Your home traps more than just air.
Cooking, pets, humidity, and everyday living leave odors, airborne bacteria, and mold spores circulating through your home. The AirMaster Ultra treats that air where inside your HVAC system.
Runs on about the same energy as a standard lightbulb.
UV-C light plus adjustable activated oxygen to target odors, airborne bacteria, and mold.
Duct-mounted at the source, so treated air moves to every room your heating and cooling system serves.
Why treat the air at the ductwork?
The AirMaster Ultra sits inside your ducts, every time your furnace or AC runs the air passes the unit first — so the whole house is treated .
What it targets
- Cooking & pet odors
- Tobacco & musty smells
- Airborne bacteria
- Mold spores & mildew
- Household VOC odors (paint, renovation, cleaning products)

"Our finished basement always had a musty smell no matter what we tried. Since Pure H2O put the AirMaster in our ductwork, the whole house just smells cleaner. You forget it's even there."
"Between two dogs and a lot of cooking, the house needed help. The consultation was low-key and honest, installation was quick, and the difference in everyday odors is real."
"Pure H2O has handled our water for years, so we added the AirMaster when we redid the HVAC. Same great service — they explained everything and there's nothing for us to fuss with."
Questions Ohio homeowners ask us most.
What does the AirMaster Ultra actually do?
It's a whole-home air treatment system that mounts inside your HVAC ductwork. As your furnace or AC circulates air, UV-C light and adjustable activated oxygen work to reduce odors, airborne bacteria, and mold — so the air moving through your home is treated at the source rather than in a single room.
How does this work with my standalone air purifier?
They make a great team. Your standalone unit gives you focused, always-on cleaning right where it sits — even when the HVAC is off. The AirMaster Ultra adds whole-home coverage through your ductwork, so every room your system serves gets treated too. Together you get continuous, layered protection instead of relying on any one unit.
Does it use ozone — is that safe?
The AirMaster Ultra uses adjustable "activated oxygen" (ozone) alongside UV-C light, and the output is set by your technician for your home's size. It's designed to be dealer-configured within the manufacturer's recommended range. During your free consultation we'll explain exactly how it's set up and answer any questions before anything is installed.
What's the upkeep — do I have to change filters or bulbs?
It's simple, routine upkeep. Every so often the UV/ozone lamp needs replacing — and a filter where applicable — which is a quick change, not a hassle. Our local Ohio team can take care of it for you, ship you the parts, or send easy step-by-step instructions so you can do it in a few minutes. Whatever's easiest for you.
Will it work with my existing HVAC?
In most cases, yes — it's designed to install in standard residential ductwork and interlock with your heating and cooling system. The best way to confirm the fit for your home is a free in-home consultation, where we look at your setup and recommend the right placement.
How much does it cost?
Pricing depends on your HVAC setup and installation. After a free in-home consultation, we'll give you a clear, transparent quote — no high-pressure sales and no surprise upsells. Flexible financing is available.
