including ozone, hydrocarbons (like VOCs and PAHs), oxides (like nitrogen oxides and sulfur oxides), and particulate matter.


Continuous Output Setting

Alternatively, for homes, offices, or warehouses with incredibly foul odors, you can deactivate the timer function and set it to continuous output mode.

This allows the Enerzen to run continuously until someone manually kills the motor. Based on user reports, some people have allowed their Enerzens to run for 12 hours at a time without the slightest hint of trouble. The built-in heat sinks do an excellent job at removing heat, allowing the motor and fan to run for extensive periods nonstop.

Washable Stainless-Steel Filter

As you might expect from an ozone generator, these Enerzen models don’t come with any fancy filters. Instead, it has a washable stainless-steel filter that traps most large particles from making their way past the fan and out of the exhaust.

Make sure you keep a close eye on the filter and wipe it clean of accumulated debris frequently.
