Reduce Outdoor Air with Needlepoint Bipolar Ionization

How to Reduce Outside Air via ASHRAE Standard 62  

This brief video explains how Global Plasma Solutions (GPS) utilizes ASHRAE Standard 62 Indoor Air Quality Procedure to reduce outside air by up to 75% over the conventional Ventilation Rate Procedure (dilution method).   Using GPS’ IAQ software an engineer can see how low the outside air can go subject to building pressure in non-healthcare applications. According to a great air conditioning contractor a rule of thumb, the outside air can be reduced to 5 CFM per person by allowing GPS’ patent pending air purification systems to clean the air in the building and recirculate the already conditioned inside air versus treating higher quantities of outside air.

Testing Shows Pathogens 99.4% Inactivated by Needlepoint Bipolar Ionization

Testing is in –  Needlepoint Bipolar Ionization Inactivates Pathogens! 

This is great news for our HVAC community.  This technology can be easily added to most HVAC systems quickly and at a very reasonable cost.

We had tested other virus types with great success and had suspected the same result against the most current pathogen.  We are now able to share that third party testing shows that Needlepoint Bipolar Ionization inactivates 99.4% of current pathogens in 30 minutes.  These are very, very good results!

Complete Report:  Needlepoint Bipolar Ionization – Test Results

Is it safe?

Bipolar ionization has been around for decades. This technology will not generate anything that is not already prevalent in the atmosphere.  Ions are healthy and they are abundant in normal, outdoor environments.  The older style of ion generators used perishable glass/composite tubes and would also create potentially harmful ozone during the process.  A newer technology uses Needlepoint modules to develop bipolar ionization.  They were developed in the mid-2000’s and do not create harmful levels of ozone.  Needlepoint technology has been tested in accordance with UL 2998, which limits ozone to 0.005 parts per million (5PPB) by volume.  These systems are safe for indoor environments.

Is it cost effective to Install?

Needlepoint bipolar ionization (NBPI) can be installed in existing or new HVAC equipment. This type of technology is a simple addition to most any HVAC system. You can also have it done when you’re in need of air filtration repair. It does not involve increasing system pressure, adding fans, up sizing filters, or making large changes to air handlers or duct work.  In most cases, NBPI can be simply attached on the entering side of a cooling coil. NBPI products require little maintenance and most require no replacement parts. NBPI products are typically designed to last the life of the associated air handling system.

The University of Wisconsin will welcome a limited number of athletes back to campus this week, with voluntary strength and conditioning activities to begin June 15.

The plan includes the voluntary return for members of the football and volleyball teams for health assessments and COVID-19 testing. Next week’s strength and conditioning activities will all take place in the Forward Center inside Camp Randall Stadium and in the weight room at the McClain Center. Other facilities, including the Kohl Center, will remain closed.

The number of athletes inside each room will be restricted to mitigate risk of spreading COVID-19. Athletes will be screened daily (including a temperature check) before entering the facilities.

Athletes will be briefed on full health procedures, and each athlete must undergo nasal-swab testing for the virus. If they develop symptoms or believe they have come into contact with someone who has tested positive, they will be swabbed again.

The athletes will be required to wear masks except during conditioning activities. Those with suspected symptoms will be instructed to self-isolate while awaiting test results, and they’ll be required to sit out for 72 hours after receiving a negative result.

An individual testing positive must be symptom-free for 72 hours before receiving a repeat COVID-19 test. Upon receipt of a negative result and follow-up exam, the athlete can return to gradual participation once cleared by a team physician.

Needlepoint Bipolar Ionization (NBPI) added by Global Plasma Solutions

UW said it was installing Global Plasma Solutions bi-polar ionization units to air-handling units in its facilities, employing a process that helps kill viruses in the environment. The university is also ramping up cleaning procedures.

Members of the basketball team will return later in June, followed by hockey teams. Additional athletes will return for voluntary workouts as the summer progresses, provided all goes well.

“We have been working for several weeks on a carefully-constructed plan to begin welcoming our student-athletes and selected staff members back to campus,” UW athletic director Barry Alvarez said in a UW release. “We’re very happy to be able to take this step forward, but very cognizant of the need to take great care that our people remain safe. I want to thank our staff, the medical professionals we have worked with and our campus leadership for their efforts in helping us.”

Needlepoint Bipolar Ionization (NBPI) Increases Filter Efficiency to Fight Current Pathogens

How to save on expensive cost of up-sizing filters  

Needlepoint Bipolar Ionization technology produces positive and negative ions that travel with the supply air into the space. In the space, these ions cause particles like dust, dander, pollen, bacteria and virus to attract and stick together (agglomeration). This action significantly increases the effectiveness of existing filters. MERV 8 + GPS = MERV 13.

COVID-19: Creating a Safer Workplace with an HVAC Solution

How Does COVID-19 Spread?

It is extremely important to understand how the COVID-19 virus is spread.  What we know is that this is an extremely small virus.  It is about 0.12 microns which is tiny (a human hair is 50-70 microns).  Being this small, the virus doesn’t travel well by itself. There are three ways that people get infected.

Droplets  When an infected person coughs, sneezes, or talks, droplets with the virus fly into the air from their nose or mouth.   Anyone who is within 6 feet of that person can breathe those droplets into their lungs. These droplets do not stay in the air. They fall to surfaces.

Aerosolized transmission  Research shows that the virus can live in the air for up to 3 hours.  At 0.12 microns, the virus just floats around in the air.  The smaller the size, the longer it stays airborne.  When you breathe air that has the virus floating in it, the virus can travel deep into your lungs.

Surface transmission   You can also catch COVID-19 by touching surfaces such as counter tops or doorknobs which have been coughed or sneezed on by someone who has the virus and then touching your nose, mouth, or eyes. The virus can live on surfaces like plastic and stainless steel for 2 to 3 days. To stop surface transmission, surfaces must be cleaned thoroughly.

How can HVAC systems reduce the spread of COVID-19?

An HVAC Solution: Needlepoint BiPolar Ionization (NBPI)

A reasonable solution to this problem would be to add something to the supply air delivered to the space which would inactivate aerosolized and surface virus.  This additive needs to be safe for humans and added at a reasonable system cost. That would be a great solution.

Bipolar Ionization of Air

As crazy as it sounds, this solution is already available.  Ionization of air has been around since 1879.  Actually, it’s been around since the beginning of time.  Ionization of air occurs naturally in our world and is strongest around crashing ocean waves, waterfalls, mountains and electrical storms (the freshest air available).  There are manufacturers that provide products that that can cost effectively add ions (both negative and positive) to supply air.  These products have been tested, proven and made available in the HVAC market for over 20 years. They have not gained wide acceptance because building owners have not been motivated to use them. They provide fresh, clean air which has not been a priority for most buildings.   Until now, buildings were designed for comfort, cooling and heating and not necessarily for indoor air quality or to protect the occupants in the building.  This has now changed. Today, that is what we need.

How does Bipolar Ionization work?

Bipolar Ionization starts at the air handling unit where millions of ions per second (positive and negative) are produced and then travel through the duct work and into all building spaces.  In the space, these ions provide two key functions; particle reduction and pathogen reduction.

Particle Reduction

Let’s say a person sneezes in a space.  At that point, millions upon millions of virus particles are launched into the air where they will remain for a long time.  Because COVID-19 is so small, the virus particles will not be swept along in normal air currents.  They will stay suspended in the space environment for up to 3 hours.  The positive and negative ions that are generated with Bipolar Ionization technology travel with the supply air into the space.  In the space, the positive and negative charged ions release their charge to particles (like dust, dander, pollen, bacteria and virus).  Those particles in turn seek out oppositely charged particles and stick together (agglomeration).   Through particle agglomeration, they start sticking together and growing larger.  As they gain more and more surface area, the particles become large enough to be moved by the airflow back to the filter.  They are captured and retained in the filter at the air handling unit.  Since both polarities of ions are created, particles are not attracted to objects in the space and the overall net static charge is neutral.

Pathogen Reduction

Bipolar ionization injected into the air attacks and inactivates viruses and kills mold spores and bacteria. With living organisms like mold spores and bacteria, the ions steal away hydrogen from the pathogens, leaving them to die.  If it is a virus like COVID-19, it is not a living organism and it is not going to have hydrogen in it.  In this case, the ions produce a chemical reaction on the cell membrane surface that inactivates the virus destroying its ability to reproduce.  Bipolar ionization can reduce 99.9% of microbes in a matter of minutes.  This pathogen fight takes place in both air and on surfaces, within the space (not just in the air handling unit).  Another huge advantage is that bipolar ionization purifies the space on a continuous basis, not just during application (like chemical disinfectants or even portable UVC systems).

Is it safe?

Bipolar ionization has been around for decades. This technology will not generate anything that is not already prevalent in the atmosphere.  Ions are healthy and they are abundant in normal, outdoor environments.  The older style of ion generators used perishable glass/composite tubes and would also create potentially harmful ozone during the process.  A newer technology uses Needlepoint modules to develop bipolar ionization.  They were developed in the mid-2000’s and do not create harmful levels of ozone.  Needlepoint technology has been tested in accordance with UL 2998, which limits ozone to 0.005 parts per million (5PPB) by volume.  These systems are safe for indoor environments.

Reducing Spread of COVID-19 with HVAC System Retrofit

Using GPS Needlepoint Bipolar Ionization to Retrofit and Upgrade Existing HVAC System

The challenge for reducing the spread of COVID-19 has two categories. One of them is our daily behavior which includes social distancing, wearing masks, cleaning, and sanitation as recommended by CDC. The other category is office lay out, occupant flow and HVAC improvements.

For years, there have been known proven methods for cleaning the supply air. There is a difference between providing cleaner air to the space and eliminating the pathogens from the contaminated environment.

To reduce the pathogens from the air supply through the HVAC system and thus reducing the spread of pathogens, we recommend Bipolar Ionization provided by Global Plasma Solutions.

Bipolar Ionization has been used for clean rooms and health care facilities for many years. It is relatively simple concept and can be applied to traditional ducted systems. Producing a natural bio-climate rich in positive and negative oxygen ions will help neutralizing the particles. The negative ions contain an extra electron while the positive ions are missing an electron resulting in an unstable condition. In an effort to restabilize, these bipolar ions seek out atoms and molecules in the air to trade electrons with, effectively neutralizing particulate matter, bacteria and virus cells, odorous gases and aerosols, and VOCs.
