Different Kinds of Ionizers

For a better understanding, I am going to explain three different ionizer types. Let’s check them out:

1. Bipolar Ionization

It is a technology that generates both positive and negative ions in the air. However, it frequently works with other gadgets, such as HVAC systems. PURE Plasma Air 600 is an example of this technology.

Some of its health benefits are:

  • It reduces the concentration of airborne particles, thus enhancing your indoor air quality.
  • It also can disintegrate and neutralize the molecules that cause bad smells, resulting in a more fragrant atmosphere.

However, apart from its benefits, it can also produce irritants that make your asthma and allergies worse. Plus, these ionizers also have the potential to generate ozone.

2. Fan Ionizers

An ionizer fan is a device in which an ionizer is attached to a revolving fan that helps you purify the air as it cools down. Let’s see what benefits this device offers!

  • It improves the ventilation of your room.
  • It can also remove dust and allergens from the air, providing an allergen-free environment.

In addition to its benefits, it can produce ozone, which is potentially dangerous for people’s health, particularly for children and elders. These ionizers include a Molekule Air Purifier.

3. Air Purifier with Ionizer

Ionizer air purifiers combine conventional air purification techniques. They usually use filters for larger particles, and for smaller particles, they use ionizers. Now, let’s shed some light on the benefits of this wonderful air cleaner.

  • It can lessen your stress and enhance your sense of well-being.
  • Due to its all-encompassing approach to air purification, it is ideal for those who suffer from allergies or asthma.

However, I recommend purchasing an air purifier with an ionizer like InvisiClean Aura II, which is generally considered the safest among all the above ionizers. This is because they are made to be certified by EPA, which guarantees that air purifiers produce no ozone

Can Ionizers Eradicate Viruses?

The quick answer is that Ionizers don’t eradicate viruses. However, by producing charged particles, they trap viruses from the air.

Can Ionizers Eradicate Viruses?

Here are some steps of how these air cleaning devices work.

  • Ionization: Ionizers emit negative air ions that adhere to airborne particulates, making them heavier.
  • Particle Agglomeration: These ions can cause viruses and other particles to the group, facilitating their absorption onto surfaces or removal by air purifiers.
  • Decreased Airborne Viruses: Due to their heavier nature, these particles are less likely to hang in the atmosphere, which may reduce the chance of breathing them in.

In addition, according to Scientific Review 2020, ozone generated by ionizers can render viruses inert in the atmosphere and on surfaces.

Moreover, during my research, I found numerous studies demonstrating how effective ionizers are at preventing infections. According to research on guinea pigs, an ionizer was 100% effective in preventing influenza infections.

Perks of Using An Air Ionizer

Last week, I bought a B1000 – Purifier with Ionizer for my home; to my surprise, it’s been a game-changer. My room smells better, my allergies are less severe, and my space feels more airy.

Perks of Using An Air Ionizer

Anyway, enough prattle on. Here are some noticeable benefits of using an air ionizer in your home. Let’s check them out!

  • Inhibit Microorganisms: The air ionizer acts as a silent protector by inhibiting the growth of certain types of microorganisms like mold, bacteria, and viruses.
  • Allergen Reduction: Sick of being sniffly? Air ionizers combat allergens such as smoke and pet dander, creating a comfortable and allergy-free environment in your home.
  • Mood Booster: When it comes to improving your mood, negative ions from ionizers may be your best friend because they increase serotonin levels in your body. As per another study published in PubMed, the negative ions decrease stress and support mood. They can also help you focus and feel better about yourself.

Demerits of Using Ionizers

Although ionizers can eliminate certain items from your home, they have disadvantages. So, before investing in an ionizer, it’s essential to consider these risks.

Demerits of Using Ionizers

These disadvantages are as follows:

  • Limited Effectiveness: Compared to other air purification techniques like HEPA or carbon filters, ionizers might be less efficient at capturing and eliminating larger particles like pollen, dust, etc. Ionizers like air purifiers can only capture particles up to 0.1 microns. The smaller dust particles can deceive them.
  • Ozone Emissions: Certain ionizers produce ozone as a byproduct, acting as ozone generators. This occurs when negative ions electrically charge airborne particles. Its prolonged exposure can lead to various health problems like coughing, chest pain, difficulty breathing, and a high risk of respiratory infections.
  • Produce Ultrafine Particles and VOCs in The Air: Air ionizers produce VOCs and ultrafine particles as a by-product in your environment. When inhaled, they directly penetrate your lungs, causing health problems like decreased lung function or worsening asthma.

But, here, I also want to address a statement by David that I found during my study:

Ionizers vs HEPA Filters: A Quick Comparison

HEPA filters and ionizers are different air purifiers that improve indoor air quality but have different operating principles. To upgrade my air purifier, I thoroughly compared these models. Let’s go through them quickly!

1. HEPA Filters

HEPA filters, or High-Efficiency Particulate Air filters, capture dust, allergens, volatile organic compounds, spores, bacteria, and tobacco smoke in the air using a dense physical filter. The best HEPA filter can capture 99.97% of particles with a size of 0.3 microns or less.

2. Air Ionizers

Conversely, ionizers discharge negatively charged ions into the atmosphere, which form bonds with hazardous contaminants. As a result, the particles become heavier and settle, making it easier for surfaces or air purifier filters to collect them. Therefore, ionizer air purifiers keep your environment clean, preventing dust particulate matter and improving immunity.

However, certain ionizers usually release ozone, a powerful lung irritant, in an environment, so I don’t suggest using it for people with bad respiratory conditions. Moreover, if you are looking for a safer option, I recommend using HEPA filters in your home as they are considered safer and more effective than ionizers.
