Airmaster Ultra


With the COVID-19 pandemic happening, I know we are all very concerned about VIRUSES in the air!  So, what can you really do to clean the air inside your home?  Most people will say replace your furniture filter regularly, but that isn’t enough!  Did you know that EPA studies indicate that air quality in the average home can be 4 to 40 times dirtier than the outside air. When you think about all the time your family spends indoors, doesn’t it make sense to give them the best quality air you can?

  • Reduces airborne contaminants
  • Helps eliminate household odors
  • Leaves your air fresh and clean
  • Treats the entire house, not just one room.


  • Uses less power than a standard light bulb—draws only 47 watts of power.
  • Automatic airflow sensor means the ozone lamp is operating only when air is flowing.
  • Plugs into any standard outlet.
  • Operational status is easily determined at a glance with the LED indicators.
  • Lid interlock safety switch.
  • Remote status indicator available.
  • External odor control adjustment makes it easy to adjust for changing home air quality.
  • “J” lamp kit available for smaller ducts.

Installation. The Airmaster Ultra is installed in the air duct in your home’s heating/cooling system. The system works using two safe and time-tested technologies, ultraviolet light and ozone.

UV Purification. Air passes by the light of the
UV lamp, where many common bacteria and molds are reduced.*

Ozone Purification. The air then passes by a specially designed lamp that produces a very small, controlled amount of ozone. Ozone is a strong oxidizer that reduces problem odors from cooking, pets and other sources, leaving behind fresher, cleaner air.

Continuous Air Quality. Whenever your heating/cooling system is on, the Airmaster Ultra works silently and continuously, leaving fresher, cleaner air throughout your home.

Low Maintenance. The only maintenance the Airmaster Ultra requires is periodically changing the UV and ozone lamps, a service that your RainSoft dealer will perform for you.

*Test performed by independent lab. Test results are available upon request.

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 (Fig. 1). 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 within the UV light zone (Fig. 2a), most airborne viruses, bacteria and molds are killed or sterilized. From there, the air passes by the ozone lamp (Fig. 2b) where odors are neutralized. The process happens continuously and silently as your heating/cooling system runs, and there are no messy filters to change.

Here is an update on what we are doing during this crisis:


When You Schedule an Appointment with Us & Before We Arrive:

We are monitoring all team members for any relevant symptoms and are acting accordingly.  Any team members that have a fever, show signs of illness, or have been known to be exposed and not protected will be asked to stay at home. 


When We Arrive:

Our technicians are supplied with hand sanitizer, disinfectant wipes, masks, gloves, and as always, shoe covers. These items are in high demand right now and can be difficult to obtain in bulk, but we are doing our best to keep these items in stock.  Other Measures we are implementing for our technicians are limiting time in groups, as we have cancelled all staff meetings until further notice. Technicians already work in isolation for most of the day and are rarely exposed to large groups. We will be limiting face to face interaction between our office team members and field technicians.  We greatly appreciate your patience with our team during this time, as it allows us to provide the best service possible to those in need of our services. We need your support in order to provide the services needed while keeping safety at the forefront. 


While in Your Home:

We are still scheduling and running service and maintenance calls during this time. We have asked our technicians not to shake hands and to keep a safe distance from our customers. We don’t mean to be unfriendly, but we feel it is in everyone’s best interest to take reasonable precautions during this health emergency. In a lot of cases we can troubleshoot equipment from your basements or kitchens with minimal face to face contact.  If you are already on the schedule for maintenance, we plan to provide service, however you are welcome to reschedule.  As mentioned above, we can often work on equipment with minimal contact. Filters inside the home will need to be changed and we intend to do so with your permission. System maintenance is still very important and does not need to be put off for too long or ignored all together. Obtaining signatures for work is our normal process is for repair work to be approved, if you do not feel comfortable with this, we can forego getting your signature at this time.  Also, if you want to avoid hand to hand transactions while paying, you can read off your debit or credit card information to the technician at this time.   If you do not wish to provide this information to a technician, you may call our office to submit your payment.  


Indoor Air Quality Basics:

COVID-19 is spread through airborne particles as well as other means.  As experts in indoor air quality, we recommend a few things:


  • Change your air filter regularly 
  • Invest in a Whole-House Ultra-Violet Light system to kill viruses and bacteria in your home. Ask our technician about our Airmaster Ultra Air Purification System.  This system kills viruses, molds and bacteria in the air.
  • Change your Airmaster UV bulb if it is over 2 years old.
  • Make sure the humidity in your home is between 35% – 50%.


Updates from RainSoft of NE Iowa Water Treatment & Plumbing:

At this time we will send out communication via email and social media. We greatly appreciate our customers and team members here at RainSoft of NE Iowa Water Treatment & Plumbing.  We understand the value of doing our part to reduce the spread of this virus so that our healthcare system is not overwhelmed and those in need can receive the best care possible. We are confident that we will be able to handle this predicament as quickly as possible and return to normalcy soon.  I know having a technician in your home during this trying time can be a concern. But please rest assured that we are taking measure we can in order to keep you and our team safe. 


Thank you for putting your trust in us, and please stay safe.
