Clean-smelling air is much more than a matter of comfort. Unpleasant odors, whether they originate from animals, cigarette smoke, food or moisture, signify the presence of allergens such as bacteria, mold, dander and volatile organic compounds. There are many types of air cleaners, including the growing-in-popularity air ionizer.

What Is an Air Ionizer, and How Does It Work?


You do have one negative ion generator at home. With its stream of hot water and steam, the shower is a good source of negative ions. However, in real-world applications, the air ionizer is an effective air filtration device used in air purifiers.

That’s probably why so many people need a shower to get out of bed in the morning. However, it is of no use in the rest of your home.

Negative ionizers, fortunately, have been developed as an even more efficient way of producing negatively-charged ions and receiving their benefits in any space you spend time in.

Some air purifiers don’t have the common True HEPA filter, instead they will use an ionizer to support the physical air filter, or work as the only air filtration method alone. 

An air ionizer is a device that uses high voltage electricity to create negative ions and electrically charge the air molecules.

Advantages of Air Ionizers

If you have allergies, asthma, or chemical sensitivities, ionic air purifiers can help you breathe easier by removing contaminants such as pollen, mold, dust, and pet dander, as well as viruses, smoke, odors, and chemical toxins.

So, how can such a simple mechanism have such a wide range of beneficial effects? Here’s what you need to know about ionizers and their advantages:

Air ionizers remove dangerous allergens such as dust, pet dander, pollen, and spores from the air within your room, allowing people with Asthma, allergies, and other respiratory problems to breathe safe, fresh air.

Another reason to consider purchasing these air cleaning devices is their ease of use, which is improving with the advancement of technology. Many of these advantages are available at a low cost, which is not more precious than your loved one’s health and life.

But be cautious! When you use Air Ionizers, which are also Ozone generators, you can get rid of bad odors in your home. Since ozone is a gas that is harmful to your respiratory system.

As a result, before ozone cleaning your room, you will need to remove the 3Ps: People, Pets, and Plants.

The more efficient an ionizer, such as one of these best ionic air purifiers, can produce, the more safe anions it can produce, and the wider its range.

Envion Ionic Turbo is a gadget you must have in your home if you want to live in a safe climate, among other great features.

No Need to Replace Filter

This air purifier’s maintenance costs are as minimal as they come. There is no need to change the filter, and all you need to do is clean it to get the most out of this air purifier. 

The dirt from the front-loading collection blade can be sucked up with a vacuum cleaner. You can also use water if there is too much dirt, but it is strongly recommended that you dry the air purifier before using it, or you risk electroshock.

Quiet Operation


The ionic pro turbo unit takes pride in having a machine that is extremely quiet. In reality, even at the maximum fan speed, the air purifier manages to remove about 99 percent of the air pollutants in your home thanks to its powerful ionic mechanism. 

The system works by sucking dirt and other pollutants through positively charged electrodes. These charged particles then bind themselves to dangerous allergens, smoke particles, bacteria, and other minor contaminants. Finally, the unit shows some of the best ionic air purifier performance.

Simple to Use

Many Envion air purifier reviews praise the device’s one-touch operation, energy efficiency, and a slew of other features designed to make your time with it as pleasant as possible.

#3 Airthereal APH260 Ionic Home Air Purifier


If you have pets, the only air purifier ionizer that comes to mind is one that is specifically designed for them. For example, the Airthereal APH260 can handle pet fur, dander, and odor. It also protects against viruses, spores, and bacteria, which is important for the best UV air purifier.

Speed & Power

The Airthereal APH260 Air Purifiers have a remarkable amount of power for such a low-cost device. It isn’t mind-blowing, but it does have a respectable CFM of about 150. You’d think it would make a lot of noise, but it doesn’t! The lowest setting, which also takes into account Sleep Mode, is about 25 decibels, while the highest is just under 50.

Technology Based on Anion

One of the most efficient and important features of this air purifier is anion technology. It is essentially an ion generator that produces ozone. It has also been studied and proven that it does not emit dangerous amounts of ozone. 

As a result, in addition to protection, you will benefit from ion air filtration technology. Ions are a powerful air purifier. They cling to airborne particles, making them heavier, or they cling to the particles within air purifiers, making them less efficient. 

This approach is ideal for people who need clean, fresh air in their rooms quickly.

Airthereal APH260 Design and Size

Compared to other airthereal purifiers, Airthereal is bigger, larger, and heavier.It stands 21.2 inches tall and 13 inches high, more than double the size of any Day Dawning model. It is not, however, chunkier since the depth is only 6.7 inches, which is less than the ADH80 model.

The Airthereal APH260 follows the same basic bottom-to-top air flow mechanism as any other budget air purifiers. Behind the front plate is an air intake with perforated holes to help minimize the size of contaminants.

A digital air quality index monitor, as well as the main control panel, can be found on the top of this air purifier.

Product Specifications:

  • Product Dimensions: 13 x 6.7 x 21.2 in
  • Product Weight: 10.4 Pounds
  • Product Color: White
  • HEPA Class: True HEPA
  • Filter Life: 6-8 months
  • Sensor: Particle sensor – PM 2.5
  • Room Coverage: 380 sq ft

#4 Medify Air MA-40 Large Room Ionic Air Purifier


Modern air purifiers are fairly efficient, but manufacturers are now putting a greater emphasis on aesthetics. The Medify MA-40 v2.0 Air Purifier is made by Medify Air, a Kickstarter company based in the United States that has released a number of attractive and efficient air purifiers in recent years.

After the MA-112 and MA-50 models, the Medify MA-40 v2.0 is the third highest coverage air purifier in Medify’s floor standing air purifier lineup. A 3-in-1 filter is included, as well as an optional ionizer. The 224 cfm CADR back-to-front air distribution design is ideal for an ordinary bedroom or even a living room.


The Medify MA-40 is a well-made air purifier with a high-quality plastic shell. Its shiny outer shell not only contributes to its attractiveness but also gives it a premium appearance and feel.

The purified air exits through the vent on the front wall. The air quality indicator is also located on this panel. These three lights—red, green, and blue—inform you about the air quality in your room in real time.

It’s amazing that Medify took the time to place these metrics front and center. You won’t have to walk to the air purifier to read the air quality data, unlike other models that have the air quality indicator at the end. Given that this device lacks a mobile phone app, this makes even more sense.

Setting up and Assembly

This air purifier was created with ease of use in mind right from the start. It’s nearly over, and the air filter kit is already installed. In our analysis, the Medify MA-40 receives a lot of good points because of this.

The filter is, however, protected from dust during storage and shipping by being wrapped in plastic. As a result, before plugging in the filter, you must first open the back panel and remove the wrapper.

Product Specifications: 

  • Filtration Technology: 3-in-1 Filter Package
  • HEPA Class: H13 True HEPA
  • Filter Life: 6 months (3000 hours)
  • Maximum CADR: 224 cubic feet per minute (cfm)
  • Room Coverage: 336 sq ft ( 8ft on ceilings)
  • Fan Speeds: 4 – including sleep mode
  • Noise Level: 46 – 66 dB(A)

#5 Green Air Encore Air Purifier with IonCLuster Technology


The Green Air Encore Air Purifier is much more than a show-stopping piece of equipment.

IonCluster technology is used in this premium air filter, and it takes a special approach to bacteria destruction. It also has a three-filter system that traps almost all contaminants and odors in the air. Because of its outstanding performance, the Association of Home Appliance Manufacturers has given this purifier a clean air distribution rating, or CADR, of 250.



While in Auto Mode, the Green Air Encore 2019 has air quality sensors that control the fan speed. Air quality metrics display the current condition of the air in real time.

This air purifier has a Fan Mode, a Sleep Mode, and a Night Mode for use at night, in addition to an Auto Mode. The latter two reduce energy waste while also ensuring that the machine runs quietly. 

Additionally, when Night Mode is activated, the light indicators are turned off to reduce light pollution. To top it off, the Encore 2019 has an automatic filter change indicator that lets you know when it’s time to swap the filters.

Sleek Design

This Green Air model has a sleek and stylish look. It has a metallic gold finish and electronic controls and filter shift indicators on the top of its rectangular body. The color of an LED cut-out on the upper right side of its body changes depending on the current state of air quality in your room. 

It’s not the most compact device out there, weighing 16 pounds and measuring 25” x 14” x 7.5”.However, since the manufacturer markets this product as an air purifier for large rooms, it should operate well in areas up to 1000 square feet.

Product Specifications:

  • Dimensions: 25” x 14” x 7.5”
  • Product Weight: 16 Lbs
  • Area Coverage: 1,000 sq. ft.

#6 Fellowes AeraMax 300 Ionic Air Purifier


People searching for the Best Air Purifier, specifically, the Best Ionic Air Purifier, are likely looking for a large room air purifier, and the Fellowes AeraMax 300 Ionic Air Purifier could be that purifier. In regards to providing a HEPA filter, it is also a portable air purifier that is both quiet and durable.

Although the AeraMax 300’s efficiency and design won’t impress high-end air purifier users, its high-quality air filtration system and specs make it a compelling choice for budget-conscious users. Since not all of its specifications are instantly comparable with those of other manufacturers, the air purifier falls short of excellence. 

AeraSmart Sensor

The sensor detects pollution levels in the air and changes the fan speed automatically to keep it clean.

Since we humans can only sense airborne allergens through our bodies, it’s generally too late to switch on the purifier by the time our only indicators (sneezing and coughing) kick in.

This sensor ensures that the air is clean at all times while also conserving electricity. Since the fan in this device is far from quiet, many people would find that running it on high all of the time is not an option.

The sensor adjusts the speed in response to air quality, making it a very useful function. By looking at the indicator, you can also determine the air quality.

Blue indicates clear air, amber indicates low air quality, and red indicates extremely polluted air.

Levels of Noise


Noise exposure varies from person to person. Unfortunately, when running on the highest level, this device appears to be very noisy.

Since it has a sensor that tells it when to change the fan speed, you can be startled awake by the sudden change in noise levels. Again, this is just an issue for light sleepers since a basement air filter is normally located far enough from the bedroom.

This is something that people who have guest rooms in the basement should be aware of. Another issue for sleepers is the inability to switch off the warning light.

This feature is a downside if you prefer to sleep in complete darkness.


  • Purification technology with four stages
  • a reasonable price
  • Allergy and asthma friendly
  • Simple operation and a sleek interface


  • When the fan is set to the highest level, it makes a lot of noise.
  • Indicators of poor air quality that cannot be switched off

#7 O-lon B-1000 Permanent Filter Ionic Air Purifier


If you’re looking for an air purifier that will help you avoid allergies and respiratory problems, an air purifier that works as an ionizer device could be a good option. 

The O-lon B-1000 Permanent Filter Ionic Air Purifier does a good job, and it does so while using very little energy. This air purifier is very effective at removing pet hair, dust, and various sized pollutants from the air in your space.

Electrostatic Technology 


Electrostatic technology is a simple and effective way to monitor dust and pollen particles in your home by attracting them with an electric charge and then guiding them into a filtration device. Dust and dirt particles are fully removed by the multiple filtration systems in the O-Ion unit. 

In this unit, dust filtration is performed in a procedural manner. A dust collector, a standard filtration method, and a highly efficient device that works best with electric filtration mechanisms are all included in the device.

In reality, the manufacturer claims that its systems are capable of working on even the smallest of surfaces. Many 0-Ion B-1000 reviews have consistently debunked the claim of 01 microns.


This device, which has the appearance of a small entertainment system, is arguably one of the best built air purifiers in its price range. However, as some 0-Ion B-1000 reports have shown, the unit isn’t the most durable or sturdiest. 

It’s also worth noting that this low customer satisfaction is despite the fact that the product is UV bulb rated and expected to last at least 10,000 hours. However, with a little care and attention now and then, the computer will undoubtedly serve you well for a long time.

Utilizes Ozone and Ionic Technology

One of the strongest air ionizers is the O-Ion B-1000. In the presence of oxygen, ionic filtrations operate by releasing negatively charged ions into the air, which cause dust clusters. Using electrostatic technology, these clusters can then be quickly attracted into the filtration device. 

Ozone technology, which is best known for destroying germs, deodorizing, and freshening homes, is also used in the 0-Ion system. Its ozone emission level is limited and EPA compliant, but that doesn’t stop people from being concerned about ozone-related health problems associated with its use.

Product Specifications:

  • Filter Type: UV-C and Electrostatic Ionizer Purification
  • Air Flow CFM: .01 micron
  • Maker-recommended Room Size: 100 square feet
  • Noise level: Moderate
  • Energy Star-rated: No
  • Power (in W): 50 W to 60 W from high to low
  • Remote Control Included?: No
  • Dimensions: 5.5x 6.5 x 17 in.
  • Weight: 3.8 pounds
  • Maker: O-Ion (B-1000)
  • Warranty: 3 year warranty


  • This device is small and built to operate silently, which it does admirably.
  • Low one-time cost and use of electricity. This unit uses 7.5W and is affordable.


  • Ozone is generated by the device. This air purifier produces a small amount of ozone, as stated in the fine print. 
  • Performance was mediocre. This purifier is only good for cleaning small areas. It can only be used in very confined spaces.

Buyer’s Guide

The air inside your home is often more toxic than the air outside. We spend the majority of our time indoors, so poor indoor air quality puts us at risk for a variety of illnesses.

An air purifier can help to produce cleaner, healthier air in your home or workplace, allowing you to breathe easier. Before you buy one, consider the following:

  • Do I Need An Air Purifier?
  • What Air Purifier Size Do I Require?
  • What Features Would I Require?
  • Where Can I Put My Purifier?
  • How Much Should Air Purifiers Be Repaired?

Quick Guidelines for Selecting an Air Purifier

  • Determine where you want to put your air purifier so you can choose the appropriate size.
  • Look for an air purifier that can filter out contaminants that are unique to your home or health requirements (removing pet dander or cigarette smoke, for example).
  • Comparing CADR scores, which indicate how well an air purifier removes various contaminants, is a good idea.
  • Choose an air purifier with a HEPA filter, which is the industry norm for indoor air purifiers.
  • Look at the noise levels (in decibels) in the product specifications. You may want a quieter air purifier depending on where you’ll be using it.
  • Calculate the cost of ongoing maintenance and power for the air purifier so you can prepare for it after the initial purchase.
  • If money isn’t an issue, skip the extra features like app integration.

Determine Your Room Size

The first step in screening out air purifiers is to determine how much room you want your system to clean. Small desktop air purifiers are ineffective in large living spaces, whereas bigger, heavy-duty air purifiers in your child’s bedroom can be overkill.

Looking at “air changes every hour” is one way to find the best fit. This metric may be included in the specifications of your air purifier. A smaller air purifier could turn over the air in a 350-square-foot room eight times per hour, but just four times per hour in a 700-square-foot room, which will help you understand how filtration works in practice.

Types of Pollutants

Many air purifiers are better than others at filtering out specific pollutants. If cigarette smoke is your primary concern, you may need a different system than someone who lives with a zoo’s worth of pets.

Air purifiers are graded on their ability to filter various pollutant sizes. While most air purifiers work in the same way, some are slightly better at collecting dust and dander than others (or vice versa).

If you’re concerned about odors, look for a purifier with an activated carbon filter.

Noise Level

Internal fans drag air through a set of filters in most air purifiers. Some of these fans are almost silent, particularly when set to low speeds. When you turn them on, they make a humming noise.

If you’re going to use your air purifier in a bedroom or a baby’s room, for example, you’ll want something that’s quiet even at higher speeds. In your device’s specifications, you’ll find noise-level levels measured in decibels.


Some air purifiers are more portable and lighter than others. The smallest air purifiers can be comfortably transferred from room to room and rest on a desk or shelf.

Be Positive with Negative Ions

The best air purifiers with ionizers have benefits as well as drawbacks. They work by generating negative ions that attach to positive particles. The particles become compact and too heavy to float once they are bonded together. Following that, the particles would fall to the nearest surface.

Despite the fact that they are often marketed to people with allergies or asthma, studies show that they aren’t as successful as they say. If you don’t have allergies but have a lot of fine dust in your home, an ionizer can be beneficial.
