Here is a comprehensive guide about the best air ionizers and how you can choose the right one according to your preferences and requirements.

What is an Ionizer?

Air ionizers also referred to as ion generators or iconic filters, are the well-known air filters that are used in air purifiers. These filters emit negative ions into the air which connects to positive ions like dust and pollen to eliminate them and improve air quality. The charged clouds of negative ions attract the particles in the air which then fall into the nearby charged collector plate or gather in the mechanical filter. This is a very powerful device which is capable of reducing the size of 99.8% airborne particles to as tiny as .01 microns.

How Do Air Ionizers Work?

Unlike the regular air purifiers that use fans for pulling the polluted air within a filter, these negative air ionizers only release negative ions clouds which cause electric charging of the air molecules. These molecular particles called ions attach themselves to the oxygen present in the air and develop a negative charge.

After becoming a negatively charged ion, these molecules attach to the pet dander, pollen, dust particles, and odor and create a cluster. This cluster is then pulled into the air filter. You can then easily remove the air filter and clean or replace it as per requirement.

Can Air Ionizers Be Harmful?

Air Ionizers work on the mechanism of generating negative ions. Studies have shown that exposure to the negative ion has a positive impact on human life. There is no harm done to the human body from these negative ions. However, Ozone Generators promoted as Air Ionizers are harmful. They operate differently than normal Air Ionizers. These Ozone Generators, much like their name, work by generating ozone into the air of our houses. Ozone is a natural phenomenon that can counteract these pollutants. This concentration of Ozone, if exceeded, is very harmful.

It can harm people, surroundings, plants, etc. Moreover, some ionizers also use Ozone (O3) into the atmosphere to counteract the pollutants.
So, before considering Air Ionizer make sure to check the ozone level they generate.

What Type of Air Ionization Technologies are Available in the Market?

Although all ionizers release negative ions into the air, all ionizers do not have the same technology. Here is some common type of air ionization technologies which include but not limited to the following:

UV Stick Lights

These types of ionizers cannot be classified as iconic units because they don’t emit ions. These devices throw UV rays on the surface of contaminants which cause damage to their DNA. As a result, they stop production and die quickly.

Electrostatic Precipitators

These ionization units have corona discharge through which they emit ions into the air. The fluid ionization within it causes this electrical discharge. The released negative ions then stick to the airborne particles which are then collected in an oppositely charged plate of the ionizer.

Ion Generators

These are more versatile devices that are available as stand-alone ionizers. Some ion generators may also have build-in regular air purifier features. The ions in these units are produced through corona discharge or UV light and in most of these units collecting plate is not present. When the charged particles of pollutants become too heavy, they fall off on the ground, bed, carpets, walls, and other things. And you often need to do the cleaning to remove them from your space.

Ozone Generators

You may already have heard about ozone which is a protective layer around the earth. It means that ozone ions occur naturally in our surroundings. Even the modest levels of ozone help in the effective neutralization of odors. The ozone generator units that emit a combination of low ozone ions concentration and others into the air are effective for regular cleaning of household air. Using a higher concentration of ozone ions is effective for removing strong odors like smoke or remediation clean-up.

Needle Point Ionizers

When the electric voltage is passed through the brushed metal needles, it produces a high concentration of active negative ions. These travel through the indoor air to attract pollutant particles in the air which gain weight and settle down on surfaces like floor, furnishings, etc. While needlepoint ionizers are highly effective for removing smoke without affecting airflow, the ions they generate have a brief life span. They cannot circulate and purify your entire home or purify walls, floors, and other surfaces.

Bipolar Ionization

This is the most advanced ionization technology that uses a combination of both positive and negative ions which attract contaminants with opposite charges. This builds-up heavy clumps of pollutants that fall down, purifying the air. These devices are effective for deactivating single-celled and carbon-based microbes like viruses, bacteria, and fungi.

The 11 Best Air Ionizers Buying Guide

By now you have understood air ionizers, how they work, their types, and benefits. Now you might have made your purchase decision. To help you in selecting the best negative ionizers, we have compiled a list of 10 most popular ionizer units outlining their features, pros, and cons.

Why Choose  Air Ionizers over Air Purifiers?

There are several benefits of choosing negative air ionizers over conventional air purifiers. However, the major difference is in the way they remove airborne particles from your environment.

The HEPA air purifier is designed to pull the air into its unit. It then circulates that air through a premium quality filter that captures pollutants. Once it circulates and cleans the air, the air purifier throws back the filtered air back into the indoor environment. The captured pollutant particles stay strapped within the filter securely until the time comes to change it.

Air ionizer, on the other hand, does not have filters for trapping the airborne impurities. It releases electrically charged ions into the air. These ions attach to the airborne particles and weigh them down and then attract them to the charged plate where they fall or they fall on the floor or walls. The homeowner can either clean them from the walls and floors or replace or wipe clean the collection plate. This device requires regular cleaning to prevent the emission of particles back into the air.

Enhanced Physiological Well-Being

People who suffer from seasonal allergies, hay fever, asthma, etc. can harness the benefits of these environment cleaning devices. The studies show that negative ions have remarkable physiological effects including a decrease in blood pressure, rate of respiration, increased well-being and resistance to infectious diseases, reduction in skin temperature, and many more.

Improved Indoor Air Quality

The new generation of ion generators has a significant impact on indoor air quality. It not only cleans indoor air but also sanitizes it. Studies suggest that harmful pollutants in the air such as germs, bacteria, molds, volatile chemical compounds, etc. are effectively reduced with the use of the best air ionizers.

Reduce Stress and Boost Immune System

A literature review of various studies conducted in 2018 found that negative ions have many positive effects on human health and psychological well-being. There can be a variety of different reasons why these problems arise like air-condition side effects. Studies showed that these ions help in reducing stress, boosting the immune system, helps in the regulation of sleep patterns, enhance metabolism, and inhibit harmful bacterial growth.

Are Air Ionizers Really Effective?

The type of air ionizer you are using determines its effectiveness. The ionizer units with collections plates are much more effective as compared to the ones that do not have these plates. It is because the plates allow these units to gather pollutants and prevent them from going back into the air. While those without collecting plates leave the pollutants back into the air.

If you have an air ionizer without collecting plates, the effectiveness of the unit depends on you. If you rarely clean the area and spaces in which you are using ionizer, you won’t feel much difference in the air quality. To know more about air quality and it’s factors you can read our blog.

Most of the negative air ionizers cover an area of up to 600sq.ft however there are some best air ionizers available in the market which covers areas as large as 2000sq.ft.
