Air Ionizer Overview

What are Air Ionizers?

Air Ionizers are used to purify the air in your home. Through the positively or negatively charged ion particles in the air of your home, Air Ionizers create more negative ions in the air. These negative ions are highly charged and can be spread about the rooms of your home with fans within the home air ionizers themselves.

How do Air Ionizers work?

The negative-charged ions attract contaminants that may be floating around the air of your home, negatively affecting the air that you breath and possibly making you sick. These contaminants that home air ionizers attract and then eliminate are nasty particles such as mold spores, dust mites, and other particulates, microbes, and odors from the air. This gives your home a more pleasant smell and a healthier environment to be breathing in.

Who uses Air Ionizers?

Many people with allergies and severe respiratory conditions use home air ionizers to increase the quality of the air they breathe and, ultimately, their standard of life. But it doesn’t take a sensitive person to recognize the large amount of debris, dust, spores, motes, hair, and skin cells along with all the other air particulates that pollute the very air we are breathing every day, whether you’re awake or asleep. The next time a ray of sunshine is peeking through your window, take a look at just how poor your air quality is, you may be shocked.

Why would you use an Air Ionizer?

Using a home air ionizer is all about increasing indoor air quality. While room air conditioners cool your room, ceiling fans circulate the air in your room, vanilla candles change the scent in your home and HEPA Air Purifiers help purify the air in your room, there are few products on the market that increase indoor air quality like home air ionizers, with some ionizers featuring the ability to get rid of particles that are .01 microns in size!

This list of the best Ionizers aims to highlight some differences in design and price point to give you the best ionizer within your budget. The design of these home air ionizers all work on some basic principles:

  1. Air is charged with negative ions:

The ionizer creates negatively charged air ions with electricity that in turn attracts the particulates that may be floating around your house (dust, mold spores, bacteria, hair, etc.).

2. Charged Ions get Heavy

Heavy Charged Ions collect the particulates and either fall to the ground or are collected on collections plates, which can be washed.

3. No Air Filters

Unlike other air filter technology, home air ionizers do not require costly air filters to be continually replaced. The device is all you need with the possibility of cleaning the collection plates if it comes with that option.

4.5 out of 5 stars

Airthereal MA10K-PRO Air Ionizer Review

Airthereal is a household name in air purification and this product is the most cost-effective home air ionizer on the market. The MA10K-PRO Ozone Generator is a High Capacity air ionizer, meaning it produces over 10000 mg/h of ozone. Though this may be less than other products on the market, this is still a large amount of ozone output for an air ionizer, putting it in the high capacity category.

Just like other products, the technology is safe: the device has a timer and fan that gives an output of ionized air that is negatively charged into the home, farm or office where it is situated. These negatively charged ions that come out of the home air ionizer attract particulates which can cause humans respiratory, the worst being mold spores, severe dust motes and tiny particulates some smaller than the tip of a human hair.

The Airthereal MA10K-PRO also has a timer that can make it run for up to 120 minutes and a durable plastic handle that folds down and is form-fitted for carrying from place to place within your house, farm, office or warehouse. Just like other products, its high capacity output of ionized air makes it ideal for cleanups with fire damage and water damage that may cause smoke damage or mold spores to be growing.

The biggest and best difference that sets the Airthereal apart from other manufacturers is that the company stands behind its products thoroughly. Airthereal stands behind each home air ionizer with a 3-year warranty for the entire device and 5 years or 20,000 hours of use for the ozone producing plates within the ionizer. Given the recommendation of using this device 120 minutes twice a week, these guarantees are steadfast and make it an iron giant in the industry of home air purification and cleaning.

Enerzen COMINHKG102506 Air Ionizer Review

With over 100,000 units sold, the Enerzen High Capacity Commercial Ozone Generator is part of a line of air quality indicators and devices by Enerzen with a high turnover. One benefit of this is that each batch is typically made within the last two months and has a great track record of being up to date and reliable. The large fan, stainless steel filter and 180 minute timer make this industrial-sized air ionizer an air purifier, deodorizer, and sterilizer, capable of being used on the biggest projects for your home and business.

This easily accessible and portable design comes in a powder blue industrial-grade aluminum casing with a black plastic folding handle. The durable handle makes moving this air ionizer an easy task. Few air ionizers for home use compare to the output of the Enerzer High Capacity Commercial Ozone Generator with its 11,000mg per hour output.

The only thing that this air ionizer lacks is the ability to capture heavy particulate matter. Instead, this design relies on the heavy particles to fall to the ground after they have been charged negatively by the ionizer. Once negatively-charged, the particles become heavier than air, forcing them to the ground.

This home air ionizer is also CE and RoHS -certified, meaning that it conforms with health, product safety, and environmental protection standards.

Keep in mind the price point is similar to other models that may have less output, but have catch plates that can be cleaned.

TREKOO Air Purifier Home Air Ionizer Review

A solid space-saving option at a mid-range price is the Trekoo Air Purifier for home air ionization. Like other ozone and home air ionizers, the Trekoo Air Purifier is adept at negatively charging ions in the air of your home, restaurant, office or restroom and capturing odor at its source.

The elimination of particulates and odor-causing pollutants that can also negatively affect respiratory health is the main claim of this device. With its auto-sensor, this room air ionizer can detect when pets or people are in the room and will turn on a 2-minute cycle every 4 minutes. When there is nobody detected in the room, the home air ionizer from TREKOO will switch to sleep mode which pauses functionality and puts the air ionization on standby. It then turns it back on after 2 hours.

The lightweight and flat design also makes the TREKOO Air Ionizer a great option to tuck away in the corner of a room, restaurant, office or restroom. Because it’s flat and has panels to mount, it can even be hung from the wall.

The TREKOO Air Purifier is compatible with power outputs from 100-240 volts and has an output of 10 volts.

Air Ionizer Buying Guide – What is an Air Ionizer and why you may need one

Everyone knows the popular saying “You are what you eat”. It’s meant to raise a concern about your health and what you’re putting into your body. Well, what about the air we breathe in? Shouldn’t this also be of some concern for the average person?

Luckily science has provided us with a solution to this common household issue. Air Ionizers can help to create a clean and fresh environment in your home. Free from any dust, dander, or any other airborne pollutants lowering the quality of the air you breathe.

How Does an Air Ionizer Work

A high amount of electricity is made to flow through a series of small needles inside your air ionizer. In effect, this creates electrons that spill out into the air surrounding your air ionizer. As those electrons move about, they’re attracted to all the dust, dander, and irritants. They form bonds with the ions inside those irritants, changing them into negatively charged ions. This allows the air pollutants to then attract each other, and form large enough compounds to be caught by your Air Ionizers filtration system.

Unlike other air purifiers, Air Ionizers are easy to clean, and their filtration systems are reusable. A simple cleaning with a wet rag can rejuvenate your air ionizer and get your breathing clean again.

Popular Uses and Features for Air Ionizers


Anyone with allergies can tell you how much they dread the coming allergy season. Allergies have become a big reason people have begun investing more in Air Ionizers. The negatively charged pollen is made easy to capture by filtration, and hence making it easier for you to breath.

Household Pets

Though we love our furry friends, they can also add to the laundry list of allergies in your home. Not to mention the often occasional unpleasant odor. An Ionizer can help to keep these offending odors away by refreshing the air in your home and removing them completely. As ozone is a byproduct of creating electrons, the ozone can help to neutralize odors as well. But, it’s important to keep in mind the amount of ozone being created by your Air Ionizer. Too much of the stuff can be harmful.

Healthy Air Quality

Many users have reported they feel more energized and inspired while using an ionizer. This is no mere coincidence. The negative ions produced as a result of you purifying the air around you is similar to other naturally occurring events. Negative ions are released in a similar fashion around waterfalls, ocean surf, or those few precious moments following a rainfall. Imagine what having the positive effects of a waterfall in your home could do for you.

Bacteria Naturalization

Some Air Ionizers come with a UV Light feature that destroys harmful bacteria on contact. That cool blue light does more than add some flair to the room. It’s playing gatekeeper by killing all the hitchhikers present on floating dust particles. Though not all air ionizers come equipped with UV Light, it is an added benefit to keeping the air in your home happy and healthy.
