The Best Air Purifier That Generates Beneficial Negative Ions

Are you thinking of getting an air purifier for your home? While there are plenty of air purifiers out there, ionic air purifiers are a great choice. They’re able to efficiently clean the air in your room and aren’t overly expensive. The best ionic air purifier, in the end, depends on your individual needs.

Ionic air purifiers

Let’s Take a Look at Ionic air purifiers

Ionic air purifiers are built with special negative ion generators. How it works is that these generators send out a stream of negative ions that are attracted to the positive airborne particles within the air. As a result, these negative ions end up joining with the positive particles in the air and cause these particles to become “heavy”. Eventually, they’ll end up falling to the floor because of their own weight – thus eliminating them from the air.

Simply put, ionic air purifiers use electricity to charge the spores along with the dust particles in the air. These particles then either drop to the surfaces in your home or are drawn to a collection plate that’s situated inside the air purifiers. If you’re getting an ionic air purifier with a collection plate, you must wipe down the plate regularly for the ionic air purifier to work effectively.

When choosing your ionic air purifier, there are a few things you’d need to take into consideration such as the maximum room size that the ionic air purifier will work in, along with the dimensions of the machine. After all, the last thing you’d want is an overly bulky machine that’ll take up too much space in your home. Below are six of the best ionic air purifiers that we’ve found on the market to get you started.

Best Type of Air Purifiers

There are two major categories in discussion here: ionizers and HEPA air purifiers, so let’s understand how each of them works.

  • A HEPA air purifier has a filter with a material that traps contaminants onto its surface, anything from smoke to dust. These particles are common allergens and pose a real problem for people with respiratory problems, children, and elders. An air purifier certified by the U.S. Department of Energy can usually remove about 99.97 percent of particles with a diameter of at least 3 microns.
  • Ionizers have a different way to function. They release negatively-charged ions into the room, particles that bind to objects in the room and clean the air. Depending on the ionizer in question, it can also give an electric charge to these particles. This makes ionizers efficient in removing small contaminants from the air, but a lot of people consider them less efficient when compared to a HEPA air purifier when it comes to trapping larger contaminants.

Benefits of Negative Ions

To understand more about why ionic air purifiers are good, let’s look over some of the potential benefits that negative ions bring:

  • When there are high concentrations of negative ions in the air, it decreases the amount of airborne bacteria.
  • It can help with respiratory problems caused by irritation or inflammation.
  • Studies have revealed the fact that exposure to negative ions helps with Seasonal Affective Disorder.
  • Ion air purifiers help clean the air of mold spored, dust, pet dander, dust, pollen, etc.
  • They can reduce allergens that cause asthma attacks.
  • According to a French study, exposure to negative ions can help you sleep better.
  • Norwich Union revealed that installing air purifiers based on ion technologies help reduce headaches in an office.
  • They can also help improve performance and increase one’s capacity to concentrate on tasks.

How to Choose an Ionic air purifier

There are a few non-negotiable features that an air purifier needs to have, alongside a number of other specifications that you need to take into consideration before purchasing such a product:

  • When you buy an air purifier, you need to make sure it has the minimum required certifications. The Energy Star logo is one of them, and this is a label that attests an purifier is energy efficient because this is, after all, a machine that needs to run all the time. An Energy Star purifier is 40 percent more efficient compared to models that don’t have this certification. The AHAM Verified seal has been attested by the Association of Home Appliance Manufacturers, and that means that an aurifier has clean air delivery rates.
  • The size of the room is a factor to take into consideration before buying an air purifier. Units are designed to be efficient for a given amount of space, which means that a low-capacity purifier won’t do a good job in a large room. If you find a product that has the AHAM Verifide seal, you can rest assured that the unit is capable of covering the space it claims to cover.
  • Replacement filters are a consumable with a cost that you have to take into account. Purifiers that use activated carbon filters will require new ones every three months, while pleated filters require changing every six to 12 months. The cost of these filters is important because it’s a long term commitment cost, and the price between filters varies from $20 to $200.
  • The noise level of an air purifier is really important if you have to listen to it all the time, and especially if you use it in the bedroom and you’re a light sleeper.
  • Filters with air quality sensors will tell you how polluted the air is and you can make the required efficiency settings accordingly.
  • Having an air purifier with remote control is recommended for your own comfort, but it is not mandatory in running the unit. They just allow you to fiddle with the settings without having to get up.

Ionic Air Purifiers vs. HEPA Air Purifiers

Ionic Air Purifiers vs. HEPA Air Purifiers

Occasionally, what appears to be an ionic air cleaner is actually an ozone generator. Examine the facts carefully to ensure you are not acquiring one of these. While makers claim they can be extremely successful in removing pollutants from the air, such as lingering cigarette smoke, they will not improve your air and are unsafe to have around.

Ozone generators create ozone, a gas that is a derivative of oxygen. In comparison to the oxygen we breathe, which contains two oxygen atoms per molecule, ozone contains three oxygen atoms per molecule. This seemingly insignificant alteration has a profound effect.

Ozone can irritate the lungs and airways, and people who already suffer from emphysema, asthma, or other respiratory disorders may notice their symptoms intensify as a result of exposure.

Ionic purifiers have this entire science behind them that might sound confusing to some, but that’s not the case with HEPA filters, as they are considerably more practical. When it comes down to it, HEPA filters are just what they sound like: a High Efficiency Particulate Air filter.

A HEPA filter must be capable of removing 99.97 percent of particles 0.3 microns in diameter or larger from the air it filters. Unlike air ionizers, a HEPA filter requires air to be pushed through it, which requires the use of a fan. This means they will not remain completely silent.

What Does an Air Purifier Do?View in gallery

What Does an Air Purifier Do?

Air purifiers operate primarily by cleaning the air, which could be contaminated with toxins, allergens, and pollutants. They operate in a different manner than filters.

The precise particles eliminated by an air purifier are ultimately determined by the purifier in question, as not all models operate with similar efficiency. Certain models include filters to catch particles as air passes through the system, with other models being focused on neutralizing airborne particles and doesn’t filter them first.

Are Air Purifiers Worth It?

Yes, provided you understand the limitations. They won’t purify every little thing that can contaminate the air, but they do a pretty good job against allergens, mold, smoke, and indoor toxins (from personal care to cleaning products). 

Do Air Purifiers Help with Covid?

The role of an air purifier is to filter airborne contaminants and pollutants from the air that passes through them. Consequently, they can aid in the fight against some viruses that are carried through the air. 

The proper use of air purifiers can help minimize airborne pollutants such as viruses in small areas. Air cleaning or filtration alone will not protect individuals against COVID-19. 

However, they are good measures to take in order t o limit the risk for COVID-19 airborne transmission indoors in enclosed areas when used in conjunction with other best practices advised by the CDC and other public health authorities, such as social distance and wearing a mask.

Do Air Purifiers Help with Dust?

All of these microscopic particles float through the air and eventually rest in a convenient location in our home. By installing an air purifier in a room, many of these particles will be captured before they have a chance to settle, not only improving the quality of the air but also minimizing dust accumulation on our tabletops, bookshelves, and other surfaces.

An air purifier circulates the air in a room, and as it does so, it collects all of the microscopic particulate matter floating in it, which happens to include dust. Although the air easily passes past the filter, the particles become stuck in the fibers. 

These trapped particles are those that would have settled as dust on household surfaces or triggered allergic or asthmatic symptoms if inhaled. While an air purifier cannot totally eliminate particles, with frequent usage, it can significantly reduce household dust.

What Is a True HEPA Air Purifier?

True HEPA filters are the highest level for physical air filtration utilized by air purifiers. Furthermore, HEPA filters are used in a variety of applications, including vacuum cleaners, vehicles, and even aircraft. 

To be considered a True HEPA filter, however, one HEPA air filter must be certified to remove 99.97 percent of all microscopic particles which can be as small 0.3 microns in size. 

As a consequence, a true HEPA air purifier is one that uses this specific type of filter and is considered to be one of the most efficient air purifiers on the market. 


Do ionic air purifiers really work?

Yes, but you need an ionic air purifier that’s strong enough and is compatible with the room surface that you’re trying to cover.

Are ionic air purifiers safe?

Most models that you can currently find on the market are safe, but if an ionic air purifier were to be too powerful, it would technically become an ozone generator, which is considered to be harmful.

What is the best ionic air purifier?

The best ionic air purifier is the one that meets the standards we talked about earlier. It needs to be energy efficient, be compatible with the room size you’re trying to cover, and come with all the features that you need to get from such a product.

Which is better air purifier or ionizer?

There is no correct answer to this question because, while they are both meant to clean the air inside the room, the way in which air purifiers work is different compared to the modus operandi of ionizers. So, it really depends on their quality of the air inside your home and what pollutants you’re trying to get rid of.

The Bottom Line

The best ionic air purifier really just depends on your own personal preferences, your home, and your needs. As you can see, there’s something for everyone from models that run quieter than others, ones that are designed for large spaces, small rooms, and more. Just be sure to do your research, starting with this buying guide, and choose one that works best for you!
