Why Should You Care About Indoor Air Quality?

Even before the current coronavirus pandemic, indoor air quality has been a serious topic.

As buildings have become more and more sealed off outside air, gases, microorganisms and other airborne particulates have filled the air with little way to leave.


Ventilation systems are limited and rely on filtration to remove these harmful items when a fresh air intake is not present.

 What is the difference between an air purifier & the PuriGuard Fresh System by JD Air?

Air purification in its simplest definition implies removing “things” from the air that pollute it. A general concept is that some method of filtration will be used to remove those “things”. The fulfillment becomes very complicated because of the nature of air. Clean air is an invisible mixture of gases that move around or flow with some level of force. Polluted air is a mixture of invisible clean air along with harmful gases and particles.  The additional airborne particles and gases move or float based on their molecular makeup. That means that some things in the air do not move or behave the same as clean air as it is flowing.

Now, think of an air purifier in a room or home. When operating, it moves air through the device by creating or taking advantage of existing airflow. Any air that flows through the device is cleaned (by inactivating microbes, think UV light) or filtered (by trapping undesirable particles in the device, thus removing them from the air; think HEPA). Some devices do both. However, any air that does not flow through the device is not cleaned or filtered. Also, filters must be able to allow clean air to pass through while trapping particles and gases. The challenge is that some particles are extremely small (500M or more on the head of a pin). These products do work on any air that passes through these devices, but because of the nature of air, we know that all pollutants will not go through the device.

The PuriGuard Fresh system is different in that it integrates with your existing HVAC system(s) to proactively 1) seek out 2) inactivate and 3) remove microbes, VOCs and other air pollutants in the entire home or building’s conditioned space. There are other factors too that distinguish it from air purifiers. Well beyond the capabilities of an air purifier, PuriGuard Fresh optimizes the airflow throughout the conditioned space for thorough purification. Fresh air is then introduced in a controlled manner while limiting energy spikes. 

How does the PuriGuard Fresh system proactively seek out & inactivate airborne pollutants?

The PuriGuard Fresh system proactively sends out positively and negatively charged plasma which is drawn to airborne and surface particulates like a magnet.  The plasma that the devices send out is composed of compounds proven to inactivate (kill) microbes but are safe for people (think hydrogen peroxide). The binding nature of the plasma causes inactivated but still airborne microbes and particles to clump together, weighing them down and allows them to be trapped by your system’s existing air filter (now that they are too large to bypass the filter) or fall out of the air as general dust.  The in-duct LED/UV light adds an additional layer of protection against microbes (like mold and mildew) that may otherwise be present on the system’s evaporator coils and other moist, covered components.


Volatile Organic Compounds (VOCs) produced by the evaporation of additives in many consumer products (think- the chemicals on carpet to make it stain resistant) and odors are also drastically inactivated and reduced by these air purification systems. That’s good news because of the harmful effects of VOCscombined with the amount of time most people spend indoors.

What can you expect after installing PuriGuard Fresh by JD Air?

Does that mean it is not possible to get sick with coronavirus or any other illness? Are all of your allergies guaranteed to disappear with the installation of this product?


The whole home or building air purification systems that JD Air recommends are proven to reduce odors, VOCs, smoke, mold, bacteria and viruses in the air AND on surfaces. However, our air purification systems will not eliminate the need to wash your hands properly and maintain a healthy lifestyle. PuriGuard Fresh does not treat health conditions in humans or animals.Also, regarding your HVAC system(s), changing your filters will become even more vital since more particulates will be removed from the air and trapped by them. Any particles previously in the air that fall as dust (including pet dander & pollen, that some are allergic to) remain present until wiped, swept or mopped away. 


Even though the coronavirus pandemic seems to have already peaked, minimizing home or building microbes, allergens and VOCs is still very important. The wholistic nature of the PuriGuard Fresh system makes these systems the best solution for air purification.
