Anti-Viral HVAC Products

UV Lights

In 2007 the American Journal of Public Health published a paper describing how masks and UV lights could help blunt the effect of an influenza pandemic. The opening sentence of this paper states “In the event of an influenza pandemic, where effective vaccine and antiviral drugs may be lacking, disrupting environmental transmission of the influenza virus will be the only viable strategy to protect the public.” You could replace the words “influenza virus” with “coronavirus” and that sentence would describe our present situation in the country today.

Ultraviolet wavelength light, especially in the “C” spectrum of UV waves, in sufficient quantities will severely damage the DNA and RNA of a virus. This destroys the ability of the virus to replicate thus neutralizing it. It has even proven effective in inactivating the Ebola virus.

Sanders and Johnson has sold this type of UV product for several years. It mounts inside the return air drop and “zaps” air flowing down the duct and again when it flows away from the unit. Any viruses present in the return air system are treated with UV light for the maximum amount of time possible. We presently have about a dozen of these units in stock. Our normal pricing per unit is anywhere from $1400 to $1600 but we have recently dropped the price depending on make and model.


Researchers at Yale University published a paper in May of 2019 describing how low humidity can prevent small hair-like structures inside airway cells from removing flu virus particles. The same study also revealed low humidity seems to impede the ability of these airway cells to repair damage caused by the virus inside the lungs. SARS, a virus from the same family as CoVID-19, is more persistent in environments with a low relative humidity and low temperatures. If you are interested in purchasing a humidifier, we have dropped the price to $600 for our most basic bypass model.


This equipment produces negative air ions which are blasted out of the ionizer onto particles suspended in the air. These particles then develop a charge. Charged particles will aggregate together and become so heavy they fall out of the air. This technology has existed for years. The negative ions themselves will inactivate viruses although researchers do not yet understand why.

We Want To Help You Stay Safe

So to wrap this up, we are offering discounted pricing for a limited time on three products research has shown can help protect against viruses. To be crystal clear, we do not claim that:

  1. UV lights, humidifiers, and ionizers are guaranteed to prevent infection by the coronavirus or any other virus.
  2. UV lights, humidifiers, and ionizers will cure those already infected.

We do claim that these devices can significantly decrease the likelihood of contracting the infection, which we believe is a very good thing.

Please take care of yourself and your loved ones. Stay safe, stay healthy, and look for examples of kindness, patience, and gratitude.
