15 Best Air Purifiers with Negative Ions
for November 2022

An air purifier with negative ion might sound a bit futuristic, but these machines are functional and can help boost the cleanliness of your home. They improve indoor air quality by removing dust, allergens, bacteria, odors, pollen, and other airborne particulates. They come in many different forms, including plug-in air purifiers, tabletop air purifiers, and whole-home air purifiers.

Air purifiers with negative ion release ions into the air that attract dust, bacteria, and other contaminants, causing them to adhere to the ion. When the particles are collected in a filter, they're easily removed. Unlike air scrubbers, which use negative ions to clean and then recirculate the air, negative ion air purifiers remove dirt and allergens from the air. They work by attracting the particles, which stick to the ion and are then collected in a filter.

We test air purifiers for their ability to remove dust, allergies, smoke, odors, bacteria, viruses, mold, and pet dander. We also evaluate ease of use and features, including air filtration, air purification filters, and noise level. We also factor in customer reviews, which are important as not all air purifiers are created equal. Here are the best air purifiers with negative ion that you can buy in 2022.

Clarifion - Negative Ion Generator with Highest Output (6 Pack) Filterless Mobile Ionizer Travel Air Purifier, Plug in, Eliminates: Pollutants, Allergens, Germs, Smoke, Bacteria, Pet Dander & More

Clarifion

Negative ions reduce allergy, asthma, and sinus symptoms by circulating air through a central fan that blows out a stream of tiny charged ions. The ions attach themselves to particles in the air and cause them to become electrically charged, similar to static electricity. The ions then flow into your lungs and body, neutralizing them.

This is a great little gadget that can provide cleaner air for dorms, and for people with allergies, asthma, and sinus problems. You may not notice a big difference when you first start using it, but over time, you'll definitely notice cleaner and fresher air. The Clarifion has a filterless design that passes air through a negative ion generator that generates millions of negative ions per second. That releases negative ions in the air to wipe out most allergens, odors, smoke, chemicals, mists, and bacteria. The Clarifion is unobtrusive, it won't take up much space, and it packs a big punch for such a small device. If you have allergies or asthma, it is definitely worth a buy.

AirTamer A310PMB Personal Rechargeable and Portable Air Purifier Negative Ion Generator, Proven Performance, Black with Leather Travel Case

AirTamer A310PMB Personal Rechargeable and Portable Air Purifier Negative Ion Generator

by AirTamer

The AirTamer A310PMB is a robust portable air purification system that works effectively. The A310PMB is powerful, quiet, and reliable, delivering an impressive amount of negative ions.

The AirTamer A310PMB is just the right size for traveling and is light and portable enough to carry in a tote bag or suitcase. Due to its small size, we were disappointed that the A310PMB doesn't produce enough negative ions to clean a room; we recommend pairing it with a more powerful air purifier like the $280 AirTamer A320PMB in larger rooms. Also, the electrophorus ionization technology it uses to create a negative-ion sphere isn't as effective at removing larger airborne pollutants, such as VOCs, as some competitors' ionizers. Still, it did a great job of neutralizing dust from the air and was the only air purifier we tested that got by without an ionizer. The air it produces looks clean and fresh, and it can help heavy smokers breathe easier with this simple device.

Ivation 5-in-1 HEPA Air Purifier & Ozone Generator, Ionizer & Deodorizer for Up to 3,700 Sq/Ft – Included HEPA, Carbon and Photocatalytic Filters, with UV Light and Negative Ion Generator

Ivation 5-in-1 HEPA Air Purifier & Ozone Generator

by Ivation

The Ivation 5-in-1 air purifier is ideal for small to mid-size rooms up to 3,700 square feet. The negative ion generator and UV lamp make this purifier really effective for allergen removal. It has a couple of limitations. Both the negative ion generator and UV lamp can be removed, reducing its effectiveness, and the ionizer draws power and has only a 9-hour lifespan.

The Ivation 5-in-1 Air Purifier & Ozone Generator offers some of the strongest performance among affordable, all-in-one purifiers that we tested. It does a great job of removing small particles, odors, and viruses from actual room air. The silver ion generator seems effective, but we didn't notice much in the way of odor reduction during the tests. The dust filter is big, though, and the unit does a fine job of circulating the air. The ionizer also releases cyanogen ions, which may help counteract odors, and the unit also has a light that doubles as a nightlight. Unfortunately, this air purification system is noisy and could use a larger, more responsive LED display on its control panel.

The Clarifion purifier is our top-pick for a healthier home, and the filterless design makes it a cinch to clean and maintain.

The Clarifion Negative Ion Generator Travel Air Purifier from 3M is the cheapest portable air purifier we tested, and it does a good job of removing particulates, mold spores, and bacteria. It comes with handy LED indicators that let you know when the purifier is on, in "midair," or in maintenance mode. The one caveat is that it's not as good at removing larger particles of dust, smoke, or dander from a room. It's also not super quiet, and it can get plenty warm when in use.

HAPHID Negative Ion Generator/Plug In Air Purifier with Highest Output - Up to 32 Million Negative Ions/Sec, Filterless Mobile Ionizer & Portable Purifier Clean:Pollutants,Odors,Pets Smell Etc(3 Pack,Silver )

HAPHID Negative Ion Generator/Plug In Air Purifier with Highest Output

by Haphid

The HAPHID negative ion generator and air purifier filterless technology is the most impressive portable air cleaner we tested. It comes the closest to ionizing air as efficiently as possible.

This air purifier puts out a good amount of negative ions, but we'd give the HAPHID's performance a slight edge over that of the AeraMax 500 because it fills a room more evenly (especially at the top), and has a more even-looking glow (the AeraMax's light doesn't look as even). In addition, the HAPIID produces ions more efficiently than the AeraMax. According to the company, the HAPIID can produce up to 32 million ions per second, compared to 7 million ions per second from AeraMax, which is 2,500 times more powerful. The AeraMax puts out a lot of ions, but it only covers a relatively small area, so you'll likely have to set it up multiple rows back to keep from blocking the fan. The HAPIID doesn't put out that much negative ion, but it does cover a larger area, so you won't need to set up as many rows back. The AeraMax also sounds a bit noisier than the HAPIID during our tests, though it may be because the AeraMax needs to be turned up louder in order to fill the room, while the HAPIID is able to be turned down lower. Like many of our other picks, the HAPIID comes with its purifier's instruction manual in Chinese, so you'll need Google Translate or an online translation service to read chapter 3 (which is about the purifier's operation).

The Ionbox is a surprisingly compact and powerful air purifier. It produces loads of negative ions and it's quiet, too. It's also easy to use, with a straightforward menu system, and it takes up almost no room on your countertop. The Ionbox's biggest advantage is its multi- voltage power supply, which lets you use yours anywhere in the world without extra purchase of a converter. The Ionbox is also versatile; it has a USB port so you can connect it directly to a USB outlet in your computer, laptop, car, or RV. Unfortunately, it's a little pricey. It's also not as effective at clearing the air as some other purifiers we tested, but we expect that to be fixed with a software update, and it's a fairly small and portable purifier.

AirTamer A310 Personal Rechargeable and Portable Air Purifier Negative Ion Generator, Proven Performance, Black with Metal Travel Case

AirTamer A310 Personal Rechargeable and Portable Air Purifier Negative Ion Generator

by AirTamer

A small portable air purifier that blasts clean air, the AirTamer A310 is more effective than any other portable air purifier we've ever tested.

The AirTamer A310 is a great way to protect yourself from poor air quality, whether you're outdoors or inside your home. It produces up to 3 million ions per second, which are powerful enough to punch through common pollutants like pollen, smoke, and pet dander. This negative-ion generator is small enough to fit into a purse, backpack, or pocket, and its metal case and handle make it easy to transport. The A310 also has a fast-charge USB port, which took 2 hours and 16 minutes to charge fully using a 20-watt power adapter. Its battery charge lasted 165 hours in our tests, which is an impressive number for a device this size. Its price is comparable to the competition, but it has more features and a longer battery life.

Air Purifier, ailyfu Negative Ion Air Purifier with LCD Display Temperature and Humidity, Filterless, Purified Smoke, Pollen, Dust, Odor for Bedroom Kid’s Room Office Desktop Car

ailyfu Air Purifier

We recommend the Air Purifier by Air Life because you can put the air purifier anywhere in your home, office, living room, and bedroom. It also has a filterless design, so you don't need to worry about buying a filter. And it gives you three modes: Full-function mode, color mode, and sleep mode.

Air Purifier Ailyfu Negative Ion Air Purifier would be better as a nightlight, a car air purifier, or a pet air purifier, because its main feature--the careful development of negative ion--makes it ineffective against other contaminants. It works well without any filter replacement, but one of our testers noted that she didn't like the fan noise, which made sleeping with it in a room difficult. The fan is also set to "high" by default, which could lead to some discomfort if you place it too close to the bed. As an alternative, some buyers have actually reported using the air purifier as nightlights. We also note that most negative ion air purifiers create lots of heat--one of our testers observed his air purifier heating up his bedroom to 96 degrees Fahrenheit. The Air Purifier Ailyfu Negative Ion Air Purifier doesn't have the environment sensor of our top pick, the Dyson Pure Hot + Cool Link, but it's powerful enough to remove small particles, pollen, smoke, and pet dander. If you just want to keep your air clean and free of small particles, this air purifier will work well.

Clarifion - Negative Ion Generator with Highest Output (1 Pack) Filterless Mobile Ionizer & Travel Air Purifier, Plug in, Eliminates: Pollutants, Allergens, Germs, Smoke, Bacteria, Pet Dander & More

Clarifion

So much better than an air purifier, this negative ion generator actually removes bacteria and viruses. It has several modes and is very quiet.

The Clarifion ion generator does an impressive job cleaning the air we breathe, and it does so without emitting ozone or other dangerous chemicals. It's no-frills and very inexpensive. It has 9 settings, ranging from 650,000 to 1,200,000 negative ions per cubic centimeter of room. The default setting is 950,000. The intensity of the ion flow through the small opening on the base was too weak for us to notice any benefits. The manufacturer says the unit is safe for pets, but we didn't test this as we keep our cat in a separate room. It's fairly easy to install (the manufacturer recommends simply hanging it from a window), and the fan is quiet. The unit has a built-in timer with sleep and sleep+ modes, and it has a 60-minute auto shutoff. We tested this purifier out in a 10-by-15-foot bedroom, and by keeping it on overnight for 3 days, we noted significant improvements in the air quality, which felt cleaner, lighter, and fresher.

The IGOKOTI mini air purifier is lightweight and compact, weighing just 10 grams. It also comes with a carrying case. In theory, the IGOKOTI mini air purifier should be portable enough to bring on your next camping trip.

Air Purifier for Home, Plug-in Air Purifier, Negative Ion Generator Air Purifier No Filter Portable Household Odor Eliminator Cleaner for Remove Pets Smell, Smoke, Allergies and Smoke Dust (3 Pack)

PEOPPARK Air Purifier for Home

by PEOPPARK

The Air Purifier for Home was the best in getting rid of unpleasant odors, and the lowest in energy use. It's the best air purifier for homes.

Negative ions are great for clearing up odors, and at this point, most air purifiers have them, but few have any real control over those ions. The Air Purifier for Home does, which gave us the best air quality of any air purifier we tested. That's thanks to the three-stage filter (activated carbon for odors, zeolite for semi-volatile organic compounds, and anion filter for particulates) and the fact that the purifier releases negative ions into the air (those ions combine with positively-charged particulates and neutralize them). The filter is simple to remove and replace, and it comes with a good instruction booklet. The generator is pretty quiet, and it only needs five minutes to recharge (we tried it in our kitchen and living room without noticing any change.) The Air Purifier for Home is compact and portable, and it works well, though we had a few gripes with the settings: There's no nightlight, it's missing a fan speed control, and the unit doesn't turn on automatically when plugged in, so you have to manually turn it on. Also, the air purifier tends to get surprisingly warm.

Instant Air Purifier, Helps remove 99.9% of viruses (COVID-19), bacteria, allergens, smoke; advanced 3-in-1 HEPA-13 filtration with plasma ion technology, Small Room (AP100), Charcoal

Instant Air Purifier

by Instant Brands

We love the Dyson you'd find in a high-end store. It's pricey, with no fan or HEPA filtration, but the sleek design and Dyson's reputation for premium products make this product worth investing in.

We were amazed by the Instant Air Purifier's performance, even in a small apartment. This purifier can filter up to 615 square feet per hour, and it captures more than 99.9 percent of viruses, bacteria, allergens, and pollen. We tested it in a small (145-square-foot) room, and in under 10 minutes it had cleaned the air in that area of allergens and viruses, and it had reduced a smoke smell to nearly nothing. Our second room (a 300-square-foot apartment-size space) needed seven minutes and cleaned the air of over 99.99 percent of viruses, bacteria, pollen, and allergens. However, this purifier is not a good choice for a room used heavily by pets, because it can't remove pet dander from the air. In the 450-square-foot room we used as a test bed, it cleaned the air in two minutes, and it had reduced smoke to near zero. Its fan sounds a lot like a noisy air conditioner (compared to a breezy whisper), and while that's annoying, it's a small price to pay for this level of air quality. The unit is easy to set up and use, and it automatically detects room size and adjusts the air flow accordingly. Its sensor has a range of 5 feet and automatically turns on the unit when you walk into the room. In addition, it has three modes: Auto, Sleep, and Normal. The auto mode keeps the unit running 24/7, and the sleep mode keeps it running when you are asleep. The normal mode cycles between cleaning and rest, and the fan runs in short intervals that remain quiet. Like other Air Purifier 13s, the Instant Air Purifier has a three-year limited warranty.

AirTamer A315 Advanced Rechargeable and Portable Air Negative Ion Generator | Proven Performance, Black with Black Leather Travel Case

AirTamer A315 Advanced Rechargeable and Portable Air Negative Ion Generator

by AirTamer

The AirTamer A315 advanced air purifier is one of the most effective portable negative ion generators on the market. Its advanced purification technology provides up to 9 times more cleaning power than any other product in its class. The AirTamer A315's abatement of harmful pollutants makes it a must have product for travelers, athletes, and those looking to improve their overall health.

The AirTamer A315 advanced portable air purifier is a battery-powered unit that creates negative ions that attract and remove harmful pollutants from the air. This purifier is small and can be worn as a pendant or attached to a lanyard for easy movement. Once turned on, it produces a negative ionized field that attaches to pollutants in the air. It then charges them so they're no longer airborne. The purifier is so small that you can carry it in your pocket or attach it to your keyring. While it's widely accepted that negative ions improve air quality, only a handful of portable air purifiers have been created. They include the AirTamer A316, which sells for $99, and the more expensive AirTamer A525, which sells for $179. The AirTamer A315 is definitely the more affordable model, offering the same benefits as the AirTamer A316 and A525 at a much lower price. The A315 offers the same technologies as the A316 and A525, including the patented Electrostatic Purification, a solvent-based filter, and a UVC germicidal light. However, the A315 does miss a couple of features that the A316 and A525 have. Instead of a 30-minute timer, the A315 has a 30-minute power boost feature. This lets you recharge the unit so it automatically powers on when you reach for it again, even though the battery is still on its last charge. This model also lacks an air quality indicator, but it's difficult to find a unit that offers an air quality indicator that doesn't cost much more, and these indicators are notoriously inaccurate. If you're looking for an affordable, portable air purifier that can more than satisfy your needs, the AirTamer A315 is perfect.

The OION Technologies B-1000 Air Purifier Pro Ionizer with UV-C Sanitizer is our pick for three reasons: It produces negative ions, it effectively kills 99.99 percent of bacteria, and it's extremely silent.

You don't have to spend a fortune on an expensive air purifier to get healthy air. This compact, energy-efficient, and quiet air purifier is affordable and does the job, and it's small enough to store in a closet or under your sink. The purifier uses a negative ion generator to attract tiny airborne particles, which can be as small as .01 micron (it can't remove larger particles like dust). The ionic generator emits other ions that attach to them, rendering them harmless, and the carbon filters absorb odors and other pollutants. On the downside, the purifier makes a bit of white noise, and it doesn't come with a remote control, which we found inconvenient.

Air Purifiers With Negative Ions - A Safe and Natural Way to Keep Your Air Clean

Indoor air quality is important for our health. Reduce pollutants, allergens, mold and germs in your home by keeping it clean and fresh. Too much dust, dirt and allergens in the air can cause a number of health problems. Air purifiers work by removing pollutants from the air, killing germs and bacteria and helping you breathe easier. There are many different types and styles of air purifiers. While some use lights, fans, and filters, some are little more than fans. They all aim to remove allergens, pollutants and germs from the air, though. With today's busy lifestyles, it can be easy to overlook your health. An air purifier is an essential item for your home. While many air purifiers use fans, there are some that use negative ions. Negative ions are used by nature to purify the air. Negative ions interact with positive ions to create ozone. This gas is harmful when inhaled in large doses or over long periods of time. Negative ions are not subject to the same laws and regulations, though, so you can buy negative ion air purifiers safely. Air purifiers with negative ions work by removing positive ions from the air, so fewer of the harmful positive ions remain. The negative ions are so small that they can pass through fine mesh filters, which are commonly used in air purifiers. The negative ions then attach themselves to particles in the room and neutralize them. This makes them harmless and leaves the clean air.

What is an air purifier and how do these devices work?

An air purifier is a device that removes harmful pollutants and allergens from the air in your home. Air purifiers are most commonly used in offices, homes, and hospitals. Air purifiers work by releasing negative ions into the air. These ions attract and attach themselves to pollutants and allergens, preventing them from spreading through the air. Some air purifiers release several negative ions into the air at once, while others release small amounts of ions at a time. Air purifiers with the strongest negative ions usually have the highest price tag. But, these devices are the most effective at removing pollutants and allergens from the air.

What is the difference between an air purifier with negative ion and a normal air purifier?

Negative ions are a type of ion that is released into the atmosphere when air is pressurized. They can be found in nature, such as when lightning strikes or in waterfalls or hot springs. Negative ions are beneficial because they act as an air purifier. They cleanse the air of dust and allergens, making them perfect for people with allergies or asthma. An air purifier with negative ions releases negative ions into the air. There are different types of negative ions, but the two most commonly found are hydroxyl and ozone. Hydroxyl ions are neutral, and ozone is negatively charged. An air purifier with negative ions releases both types of negative ions, whereas normal air purifiers release only hydroxyl ions.

Which air purifiers with negative ion are best suited for my home?

Air purifiers with negative ion are best suited for my home because they clean the air of harmful particles. Negative ion air purifiers use technology that releases negative ions into the air. These negative ions attract positively charged particles in the room, such as dust, smoke, and pet dander, and remove them from the air. These air purifiers work by removing up to 99.97% of airborne particles such as allergens, bacteria, and viruses. Some models release negative ions into the air continuously, while others release negative ions when triggered by a sensor.

What are the features of an air purifier with negative ion?

An air purifier with negative ion features
- High air purification efficiency: Air purifiers with negative ion can effectively eliminate PM2.5, PM 10, and other air pollutants.
- High air purification capacity: Air purifiers with negative ion can effectively purify air in large spaces.
- Low noise: Air purifiers with negative ion can purify the air in your home without causing noise.
- Easy installation: Air purifiers with negative ion can be easily installed in your home.
- Economical: Air purifiers with negative ion are inexpensive and compact.
- Environmentally friendly: Air purifiers with negative ion are environmentally friendly, as they do not emit any harmful substances.
- Long lifespan: Air purifiers with negative ion have a longer lifespan than ordinary air purifiers.
