What Is Plasma Air Purifier?
Plasma air purifiers use ionization technology to remove airborne contaminants from the air. They are often installed in a building's central air conditioning system, where they produce millions of positively and negatively charged ions as air passes over them. These ions, which have a similar makeup to water, then disperse throughout the occupied space through the duct system.

A plasma air purifier is designed based on advanced technology to improve indoor air quality by removing harmful pollutants and contaminants from the air. It utilizes a process called plasma purification or plasma ionization to achieve this.
Plasma air purifiers create an electrical field that generates positive and negative ions. The ions attach to airborne particles and volatile organic compounds (VOCs). The attached ions then become charged and are attracted to collection plates within the cleaner.
Working of the plasma air purifier
A plasma air purifier, also known as an ionizer or an ion-generating air purifier, operates by utilizing electrical charges to remove contaminants and improve air quality. Here's a general explanation of how a plasma air purifier works:
Ionization
The air purifier generates a high-voltage electrical field or uses an ionization needle to create negatively charged ions (anions) or positive and negative ions (bipolar ions) in the air.
This electric field ionizes gas molecules, typically oxygen or ambient air, turning them into ions.
A corona discharge is created when the electric field reaches a critical level, causing the air molecules near the electrodes to become highly energized.
As the corona discharge occurs, the positively charged ions generated in the process are attracted to negatively charged particles present in the air, such as dust, allergens, bacteria, and viruses.
Ion attraction
These charged ions are released into the surrounding air. They seek out and attach themselves to airborne particles, such as dust, pollen, pet dander, mold spores, and other allergens, pollutants, and microorganisms.
Particle agglomeration
As the ions attach to the particles, they charge them and cause them to cluster together. This process is called aggregation or coagulation. The charged particles grow larger, making them easier to capture and remove from the air.
Electrostatic precipitation
The air purifier typically contains metal plates or collection electrodes with an opposite charge to the ions. These plates are located near the ionization source. The charged particles are attracted to these plates and stick to them due to electrostatic attraction. This process is known as electrostatic precipitation.
Removal of particles
The accumulated particles on the collection plates can be periodically cleaned or washed off to maintain the air purifier's efficiency. Some models have self-cleaning mechanisms that automatically remove the particles from the plates.
Air circulation
The charged ions attached to the dust particles clean up the air and circulate the clean air back to the room.
It's important to note that plasma air purifiers primarily target solid particles and particulate matter in the air. They are ineffective at removing gases, odors, or volatile organic compounds (VOCs) from the air.
Combining a plasma air purifier with other filtration technologies like activated carbon or HEPA filters is often recommended for comprehensive air purification.
Additionally, while plasma air purifiers can help improve air quality, they produce a small amount of ozone as a byproduct.

Cleaning Air Naturally with Cold Air Plasma Filtration Systems




The Air We Breathe
You know the feeling of breathing clean, fresh air such as the air near a waterfall, a beach, or in the mountains? This refreshing air is filled with high concentrations of ions, which are an essential and beneficial component of purified air and healthy living.
Clean outdoor air typically contains anywhere from 2,000-3,000 ions per cubic centimeter. Inside homes with air ducts and an HVAC system, and no specialized filtration, the number of ions is typically below 100 ions per cubic centimeter. Most people spend, on average, 85-90% of their time indoors, thus making improving indoor air quality an urgent matter.
The air we breathe in our homes can easily be 2-5 times more polluted than the outdoor air. Numerous airborne contaminants could be present, including dander, mold, dust, dead skin cells, viruses, and bacteria. Most home air filters capture the larger debris. Microscopic virus particles and living mold and bacterial organisms are often exceedingly small and can pass through a regular series of filters. These contaminants continue to circulate throughout the home's conditioned air. You need a filtration system like a Cold Plasma Generator that can easily be installed in your home's ductwork to filter out the contaminants.
Cold Plasma Generators Defined
A Cold Plasma Generator (or CPG) is a small apparatus that is installed within ductwork as part of a home's heating, ventilation, and air conditioning (HVAC) system. Simply put, the plasma generator creates ions out of molecules in your home's air that can drastically improve the indoor air quality. It is an effective method to protect your home's air quality against bacteria, mold, viruses and more.
How Does a Cold Air Plasma Generator Work?
Simply put, air pulled into your home's ducts from the registers will flow through a plasma field, and molecules in this air will be charged to create positive and negative ions. These ions scrub your home's air clean. When molecules like water (which contains two hydrogen molecules and one oxygen molecule) are broken down in the plasma field, the positively charged ions move into the living space and pull hydrogen electrons from mold, viruses, and bacteria found in the air, thus causing them to die.
Scientifically, this is because of the transformative power of the fourth state of matter: plasma (liquid, solid, gas, plasma). Plasma consists of a gas which becomes highly electrically conductive with ions (atoms with some of their orbital electrons removed) which are mixed with free electrons. Plasma can be generated by heat. This activity occurs when a neutral gas (like oxygen) is mixed with a strong electromagnetic field to the point where an ionized gaseous substance becomes more conducive and sensitive, and in our living spaces it overtakes matter such as dust, viruses, and molds to destroy these contaminants.
Why Invest in Better Air Filtration?
We know "dirty” air can cause illnesses, allergy and asthma flare ups, and even a fine film of dust and epithelial cells (dead skin) on our belongings. The cold plasma generator system is proven to destroy airborne viruses and bacteria which can cause illnesses such as the common cold, the flu, and more serious airborne diseases like Parvo, MRSA, E. Coli, Pneumonia, Meningitis, fungi and other odor causing contaminants such as Volatile Organic Compounds (VOCs). Some of these VOCs are formaldehyde, toluene, and chloroform which are found in pesticides, paints, glues, carpet, solvents, perfumes, and household cleaners. A CPG actually cleans the air in your home while not destroying oxygen and creating little to no ozone (less than four parts per billion).
If a family member struggles with allergies, or asthma, a CPG can remove dust and dander that trigger symptoms like coughing, sneezing, watery eyes, and sore throat. Better air quality makes a tremendous improvement on quality of life and allows family members to breathe freely again. Homeowners can help protect loved one's health and overall quality of life. Using a cold plasma filtration and air cleaning system you will notice that the air in your home is fresher and cleaner. Odors have vanished. Plus, the stress of constant allergy symptoms or other health problems has ceased to exist.
Additionally, a CPG differs from other air purifiers as there is no machine to install, plug in, or hide in your home. Instead, a CPG is installed in air ducts, is always working, and is out of sight. When compared with other air scrubbing systems, CPGs have the lowest cost of ownership because they require no replacement parts. cold plasma generator system requires no additional maintenance, uses only a small amount of energy, and is easily checked (to assure the electrical leads on your system remain clean) and serviced during your scheduled air conditioning maintenance service.
Plasma Air Purifier Vs. Hepa Filter
Using an air purifier becomes essential when the air quality index at your location is not good. You may come across Plasma Air Purifier and HEPA filters as the best options when looking for purifier options. So, this comparison will help you select the best fit for your needs.
What is a plasma air purifier?
A plasma air purifier is a highly effective air-cleaning technology that is not very common currently. These provide air cleaning results that are significantly higher than any other options currently available.
Even if you use some add-ons on purification systems, the plasma cleaner will give better results. On top of that, this technology is cost-efficient and energy efficient, making it a perfect choice for every place.
Working principle
Usually, air purification systems miss a percentage of small particles, including allergens and particles. Plasma cleaners' specialty is that this captures that small percentage left by the other purification systems.
These cleaners use a negative and positive electrical charge in combination, and this flow of charge helps them attract smaller particles after charging them. When the particles are charged and they pass through the cleaner, it results in capturing them.
Effectiveness
The effectiveness of plasma purifiers as stand-alone cleaners is not as good as HEPA filters. It is because these mainly focus on the smaller particles left, and these are budget friendly and not top-rated to capture dust or other bigger particles. However, you can significantly improve the effectiveness of the air purification system at your home by using these as an add-on with another air purification system.
HEPA Filter
HEPA filters are the mostly known filters today as these are known for their amazing filtering results. HEPA filters have unreliable power to remove particles and harmful pollutants in the air. The HEPA filter technology is so widely applicable that it is used in most available air purifiers, brands, and multiple models currently available.
However, unlike the Plasma purifiers, these focus more on the airborne particles, which makes these two slightly different.
Working Principle
HEPA filters differ from traditional filters as they make airborne particles pass through thick pleats. This step seems the same as traditional filters, but the difference here is that it removes as many harmful airborne particles as possible.
As HEPA filters can capture micro particles like allergens, they easily capture larger particles, including dust and pet dander, to maintain good air quality in your home. That's why these make a crucial component in many air purifiers.
Effectiveness
HEPA filters are very effective. These are one of the most effective filters against airborne particles. The filter kills any unwanted organic compounds, tremendously improving the air quality in your home. Additionally, using these filters regularly brings many health benefits, further vouching for their effectiveness.
