Air Purification

Airmaster Ultra


Cleans and freshens the air in your home by sterilizing or killing many contaminants and neutralizing unwanted odors.


Uses two safe and time-tested technologies: the ultraviolet (UV) light kills many airborne bacteria and molds that contribute to household allergies; the specially designed ozone lamp effectively neutralizes problem odors from pets, cooking and other household sources. Operational status is easily determined at a glance with LED indicators.


Uses special nonfilament UV lamps that last three times longer than a standard filament lamp. Unit draws just 47 watts-using less power than a standard light bulb.

Fail-Safe Features

Automatic airflow sensor allows the unit to operate only when air is flowing from your furnace or air conditioning system.


The only maintenance required is periodically changing the lamps, a service performed by your RainSoft dealer.

How an AirMaster Ultra Works

Understanding Air Purification

You may be familiar with air filtration products, but the Airmaster Ultra is actually an air purifier. The diagrams below help explain the difference. Air filters are also called “mechanical filters.” They work by trapping particles that are too large to pass through.

They collect larger particles, but may not be as effective for many smaller particles. The filters must be changed on a regular basis, as they fill up with the collected debris (much like the bag on a vacuum cleaner).

Air purifiers, on the other hand, actually sterilize or kill most contaminants. Both UV and ozone are purification methods. In the Airmaster Ultra, when air passes through the UV light zone , most airborne bacteria and molds are killed. From there the air passes by the ozone lamp, where remaining odors are neutralized. The process happens continuously and silently as your furnace runs, and there are no messy filters to change.

Understanding Air Purification

Did you know that the EPA has found that the air within homes and other buildings can be more polluted than the outdoor air—even in the largest and most industrialized cities? Government research also indicates that people spend approximately 90 percent of their time indoors, for many people, the risks to health from indoor air quality may be greater than the risk from outdoor pollution.
