Rainbowair Activator 250 Series II — Professional Ozone Generator for Areas Up to 2,500 Sq Ft
The Rainbowair Activator line has been the go-to ozone generator for property restoration professionals for decades. The 250 Series II is the entry point: 2,500 mg/hr of ozone output, built on the same industrial chassis as the larger Activator models, and proven across thousands of restoration, hospitality, and property management deployments.
Where cheaper units fail — inconsistent output, plates that corrode in months, timers that fail mid-treatment — the Activator 250 keeps running shift after shift. That reliability isn't accidental. The Series II design uses ceramic ozone plates with aluminum construction, the same bill of materials as the Activator 1000 and 2000.
Corona Discharge Ozone at Commercial Scale
The Activator 250 uses high-voltage corona discharge to split O₂ molecules and produce ozone at a consistent 2,500 mg/hr rate. The ozone disperses through the treatment space, oxidizing and destroying odor compounds — smoke, pet, mildew, chemicals — embedded in surfaces, fabrics, HVAC systems, and wall cavities. Unlike enzyme treatments or deodorizers, ozone reaches areas you can't physically clean.
Treatment requires unoccupied space. Clear the area of people, pets, and houseplants before operation. Ventilate fully before re-entry.

Located in the Twin Cities in Minnesota, we acquired our Brio Air Filter in mid-late Spring of this year (2023) when pollen count was high and we were beginning to experience the effects of Poor Air Quality Index as a result of smoke particulates from fires in Canada that caused the air in much of Minnesota to become hazy and simply dirty.
It is so easy to share our experience with the Brio Air Filter given how quickly and efficiently it removed pollen, dust, and smoke particles from the environment inside our home. Two people in our home who suffer from pollen-related allergies during the spring immediately experienced easier breathing and elimination of symptoms within the house. With respect to smoke particulates from Canada drifting into our environment, EVERYONE in our home experienced directly improved breathing and smell of the air when entering from outside.
An additional piece of information to account for is that we have always employed high grade furnace filters in our home’s central HVAC system. With that high grade filtration in place both prior to and after acquiring a Brio home air filter, we all quickly agreed that deploying the Brio in our home made an easily noticeable positive difference in breathing inside our home. Additionally, those of us who clean our home have observed that dust builds up slower on our floors and furniture than before we deployed the Brio unit.
We did note that the Brio is not as quiet as a few other brands/models on the market that we have tried in our home but the efficiency and quality of the filtration, along with the air turnover rate it provides,allows us to locate the Brio unit in central rooms away from the bedrooms. Since we made that change there has been no noise-related effect on our sleep, while the unit maintains the same level of air cleanliness throughout our home.
A last key point to make is how easy the Brio unit is to maintain. The simplicity of the modular construction of the Brio unit makes it very quick and easy to keep the filtration sections clean. We have not yet reached a point of filter replacement but it is obvious to us that the replacement will take a matter of seconds and can be executed by anyone in our home, including our 10-year-old son.
It seems to help reduce my allergy issues. We're glad we bought it. The only problem I had was not seeing any cubic footage recommendations in the online description when purchasing the unit. Bedrooms vary widely in size!!
