Who is this for?An ionic air purifier is for everyone, including pets that need clean indoor air. However, it works best on adults with fully developed respiratory systems. Baby, infants, and toddlers with developing respiratory systems will not reap the full benefit of a negative ion generator. The same limitation applies to elderly or sick patients suffering from impaired respiratory systems.

How Do We Measure?
Purchasing the right ionic air purifier can be challenging as there are a lot of knock-offs and ozone generators masking as an ionizer. To help you bypass all the fake models, here are the features that are a must in an ionic air purifier. Never consider an air ionizer that fails to disclose its specification.
- Room size - A critical factor to account for the room size an ionizer is capable of covering. Get the figures via the manufacturer's recommended room size or CADR. You will need more than 1 unit if the ionic air purifier lacks the capacity to cover the entire space.
- No ozone - Stay away from a model that generates harmful ozone to clean the air. It is unsafe, unregulated, and not recommended by EPA.
- Addon filtration - An ionic air purifier will work best with the support of a True HEPA filter that traps fine particles and allergens. For smoke particles, having an activated carbon filter can help get rid of toxic fumes.
- Noise output - Not the biggest concern as dedicated ionizers produce little to zero noise during operational hours. For HEPA air purifiers with an ionizer, the sweet spot is between 20 dB to 60 dB.
- Power consumption - Air purifiers are not power-hungry. You can still go with an Energy Star certified model that guarantees 40 percent more energy-efficient than similar segment models.
- Features - Nothing wrong with having more features in an ionizer. Choose from a timer, sensor, auto mode, sleep mode, child lock, and remote control.
- Pricing - Only buy an ionic air purifier you can afford to own and maintain. Disposable replacement filters can be a burden as a recurring cost. Consider a filterless ionizer if you are tight on budget.

- Lifetime warranty.
- No carbon filter (default).
- Can't run without filters.
Alen BreatheSmart 45i is the best ionizer for home with a medical-grade HEPA filter. It is equipped with customizable filters that suit people with compromised respiratory. The full-size machine comes in at 17.8 x 26.8 x 10 inches in dimension and a heavy weight of 21 pounds. Indeed not the model for those with limited room spaces or multi-location use.
If money is no biggie, this is undoubtedly the best HEPA ionic air purifier for home. Period.
Design-wise, Alen BreatheSmart 45i has plenty to offer with its customizable panel. You can choose any color, pattern, or limited edition to suit your modern interior. For assessment, you will also find an air quality indicator that illuminates blue (clean air), yellow, or red light (bad air). Build quality is exceptional, as evidenced by Alen's lifetime warranty (with subscription).
Usability is great with the 4 fan speeds and SmartSensor technology. Auto mode works well with the built-in sensor that accurately detects nearby pollutants for quick changes. The Advanced Smart Filter measures the filter life in real time rather than a fixed period. The highlight of it all is the Ion button that enables ionization. There is also a 4, 8, 12 hours timer and child lock function on top of the long list we mentioned.
Here are Alen Classic BreatheSmart specification:
- Main filtration - Ionizer, Washable Pre-filter, HEPA-Pure Filter BF35
- Chemical-free - Yes
- Ozone-free - Yes
- Warranty - Lifetime
Regardless of which filter pack you choose, Alen BreatheSmart 45i comes with an ionizer by default. It emits millions of negative ions in a room that bind with positive ion particles. The charged particles will gradually fall from the air for the all-in-one filter to capture. The washable pre-filter will be in charge of trapping dusty, large particles, while the HEPA filter removes 99.97% of airborne particulates as small as 0.1 microns. If you opt for HEPA-Silver, HEPA-FreshPlus, or HEPA-OdorCell filter upgrade, there is an additional deodorization filter to absorb chemical fumes, smoke, and musty odor.
Here's where Alen BreatheSmart 45i shine. The 190 cfm airflow delivery rate allows a wide room coverage of up to 800 square footage. Ideal for large room sizes like a living room, basement, garage, kitchen, or an entire apartment as long as you keep the door open. CADR is measured at 245 cfm for dust, pollen, and smoke. Note that the test does not account for ionizer output, so use it sparingly.
Moving from speed to noise, Alen BreatheSmart 45i is not the most subtle model at an average of 42-56 dB noise output. This is partly due to the strong air flow generated from the spinning fan. If you need a 100% silent unit, you're better off with a dedicated air ionizer. Energy usage is also on the higher side, given its high performance at 64-105 watts output per hour. We highly recommend you leave it in Auto mode and let Alen BreatheSmart manage the energy usage by itself.
For setbacks, Alen BreatheSmart 45i can be summarized with one word: Expensive. From the selling price to the customizable panel and filter, any add-ons will cost you money. On top of that, the HEPA-Pure filter does not come with a carbon filter for smoke filtration. A top-up of 10-40 dollars is needed for the upgraded filter (recommend). You will also need to account for the recurring filter cost, as the ionizer will not work without it.
In short: If money is no biggie, this is undoubtedly the best HEPA ionic air purifier for home. Period.

6. Fellowes AeraMax 100/ DX5 Air Purifier
- Under 20 dollars.
- Negative ion generator.
- Compact, plug and play setup.
- Ozone-free, radiation safe.
- Quiet and economical.
- Very small cleaning coverage.
- Needs further vacuuming.
- Weak against dust, smoke, odor.
An ionic HEPA air purifier that improves indoor air quality instantaneously. Fellowes AeraMax 100 or DX5 in some regions stands "tall" than other air ionizers listed here. Its modern approach is a breath of fresh air from the usual style at a slim 7.3 inches in depth, 27.3 inches in height, and 8.5 inches in width. You can place it anywhere in the home as the tower form factor with side air inlets takes up very little interior space. The reasonably light 9.9 pounds weight enables easy grabbing on the back handle for room-to-room purifying. Build quality is outstanding despite the plasticky body. No uneven gaps or protruding cases that are visible to the eyes. The 3-year warranty is the biggest assurance of its reliability.
For under 120 after a discount, Fellowes AeraMax100 tower air purifier is quite a bargain if you want mechanical + ionization filtration in a smaller form factor.
Control-wise, Fellowes AeraMax DX5/ 100 is made easy, thanks to the digital display. You can manage your desired fan speed or enables Auto mode via AeraSmart Sensor. The air cleaner will automatically set to a higher fan speed when elevated pollutants are detected and revert to low when the air is clean. Aera+ mode is identical to Turbo, which allows swift allergens removal. There is also an AQI to display the surrounding air quality and a filter change indicator reminding you to replace the filter when the time is up.
Being a tower air cleaner, Fellowes Aeramax 100 air purifier has a modest air cleaning output of 100 square feet of space with or without the PlasmaTRUE ionizer. Not the greatest, but for small confined spaces like a bedroom, kitchen, dorm, studio, or nursery home, it is more than sufficient. Clean air delivery rate tally with the airflow delivery rate at 65 cfm for dust, 75 cfm for pollen, and 68 cfm for smoke. Again, not the greatest, but for home use, it's okay.
Fellowes AeraMax 100 air purifier uses PlasmaTRUE technology, a fancier name than an ionizer. It begins with the charcoal pre-filter traps large contaminants like dust, hair, and lint while also neutralizing smoke, toxic fumes, and smelly odor. Next, the True HEPA filter captures 99.97% of ultrafine particles in the air as small as 0.3 microns i.e. pollen, pet dander, bacteria, and viruses. The HEPA filter is coated with AeraSafe antimicrobial treatment that prevents microorganisms like mold growth. The highlight of the filtration, the PlasmaTrue ionizer generates an ionized field that merges positive ions in the air. The heavier pollutants will be pulled down for the filter to capture, and the endless cycle continues cleaning for any incoming contaminants. PlasmaTRUE technology is reusable, but the compulsory filter replacement cost is around $60 annually; high maintainable in the long run.
Noise level is not an issue with the Fellowes AeraMax 100 air purifier. Expect zero noise at low speed to mild noise with the PlasmaTRUE turned on. As no sleep mode is available, Auto mode is the go-to option for a relaxing night's use. As for power usage, Fellowes AeraMax 100 consumes 37 watts to 51 watts of electricity with an ionizer. With 12 hours of operation, the average electric cost will be $0.07 per day, $2 monthly, or $24 a year. It is worth noting that the Fellowes AeraMax 100 is not Energy Star Rated, unlike other higher-end variants e.g. AeraMax 300.
There is some trade-off with Fellowes AeraMax 100 air purifier mainly revolves around performance. It has an under-par purifying coverage and CADR compared with other HEPA air purifiers with an ionizer. The use of a charcoal pre-filter over a separate pre-filter and carbon filter is disappointing. The non-dimmable blue indicator light, perhaps, is the final straw for some. Still, we wholeheartedly recommend getting Fellowes AeraMax 100 as there is no better option for an allergy and asthma-friendly certified, AHAM-approved, ionic HEPA air purifier.
In short: For under 120 after a discount, Fellowes AeraMax100 tower air purifier is quite a bargain if you want mechanical + ionization filtration in a smaller form factor.

Belita Amy Plug In Air Purifier
A dedicated plug-in negative ion generator from a relatively unknown brand. Belita Amy ionic air purifier is well highlighted with a distinctive leafy design. Because of its pluggable form, you can easily pack it into a suitcase for travel or outstation. The low-price setup did not cut corners on its build quality. It is made with durable ABS materials that are tough enough for constant use without breaking apart.
Works straight out of the box; Belita Amy ionizer plug-and-play setup is very easy to get the hang on. Just find a U.S. wall outlet, plug it in and let it run autonomously. The energy-saving operation will not increase your electricity bill at all. There is also no noise, no ozone, and no chemicals to contend with. The perfect silent air ionizer.
Here is Belita Amy key specification:
- Main filtration – Negative ion generator
- Chemical-free – Yes
- Ozone-free – Yes
- Warranty – 1-year
Belita Amy is the next best thing to natural, forest-like air. It will emit 32 million negatively charged ions per second. The negative ions will bind with other airborne particles, causing them to fall from the increased weight. The cleaning circle will continue within its small range, so you should always place it close to the pollution sources.
Like all air ionizers, Belita does share its own set of flaws. Since it does not come with a metal rod or plate, you will have to perform vacuuming to remove the stuck pollutants on the surface area. While no maintenance is needed, the limited coverage requires you to get more than 1 unit just to cover a small space. We recommend using it as a secondary unit to an existing HEPA air purifier.
In short: An affordable, plug-in negative ion generator that is 100% chemical-free, ozone-free, and filterless. A good starter model.
How An Ionizer Works
An ionizer or ionic air purifier releases negative ions to generate a static charge around positive ions pollutants in the air. With the added weight, the charged particles will bond and fall to the nearest surface area e.g. wall, cabinet, bed, sofa, the floor. If a HEPA air purifier or electrostatic precipitator is present, it will draw in the fallen particles to the filter/ plate for capturing rather than letting the pollutants scatter all over the room. You can skip regular vacuuming and only perform routine maintenance on the device.
On the other hand, a HEPA air purifier relies on the density of the filter to trap pollutants that pass through its surface, leaving only clean, fresh air out. A true HEPA filter is certified by the U.S. Department of Energy (DOE) with an efficiency of 99.97% in capturing particles smaller than 0.3 μm in diameter.
Which Is Better, Air Purifier Or Ionizer?
It depends. Ionizers and air purifiers use different technology to improve indoor air quality. An air purifier equipped with a HEPA and carbon filter will do a better job cleaning the air because it can actually trap all types of pollutants inside a physical filter. Ideal for people with severe allergies, breathing issues, or asthma. The only downside is the filters can be expensive to replace and maintain.
An ionizer diffuses negative ions to pull down airborne pollutants in the air. It is much more cost-efficient because the ionizer is reusable and doesn't require a physical filter to work. However, the fallen pollutants will scatter all over the room and requires additional vacuuming. It is also less effective against large particles, smoke, and odor.
Why Do Ionizers Smell?
The burned, metallic smell is caused by the electrical charged negative ions discharge from an ionizer. The more charged ions clumped together, the more distinctive the smell will be. You will also experience such refreshing smells around waterfalls or mountains where negative ions occurred naturally.
How To Tell If An Ionic Air Purifier Is Working?
Purchase an air ion counter that measures the ion density in the air. Monitor the meter speed change from 1.1 kV charge dissipated to 0.1 kV indicates how well the ionizer operates in ions per cubic centimeter (ions/ cc). You can also tell if an ionic air purifier works by its distinctive, burned smell. The noticeable improvement in air quality indicates an ionizer is working, where you will breathe better with a happier mood. You will also experience less fatigue and fewer allergy reactions.
How Long Should I Keep An Ionizer On?
According to the user manual, an ionizer should be running 24 hours a day without shutting down. If that is not possible, you should keep it running for at least 5-8 hours a day and resume back operation when necessary.
What are the Benefits of Negative Ions?
There are a lot of health benefits from breathing in negative ions. Having the best ionic air purifier guarantees a constant flow of ionized air with no harmful byproducts to worry about. Here are the perks you will enjoy:
- Cleans air by reducing the number of particulate matter and bacteria in the air.
- Breathe easier with less respiratory irritation, like nasal congestion or inflammation.
- Prevent an asthma attack with fewer allergen triggers in the air.
- Negative ions produce biochemical reactions that increase the mood chemical serotonin level. You will feel better and happier throughout the day.
- Leaving an ionizer on all day can help you sleep better, relieve stress, boost concentration and energy levels.
- Negative ions can act as a specific antidepressant for people with seasonal affective disorder.
- Ease headaches and migraine.
Are Ionizers Safe? Is It Safe To Breathe Ionized Air?
Not only is inhaling negative ions safe for humans, you actually gain health benefits from breathing into ionized air. Negative ions stimulate the production of biochemical reactions that increase levels of the mood chemical serotonin, alleviate depression, relieve stress, and boost daytime energy. The charged negative ions emitted by air ionizers helps cleans the air by attracting airborne particles to fall for the filter to capture. You can also find negative ions naturally occurring in outdoor environments like sunshine, lighting, mountains, and waterfalls.
Do not confuse an ionic air purifier with an ozone generator. As highlighted in an EPA report, there are manufacturers mislabeling ozone generators as "ionizers" to mask the potential danger and backlash from the public. Rather than diffusing negative ions, an ozone generator emits millions of ozone, far exceeding the Food and Drug Administration (FDA) limit of 50 parts per billion (ppb). Inhaling ozone can lead to side effects such as cough, chest pain, shortness of breath, headache, and throat irritation. Chronic exposure to ozone can cause respiratory illnesses, permanent lung scarring (pulmonary fibrosis), asthma attacks, and reduced lung capacity with damaged tissue cells.
Why Are Ionic Air Purifiers Bad?
Ionic air purifiers are not dangerous; there is no need to use them cautiously as long as they are certified by CARB or come from a reputable brand. However, ionizers do produce ozone during the electric charging, but at a very insignificant level, not exceeding CARB and FDA ozone emission limits. You can visit the CARB website or look closely at the air purifier's technical specifications and find out the ozone output.
Do Air Ionizers Work For Covid?
When used correctly, ion air purifiers can help reduce allergens in the air, including Covid viruses. However, an air ionizer by itself is not enough to protect people from getting COVID-19. Safety precaution steps such as social distancing and wearing a mask is still recommended.
Do Ionizers Remove Smoke And Odor?
An ionizer does not directly remove smoke odors. However, it can control and contain the harmful particles causing the smells. The release of electrical charges will clump airborne pollutants and drag them down to a surface area, reducing the spread of the odors. You will need an air purifier with an activated carbon filter to effectively remove gaseous pollutants like wood, tobacco, marijuana, mold, and burning fuels.
To recap, an ionic air purifier works best when combined with HEPA and carbon filtration. Go with hOmeLabs 4-in-1 Compact when you're on a budget, Medify MA-40 Air Purifier for the best ionization performance, and PureZone Elite for the best overall. For those that prefer the purest, 100% mechanical filtration with absolutely no ozone byproducts, check out our handpicked, best ozone-free air purifier list.
