Rainbowair Activator Ozone Generators — Professional Odor Control for Restoration and Property Management
Four Activator Models: 250 to 2,000 mg/hr for 2,500 to 20,000 Sq Ft
Every Rainbowair Activator uses corona discharge technology — ambient air passes through the unit, O₂ splits into O₃, and ozone disperses as a gas through the entire space to oxidize odor compounds, mold spores, and bacteria at the molecular level. Output and coverage scale with the model. The Activator 250 Series II runs at 250 mg/hr for rooms and rentals up to 2,500 sq ft. The 500 Series II doubles that for suites and small commercial spaces up to 5,000 sq ft. The Activator 1000 Series II delivers 1,000 mg/hr across 10,000 sq ft — the model restoration contractors carry on fire and smoke jobs. The 2000 Series II tops the lineup at 2,000 mg/hr for 20,000 sq ft, with dual 206 CFM fans for rapid penetration of large structures in high-humidity post-flood environments. All four models carry a 5-year manufacturer warranty and a 10–15 year life expectancy. Made in the USA by Queenaire Technologies.
How Restoration Contractors Deploy Rainbowair on Fire, Smoke, and Water Damage Jobs
Ozone reaches where surface cleaning cannot — into HVAC ductwork, subfloor cavities, wall voids, and upholstery. Restoration professionals run the Activator 1000 and 2000 on fire, smoke, and biohazard jobs after affected materials are removed and the structure is sealed. The built-in timer allows safe, unattended treatment: set the unit, leave the space, and return after the ozone dissipates. Auto detailers use the Activator 1000 Single Auto Kit to pipe ozone directly into vehicle interiors — the hose-and-flange accessory keeps the generator outside while ozone treats the entire cabin. Property managers run the 250 and 500 during apartment and hotel turnovers using the 60-minute timer, making treatment repeatable without any technical involvement from cleaning staff. The IICRC recognizes ozone as one of the most effective tools for professional malodor elimination in unoccupied spaces when applied at correct concentrations.

Warranty, Auto Kits, and Service Kits: What to Budget for Long-Term Ownership
The 5-year warranty covers the Activator unit itself. Ozone output depends on the ceramic dielectric plates inside the corona discharge assembly, which degrade with use and require replacement every 6 months under normal operating conditions. Rainbowair maintenance kits bundle replacement plates, Sporax antimicrobial filters, fuses, and alcohol wipes in a single SKU matched to each model: one kit covers the 250 and 500, separate kits for the 1000 and 2000. A neglected unit loses output incrementally — treatment cycles run longer and jobs take more time without any visible warning. Factor one service kit every 6 months per unit into the total cost of ownership. At current kit pricing this runs well under $100 per unit per year. Units that stay on the maintenance schedule routinely reach the 10–15 year service life Rainbowair rates them for.

Brio Air Filtration = Game Changer
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.

Bedroom machine
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!!
