BiPolar Ionization | A secret weapon in the war against COVID-19

Compiled by Mr. Khalid Saeed Butt, Proprietor KSB International, Lahore

Bipolar Ionization (BPI) solution improves health and wellness by actively restoring indoor air to its pure natural state where no pollution or contaminants exist, while reducing energy use and emissions in the process.

One of the fastest evolving technologies, introduced in HVAC Industry in the past 15 years is Bi Polar Ionization (BPI). Researches indicate that ionizing the air can stop spread of viruses, kill pathogens and neutralize them. To achieve better performance from HVAC Systems and to deactivate Covid 19 virus, remove harmful substances like airborne mold spores, VOCs, bacteria, dust particles, fungi, allergens and odors in the air where you breathe, BPI is an effective solution to provide purified and healthy air. 

By understanding the capabilities of Bi Polar Ionization to kill pathogens, and properly applying the technology to air handling units, we will be employing a technology to our air handling units which will disinfect the supply air stream as well disinfect the AHU.

It’s an alternate to the Ventilation Rate Procedure (VRP). BOP system has energy saving benefits too.  OA rate can be reduced to more than 50% of those required under VRP. It means that AHU size can be reduced, extend life of filters and save energy consumption cost.

How BiPolar Ionization Technology works? 

BiPolar Ionization Technology releases charged atoms that attach to and deactivate harmful substances. 

Bi Polar Ionization (BPI) is a gas phase indoor air purification technology. It works by adding a controlled amount of both positive and negative air ions to the supply air of air handling system. The negative ions contain an extra electron while the positive ions are missing an electron resulting in an unstable condition.

Integrated into HVAC systems, the BiPolar Ionization technology utilizes specialized tubes that take oxygen molecules from the air and convert them into charged atoms that then cluster around micro-particles surrounding and deactivate  harmful substances like airborne mold, bacteria, allergens, and viruses.

“The ions produce a chemical reaction on the cell membrane surface that inactivates the virus,” It can reduce 99.9% of microbes in 30 minutes.

Benefits of BPI

  • Microbial and pathogen reduction: Airborne molds, bacteria and viruses (including human corona virus) are killed or deactivated by oxygen ions. This process begins in the air as soon those contaminants are emitted. (by coughing or sneezing)
  • Particle Decay: Particles including pm 2.5, stick to one another due to the ion charge (a process called agglomeration) and fall out of the breathing range and / or are more easily captured by the filters in HVAC system.
  • VOCs and Odors reduction: Chemical off-gases and offensive odors are eliminated by the interaction with ionized air, eliminating the use of masking agents that add to indoor pollution.
  • Energy Conservation: With an engineering air purification approach, ASHRAE’s 62.1 guidelines allow you to reduce the volume of outside air while providing the above benefits and greatly improving the indoor air quality.

System Placement

Can be mounted in different sections of the air distribution

Why BPI is different than UV light


BPI solution removes inhalable particles and pathogens including dust, allergens, molds, VOCs, odors, airborne and surface bacteria, viruses and germs to create healthy indoor environments where people thrive while doing efficiently and cost effectively.
