How does the AirPal Spectra air purifier work?

The AirPal Spectra™ is installed in your heating/air conditioning duct system. There are two specially engineered lamps that emit UVC light which greatly reduces or eliminates mold, bacteria and viruses circulated by your system.

How does germicidal UVC light kill microorganisms?

UVC light destroys microbes by being absorbed by the proteins within the microorganism. After absorption the UVC light destroys the microbe or inactivates the DNA which prevents the microbe from reproducing. A microbe is considered destroyed when it can no longer reproduce.

Has this technology been tested?

Yes. Both Westinghouse Electric and General Electric conducted laboratory tests on the germicidal effectiveness of air purification through UVC lights on microorganisms. Germicidal UVC light is used for air purification in hospitals, food processing plants and commercial buildings.

Has the AirPal Spectra air purifier been tested?

Absolutely! Environmental Compliance Solutions of Troy, Michigan independently tested the AirPal Spectra air purification system in actual homes. Airborne mold and bacteria dropped an average of 84% and brought levels within healthy standards.

Don’t filters eliminate germs, viruses and molds?

No. Filters trap the microbes and even the most sophisticated ones do not contain 100% of the germs and viruses. These microbes reproduce very quickly and those not trapped will recontaminate your home.

Is UVC light harmful to people?

Prolonged, direct exposure to UVC light is harmful to all living organisms, people included. However, the AirPal Spectra™ air purifier has been designed so there is no exposure to people. This provides for safe operation and maintenance.

What is the life of the UVC lamps?

The lamps are rated at 9000 hours which is approximately one year.

Does the AirPal Spectra™ air purifier operate continuously?

Yes. The AirPal Spectra™ is working 24 hours a day. This is not true with some other units that shut on and off with the system’s blower motor.

Is the AirPal Spectra™ expensive to operate?

No. It uses less energy than a 60 watt light bulb.

How do I know when it is time to replace the bulbs?

The lamps provide germicidal effectiveness for 9000 hours or 1 year. The bulbs may glow longer than one year but they are not adequately killing microbes. Your contractor should contact you at the appropriate time to change the lamps.

How can I get an AirPal Spectra™ installed?

You can install the AirPal Spectra™ yourself by following our installation guide. Or contact your heating/air conditioning contractor. If you cannot find a contractor that carries the AirPal Spectra™, email us at for the name of a contractor in your area for installation.
