HVAC systems play a significant role in the air quality of a building, the health of it’s occupants and productivity. Sick Building Syndrome (SBS) is attributed to poor ventilation and control of the building environment.

It is estimated around $50 billion USD per year in productivity is lost due to SBS. This is an average of around $400 per worker, per week.

Effective filtration and air quality management systems are therefore vital for the maintenance of a healthy building. Never has this been more important than in the COVID-19 pandemic world we now live. As air flows around a building, it is sucked in and recirculated through the HVAC system. This means that the ductwork and filters are susceptible to particulate matter build up. These include germs, pathogens, virus’s, mold spores dust and allergens.

So what is Needlepoint Bipolar Ionization?

It is a process that cleans the air inside buildings more efficiently than mechanical filters. It specifically targets airborne pollutants. Ionization happens when particles become positively or negatively charged. These charged particles attract dust and pollutants carrying them to the mechanical filters. Also, bacteria, molds and viruses are killed by ionization. This therefore makes needlepoint bipolar ionization an effective method for controlling diseases in buildings.

Benefits of Needlepoint Bipolar Ionization.

Studies have also suggested that there are other benefits, and that it can contribute to HVAC operational efficiency. This ultimately results in cost savings in the operation of the system.

In addition to the improved system efficiency, there are other benefits to the building occupants. The system limits the flow of outside air, which reduces the containment’s and microorganisms that are introduced to the ventilation system. It also reduces the growth of mold in teh system. HVAC systems are often plagued by mold growth due to the moisture in the system. The growth of mold in duct work can lead to respiratory illnesses, damage to the facilities and foul odors.

Compared to other technologies such as UV air sterilization or steam cleaning of the air, needlepoint bipolar ionization has been found to be more effective and lower cost.

Viral Control.

A problem with viruses is that they may be airborne and also live on surfaces. Bipolar ionization is capable of killing viruses that are airborne as well as those that live on surfaces which an infected person has touched. Surface transmission happens when a non-infected person touches a contaminated surface and subsequently becomes infected thus furthering the spread of illness. In this case needlepoint bipolar ionization is a multi-purpose solution for targeting germs within a building.


Bipolar Ionization is a cost-effective method for controlling the spread of airborne pathogens and pollutants. needlepoint bipolar ions can be introduced to a HVAC system at a low cost. Studies show that the ionization process is effective at killing common germs and viruses including COVID-19. Furthermore, some commercial facilities house allergens that irritate occupants which can lead to respiratory tract illness.

Quality air control is essential during peak flu seasons and has become more prominent in the COVID-19 Pandemic era. Facilities can do more to protect occupants with simple but effective tools such as bipolar ionization to reduce viral load being circulated through the HVAC system.
