Compared to the concept of air pollution being limited to outdoor sites; the indoor air is not any better! As per the EPA, indoor air pollutants’ levels are sometimes 2-5 times higher than outdoor ones. Nevertheless, indoor air being limited can be treated comparably to the pollution type using a good air ionizer.

Since people need to breathe healthy and pure indoor air, the popularity of air ionizers is increasing. Let’s discuss what precisely an air ionizer is, how it works, and how it benefits your place, so you can boost the air quality in your house.

What Is An Air Ionizer?

Two basic types of ionizers are available in the market:

1. Electrostatic Precipitator – It comes with an additional collector plate that gathers the drop contaminants instead of leaving them covering the place. This procedure of purification is environment-friendly hence you can use the plate repeatedly.

2. Air Purifier With An Ionizer – An air ionizer is also known as an ion generator, ionic air purifier, or negative ion air purifier. This device cleans the air by emitting 20,000 and 200,000 ions every second for reducing airborne particulates.

It pulls in and captures discharged ions onto the filter. Maximum HEPA filters cannot be used again, but they are proven to be more efficient capturing the discharged. A few ionizers create a very little amount of ozone that can be overlooked safely.

Since people are told to breathe healthy and pure indoor air, the popularity of air ionizers is increasing. After all, this device contributes to enhancing the air quality of your house.

Although particle-based air purifiers are known as the most demanding ones due to their efficient performance, air ionizers are sometimes seen complementing them as an extra filtration phase.

Let us have a look at some basic advantages of an air ionizer:

  • Works amazingly in removing such viruses and bacteria from the air, which are very small.
  • Does not demand lots of maintenance, for example, yearly replacement of filters.
  • Lowers static electricity by fixing the imbalance between negative and positive ions in the atmosphere.
  • Helpful for people who have the sensitivity to chemicals, asthma, and pollen or dust allergies because they can remove all kinds of viruses and bacteria from their household, incorporating chemical toxins, odors, smoke, pet dander, dust, mold, and pollens.
  • Works perfectly in fighting exhaustion and keeping you recharged, again because of the existence of more negative ions in the surrounding.
  • Activates positive mood, reduces possibilities of hypertension, and lowers stress levels, due to the generation of more negative ions around.
  • Improves immunity to help us fight infections.
  • Enhances our sleep quality by purifying the air of all unnecessary pollutants while we sleep at night.
  • Enhances the whole wellbeing, i.e. it is psychological, emotional, mental, and physical.
  • Lowers the chances of daily perpetual headaches in people who are directly exposed to computer screens for work.

The ionizing air purifier can do a lot for the indoor air. It can expel microbes like germs, viruses, and mold spores from the air. These ionic air cleaners work as air fresheners that neutralize odor from cigarettes, pets, and also cooking smells for producing a cleaner home ambiance.

Unlike conventional HEPA filters that catch suspended pollutants mechanically, an air ionizer utilizes electricity for discharging negatively charged ions into the air. These negative ions hold neutral airborne particles hence charging them.

When charged, these pollutants are likely to clot and are attracted to the collector plate that is oppositely charged. Rather, in case the air cleaner’s design incorporates a physical filter, the charged particles are caught in the filter, which makes the airflow clean.

Air ionizers are different from other traditional air purifiers available in the market, which utilize filters and fans for removing pollutants from the air. From the working strategy of ionizers, it can be understood that these work amazingly for fine airborne particles incorporating a few species of viruses and bacteria.

Nevertheless, compared to a famous concept, these don’t help with odors and gaseous pollutants. A tiny amount of ozone created in the procedure may cover the odor, but it does not reduce it as an activated carbon filter does.


For purifying the air that we breathe in our houses, air ionizers may be a comparatively newer concept.

However, they have obtained fast popularity within a short period. This is evident from the range of their utilization in not only houses but also schools and hospitals to boost the health quality of students and patients, respectively.

So, this is the right time to install them in your households and reap all the advantages of breathing healthy air and staying fit.
